GENERAL INFORMATION

Before your ambiente a1/a2/a3/a4/a4 H2O/a5/a7/a8 stove is assembled and

installed you should meet with the master chimney sweep responsible for

such matters in your area. He will advise you on the building regulations

and suitability of your chimney and will carry out the acceptance test on

your stove. Calculation of the dimensions of the chimney is based on DIN

EN 13384 using the triple values contained in this manual (see Technical

Data).

Important for young children, the elderly or the frail: As with all other

heating appliances, a guard should be fitted to protect the above persons

because both the glass door and the stove cover panels can become very

hot in use. Caution: Risk of burns! Never leave such individuals unsuper-

vised near a stove when it is lit or when the fire has just gone out. As a

basic rule, the stove should not be left unattended for long periods of time

when lit.

The protective glove supplied is designed only for protection from

heat when operating the control handle and the cold hand. The glove

is not fireproof.

When assembling and operating your stove and when connecting it to the

chimney you must ensure that you comply with national and European

standards, the relevant country-specific and local guidelines and regula-

tions and, in Germany, the relevant Heating Regulation (FeuVO) of the state

where you live.

The stove should always be operated with the door closed. Modifying the

closing system is not permissible.

1. TESTED QUALITY

OUR STOVES ARE TESTED TO DIN EN 13240. THE DECLARATION OF PER-

FORMANCE MAY BE VIEWED AND IS OBTAINABLE FROM WWW.SPARTHERM.

COM

This stove has a self-closing firebox door, and so the door is only ever

opened for operating purposes (e.g. cleaning the firebox or putting on more

wood). For safety reasons, tampering with the closing mechanism is not per-

missible and will void the warranty and the operating permit. The warranty

and the operating permit will also be voided if any technical modifications

are made to other parts of the stove.

1.2. DAMAGE IN TRANSIT

Please inspect the goods immediately upon delivery (visual check). Any

damage should be noted on your delivery note. You should then inform

your stove fitter. Protect the visible parts of the stove from dirt and damage

during installation.

Only approved and sufficiently strong handling aids should be used to trans-

port your stove. The following points must be noted to ensure safe transport

without any problems:

• The stove should always be transported in the upright position or tilted

slightly backwards (the back of the stove is labelled).

• A hand truck used as a handling aid must load the stove from the rear

only.

2. INSTALLATION INSTRUCTIONS

The assembly and installation of your ambiente a1/a2/a3/a4/a4 H2O/a5/

a7/a8 stove should be carried out by a specialist. Before your stove is

assembled and installed you should meet with the master chimney sweep

responsible for such matters in your area to discuss the suitability of your

chimney and the installation location and to clarify other matters.

2.1. GENERAL REQUIREMENTS FOR INSTALLATION

All relevant national and European standards and local regulations (DIN,

DIN EN, state building regulations, heating system regulations, etc.) must

be noted and observed when installing, connecting up and operating the

ambiente a1/a2/a3/a4/a4 H2O/a5/a7/a8. Selected relevant regulations are

listed below. This list does not claim to be complete.

FeuVo / LBO / VKF Heating System Regulations of the relevant federal state / state

Art. 15a Art. 15a B-VG (Austria)

This list of regulations and requirements does not claim to be complete.

Fireplaces should only be installed in rooms and at locations where the

position, structural conditions and type of use will not create any hazards.

The floor area of the room where it is installed must be of such a type and

size that the fireplace can be correctly operated in accordance with the

instructions.

The ambiente a1/a2/a3/a4/a4H2O/a5/a7/a8 stove is a non-room air sealed

(open flue) fireplace. Problems may therefore arise if the stove is operated

at the same time as a ventilation system such as a kitchen extractor hood

or bathroom fan. Appropriate measures should be taken in such cases to

ensure that the stove can be operated safely (pressure monitor, door contact

switch, etc.).

These safety precautions do not apply in the case of a room air sealed

appliance (ambiente a1/a2/a3/a4/a4 H

O RLU).

2.1.1. INSTALLATION LOCATION

Your ambiente a1/a2/a3/a4/a4 H2O/a5/a7/a8 stove must not be installed:

1. In stairwells and landings, except in residential buildings with no more

than two flats.

2. In corridors accessible to the public

3. In garages.

4. In rooms or flats that are vented by ventilating systems or hot air sys-

tems using blowers, unless the safe operation of the stove is ensured.

5. In rooms where highly flammable or explosive substances or mixtures

are processed, stored or manufactured in such quantities that ignition or

explosion would be hazardous.

2.1.2. MULTIPLE USAGE

Multiple usage of the chimney in accordance with DIN 18160 is possible as

the ambiente a1/a2/a3/a4/a4 H

O/a5/a7/a8 stove has a self-closing firebox

door (a1). However, multiple usage must always be discussed and agreed

in advance with the master chimney sweep responsible for such matters in

your area. Note that all fireplaces connected to the same chimney must also

be approved for multiple usage.

2.3.3. FITTING THE STORAGE STONES

ambiente a3/a4

Storage stones can only be fitted or retrofitted to the ambiente a3 and a4

models.

If the ambiente a3 or a4 is ordered with storage stones, the front stone

and supporting plate are already fitted at the factory. For weight reasons,

the other storage stones are assembled on site. Stoves are supplied with

a rear flue gas connection as standard, unless otherwise specified at the

time of ordering.

To install the storage stones, start by removing the cover. Note that the

stove should not yet be connected to the chimney when doing this.

Fitting the front stone:

(only if retrofitting storage stones) Start by installing the front stone (A).

Next, fit the supporting plate (B) (Fig. 6a).

Fitting the storage stones:

ambiente a3 with top and side flue gas connection: Place the three shallow

stones in position to form a ring and replace the cover (Fig. 6b).

ambiente a4 with top flue gas

connection:

Start by placing the six tall stones

in position to form a ring. These

have a recessed handle on the

inside to facilitate assembly. Now

place the three shallow stones in

position to form a ring and replace

the cover (Fig. 6c).

ambiente a4 with side flue gas

connection:

Start by placing the two small

stones under the flue gas pipe,

and then place the four tall stones

in position. These have a recessed

handle on the inside to facilitate

assembly. Now place the two shal-

low stones in position and replace

the cover (Fig. 6d).

Fig. 6c

Fig. 6dFig. 6a Fig. 6b

Controlling the heat output to the

storage system:

(ambiente a3 and a4 only)

The heat output to the storage stones

can be controlled via the adjustment

lever (Fig. 6e). If the adjustment

lever is moved to the ‘+’ position,

the convective heat is transmitted

directly from the stove to the room.

The room will warm up faster at this

setting. If the adjustment lever is set

to the ‘-’ position, the convective heat

will remain in the storage stones for

longer. The heat is stored in the stove and slowly released to the room after

the fire has gone out. The stove will continue to provide a cosy warmth even

when the fire has gone out.

ambiente a5

The ambiente a5 stove can be optionally fitted with storage stones for pro-

longed heat storage. Proceed as follows to fit the stones: In order to fit

storage stones to the ambiente a5 stove, the first step is to remove the stove

top cover (Fig. 7a).

Now push the ‘front’ storage stone (WxHxD 310 mm x 285 mm x 30 mm)

into the front locating slot (Fig. 7b). Next, place the two ‘back’ storage

stones (WxHxD 250 mm x 390 mm x 30 mm) in the locating slot at the rear

of the body (Fig. 7c). Place the ‘top’ storage stones (Fig. 7d - 7h) on the top

Fig. 6e

Fig. 7a Fig. 7b

Fig. 7c Fig. 7d

plate of the stove body, according to whether the stove has a top or rear flue

gas connection. (This example shows a rear flue gas connection). After put-

ting the storage stones in position, replace the stove top cover. (Fig. 7i - 7j)

2.4. COMBUSTION AIR SUPPLY

The combustion air supply can be provided in various ways as described in

sections 2.4.1, 2.4.2 and 2.4.3.

2.4.1. NON-ROOM AIR SEALED OPERATION (RLA)

Your ambiente a1/a2/a3/a4/a4 H2O/a5/a7/a8 stove draws the air it needs for

combustion from the room where it is installed (non-room air sealed opera-

tion). An adequate supply of fresh air must be ensured in the room where the

stove is installed (for further details refer to the heating systems regulations

for the country concerned, DIN 18896, the technical rules, etc.) The installer

and the operator of the stove should check the fresh air supply. An adequate

air supply for combustion must be ensured when several fireplaces are oper-

ated in one room or in connecting rooms. If the windows and doors are sealed

(e.g., in connection with energy-saving measures) the fresh air supply may

be restricted and that can adversely affect the stove’s draught. This can be

detrimental to your health and also, in some cases, to your safety.

If necessary, an additional air supply can be provided by fitting an air inlet near the

stove or by fitting a combustion air intake pipe which connects with the external

air (refer to section 2.4.3 Separate Combustion Air Supply on page 16) or with a

well ventilated room (not the room where the stove is installed). In particular, it

must always be ensured that the necessary combustion air intakes remain oper-

ational when the fireplace is in use. Note that operating a ventilating system at

the same time, e.g. an extractor hood or bathroom fan, in the same room or in

a connecting room can adversely affect the operation of the stove (even causing

smoke or flue gas to leak out into the room, despite the firebox door being closed).

Ventilating devices must therefore not be operated at the same time as the stove

unless suitable measures are taken to maintain the air supply to the stove.

Fig. 7e

Fig. 7h

Fig. 7f

Fig. 7i Fig. 7j

2.4.2. ROOM AIR SEALED OPERATION (RLU)

Your ambiente a1/a2/a3/a4/a4 H2O RLU stove does not draw the air it needs

for combustion from the room where it is installed (room air sealed oper-

ation). Combustion air intakes and pipes must not be obstructed or closed

unless special safety devices are fitted to ensure that the stove can only

be operated when the closing system is open. The cross-section must not

be reduced by means of an obstructor or grille. According to EnEV, the

combustion air pipe should be fitted with a shut-off device. The position of

the shut-off device must be obvious from the outside of the connecting pipe.

This measure is not necessary with balanced flue systems. The combustion

air intake pipe should be insulated to prevent moisture from the ambient

air from condensing on the pipe. Also, when fitting the pipe it should be

ensured that no water or other substances can enter the ambiente a1/a2/

a3/a4/a4 H

O RLU stove and that any condensate can drain away outside.

According to the relevant provisions, combustion air ducts that bridge

firewalls in buildings with more than two full storeys must be constructed

such that fire and smoke cannot spread to other storeys or fire lobbies.

The national and local fire precautions for the place of installation must be

observed. Please ensure that the pipework is always leaktight.

2.4.3. SEPARATE COMBUSTION AIR SUPPLY

It is possible to provide the stove with a separate combustion air supply. The

separate combustion air connection is located at the rear of the unit and in

the lower compartment (D = 100 mm) at the sides. The connecting piece

is ready-assembled. The stove covering can be opened up for the purpose

(unscrew the cover cap) and the connecting piece can be screwed on. If a

pipe connection is attached to the combustion air coupling, the combustion

air is drawn into the stove from outside or from other rooms such as the

basement. When connecting up the stove to a combustion air pipe, the

requirements of TR-OL (technical rules), DIN 18896, etc. must be observed

and applied. In particular, sufficient dimensioning of the pipes must

be ensured.

If using a swivel connector, a permanently flexible connection must

be made. The rotating action must not be restricted.

Combustion air intakes and pipes must not be obstructed or closed unless

special safety devices are fitted to ensure that the stove can only be

operated when the closing system is open. The cross-section must not

be reduced by means of an obstructor or grille. If the combustion air pipe

has to be routed out of the building, a shut-off device must be fitted. The

shut-off device must be identifiable from outside. In the case of an external

connection the pipe should be insulated, as condensate may form. Also,

when fitting the pipe it should be ensured that no water or other substances

can enter the stove and that any condensate can drain away outside. Please

note that room air sealed operation of the stove is not possible with a sepa-

rate combustion air supply. That means that appropriate safety precautions

must be taken if operating an extractor fan or cooker hood when the stove

is in use.

According to the relevant provisions, combustion air ducts that bridge

firewalls in buildings with more than two full storeys must be constructed

such that fire and smoke cannot spread to other storeys or fire lobbies.

The national and local fire precautions for the place of installation must be

observed.

Special instructions for the ambiente a7/a8

It is possible to provide the stoves with a separate combustion air supply. The

separate combustion air connection is located at the rear of the stove (a7 only)

and on the underside of the stove (D = 100 mm). Proceed as follows to connect

up the combustion air supply.

Installation on underside of stove (a7 and a8):

Stand the stove on the floor above the combustion air connection. Now care-

fully lift off the stove covering. (Fig. 8a). Next, unscrew the screw cap. (Fig.

8b). Connect the combustion air connecting piece to the flexible, extensible

combustion air duct installed on site. If the combustion air connection is

rigid at floor level, the separate combustion air connecting piece supplied

must be pushed into the connection to form an airtight seal.

Installation at rear of stove (a7):

Start by unscrewing the screw cap (Fig. 8d). Now fit the combustion air

connecting piece (Fig. 8e). Lastly, connect the combustion air connecting

piece with the combustion air duct.

2.5. FIRE PRECAUTIONS

General Information about Fire Precautions

Stoves are heating systems and are subject to regulations and essential fire

precautions. The fire precautions and minimum distances should be borne

in mind when selecting the installation location for the stove. A minimum

distance of 5 cm from the rear wall must always be maintained.

Greater distances should be allowed for reasons of safety and fire

prevention in the case of walls that need to be protected or combus-

tible building components.

The table that follows shows the distances that must be maintained accord-

ing to the type of stove and the installation situation on site. Use the draw-

ings (Figs. 9-11) to help you determine your particular installation situation

and note the distances that must be maintained.

Note the fire precautions when installing the stove. Ask your local

chimney sweep for advice.

• Their structure and materials enable non-combustible mounting walls

not in need of protection to be permanently exposed to temperatures

above 85°C. Combustible mounting walls in need of protection (e.g.

stud partition construction) must be protected from temperatures above

85°C.

The mounting walls should be assessed before installing the stove. If the

nature of the mounting wall cannot be identified with certainty, a specialist

(such as the chimney sweep) should be consulted.

• According to DIN 4102-1, wallpaper used as a wall covering is not con-

sidered a combustible building component and does not require any

special precautions.

• Please note that the minimum distances indicated from rear walls and

side walls need to be adapted for rotating stoves.

• It is important to observe the minimum distance from the chimney con-

necting piece to combustible building components (refer to section „2.7.

Connecting pieces“ on page 20).

• There must be no combustible objects within a radius of 50 cm above

the stove.

Floor coverings near the stove

Floors made from combustible materials in front of the firebox door must be

protected by a covering of non-combustible materials. This covering should

extend at least 50 cm in front of the stove and at least 30 cm at each side

(Figs. 9-11) (measuring from the firebox door or viewing pane).

There must be no combustible building components, furniture, curtains or

decorations within the radiant area of 80 cm (Figs. 9-11) in front of the

firebox door or viewing pane. That distance can be reduced to 40 cm if a

fire screen ventilated on both sides is placed between the fireplace and

any combustible objects. Before your stove is lit for the first time it must

undergo acceptance by the local chimney sweep. Your local chimney sweep

can/should advise you on the installation conditions before your stove is

installed and give you instructions on the correct installation of your stove.

Minimum distances from nearby building components

The distances indicated in the table below must be observed, according to

your stove’s viewing pane arrangement (see sketches below) and the nature

of the mounting walls. In the stove installation example shown in Fig. 9, if

dimension B is observed and dimension E measured on site is less than the

value indicated, then it is not necessary to allow for the radiant area with

respect to the side walls. However, if the side wall is longer than dimension

E, it must be decided on site whether this wall needs to be protected. The

position of the radiant area can be altered if necessary by increasing dimen-

sion A or dimension B.

2.6. SHUT-OFF DEVICES

Flue systems should be constructed in accordance with the Technical

Rules of the Stove and Hot Air Heating System Trade. It is permissible

for stoves to have a shut-off device in the flue system. This device must not

interfere with inspection and cleaning of the connecting piece and it must not

be of self-closing design. The status of the shut-off device must be obvious

from the outside, e.g. from the position of the control handle. Such devices

may only be fitted in the flue gas manifold, flue gas stack or connecting piece.

2.7. CONNECTING PIECES

Connecting pieces: Your ambiente a1/a2/a3/a4/a4 H2O/a5/a7/a8 stove is

connected to the chimney by 150 or 160 mm diameter connecting pieces

made from steel sheet at least 2 mm thick. These must comply with DIN

1298 or DIN EN 1856-2 and they must be connected to the chimney in

accordance with DIN 18160 or the regulations that apply in the country

concerned.

It is important to ensure that the flue gas pipe takes the shortest possible

route upwards towards the chimney. The number of bends in the flue gas

pipe should be kept to a minimum. In addition, the flue gas pipe should be

connected to the chimney by a wall lining that makes a seal with the wall

and the pipe. If necessary, the flue gas pipe should be fastened with clips

to hold it securely in place. If the flue gas pipe passes through components

made from combustible materials, the flue gas pipe must be insulated in

accordance with the regulations.

The basic rule is that the connecting piping should be installed in such a

way that it can be cleaned at any time. This should be ensured by providing

an appropriate number of cleaning apertures.

If the ambiente a1/a2/a3/a4 RLA is designed to rotate, the connecting pip-

ing should be installed in such a way that the fastening is not compromised.

The flue gas pipe must not turn when the stove rotates.

Depending on the information provided by the flue gas pipe manufacturer,

the minimum distance from the chimney connecting piece to combustible

components may increase the distance between the stove and combustible

building components. The minimum distances from combustible compo-

nents stated in this Manual refer to the stove, and should be adapted if

necessary (refer to section „2.5. Fire Precautions“ on page 18).

In the case of top flue gas routing, please note that a cleaning hatch must

be provided above the flue gas connecting pipe.

2.8. SWIVEL CONNECTOR

A swivel connector can only be used with the ambiente a1/a2/a3/a4 RLA

with top flue gas connection models and must be specified when ordering.

In this case the stove can be rotated 180°, i.e. 90° to the left and 90° to the

right. For operation of the swivel function refer to section „3.3 Functioning

of Swivel Connector“ on page 28).

2.9 INSTALLING THE WATER-HEATING COMPONENTS OF THE ambiente a4 H

Installation of the water-heating components, including fitting the neces-

sary safety devices, etc., should always be carried out by a specialist. The

ambiente a4 H

O should be installed in such a way that all water-carrying

components are always accessible and can be inspected at any time.

Note: The stove and all associated thermowells, connections,

structural parts and piping must be hydraulic pressure tested and

checked for leaks before commissioning.

2.9.1 ambiente a4 H2O PIPE CONNECTIONS

The pipes can be connected to the rear, inside or underside of the stove

(Figs. 12a-12c).

The connections are fitted with protective caps and brass plugs for trans-

port. The brass plugs are normally inserted into the connections on the

inside of the lower compartment. If the connection is to be made via the

base of the unit or through the floor, the brass plugs should be removed and

inserted in the rear-facing connections. The connections are labelled and

should not be used other than as indicated. In particular, the integral safety

device (safety heat exchanger) should not be used to heat water.

To facilitate installation of piping, etc., when making a connection through

the floor, an installation template can be downloaded from the dealer login

section of our home page at www.spartherm.com. Alternatively, we can

supply a paper print-out of a 1:1 scale installation template on request.

The Flex connection kit (order number 1016990) can be ordered from us for

straightforward, speedy connection of the pipework through the floor and

the internal connections.

2.9.2 BASIC REQUIREMENTS FOR INSTALLATION OF THE ambiente a4 H

The ambiente a4 H2O should only be installed in systems with a thermostatic

safety device to DIN 4751 or DIN EN 12828. The connecting pipes to the

heating system should always be laid in such a way that they can be discon

nected (e.g. screwed connection).

Before using the stove for the first time, both the heating components (heat-

ing system) and the water components (thermal discharge safety device,

safety heat exchanger) must be filled and vented. After filling it up, check

that all hydraulic connections are leaktight.

Operating the stove without connecting it to the water system will

cause irreparable damage and will void any warranty claims.

A type-tested safety valve (coded H) with a threshold pressure of max.

3.0 bar should be fitted in the flow pipe immediately next to the ambiente

a4 H

O. No shut-off devices must be integrated into the system between

the safety valve and the ambiente a4 H

O, as that would disable the safety

device. Also, all necessary safety devices should be integrated into the over-

all system in such a way that safe operation is ensured. A dedicated safety

valve must be fitted even if another safety valve is present elsewhere in the

overall system (note TRD 721).

The installation and operating instructions for the heating components /

additional components included in the system must be read and observed

when installing the stove.

2.9.3 THERMAL DISCHARGE SAFETY DEVICE ambiente a4 H

As the ambiente a4 H2O heating system cannot be quickly switched off auto-

matically, the water heat exchanger must be fitted with a thermal discharge

safety device according to DIN 4751 Part 2 or DIN EN 12828. A safety

device (safety heat exchanger) to prevent overheating is integrated into the

ambiente a4 H

O for this purpose. This safety device must not be used to

heat water.

The thermal discharge safety device (e.g. Watts, STS20/200) is not pre-as-

sembled to protect it during transport and installation. It will be found inside

the fire chamber at delivery and should be fitted to the correspondingly

labelled connection. After that, the capillary and adapter should be screwed

on to the thermal discharge safety device. This has been tested and

approved for a minimum water throughput of 900 kg/h.

The following points must be noted during installation to ensure that the

safety device will operate correctly.

• A flow pressure of min. 1.5 bar must be available at the cold water inlet.

That pressure must be guaranteed at all times. Fluctuations in the water

supply must be avoided. That means, for example, that a domestic water

supply which is dependent on the mains pressure is not permissible.

• A minimum water flow of approx. 900 kg/h must be ensured. It must not

be possible to shut off this supply.

• It must be ensured that cold water (5-20°) is always available. That does

not include the domestic water supply.

All safety-related components must be integrated into the system in such a

way that their function and leaktightness can be checked at any time. The

thermal discharge safety device water drain should be designed in such a

way that it can be inspected at any time (e.g., via an open drain with siphon

trap).

The cold water pipe should be flushed through before first using the system.

This will flush out any dirt that could interfere with the closing of the thermal

discharge safety device. The instructions and information provided by the

manufacturer of the thermal discharge safety device must be observed.

2.9.4 THERMAL PUMP CONTROL ambiente a4 H2O

A thermostatic switch (e.g. Afriso) is located in the bottom compartment for

optimum control of the circulating pump. This ensures that the circulating

pump will start up only when the water reaches the specified temperature

(>60°C). It is possible for the pump to be controlled via the boiler control

system or similar devices if the pump switches on when the temperature

exceeds 55°C. The maximum contact rating of the factory-fitted pump ther-

mostat is approx. 16 (4) A with a 250 V AC system.

The thermostat is factory-set to a temperature of approx. 62°C. The circu-

lating pump or the load unit will thus be switched on or off if the temper-

ature reaches or drops below the specified water temperature of approx.

60°C in the ambiente a4 H

O’s water heat exchanger. As an option, the

temperature can be adjusted by the installation contractor if circumstances

demand. This is done by adjusting the circular disc or removing the top

cover, according to the thermostat version. The temperature range can be

altered after removing the cover.

Please note: At water temperatures below 60°C there is a greater risk of

falling below the dew point. This can cause tarry soot to form. Also, cleaning

becomes necessary much more often. We therefore recommend setting the

temperature at which the pump switches on to a minimum of 60°C and a

maximum of 70°C.

2.9.5 ELECTRICAL CONNECTION

The entire electrical installation of the individual components of the heating

system must be carried out by an authorised specialist contractor. All work

must be carried out in accordance with VDE regulations (e.g., VDE 0105,

VDE 0116, VDE 0100, etc.) and the local electricity supplier’s technical

connection conditions.

The only work required on the ambiente a4 H

O is the electrical installation of

the thermostat for the load unit pump (refer to section „2.9.7 Load unit (heat

charger) in the ambiente a4 H

O stoves“ on page 26) and connection to

the domestic electricity supply. The temperature-resistant connecting lead is

approx. 3.0 m long and is already connected up inside the thermostat.

The blue wire, the switched phase (L‘) is wired as phase to the circulating pump or load unit.

The green-and-yellow wire is wired to the earth conductor (ground) (PE) of the mains cable.

The brown wire is wired to the phase (L) of the mains cable.

The functioning of the thermostatic switch can be checked before using it

for the first time with the aid, for example, of hot water from a kettle and

a thermometer. Note that the rear cover panel has to be removed in order

to do this.

2.9.6. CONNECTING THE ambiente a4 H2O TO A

HEATING SYSTEM

Please note: The entire heating system should be planned in detail in

accordance with the relevant rules of the art and the safety standards

before installing the ambiente a4 H

O as part of a heating system. The plan-

ning consultant or installation contractor doing the work is responsible for

ambiente a4 H2O

Fig. 14

Fig. 13b

the correct design of the pumps, fittings, piping and buffer tank used and

the safety components. We recommend minimum nominal dimensions for

heating pipes of: copper pipes: 22x1.0 mm or steel pipe: ¾". For cold water

pipes a nominal pipe size (copper pipe) of 15x1.0 and a flow pressure of 2.0

bar are sufficient for safe operation. Possible variant for integration of the

However, the pipes should be dimensioned by the specialist firm, taking

local conditions into account.

The ambiente a4 H2O can be integrated with reference to Figure 14.

A buffer tank must be included. The buffer tank volume should be calculated

according to BImSchV 1 and 2 (

see „2.2. Technical Data“ on page 7)

This specifies that 55 litres of buffer tank volume must be provided per kW

water output. For the ambiente a4 H

O that means: 5.7 kW x 55L/kW = 341L.

As this is not a standard size available on the market, the next largest buffer

tank with a capacity of 500 litres should be selected. The following sample

calculation may be helpful for dimensioning the buffer tank:

The following assumptions have been made:

• Buffer tank size: 500 litres (approx. 500 kg water)

• Initial water temperature in buffer tank: 40°C

• Final water temperature in buffer tank: 70°C

• Temperature differential 30°C (corresponds to 30 K)

• No heat is drawn from the tank while it is being heated by the

ambiente a4 H

Q = c

× m × ∆t

Q = 4,187 kJ × 500 kg × 30

Q = 62805 kJ

kg × K

So: The heat required to heat 500 litres of water in a tank from 40°C to

70°C is 62,805 kJ (= 62,805 kWs) (disregarding any losses or heat drawn

within the system). That corresponds to approx. 17.4 kWh.

Assuming that the ambiente a4 H2O has an average output of approx. 5.4

kW it will take about 3.2 hours to heat up the entire tank (500 L). This

calculation is based on heating up the entire volume in the tank uniformly.

In an efficiently designed heating system the hot water is stored in layers

in the buffer tank, e.g. in a stratified storage system. That way, hot water is

available after heating up for only a short time and heat is available for use

shortly after circulation starts in the ambiente a4 H

O. Only surplus energy

not needed for heating is then stored in the buffer tank.

On very cold winter days an ambiente a4 H

O may sometimes be in oper-

ation for about 12 hours. The quantity of heat thus produced then corre-

sponds theoretically to 65 kWh. That quantity of heat would heat approx.

1,900 litres (from 40°C to 70°C). As a rule, though, heat is always drawn

off in such a situation and so overheating of the buffer tank (> 90°C) will

not occur.

This calculation does not take account of material heating occurring in the

buffer tank and pipes or radiation losses from the system components, etc.

Such factors extend the buffer tank heating-up time in practice.

2.9.7 LOAD UNIT (HEAT CHARGER) IN THE ambiente a4 H

O STOVES

As a general rule, the ambiente a4 H2O may only be operated with a load

unit (heat charger). In operation, the supply flow temperature should be at

least 65°C and the return temperature at least 62°C. In order to ensure that

these temperatures are guaranteed, a circulation pump / load unit (heat

charger) are to be installed in such a way that they will only start-up when

the temperature has reached 62°C. To reduce the danger of overshooting

the dew point, a “controllable” load unit (heat charger) is generally to be

installed. This involves capturing the control variable, which corresponds to

the effective return temperature at the entry to the water heat exchanger,

and adjusting it to the desired value.

We recommend the use of the load unit (heat charger) type LTC 141 from

the company ESBE, which is optionally available, or a comparable load unit

(heat charger). The use of other solutions (e.g. a four-way mixer) has not

proved successful in practice and is, therefore, not recommended.

We cannot accept any liability nor provide guarantee cover for any mal-

functions (sooting, deposits, etc.) or corrosion damage to the water heat

exchanger or chimney etc. that are due to a missing or non-effective load

unit (heat charger).

3. OPERATING INSTRUCTIONS

Read these Installation and Operating Instructions through carefully before

installing or operating your stove. Make sure all objects are removed from

the fire chamber and the ash pan (except for the fire chamber lining).

Ask your specialist dealer to explain to you how to operate the ambiente

a1/a2/a3/a4/a4 H

O/a5/a7/a8 stove and how it functions. National and

European standards and local regulations must be observed when operating

this fireplace.

3.1 GENERAL OPERATING INFORMATION

• Young children, the elderly or the frail: as with all heating appliances,

a guard should be fitted to protect the above persons because both

the glass door and the stove cover panels can become very hot in use.

Caution: Risk of burns! Never leave such individuals unsupervised near

a stove when it is lit or when the fire has just gone out. Please make

them aware of this hazard.

• The protective glove supplied is designed only for protection from heat when

operating the control handle and the cold hand. The glove is not fireproof.

• Never place any combustible objects on the exposed surfaces or cover

panels of the ambiente a1/a2/a3/a4/a4 H

O/a5/a7/a8 stove. Never dry

washing on the stove. Racks for drying washing should always be placed

outside the radiant area of the stove.

• Burning fuel releases thermal energy which heats up the various parts

of the stove, such as the surfaces, the door, the door handle and control

handle, the viewing pane, the flue ducts, etc. These parts can get very

hot. Always take appropriate precautions when touching or operating hot

stove parts (e.g. use the protective glove).

• The ambiente a1/a2/a3/a4/a4 H

O/a5/a7/a8 stove must always be

operated with the firebox door closed. The door should always be kept

closed, even when the stove is cold. The only times the door should be

opened are when lighting the stove, when putting on more wood or when

cleaning the stove.

• Do not modify the stove in any way. In particular, no parts that have

not been expressly approved by Spartherm shall be placed in the fire

chamber or in the flue gas or combustion air paths. Any modification to

the fireplace without such express approval will void the warranty and

operating permit.

• Extractor hoods, ventilators, etc. used at the same time as fireplaces in

the same room or in an adjoining room may interfere with the correct

functioning of the open flue stove (smoke may even escape into the

living room). Such ventilation systems should never be operated at the

same time as the stove unless appropriate precautions are taken.

• This stove has been designed for non-continuous use. It is not possible

to achieve continuous operation, even by shutting off the air supply,

and attempting this is not permissible. A longer heating period can be

achieved by the appropriate addition of more fuel.

ambiente a4 H

O only:

• Do not place any combustible materials in the lower compartment of

the stove cover.

• Due to the low flue gas temperatures, a suitable flue gas system is

necessary (such as the Alkon made by Raab).

3.2 FIRE PRECAUTIONS

Refer to section „2.5. Fire Precautions“ on page 18.

3.3 FUNCTIONING OF SWIVEL CONNECTOR

A swivel connector can only be used with the ambiente a1/a2/a3/a4 models

with top flue gas connection and must be specified when ordering. The

connector enables the stove to be rotated 180°, i.e. 90° to the left and 90°

to the right (Fig. 15a).

To rotate the stove, turn the lever (see Fig. 15b). After rotating the stove to

the desired position, raise the lever and turn it to the right to lock the stove

in position (see Fig. 15b).

4. COMBUSTION

4.1 LIGHTING THE STOVE FOR THE FIRST TIME

The ambiente a1/a2/a3/a4/a5/a7/a8 stove must be assembled and installed

by a specialist contractor. Commissioning must always be carried out by an

expert from the installation firm. The owner / operator of the system must be

handed a certificate stating that the system has been properly installed and

all control and safety components have been correctly set and are operating

correctly (see sample in section „9.1 Commissioning report for ambiente

a1/a2/a3/a4/a5/a7/a8“ on page 46).

Only a moderate fire should be lit when using the stove for the first time. That

way, you avoid cracking the fire chamber lining (the lining may still contain

residual moisture at commissioning). Slowly increase the heat output the

next 3 to 5 times the stove is lit, up to about 30% above the nominal output,

to allow the anti-corrosion coating on the surfaces to burn in correctly. The

wood consumption will be approx. 2.5kg/h for a typical combustion period

of about 45 minutes. That corresponds to 1.8 kg wood per combustion

cycle, though the actual combustion duration can vary according to local

conditions. The colour of the coating may mellow slightly during this pro-

cess. Do not place any objects on the ambiente a1/a2/a3/a4/a5/a7/a8 and

do not touch the stove. An unpleasant odour, which is harmless to health,

may be given off during this process (sometimes accompanied by a small

amount of smoke). It is therefore important to ensure that the room is well

ventilated during the burning-in process. Open all the doors and windows

to let fresh air in.

Please note that slight expansion or contraction noises may be heard as the

stove heats up or cools down. Such noises occur as the material expands at

high temperatures, and are not a cause for concern.

4.1.1 COMMISSIONING THE ambiente a4 H2O

Heating systems must always be installed and set up by specialist con-

tractors. Commissioning must always be carried out by an expert from the

installation firm. The owner / operator of the system must be handed a

certificate stating that the system has been properly installed and all control

and safety components have been correctly set and are operating correctly.

Commissioning must not take place until all the necessary components have

been connected up, all necessary safety devices have been integrated and

are operational, the water heat exchanger has been filled and the system

has been vented. It is not permissible to operate the system without water,

when only partly filled or with safety devices that are not operational. It

may be necessary to vent the water heat exchanger several times at com-

missioning (refer to Figure 12b/12c, section „2.9.1 ambiente a4 H

O pipe

connections“ on page 21).

The operator must also be given detailed instructions on the operation,

functioning and maintenance of the entire system including all additional

components. The measures necessary to keep the system operating safely

must also be explained to the operator. Operator instruction must be docu-

mented in the commissioning record. The Installation and Operating Manual

should be kept in an easily accessible place near the ambiente a4 H

Before commissioning it is important to check whether any objects are still

inside the fire chamber or in the ash pan. If so, remove them.

The stove is supplied with a ceramic fibre mat 3-5 mm thick on top of the

baffle plate of the fire chamber lining. This is needed to soak up any con-

densate occurring the first three times the stove is lit. Before lighting the

stove, check that the mat is lying snugly on top of the fireclay baffle plate. If

the mat is not in position, condensate can drip on to the fire chamber lining,

leaving permanent stains. The fibre mat can be removed after the stove has

been lit 2 or 3 times. Also, dirty condensate may leak from the bottom of

the fire chamber and may soil or damage the floor underneath the stove. An

absorbent material should therefore be placed under the stove the first few

times it is used, until there is no more condensate leakage.

Only a moderate fire should be lit when using the stove for the first time

(approx. 1.5 kg/h) to avoid cracking the fire chamber lining. There may still

be some residual moisture in the lining when the stove is lit for the first time.

That moisture can escape, e.g. via the air connection box and the rear wall,

the first few times the stove is lit. It is important to ensure that the fibre mat

is correctly positioned on top of the baffle plate. That way, the condensate will

be absorbed before it drips on to the fireclay and possibly causes stains. The

air inlet should be open during this time.

Slowly increase the heat output the next 3 to 5 times the stove is lit, up to

about 20% above the nominal output (wood consumption approx. 2.6 kg/h)

to allow the anti-corrosion coating on the surface of the stove to burn in cor-

rectly. An unpleasant odour, which is harmless to health, may be given off

during this process (sometimes accompanied by a small amount of smoke).

It is therefore important to ensure that the room is well ventilated during

the burning-in process. Open all the doors and windows to let fresh air in.

Please note that slight expansion or contraction noises may be heard as the

stove heats up or cools down. Such noises occur as the material expands at

high temperatures, and are not a cause for concern.

4.2 CONTROLLING THE COMBUSTION AIR SUPPLY

The combustion air supply is infinitely adjustable with the aid of the air

adjustment lever, which is located below the door (see Fig. 16). The lever

must be operated with the firebox door closed.

Air supply open: When lighting the stove or when adding more wood, move

the lever all the way to the right. That delivers the maximum combustion air

flow to the firebox as primary air (through the grate) and as secondary air

(via the airwash) and post-combustion (located in the back wall).

On the ambiente a5 the air adjustment lever should be moved upwards. The

lever is located on the rear of the stove.

Restricted air flow: Adjustment lever roughly in the middle position. The

primary air supply is now closed off, so that the fire is not supplied with

too much air. The secondary air flows over the ceramic glass pane via the

airwash and post-combustion, which minimises sooting-up of the glass.

This is the normal position during combustion. The exact position depends

on local conditions and can be adjusted by the operator according to how

the stove is burning.

Air supply closed: Adjustment lever at the far left. In this position, no com-

bustion air is supplied to the fire chamber of the ambiente a1/a2/a3/a4/

a4 H

O stove. Wait for all the fuel to burn away before closing off the air

supply. The air supply should always be closed when the stove is not in use.

On the ambiente a5 the air adjustment lever should be moved downwards.

The lever is located on the rear of the stove.

B Air supply restricted

C Air supply closed

4.3 LIGHTING UP / BURNING

Lighting your stove is very easy if you follow the instructions below:

1. The ambiente a1/a2/a3/a4/a4 H

O/a5/a7/a8 stove must not be operated

unless the fire chamber lining is correctly installed.

2. Switch off all extractor fans (kitchen, bathroom, toilet, etc.) That pre-

vents a partial vacuum occurring in the room where the stove is installed

and possible leakage of flue gases from the stove into the room. Check

the combustion air supply (open the flap if necessary).

3. Move the air adjustment lever to position A and open the firebox door

(refer to Fig. 16).

4. Build a pile of split kindling (soft wood is best) in the middle of the fire

chamber as shown.

5. Place some standard firelight-

ers underneath the pile to help light

the fire. (Paper is not recommended

as it burns away too quickly and

causes flying ash).

6. Never use spirit, lighter fuel,

oil or any other highly flammable

liquids.

7. Now light the fire by lighting the firelighters, and leave the firebox door

open about 3-5 cm. The fire should soon start burning strongly and

brightly.

8. Once the kindling is well alight you can add some small hardwood split

logs or larger softwood logs, piling them up on top.

9. Close the door once the logs are burning well. The air adjustment lever

remains in the far right position (air supply open) and it should stay in that

position for at least another 20-30 minutes to get the stove up to operating

temperature.

10. More information about how

much wood to put on the fire can be

found in section „4.3.2 Hourly Wood

Consumption“ on page 33.

11. Once all the wood has fully

burned away, leaving only embers

from the first logs put on the fire,

more wood can be added as required

(hardwood is ideal).

12. According to the weather conditions, move the air adjustment lever more

or less to the centre position, or a little

beyond the centre (Fig. 16). Judging

how far to move it depends on expe-

rience and current conditions at the

place of use.

13. Do not wrench the door open, as

if you do that there is a risk that a sudden

drop in pressure will allow flue gas to

escape into the living room. Open the door slowly to begin with, just a crack.

14. By waiting till the ember stage before adding more wood you avoid the

risk of smoke escaping when the door is opened.

15. Avoid the temptation to put more than the recommended amount of

wood on the fire.

16. If your chimney is drawing too strongly, the fire will blaze up even with

only a minimal secondary air supply. Move the air adjustment lever

slightly to find the best position for controlled combustion. The farther

you move the adjustment lever towards the ‘air supply closed’ position,

the less air is delivered to the fire chamber. Take care not to shut off the

air supply too much, thus starving the fire of air (refer to section „4.4

Controlling the Heat Output“ on page 33).

4.3.1 ADDING MORE WOOD / FIRE OUT

Wait for the wood in the firebox to burn down to embers before adding

more wood.

1. Move the air adjustment lever to the fully open position (Fig. 16).

2. Open the firebox door very slowly (use the protective glove) to avoid

turbulence which can encourage smoke to leak out.

3. Place split logs on top of the embers (bark uppermost, cut surface to

the side). Make sure the air supply is open. The embers must not be

starved of air.

4. Close the firebox door (use the protective glove).

5. If the new wood does not start to burn straight away, leave the air adjust-

ment lever in the lighting position (far right) for about 2 to 5 minutes.

Wait for all the new wood to catch light before altering the air adjust-

ment lever position again.

The fire goes out when all the wood has been burned away and there is

no possibility of the fire continuing to

smoulder or incomplete combustion.

The air adjustment lever can now be

closed. Always leave the air adjustment

lever in the closed position when the

stove is not in use (refer to Fig. 16).

4.3.2 HOURLY WOOD CONSUMPTION

To avoid damage from overheating, such as discolouration of the steel,

deformation, etc. and to keep your stove operating efficiently even after

years of use, it is essential to stoke the stove correctly. To avoid the risk of

overheating, do not exceed the maximum heat output.

Please refer to section „2.2. Technical Data“ on page 7 for the

recommended hourly wood consumption. The individual pieces of

wood should be about 25 cm in circumference.

Please note: Increasing the wood feed beyond this amount may result in

overheating and damage to the stove. Wood pellets (briquettes) have an

appreciably higher heat output than hardwood. Hourly consumption when

using pellets should therefore be at least 20% lower than when burning

logs: approx. 1.5 kg/h for the a1/a2/a3/a4 and approx. 1.7 kg/h for the

a4 H

O/a5/a7/a8.

The warranty will be voided in cases of damage due to overheating (exces-

sive hourly wood consumption).

4.4 CONTROLLING THE HEAT OUTPUT

The heat output is controlled via the amount of fuel placed in the stove. Do

not attempt to slow down combustion drastically by reducing the air supply.

When burning wood, the result is incomplete combustion and, thus, wasted

fuel and unnecessary environmental pollution, as wood gives off gases even

when smouldering. That also increases the soot deposits on the viewing

panes. What is more, there is the risk of deflagration (explosive ignition of

the flue gases). Always ensure that the firebox door is tightly closed to avoid

accelerating combustion by an uncontrolled air supply. Your stove’s output

also depends on the chimney draught. The draught may be affected by

factors like the cross-section of the chimney or weather conditions (strong

winds, etc.).

4.5 ROOM HEATING CAPACITY / ROOM TEMPERATURE

The room heating capacity was previously quoted according to DIN standard

18893 (last issued August 1987) and is thus no longer relevant to modern

post-1990 homes. However, the old room heating capacity value may still be

of interest as a comparative value or for use in the case of older structures

pre-dating the 1977 thermal insulation standard.

A nominal heat output of 5.0 kW for the a1/a2/a3/a4, 8.0 kW for the a4 H

7.0 kW for the a5 and 5.9 kW for the a7/a8 corresponds to the following

room heating capacity when operated as intermittent heating (i.e. with

breaks in operation of less than 8 hours):

***Considerably bigger rooms can be heated with modern thermal insulation.

Direct room heating not including water heating

A detailed explanation of ‘favourable’, ‘less favourable’ and ‘unfavourable’

can be found in DIN standard 18893. Simply put, ‘favourable’ describes a

situation where the room has only one external wall and otherwise mainly

adjoins heated internal rooms, whereas ‘unfavourable’ refers to a room with

two external walls and adjoining unheated rooms.

The values indicated above refer to structures pre-dating the 1977 ther-

mal insulation standard. They represent a simplification which is valid for

room sizes up to 200 m³. DIN 18893 standard recommended a calcula-

tion according to DIN 4701 for rooms larger than 200 m³. Nowadays, an

estimate according to TR-OL is preferable or, in particular, the calculation

should be based on DIN 12831.

4.6 HEATING IN THE TRANSITIONAL PERIOD / UNFAVOURABLE WEATHER CONDITIONS

In the transitional period, when the outside temperature is above approx.

15°C, or during unfavourable weather conditions (down winds, etc.), disrup-

tion to the chimney draught may occur due to sudden rises in temperature,

with the result that the flue gases are not completely extracted. In these

circumstances a smaller amount of fuel should be placed in the stove and

the air adjustment lever should be moved to the maximum position (refer

to section „4.2 Controlling the Combustion Air Supply“ on page 30, Fig.

16). The fuel in the stove will then burn away faster (with more flames). This

will help to stabilise the chimney draught. To avoid resistance in the firebed,

it should be carefully raked at frequent intervals to remove the ash. The air

supply can be reduced slightly (middle position) when the chimney draught

has stabilised.

4.7 OPERATION OF THE WATER HEAT EXCHANGER WITH THE ambiente a4 H

The firebox door should only be operated in

mode A1. Tampering with the closing system

is not permissible.

The water heat exchanger is operated via

the lever behind the stove at the right-hand

side (cf. Fig. 11). This switches between the

lighting-up/adding more fuel position and the

combustion position. The lever does not have

an intermediate position.

A Flue gas routed via water heat exchanger B Flue gas not routed via water heat

exchanger

Combustion position (Fig. 17 A) The lever is right at the top. All the flue gas

will now be routed via the ambiente a4 H

O’s water heat exchanger. Wait for

the stove to heat up fully, the fuel to catch light and embers to form before

moving the lever to this position. That normally takes about 15-20 minutes.

Lighting or fresh fuel phase (Fig. 17 B) The lever is right at the bottom.

The flue gas bypasses the ambiente a4 H

O’s heat exchanger. That allows the

chimney draught to develop as quickly and effectively as possible.

To keep the ambiente a4H

O operating efficiently, be sure to add wood in time

to prevent the flue gas temperature dropping too low.

5. FUEL

The foundation “Wald in Not” (Forest in Danger) put it aptly in one of their

information brochures: “Wood does not cause any burden for nature. Wood

is stored energy from the sun. Sunlight, water and carbon dioxide are the

building blocks from which wood is created. Sunlight is chemically bonded

during the whole life of the tree. The sun’s energy is stored in lignin and

cellulose. This energy is set free again when the wood is burnt! You can find

out more information on the internet site www.wald-in-not.de.

Fireplaces may only be operated using fuels that correspond to the 1st

BlmSchV regulations. Only firewood (recommended residual moisture 20%

or less) or wood briquettes according to DIN 51731 are permissible for use

in stoves.

Incidentally: A measuring device for determining the moisture of firewood

does not cost very much and quickly pays off.

No other type of fuel may be used!

Therefore, it is not permissible to burn the following:

• Varnished or plastic-coated wood

• Chipboard or wood that has been treated with wood preservatives

• Wood originating from Europool palettes

• Waste, household rubbish and old clothes

• Paper, paper briquettes, cardboard

• Damp wood (residual moisture over 20%)

• Plastics / foam material of any sort

• Solid or liquid materials damaging to wood

Fig. 17

It is prohibited to burn these and other unsuitable materials in your stove.

If materials other than the approved fuels of firewood or wood briquettes

according to DIN 51713 are burnt, this can lead to the formation of dan-

gerous gasses and disruption to the burning process right through to

deflagration.

The guarantee is rendered void if the ambiente a1/a2/a3/a4/a4 H

O/a5/a7/

a8 stove is operated using non-approved fuels.

Use small pieces of wood to get the fire going. Only used chopped wood as

a fuel that is no thicker than approx. 8 cm at its thickest point. The optimal

length of the wood is approx. 25 cm. Do not add too much wood to the fire;

it is preferable to add small volumes of wood. When adding wood to the fire,

the embers must not be completely covered.

5.1 CO2 NEUTRALITY

Wood only releases as much carbon dioxide as it collected and trapped from

the air as a tree. It is irrelevant in this case whether the wood is burned or

rots in the forest – the carbon dioxide released always remains the same.

New trees absorb the carbon dioxide that is released from the wood during

burning – a closed natural carbon dioxide cycle is produced.

Conclusion: Nature remains in a state of equilibrium as a result of burning

wood. Germany has regulated the sustainable management of forests by

law. This obligation has led to a growth in the volume of wood because

the increase in wood grown in forests is on average 40% greater than the

volume of firewood and timber used.

5.1.1 STORING WOOD

In general, it is recommended to store firewood for approx. 2-3 years, the

wood should be protected from dampness and well ventilated (e.g. under a

roof overhang on a side of the building protected from the weather). Wood with

moisture content < 20% will be achieved significantly quicker with optimal

storage. Therefore, you should store your firewood already chopped because

the bark can prevent the moisture escaping from the wood. You should leave

a distance the width of a hand between the logs for good ventilation so that

the air can circulate properly and the moisture escaping from the wood can

be taken away by the air. A distance to the floor of approx. 20-30 cm should

be maintained underneath the stack of wood. Renewed absorption of moisture

due to precipitation (e.g. rain or snow) should be avoided. Storing wood in

garages, under plastic sheets or in poorly ventilated cellars is not recom-

mended because the moisture present in the wood cannot escape properly.

Use an easily obtainable wood moisture measuring device to check your fuel.

5.2 YOUR CONTRIBUTION TO ENVIRONMENTAL PROTECTION

Whether your a1/a2/a3/a4/a4 H2O/a5/a7/a8 stove burns in an environmen-

tally friendly way is dependent to a large degree on how it is operated and

which fuel is used. The following advice should help you to operate your

stove in an environmentally friendly way:

• As far as possible, do not use any resinous wood (spruce, pine, fir).

These types of wood cause sooting of the stove panel to occur quicker

and there is an increase in flying sparks. Therefore, please only use

hardwoods (birch, beech, oak, wood from fruit trees) for safety reasons.

• Adjust the volume of wood used to the relevant heating requirements.

• We recommend purchasing a wood moisture measuring device.

You can check whether a clean and low-emission burning process is

taking place in your stove as follows:

• The ash should be white. A darker colour indicates residual charcoal and

incomplete burning.

• The exhaust gases from the chimney pot should be as clear as possible

after the lighting phase (the clearer the exhaust gases, the better the

burning process).

• The firebox lining in your stove should be light and not sooted after

burning.

Note: The fireplace may not be used as a waste incinerator! Further-

more, this stove is designed for temporary burning. Permanent oper-

ation can also not be achieved due to the extraction of combustion

air and is not permitted!

6. CLEANING AND CARE

The stove may only be cleaned in a cold state. Please note that cleaning can

lead to soiling of the installation room and your clothing. We recommend

that you protect the area around the opening to the fireplace from soiling

with a plastic sheet or a blanket and that you wear work clothes. All disman-

tled components must be installed again after cleaning.

6.1 CLEANING THE FIREBOX / OUTER CASING

• The stove, the firebox, the smoke collection chamber with the exhaust

gas control system, the combustion air system and the connecting flue

pipes to the chimney must be inspected for deposits and, if necessary,

cleaned at regular intervals on a yearly basis and also perhaps during

and after the heating season and after the chimney has been cleaned

(consult your stove dealer or chimney sweep in your district). Remove

any deposits using a hand brush and/or an ash vacuum cleaner (special-

ist dealer).The chimney is to be cleaned by a chimney sweep at regular

intervals! Furthermore, the stove should be inspected each year by a

specialist.

• Exhaust gas control system: An additional exhaust gas deflector can be

found above the fireplace and in the exhaust gas collection chamber.

These components should be cleaned regularly. The exhaust gas deflec-

tors can be removed in order to complete this task. They need to be

lifted, then tilted and can be removed through the firebox. The deposits

on the deflectors can be cleaned off easily using a hand brush.

• Ash removal: Your ambiente a1/a2/a3/a4/a4 H

O/a5/a7/a8 stove is

suitable for burning dry wood, which burns best in its own ash. If you

nevertheless want to remove the ash from the firebox, open the stove

door. Lift the grate out of the firebox and brush (using a standard fire-

place tool set) the ash into the ash tray located below. The ash tray can

be removed in an upwards direction in order to dispose of the contents

in the correct manner.

ambiente a5

If you want to remove the ash from the fire chamber, open the stove door

and swing open the stove cover panel below the door. Lift the grate out of

the fire chamber and brush off the ash (using an ordinary fireside compan-

ion set) into the ash pan underneath. Remove the ash pan and dispose of

the contents properly.

• Please note that the embers can still be burning up to 24 hours later or

even longer!

• Cleaning the ceramic glass panel: The glass panel can be easily cleaned

using standard fireplace glass cleaner, which you can also obtain from

your specialist dealer. Finally, wipe the glass panel with a dry cloth (do

not smudge on the glass panel!). The glass fibre seals should not be

soaked with cleaning fluids!

• Varnished surfaces and the outer casing can be cleaned using a damp

cloth (do not use a microfiber cloth!).

• Glass surfaces can be cleaned using a standard glass cleaner and a soft

cloth (do not use a microfiber cloth!).

• Stainless steel surfaces can be cleaned using a standard stainless steel

cleaner. This is only to be applied in the direction of the finish!

• Natural stone surfaces can be cleaned with a damp cloth or correspond-

ing standard cleaner!

• Ceramic surfaces can be cleaned with a damp cloth or corresponding

standard cleaner!

Regularly remove dust from above and below the stove during the heating

season because the dust particles may burn or char. This can lead to soiling

of the installation room and the furniture within.

6.1.1 CLEANING THE WATER HEAT EXCHANGER IN

THE ambiente a4 H

Cleaning the water heat exchanger is essential. The stove can achieve its full

effectiveness when it is regularly and properly maintained/cleaned. As a general

rule, cleaning is to be carried out in a cooled-down state!

Because the water heat exchanger directly cools the exhaust gasses from the

ambiente a4 H

O and this inevitably leads to deposits forming on the water heat

exchanger, it is necessary to regularly clean it using the integrated cleaning

system. The cleaning process should be carried out weekly to avoid the cleaning

mechanism become locked in place (caused by e.g. condensation/sooting due

to non-functioning fittings or missing components etc.). A visual inspection of

the cleaning mechanism should be carried out every 4 weeks.

The frequency of the cleaning is also dependent on a variety of factors

(intensity of use, length of fire, fuel, “drawing” performance of chimney,

etc.) and it is not possible to

give general cleaning intervals. If

no significant deposits etc have

occurred after the first week of use

then the cleaning intervals can be

extended a little.

Cleaning process:

The operating handle is included

in the delivery of the stove and

should be inserted into the 20 mm

hole on the upper left side of the

stove for cleaning purposes. Once

Fig. 18

inserted, the handle should be turned approx. 5 times to the right and to

the left until the limit stops (approx. 20° rotation angle). When inserting the

operating handle, it is important to ensure that the handle does not knock

against the painted/varnished edges of the stove.

The soot released during the cleaning process automatically falls onto the

deflector plate in the firebox and should be cleaned out at least 2 x per

season.

6.2 FIREBOX LINING

During the warming-up phase it is normal for the lining to be covered by a

dark coating. Once the operating temperature is reached this layer on the

firebox lining will have burnt off. Cracks are not considered grounds for a

justified complaint. The lining is subject to very high stresses. An expansion

or contraction crack is not serious and is not a functional defect. However,

any parts of the fire chamber lining that are broken and have moved out of

position need to be replaced. If replacement fireclay is required, this can be

ordered from your heating contractor under the appropriate order number,

stating your stove model (refer to Figs. 19-22).

6.3 CHIMNEY FIRE

When burning wood (especially softwood), sparks can often be transferred

from the fireplace to the chimney. These sparks can set light to the layer of

soot in the chimney (this only occurs rarely if the chimney has been regu-

larly cleaned by a chimney sweep). The chimney will then burn. This can be

recognised by flames blazing out of the chimney outlet, heavy flying sparks,

smoke and odours or an increasingly hot chimney stack. It is important in

these cases to handle the situation correctly. The fire brigade should be

notified via the relevant emergency number. In addition, a chimney sweep

ambiente a7 Fig. 21

ambiente a8 Fig. 22

should be informed about the situation. Combustible objects should be

moved away from the chimney.

Warning from experts: Do not attempt to put out the fire with water while

waiting. The temperatures in a chimney fire can reach up to 1300 °C. The

extinguishing water will immediately turn to steam. A 10 litre bucket of

water results in 17 m

of steam. The enormous pressure that results can

break the chimney apart.

Once the chimney fire has burnt itself out, the chimney must be examined

by a specialist for cracks or leakages and, if required, repaired accordingly.

6.4 MAINTENANCE

The door seal must be checked on a regular basis. If necessary, this seal is

to be replaced (due to wear, breakage etc.).

The firebox lining must be checked at regular intervals. It consists of natural

products that are subject to expansion and contraction during every heating

process. Cracks can occur as a result. As long as the firebox lining retains

its position in the fireplace and doesn’t break, it remains fully functional.

A yearly service of the stove carried out by a specialist is indispensible to

ensure fault-free functionality (where possible, before the heating season)!

The fireplace may not be modified!

Only original replacement parts that have been approved by the manufac-

turer may be used! Please contact your specialist dealer should you require

any parts!

6.4.1. MAINTENANCE OF THE WATER HEAT EXCHANGER IN THE ambiente a4 H

Carrying out maintenance on the ambiente a4 H2O is essential. The ambiente

a4 H

O can only achieve its full effectiveness when it is regularly and prop-

erly maintained. A technical heating inspection of all safety devices (thermal

discharge safety device, etc.) is required each year before the heating

season. This inspection may only be carried out by a specialist company.

We recommend that you agree a service contract with your specialist

company. This ensures that the yearly safety inspections will be reliably

carried out before the heating season. All yearly safety inspections are to

be documented!

6.4.2 BLEEDING AIR OUT OF THE WATER HEAT

EXCHANGER IN THE ambiente a4 H

The bleeding process is carried out in the area of the heating connections

in the lower compartment. The bleeding vent is opened using the bleeding

key. A suitable collection container or a large cloth should be kept ready

to collect any escaping water. A small hose can also be attached to the

bleeding vent. Once the vent has been opened, water will initially escape

from the bleed hose and then air will follow after a few seconds. After the

air has escaped through the vent, it should be kept fully open for a further

five seconds.

The system should be bled:

• Before and during the first use of the stove.

• Daily for the following weeks until no more air escapes.

• When noises (air bubbles) can be heard in the heat exchanger.

• When the pressure of the home water provision is adjusted.

7. TROUBLESHOOTING

You can rectify the following problems with your ambiente a1/a2/a3/a4/

a4 H

O/a5/a7/a8 independently, please contact your stove builder or fitter

for all other problems.

7.1 GLASS EXPERIENCING HEAVY, QUICK AND IRREGULAR SOOTING

If this did not occur from the very beginning, please check the following points:

• Are the correct fuel and technology being used?

• Is the combustion air control fully opened? (control lever turned fully to

the left)?

• Is the external combustion air flue unblocked?

• Does the sooting occur within half an hour? (gradual soiling during oper-

ation of the system is normal. A car windscreen will also become soiled

during a journey!) To resolve the problem, ensure that no pieces of wood

are in direct contact with the glass panel or in very close proximity to it.

• Is the firebox insulation a perfect fit?

• Is the wood dry enough?

• Has enough wood been added to the fire? (when the volume of wood is

too low, an insufficiently high temperature is achieved in the fireplace)

7.2 FIRE IS DIFFICULT TO LIGHT

If this did not occur from the very beginning, please check the following points:

• Are the correct fuel and technology being used?

• Is the wood dry enough?

• Is the wood too thick?

• Has the air intake been sufficiently guaranteed?

• Are you in the transitional period?

• Are you experiencing atmospheric inversion?

• Is the combustion air control fully opened?

• Is the external combustion air flue unblocked?

7.3 SMOKE LEAKAGE WHEN ADDING WOOD TO THE FIRE

If this did not occur from the very beginning, please check the following

points:

• See all questions in Point 7.1

• Has the burnt-through phase been reached?

• Is the bypass valve open?

• Has the required low pressure been achieved?

• Is the chimney unblocked?

• Has your stove already reached its operating temperature?

• Did you open the door slowly at the beginning?

7.4 FIRE BURNS TOO QUICKLY / WOOD CONSUMPTION TOO HIGH

If this did not occur from the very beginning, please check the following points:

• Has the wood been cut to a sufficient size?

• Is the chimney drawing air too strongly?

• Have your reduced the combustion air control (control lever turned fully

to the left)?

• Are you using solid hardwood with 15-18 % residual moisture?

• Is the door completely closed?

• Have you kept to the recommended volume of wood?

7.5 WATER HEAT EXCHANGER IN THE ambiente a4 H2O

Description of problem Cause / Solution

Thermal discharge safety device is constantly being triggered (constant discharge of water through the discharge valve). The water heat exchanger cannot pass on heat to the heating system.

• The accumulator tank is “full”.

•

Attention: Extract heat from the accumulator tank.

• Check the functionality and settings of the pump thermostat and the load unit (heat charger).

• Set the pump setting one level higher (larger flow rate).

• Circulation pump is not running. Is the electricity connection defect?

• Bleed air from the stove.

• Check the system pressure.

Water escapes onto the floor area of the stove during the first few uses.

• Insofar as the stove and the heating installation have been subjected to a pressure test after the installation, the escaping water is condensation from the fuel and the firebox lining. If more than

0.2 litres of water accumulates then the heating system pressure needs to be tested.

Gurgling noises in the water heat exchanger. Air in the system.

• Check the system pressure.

• Bleed the air from the system at the vent. In newly filled or topped up systems, it can take some time until all of the air has collected. Bleeding the air out of the system once is often not sufficient.

Thermal discharge safety device is dripping.

• Rinse out the thermal discharge safety device by pressing the red button on the fitting.

• Check the fitting of the connection seals and the pistons (see instructions for thermal discharge safety device).

• If required, integrate a filter into the system before the thermal discharge safety device (observe the minimum flow rate!)

Radiators are not heating up. Radiators that are not located in the installation room are cold.

• Radiator thermostats close when the set room temperature is achieved. The convection heat from the fireplace is being distributed into connecting rooms.

• The heating system is sluggish depending on the configuration. It takes a little time until the heating system passes on the heat.

• Hydraulically balance the heating system.

• Check the functionality of the heat circulation pump.

• Increase the amount of fuel used.

Description of problem Cause / Solution

Greater and quicker soiling of the firebox lining and the ceramic glass panel. The firebox lining no longer burns free any soiling. Fire can only be lit with difficulty

• Remove deposits in the heat exchanger and in the connecting flue pipes to the chimney.

• Check the correct functionality of the pump thermostat

• Ensure correct burning, wood feed quantities, wood moisture content < 20%

• Correct the position of the air control lever

• Check the correct functionality of the load unit (heat charger).

Quick soiling of the exhaust gas flues in the water heat exchanger. Inadequate burning performance.

• Check the load unit (heat charger).

• Ensure correct burning, wood feed quantities, wood moisture content < 20%

• Remove deposits in the heat exchanger and in the connecting flue pipes to the chimney.

• Check the correct functionality of the pump thermostat
