1. General information
Before assembling and installing the H
2O fireplace insert 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 fireplace insert. The chimney calculation is based on DIN EN 13384 using the value specifications table contained in this manual (see Specification 1.2)
(DECLARATION OF PERFORMANCE MAY BE VIEWED AND IS AVAILABLE FROM WWW.SPARTHERM.COM)
Young children, the elderly and the frail, and pets: as with all heating
devices, a guard should be fitted to protect the above because both the glass door and the fireplace covering can become very hot.
Risk of burns!
Never leave a fireplace unsupervised when the fire is burning or when it
has just gone out. Do not leave the fireplace unattended for prolonged periods of time.
CAUTION:
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 fireplace insert 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 regulations, and in particular, in Germany, the relevant Heating Regulation (FeuVO) of the state where you live.
To make better utilisation of the high flue gas temperatures, a water heat exchanger is integrated in the linings and in the flue gas collector. A hot water storage tank or buffer storage tank, etc., can be heated with the hot water generated. If these or similar system components are not available then other structural measures must be taken to ensure safe, constant heat dissipation.
Generally speaking, the fireplace must be used with a door that closes automatically. No modifications to the closing device are permitted. No additional heat exchangers, supplementary heating surfaces, etc, which
- 6 -
extract heat from the flue gas, may be incorporated into the connecting pipe to the chimney. The H
2O fireplace insert is intended as an auxiliary heat generator for
water heating systems in accordance with DIN EN 12828, since the nominal heat output is only maintained as long as the fireplace insert is stoked to its nominal heat output. The fireplace may only be used with suitable combustion control systems adjusted as appropriate. Please consult Spartherm Feuerungstechnik GmbH as necessary.
Never use the H
2O fireplace insert without water.

2. Installation
Generally speaking, the water-heating components and the requisite safety devices, etc., must be installed by a specialist company. The H
2O fireplace insert must be installed in such a manner that all the
components, including those behind the fireplace lining, are accessible and available for inspection at all times. After erection and connection of all services, and before mounting the heat chamber, the fireplace insert and associated heating installations must be checked for leaks by means of a pressure test.
For this purpose the H
2O fireplace insert must be aligned horizontally by
adjusting the height of the fireplace insert feet, or provided with a slight upward gradient to the bleed plug at the front.
The H
2O fireplace insert must be installed in accordance with the
installation manual for fireplace inserts.
2.1. Basic installation requirements
The H
2O fireplace insert may only be installed in thermostatically
protected systems in accordance with DIN 4751 or DIN EN 12828. All connections to the heating system must, generally speaking, allow of being detached (e.g. in the form of a threaded connection). Only tempera­ture-resistant pipes may be used inside the fireplace lining. When sealing materials are used, you must ensure that they are sufficiently resistant to the temperatures involved. Because of the position of the feed connection and the temperature sensors in the front area of the fireplace insert, an opening must be provided in the front of the heat chamber.
All safety devices must be installed in the “cold” area, or outside of the fireplace cover. The temperature resistance of the safety devices is not generally sufficient to allow their installation inside the fireplace cover.
All water-carrying components must be protected against frost.
During installation, always follow the installation and operating manuals for any additional components fitted.
- 23 -
No claim is made as to the completeness of this list of regulations.
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 the fireplace is installed must be of such a type and size that the fireplace can be correctly operated.
During installation, connection and operation of the H
2O fireplace insert,
always follow and apply all the requisite national and European standards and local regulations (DIN, DIN EN, regional building regulations, German state heating regulations, etc.).

2.2. Electrical connection
Full electrical installation of the individual components of the heating system may only be carried out by an authorised specialist company. All the work must be carried out according to the VDE Regulations (e.g. VDE 0105, VDE 0116, VDE 0100 etc.) and the technical connection require­ments of the local power supply company.
2.3. H2O fireplace insert connections
The connections for the safety heat exchanger, the return and the rear bleed valve are located on the rear and can always be accessed through an inspection opening (see Fig. 2a-2f) via the combustion chamber. The connections for the feed, the front bleed valve and the immersion sleeves for the temperature sensors are all located at the side on the flue gas collector (see Fig. Fig. 2a-2f).
These require an opening to be provided in the fireplace cover to obtain access. For transport purposes the connections are provided with transport protection devices, which must be removed during installation. The connections are clearly marked and must not be used for any other purpose. Equally, the integrated safety device (safety heat exchanger) must not be used for heating water. We recommend the use of straight or angled radiator screw connections for the pipe connections. If the protective anode (only Varia H2O XL and XXL) is installed in open heating systems, make sure it is accessible so that it can be easily replaced. The length of the anode must not exceed 30 cm (folding insert) from the first thread.
When installing the Varia Ah H
2O / A-FDh H2O in an existing heating
system we recommend a minimum nominal pipe width for heating pipes of: copper pipe, min. 28 x1.0 mm or steel pipe, min. 1” (DN25, 33.7 x
3.25 mm). Plastic pipes or composite pipes must not be used inside the heat chamber. If ‘temperature-resistant’ gaskets (>140°C) are used on metal pipes (press systems), these pipes must not be fitted within the radiant area of components carrying flue gas (distance of 200 mm). As a general rule, though, after dimensioning they should be connected up by a specialist company.

Generally speaking, the Technical Rules of the Tiled Oven and Air Heating Building Trade (TR-OL 2006) must be followed.
2.5. Bleeding
Two bleed valves are available for bleeding the water heat exchanger. For the Varia 1V/1Vh H
2O, only one bleed valve is provided, on the upper heat
exchanger, and on the Varia Ah H
2O and Varia A-FDh H2O the bleed
valve is located at the top left and right. Firstly, the upper bleed valve (in the area of the flue gas collector) can be used. This requires that a sufficiently large opening be provided in the lining in the immediate vicinity. Secondly, the lower bleed valve (in the area of the connections on the rear) can be accessed through the inspection opening in the combus­tion chamber and this can be used. After commissioning, the insert must be bled several times because the heating water emits gases due to the high temperatures.
For the Varia 1V H
2O, a vent pipe fitted to the rear wall is available (see
Fig. 3).
- 33 -
For this version the following additional information must be borne in mind when performing installation.
The TROL guidelines regarding the free cross­section of the vent openings and the maximum supply air temperatures of 75°C must always be followed. Lockable circulating and supply air openings are not recommended. This is to ensure that no heat accumulates inside the heating chamber. (Fig. 3)
If the vent pipe has been dismantled on the installa­tion site to transport it, for example, make sure that for subsequent assembly the copper pipe in the lower area rests fully against the copper rail and the body. The tightness of the screw connection on the head section and correct seating of the heat insulation must then be checked.

2.6. Safety valve
A component-tested safety valve (e.g., Syr type 1915), with a maximum response overpressure of 3.0 bar must be installed in the feed pipe in the immediate vicinity of the H
2O fireplace insert. During installation,
attention must be paid to the manufacturer’s specifications (including ambient temperature) for the safety valve. A shutoff device must not be incorporated in the system between the safety valve and the H
2O fireplace
insert as it could prevent the safety device from operating. Furthermore, all the required safety devices must be integrated throughout the system in such a manner as to ensure non-hazardous operation. A separate safety valve must still be fitted, even if there is one elsewhere in the system (make sure you comply with TRD 721).
2.7. Load unit
Generally speaking, the H
2O fireplace insert may only be operated with a
suitable load unit. During operation the return temperature must be at least 55°C. On the Varia Ah H
2O and Varia A-FDh H2O the return
temperature must be at least 60°C. To ensure this temperature is achieved, a circulating pump must be installed in such a manner that it does not cut in until a water temperature of 60-65°C has been reached in the heat exchanger. This must be implemented using the pump thermostat (supplied, e.g., JUMO heatTHERM or Afriso) (see section 3.9).
To avoid dropping below local dew points and resulting deposits on the water heat exchanger, a regulated load unit must generally be installed. The longer the pipe run between the load unit and the fireplace insert, the longer the temperature in the fireplace insert remains below the dew point, as the heating water first has to be heated when the system is fired up. We therefore recommend fitting the load unit in the immediate vicinity of the fireplace insert, ensuring it is readily accessible.
Please note: If there is no load unit fitted or it is not operating properly,
we cannot accept claims under warranty or general liabil­ity for operating faults or corrosion damage (soot build­up, deposits, etc.) on the water heat exchanger or on the chimney, etc.

2.8. Overheat discharge valve
Since the heating for the H
2O fireplace insert is not automatic and cannot
be quickly switched off, the hot water attachment must be equipped with an overheat discharge valve in accordance with DIN 4751 – Part 2 or DIN EN 12828 to prevent hazardous situations in the event of a fault, e.g., a power failure. A safety device is installed for this purpose in the H
2O
fireplace insert (safety heat exchanger) to protect against overheating. This safety device must not be used as a water heater.
The overheat discharge valve supplied (e.g., SYR, type 3065) is tested and approved for a minimum water flow rate of 900 kg/h. The sensor on the capillary tubing must be inserted and permanently fixed in the connection opening of the H
2O fireplace insert (in the sealed-in immersion
sleeve) that is marked accordingly.
The following points must always be observed during installation to ensure the safety device can work properly:
During installation the enclosed installation and operating manual
supplied by the overheat discharge valve manufacturer must be fol­lowed!
The fittings of the overheat discharge valve may only be installed in
the feed pipe. This is to ensure that there is no standing water in the safety heat exchanger when used as intended.
The fittings of the overheat discharge valve must not be sited in the
hot area of the heat chamber (convection chamber) of the fireplace system (max. ambient temperature 80°C). Select the position on the basis of the length of the capillary tubing.
A minimum flow pressure of 2.0 bar must be available at the cold
water intake. This pressure must be maintained at all times. Fluctua­tions in water system pressure must not occur. This means, for ex­ample, that supply from a domestic water system that is itself de­pendent on the mains supply is not permitted.
A minimum water flow rate of approx. 900 kg/h must be ensured. It
must not be possible to shut off this supply pipe.
The heating insert must be aligned so that the front bleed valve is at
the highest point.
All safety-relevant components must be integrated in the system in such a manner that checks may be carried out on their operation and for possible leaks at any time. The discharge of the overheat discharge valve must be executed in such a manner that a test may be carried out at any time (e.g. via an outlet with siphon).
- 36 -
2.9. Thermal pump control system
The fireplace insert must always be used with a load unit. A JUMO or Afriso thermostat switch is also supplied with the cell. This must be electrically integrated into the power supply of the load unit (circulating pump). The appropriate rolled-up capillary tube should be unrolled and inserted into the marked immersion sleeve at the top front right/left and secured with the clip supplied. Ensure there are no kinks in the capillary tube! This switch ensures that the circulating pump only cuts in if the water temperature is adequate and is switched off again if the temperature drops below the specified level. The connection is made as shown in Fig. 4a-b. Control of the circulating pump by means of a boiler control system or similar device is not recommended. During installation the enclosed installation and operating manual for the thermostat must be followed. The thermostat sensor must be inserted and permanently fixed in the connection opening of the H
2O fireplace insert (sealed immersion sleeve)
that is marked accordingly.
The maximum loading capacity of the thermal pump control system is approx. 500 W at 230 V AC. The factory setting of the minimum thermostat can be adjusted by means of the control dial and has been preset to a range of approx. 62°C to approx. 72°C. The start-up temperature of the pump is set on this thermostat. Optionally, if conditions so warrant, the setting range can be adjusted by the company performing installation. If the control dial is removed, the setting range can be varied by moving the locking disc, which can be reseated in a different position by removing the screws. In the minimum setting (the locking disc is fastened through the holes marked “min”), the setting range can be adjusted from approx. 57°C to approx. 67°C. Please note: The minimum setting of approx. 57°C may result in values below the dew point. The maximum setting (locking disc fastened through the holes marked “max.”) ranges from 67°C to 77°C.
The JUMO heatTHERM fittings must not be sited in the hot area of the heat chamber (convection chamber) of the fireplace (max. ambient temperature 80°C). Select the position in the cold area on the basis of the capillary tubing length!

2.10. Incorporation into a heating system
Please note: The H
2O fireplace insert may only be installed in a complete
system after detailed planning for the entire heating system according to relevant best industry practice and safety standards. The correct dimensioning of the pumps, fittings, pipework, buffer storage tank and safety components, such as the safety valve and expansion vessel, is the responsibility of the design office and/or of the company carrying out installation. Note that very high water outputs of approx. 20 kW can occur briefly during the combustion phase. The heating system should be dimensioned to take account of this.
The following calculation example may be helpful for dimensioning the buffer storage tank:


For the Mini Z1 H2O:
The following assumptions were made in this case:
Buffer storage tank size: 300 litres (approx. 300 kg of water) Water temperature in the storage tank initially: 30°C Final water temperature in the storage tank: 60°C Temperature difference 30°C (equivalent to 30 K) No heat extracted from the storage tank during heating by the Mini
Z1 H
2O, and no heat losses from the system
This means that a theoretical heat quantity of 37,683 kJ (= 37,683 kWs) is required to heat 300 litres of water in a storage tank from an assumed 30°C to 60°C (without accounting for any losses or heat extraction from the system). This heat quantity is equivalent to approx. 10.5 kWh. However, if the heating system is suitably constructed, e.g., in the form of a stratified storage tank, heat utilisation can commence shortly after circulation starts in the Mini Z1 H
2O. In such a case, only the excess
energy not required for heating is stored in the buffer storage tank.
Assuming, on average, output of approx. 5.5 kW from the H
2O fireplace
insert, heating of the entire storage tank takes just under 2 hours.
On very cold winter days the fireplace system may be in operation for as much as 12 hours or so. The thermal energy produced in such a case is then theoretically equivalent to 66 kWh. This thermal energy would then be sufficient to heat just under 1,900 litres of water (from 30°C to 60°C). However, heat is generally always extracted in such a situation so that there should be no overloading of the buffer storage tank (> 90°C).

2.11. Chimney connection / connecting piece
The H
2O fireplace insert is connected to the chimney by means of
connecting pieces of sheet steel approx. 2 mm thick. These must conform to DIN 1298 or DIN EN 28160 or the country-specific regulations regarding the chimney/flue gas system. Care must be taken to ensure that the flue gas pipe is laid over the shortest distance, rising to the chimney. As far as possible, the flue gas pipe should not involve any bends or detours around objects in its path. Furthermore, the flue gas pipe must be connected to a bricked-in wall lining on the chimney and sealed. If necessary, the flue gas pipe must be secured with clamps to ensure adequate fixing. The connecting pieces must be sealed as necessary. If the flue gas pipe runs through components made of combustible materials, the flue gas pipe must be insulated in accordance with the relevant regulations. Generally speaking, the connecting pipe must be installed in such a manner that it may be cleaned at any time. This must be ensured by providing a suitable number of cleaning openings. A measuring connection must be provided in an accessible position to allow the chimney ventilating pressure in the connecting pipe to be checked.
2.12. Height limitation / door stop
Only in the case of the Varia 2Lh/2Rh H
2O is the vertical sliding door fitted
with a variable door stop. This is factory set to the middle position, i.e. the opening height is reduced by 50 mm.
If the opening height is to be further reduced (reduction in opening height by 100 mm) or increased (maximum opening), the stops on both sides of the door must be converted. These can also be reached through the gap between the glass and door cover after completion of the heating chamber. The procedure for this involves the following steps:
Resetting the stop to maximum opening
1. Close the vertical sliding door so that the fixing screws can be reached (see Fig. 6)
2. Unscrew the M5x10 threaded screws on both sides of the unit using a 4 mm Allen key (spherical head). Fig. 7 view: from below, between glass and door cover.
- 54 -
3. Pull off the door stops in the direc­tion of the red ar­row. The stop may have become slightly stuck and will have to be “levered off” from below with a flat screwdriver.
4. The door stops are then no longer required but should be saved.
Resetting the stop to a 100 mm reduced opening height
This setting can be used if the flue gas system is not suitable for open operation when adding fuel. The air mass flow is reduced by reducing the opening height of the door.
1. Close the vertical sliding door so that the fixing screws can be reached.
2. Unscrew the M5x10 threaded screws on both sides of the unit with a 4 mm Allen key (spherical head).
3. Pull off the door stop in the direction of the red arrow. The stop may have become slightly stuck and will have to be levered off from below with a flat screwdriver.
4. Insert the door stop with the long lug facing the front of the unit. N.B. The door stops must not be swapped over by mistake.

3. Initial commissioning
Heat generating systems may only be erected and installed by specialist companies. Initial commissioning may only be carried out by an expert from the installation company. A certificate confirming proper installation and correct adjustment/operation of all the control and safety components must be submitted to the owner/operator of the system.
Initial commissioning may not be carried out until all the requisite components have been connected up, all the requisite safety devices integrated and made serviceable, the water heat exchanger flushed, filled, and the system bled. Operation without water, only partially filled, or with safety devices that are not serviceable, is not permit­ted.
On the first four occasions the fire is lit, it must be stoked with a maximum of 2.0 kg/hour of dry, thin wood (maximum circumference 25 cm). As a result the fireplace insert, the fireclay and the vermiculite are
slowly tempered, and the moisture from any storage, transport, etc., slowly evaporated off. If this is not done, the area between the glass panes may be contaminated and the fireclay crack. Please note: condensate may appear underneath the fireplace insert. This does not indicate a leak.
Moreover, the operator must be instructed in detail in how to use the entire system, as well as its operation and maintenance, including all supplementary components. Furthermore, the operator must be informed of the measures required to maintain safe operation of the system. Once
the induction has been carried out this must be documented in the commissioning log.
The installation and operating manual must always be retained and stored in an easily accessible place near the H
2O fireplace insert. Further
instructions on operating the H2O fireplace insert are given in the enclosed operating manual for Spartherm fireplace inserts.
The H
2O fireplace insert/heating systems must be filled and bled before
being lit. The heating system pressure must be checked (~ 1.5 bar) at the same time. Bleeding must be carried out daily after commissioning. As soon as no further air is present the interval can be extended.
- 57 -
Risk of oxygen corrosion:
Constant presence of air in the fireplace insert is due to a leak in the customer’s upstream pipework or incorrect positioning/dimensioning of the expansion vessel (diaphragm expansion vessel).
4. Operation
For operation, please refer also to the notes in the operating manual for our fireplace insert. The notes in this installation and operating manual relate to specific operation of a fireplace insert with integrated water heat exchanger.
Generally speaking, the combustion chamber door must be used
as a door that closes automatically. The door may only be opened to add firewood or, when cold, for cleaning. Tampering with the closing device is not permitted.
CAUTION: 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!
There must be at least 80 cm between combustible compo-
nents/furniture and the glass!
The fireplace insert is designed for burning dry, natural firewood
with the bark still on, as well as wood briquettes. No other fuels may be used.
Operation partially fuelled will result in low flue gas temperatures.
This may lead to chimney damage if the H
2O fireplace insert is
operated permanently with unsuitable chimney systems. For this reason we recommend that the quantity of wood added per hour during a day’s use does not drop below 2.0 kg.
The thermally actuated flue gas valve integrated in the heat ex-
changer of the H
2O fireplace insert automatically controls opera-
tion of the latter. When the flue gas temperature is sufficiently high (approx. 150°C), the flue gas valve closes automatically. This de­flects the flue gas flow through the heat exchanger. When the flue gas temperature falls below this temperature again, the flue gas valve opens. For improved efficiency of the heat exchanger, the
- 58 -
H2O fireplace insert should be lit and stoked as evenly as possible and the fire should not be allowed to subside to embers too often if uniform heat discharge from the heat exchanger is to be en­sured and low chimney temperatures avoided.
Double glazing (IR reflection): Infrared radiation from the combus-
tion chamber is largely reflected by the application of oxidic coat­ings to the glass surface. These coatings generate a “Newton’s Rings” phenomenon (similar to a rainbow), so-called IR reflection. Due to this colouring, the characteristic feature of “IR reflection” is visible and recognisable. This colouring cannot be removed.
The following conditions are required for operating the fireplace
insert at nominal heat output.
The fireplace insert has been heated up (the wood has already
been replenished 2-3 times).
Combustion must take place with the door closed.
Chimney draught: 12 Pa
14 Pa
(Varia Ah H2O and Varia A-Fdh H2O)
Wood: dry beech firewood; (moisture content < 18%)
Rate at which wood is added: see point 1.2
Air setting: Around the middle setting; depending on local
Conditions - may need to be adjusted slightly (see example).
For a combustion period of approx. 60 minutes, see point 1.2
for the total output of the fireplace insert. Example of rate of wood addition and air setting for the total output of the fireplace insert.

5. Cleaning and maintenance
For cleaning, please also refer to the notes in the operating manual for the fireplace insert. The notes in this installation and operating manual relate only to the cleaning of the heat exchanger of the H
2O fireplace insert.
Please note that cleaning may result in dirtying of the room in which the unit is installed, as well as of clothing worn. We recommend that you protect the area around the fireplace insert opening from getting dirty by means of a plastic or fabric sheet.
5.1. Cleaning the heat exchanger
It is essential that the heat exchanger be cleaned. Only if the heat exchanger is cleaned and maintained regularly and properly can it operate fully effectively. Generally speaking, cleaning must be carried out when the unit is cold. Since the heat exchanger cools the flue gases from the H
2O fireplace
insert directly, and this is bound to result in deposits on the heat exchang­er surfaces, these must be regularly cleaned with the brush supplied. The frequency of cleaning depends on several factors (intensity of use, duration of combustion, fuel, chimney draught, etc.) and is impossible to state absolutely. We recommend that cleaning be carried out about every 4 weeks. The cleaning intervals must be adapted to local conditions. When dry firewood is used and if our recommendations are followed, the cleaning intervals can be significantly extended. After the end of the heating season, thorough cleaning of all the components is required.
The heat exchanger must generally be cleaned through the combustion chamber of the fire cell. This requires opening the hearth door and removal of the flame deflector plate (flame baffle plate) from the combus­tion chamber. The thermally actuated flue gas valve is then removed through the combustion chamber (see Fig. 7a). To do this, hold the valve by the handle, tilt it slightly and pull down to remove. Residues may only be removed from the thermal flue gas valve with a cloth or brush. During this operation, no pressure should be exerted on the four wings of the flue gas valve as this could impair operation.
- 60 -
The heat exchanger tubes and the central duct as well as the outer surfaces of the heat exchanger and the smoke trap must be cleaned with the brush supplied or with a hand brush. The deposits will then automati­cally fall into the combustion chamber and can be removed from it using items generally available on the market (an ash shovel, ash broom or ash vacuum cleaner).
After cleaning, assembly is carried out in the reverse order. First, insert the thermal flue gas valve (introduce obliquely from below and place on the supports). Then insert the flame baffle plate so that the flue gas gap is

on the side where the glass is.
5.2. Cleaning the double glazing
If the fireplace insert is fitted with double glazing, cleaning may be carried out by the operator only on the combustion chamber side and on the side facing the room in which it is installed, as indicated in the operating manual. If the internal panes within the glazing vacuum are dirty, cleaning may only be carried out by customer service or a trained specialist company.
5.3 Maintenance of the heat exchanger
The hydraulic pressure of the heating system must be checked at regular intervals during the heating season. The H
2O fireplace insert may only be
operated when completely filled and bled.
A heating inspection of all the safety devices (overheat discharge valve, safety valve, etc.) and the other components must be carried out annually before the heating season. The notes in the installation and operating manuals of the respective component manufacturers must be adhered to. This check may only be carried out by a specialist company which is able to ensure proper functionality of the individual components. We recom­mend that you sign a service contract with your specialist company. The annual safety test (e.g. functional testing of the overheat discharge valve, the pump thermostat, safety valve, expansion vessel, etc.) should be carried out before the heating season. On performing the annual safety checks, your specialist company must document them in the commission­ing log. In the event of a claim, evidence of the maintenance work carried out must be submitted to the service personnel.

6. Troubleshooting
Note: The fireplace must not be used as a waste incinerator. Furthermore
it is intended for non-continuous use. Nor can continuous combustion be achieved by extracting combustion air – attempting to do this is not permitted.
You can remedy the following problems yourself:
Description of problem Solution
Overheat discharge valve keeps cutting in (constant water outflow through the outlet). The water heat exchanger cannot discharge heat to the heating system.
The buffer storage tank is “full”. Extract heat from storage tank Check operation and setting of the pump thermostat and load unit Set pump one increment higher (greater flow rate). Circulating pump not running. Pump or power connection defective? Return temperature too high,
< 70°C. Check whether shutoff devices are stuck. Sufficient heating water present?
Overheat discharge valve dripping.
Contamination of the overheat
discharge valve. Flush the overheat discharge valve
by pressing the red cap on the fit-
ting. Inspect the seat of the connection
seals and pistons (see manufactur-
er’s manual). Where necessary, fit filters to the
system upstream of the safety de-
vice (make sure minimum flow is
maintained)
Gurgling noises, boiling noises in the water-carrying parts of the H
2O cell (air in
the system)
Check system pressure  Bleed the system at the bleed valve.
In the case of newly filled or topped
up systems it will take some time for
all the air to escape. A single bleed
operation is often not sufficient.
- 63 -
Radiators do not warm up.
Close radiator thermostats once the set
room temperature is reached. The convective heat of the hearth will spread through the surrounding air.
The heating system may be sluggish
because of its configuration. It can take some time for the heating system to generate heat again.
Have the heating system balanced by
a heating engineer.
Check the heat circulating pump for
correct operation.
Bleed the system
Increased and more rapid contamination of the combustion chamber lining and glass ceramic. The combustion chamber lining no longer burns off material. It is difficult to light the fire
Remove deposits in the heat exchang-
er and in the connecting pipe to the chimney.

wood addition rate wood moisture content <20%
Check chimney draught Inspect load unit.
If there are any further problems contact your fireplace manufactur­er/heating installer. Only spare parts supplied by the manufacturer may be used.
