1. OPERATING INSTRUCTIONS

1.1 Before using

Before the wood stove is used make sure re­quired installation conditions, are met. See page

1.2 First firing

Heta wood stoves are, treated with a heat-resi­stant coating, which hardens at a temperature
of about 250° C. This curing process will cause
some smoke and odor, so there should be suf­ficient ventilation in order to avoid the door seal
sticking to the stove during this curing process,
open the door every ten minutes during the first
two hours of the first firing.

1.3 Regulating the air flow

The stoves combustion air is regulated by means
of a handle below the firing door.

The air is full open to the right, closed to the left.

1.4 Lighting the stove

Place two pieces of wood on the bottom. Stack

kindling on top in layers with air between. Set
ting fire starter (bag, brick, paraffin) on the top,
now you are ready to light the fuel. The flames
must work from the top down

The use of lighter fluid, oils or any

liquid fuels is strictly forbidden

from use in a wood stove.
Fully open the combustion air into the start-up

air position and the door ajar (about one cm
open). Once the fire is established and the chim­ney is hot (after about ten minutes) closed door
and regulate the air into operating position. We
recommend, all of the first fuel is burned with
the combustion air fully open in the operating
position. This ensures the stove and chimney
are thoroughly heated.

Startup/Lighting
Scan the code and select a language.

1.5 Refueling

Refueling of your stove should be done while
there is still a good layer of embers. Distribute­the embers with the majority of them to the front.
Place pieces of wood equivalent to about 1 kg
on top of the embers perpendicular to the door.
Now open the combustion air completely. If the
stove and/or chimney cools down too much, it

may be necessary to use the start-up air and
possibly have the door ajar.

The wood will then ignite within a very short time
(Typically 1 to 3 minutes). Once the fuel is Ignited

.
Close the door and regulate the air back to ope­rating air. When the fire is well established, you
can now regulate the operating air to the desired
combustion level.

Rated output (see DOP of page 2) measured
when the combustion air is about 80% open.

Ensure when refueling that the wood is not too
close, it will cause poorer combustion, less heat
out-put and lower efficiency.

The fuel load, must be maintained below the top
series of air holes and within the outer vent in
each side. Fig. 5

When refueling be careful to place
the fuel into the combustion

cham­ber gently, (use the provided glove).
By not doing so you risk cracking or
breaking the vermiculite.

If there is reduced draft in the chimney, we re­commend opening a window at stoking. This will
give better ventilation to the room and more oxy­gen for combustion.

1.6 Emptying the ash

By using the shaker grate, it rotates back and
forth so the ash falls through the holes and into

the ashtray, see Fig. 6. It is advantageous to
leave a layer of ash in the bottom of the combu­stion chamber on top of the grate as insulation.
For emptying the ash pan - use the supplied
handles 1020-0001 use of the ashtray tool, see
Fig. 7.

It is an advantage for the next firing to leave a
layer of ash lying in the bottom of the firebox.

Be careful when emptying the
ashes out. There can be hot embers
left for a long time.

1.7 Reduced burning

The stove is, designed for intermittent use.
It is important to maintain the layer of hot em-

bers. Lower heat out-put occurs when no flames
come from the tree, when it is becomes glowing
charcoal.

If you are looking for less heat out-put, achieve
this by fueling with smaller volumes of wood and
a lower operating air. You may not completely
close the operating air during firing.

Be aware that the stove will naturally soot if the
operating air is too low. This is not good for the
environment. There is also a risk for the glass,
t

he chimney and other parts will become sooted.

By a combination of the above and possibly
burning damp wood. Can lead to high levels of
soot that it becomes sticky. Causing the sealing
of the door to tear off when opening the door
the next day.

1.8 Explosion!!!

It is very important never to leave
The stove after start up or refueling,
before the fire is established.
(Typically 1 to 3 minutes)

Explosion can occur if filled with too much fuel
in the stove, the production of large volumes of

gas, which can explode if the air supply be­comes too low.

Warning!

One must always use cation around
the stove seen, as it gets very warm
during use. (In excess of 90° C).

Children should avoid contact with the stove.

Setting up a fence if you have small children may
be necessary.

Do not place flammable objects like drying racks,
furniture, curtains too close to the stove.

1.9 Draft conditions
and the chimney

Poor draft will not allow the stove to burn, as it
should. The glass can soot, requires cleaning of
the chimney more often, smoke can escape out
when the door is open and it gives poor fuel ef­ficiency. Leading to unnecessary polluting of the
environment.

Good draft will allow the stove to achieve op­timal combustion and the highest possible ef­ficiency. Heta wood stoves are constructed so
that it itself provides an optimal blend of com­bustion air. This provides a high efficiency/heat,
clean glass and low environmental impact.

Minimum chimney draft for
Inspire 40-40H: 13

pascal

, Inspire 45-45H: 12

pascal

and Inspire 55-55H: 12

pascal

.

It is the draft that the stove has been tested and
approved on. The minimum draft is necessary
to provide clean burning, beautiful flame pictu­re, as well as achieving the rated efficiency.

There is a risk of smoke escaping into the room
if the door is opened during vigorous firing, or if
there is a lack of air supply to the room, for ex. if
an extraction fan is in use.

Flue gas temperature at the rated output is for
Inspire 40-45H 263°C, relative to

20°C

Inspire 45-45H 221°C, relative to

20°C

Inspire 55-55H 263°C, relative to

20°C.

Flue gas flow is:
Inspire 40-40H: 3,7 g/sec.
Inspire 45-45H: 4,1 g/sec.
Inspire 55-55H: 5,7 g/sec.

The chimney height and diameter, as well as
the temperature difference between the flue gas
and outside temperature generates the chimney
draft. Chimney insulation is therefore important
as new efficient stoves create lower flue tempe­ratures. Wind and weather conditions also in­fluence draft, in some cases it may be disad­vantageous wind direction, combined with the
position of the chimney can cause negative draft
(it blows through the chimney), causing smoke
escape from the stove.
Before using after a long period of inactivity,
check that the chimney is free for any blocka­ges. (soot build-up, bird nests, leaves etc.).

Reduced draft can occur when:

• The temperature difference is too small
between smoke gasses and outdoor
temperature, for ex. poorly insulated chimney

• To short of a chimney

• The outside temperature is high, and indoor
temperature is low f. ex. in summer

• False air in the chimney

• Chimney is blocked

• Air tight house (lack of combustion air supply)

• Poorly placed chimney for the surroundings,
for ex. the ridge and trees may cause
turbulence

Good draft occurs when:

• The difference in temperature in the chimney
(warmer) and outside temperature (colder)

• It is clear weather

• The chimney has the right height min 4 meters
above the stove, and clear of the roof ridge

1.10 Fuel

Your new stove is EN approved for firing with
wood fuel. You must therefore only burn clean,
dry wood in your stove. Never use your stove
to burn driftwood, as this may contain a lot of
salt which can damage both the stove and the

11

chimney. Similarly, you must not fire your stove
with refuse, painted wood, pressure-impregna­ted wood or chipboard, as these materials can
emit poisonous fumes and smoke.

Correct firing using well seasoned wood pro­vides optimal heat output and maximum effi­ciency. At the same time, correct firing prevents
environmental damage in the form of smoke
emissions and reduces the risk of chimney fires.

If the wood is damp and inadequately seasoned,
a large proportion of the energy in the fuel will
be used to vaporize the water, and this will all
disappear up the chimney. Thus, it is important
to use dry, well seasoned wood, i.e. wood with a
moisture content of less than 20 %. Achieve this
by storing the wood for 1–2 years before use.

Pieces of firewood with a diameter of more than
10 cm should be split before before storing. The
pieces of firewood should be of an appropriate
length (approx. 19-25 cm) so that they can lie
flat on the bed of embers.

If you store your wood outdoors, it is best to
cover it.

a moisture content of 18%.

Mountain pine 600 Poplar 450
Willow 560

It is advised not to use oil-containing woods
like teak tree and mahogany, as this can cau­se damage to the glass.

Heating value in wood

You have to use about 2.4 kg normal wood to
replace one litre of heating oil. All woods have
almost the same heating value per kg, which is
about 5.27 kW/hour for absolute dry wood.
Wood with a moistness of 18% has a efficiency
of about 4.18 kW / hour per kg, and one litre

heating oil contains about 10 kW / hour.

CO2 release

At combustion 1000 litres of heating oil forms

3.171 tons CO2. As wood is a CO2 neutral heat/
energy source, you save the environment about

1.3 kg CO2 every time you have used 1 kg normal
wood.

1.11 Operational problems

The chimney must be swept at least once a
year, we recommend the use of a NACS (natio­nal association of chimney sweeps) registered
chimney sweep.

In the event of smoke or malodorous fumes are
being produced, you must first check to see
whether the chimney is blocked.

The chimney must, of course, always provide
the minimum draft necessary to ensure that it is
possible to regulate the fire. Please note, how­ever, that chimney draft is dependent on the
weather conditions. In high winds, the draft can
become so powerful that it may be necessary to
fit a damper in the flue gas pipe to regulate the
draft.

When cleaning the chimney, soot and other
deposits may come to fall on the baffle plate,
remove and clean it. In cases where the wood
burns too quickly, this may be due to excessive
chimney draft. You should also check to make
sure that the door seal and ash pan seal is intact
and correctly fitting.

If the stove it generating too little heat, this may
be because you are firing with wet wood. In this
case, much of the heating energy is used to dry
the wood, resulting in poor efficiency, poten­tially damaging the vermiculite and an increased
risk of soot deposits in the chimney.

1.12 Chimney fire

In case of a chimney fire, which often results from
incorrect operation/maintenance or prolonged
use of damp wood, close the door and the air
supply completely, to help slow/smother the fire.

Call the fire department.

1.13 Troubleshooting table

Fault Cause Troubleshooting Solution

Lighting problems. When the
stove is cold, smoke seeps
into the room. Once the com­bustion chamber has heated
up, the stove burns well.

Inadequate chimney draft.
The chimney only has
sufficient draft when it is hot.

You can test using a lighter whether
flame is drawn into the combustion
chamber.

Improve the chimney.

The stove burns poorly after
the warm-up phase,

and the

glass slowly soots up.

Soot in the flue pipe. Check the flue pipe regularly, as the

problem arises slowly.

Clean regularly, and limit the use
of horizontal flue pipes. Do not use
firewood which generates large
quantities of ash.

Inadequate chimney draft.

The fault usually already occurs during
lighting. Measure the chimney draft

.

Improve the chimney draft.

Insufficient air supply. Check the air supply. Read the operating instructions and

instruct all users.

Damp wood. Use clean, dry wood with a maximum

moisture content of 20%.

Firewood should ideally be dried for
at least one year after splitting.

Firewood pieces too large. The optimum size is a length of 25 cm

and max. diameter of 10 cm.

Use smaller pieces of firewood.

Insufficient air supply to the
room. Range hoods, airtight
windows, etc.

Ensure there is sufficient fresh air
supply, open a window, check the
outdoor air supply.

Depending on the cause, windows
must be opened or the outdoor air
connection cleaned.

The vermiculite in the
combustion chamber is
becoming very worn.

Wood and flue gases wear
down the vermiculite.

Investigate whether the wear is
normal.

Normal wear and minor cracks are of
no significance. It should be replaced
when the steel of the combustion
chamber is visible.

Too rapid combustion. Too much chimney draft. T

o test, you can open the cleaning

hatch, but remember to close it again.

Measure the chimney draft and install
a damper in the flue pipe if necessary.

The door or ash pan/drawer
seal is defective.

While cold, close a piece of paper in
the door – the seal should hold the
paper gently in place so it does not
fall out by itself. Normal wear.

Replace the seal.

The vermiculite in the
combustion chamber is
cracked.

Shocks or impacts while
adding firewood.

Normal wear Cracks only have cosmetic signifi-

cance. Replace when the steel of the
combustion chamber is visible.

Steel surfaces in the
combustion chamber
have oxidised.

The temperature in the
combustion chamber is
too high.

Unsuitable fuel is being used (such as
coal). Check the quantity of firewood
being used, read the operating
instructions.

If there are clear cracks or weak­nesses in the stove body, it must be
replaced.

The stove whistles Too much chimney draft To test, you can open the cleaning

hatch, but remember to close it again.

Install a damper.

The stove 'clunks' Usually due to tension in the

metal plates.

Generally only occurs while heating
up and cooling down.

Adjust the metal plates.

The stove ticks Normal expansion and

contraction due to
temperature changes.

A normal sound. Ensure that the temperature in the

combustion chamber is as constant
as possible.

The stove creaks. The temperature in the com-

bustion chamber is too high.

Use less firewood. Also check the seal
in the ash pan/drawer.

1.14 Maintenance

The surface of the stove is treated with a heat­resistant paint. The stove should be cleaned
with a damp cloth.
Any damage to the surface in the form of chips
or scratches can be repaired using touch-up
paint, which is available in spray cans.

1.15 Cleaning the glass

Incorrect firing, for example using wet wood,
can result in the viewing window becoming
covered in soot. This soot can be easily and
effectively removed by using proprietary stove
glass cleaner.

Remember

The stove and chimney installation, must comply with
local regulations, including those referring to national
and European standards.

20

2. Installation instructions

The stove installation must be in accordance
with national, European and possibly local regu­lations. You must follow local regulations with
regard to installation of chimney and connection
to the chimney. We recommend that you let a
professional Heta dealer install the stove. Alter­natively, you can ask the local chimney sweep
before installation. Be aware that it is always the
owner himself who has responsibility for ensu­ring that applicable rules are complied with.

A modern stove places heavy demands on the
chimney due to the high efficiency. It may be
necessary to enhance or even replace an old
chimney.

Remember

1. Always ensure free access to any cleaning
doors in a chimney.

2. Always ensure ample fresh air to the room.

3. Exhaust/extraction fans in the house can re­duce or create negative draft in the chimney.
Reduced draft can lead to the stove having
a

dverse combustion properties. It may result
in smoke coming out of the stove when the
door is open. A negative draft due to an
exhaust/extraction fan can cause the chim­ney to work in reverse, drawing smoke into
the house because of the fan.

4. Any air vents must not be covered.

2.1 Distance Provisions

There is a difference between installation next

to
flammable wall or non-flammable wall. If the wall
is made of non-flammable material, the stove

in

principle may be placed flush against it.
We recommend a minimum of 5 cm to facilitate

air circulation around the stove.
The minimum distance to combustibles can be

found on the model plate provided with the sto­ve or on page 18 of this manual.

Pay special attention to the distance to flamma­ble floor, which is also applicable, although there
is a steel/glass plate on the floor. The floor must
be constructed of f. eg. concrete, tile or similar
non-combustibles up to 170mm valid from the
bottom edge of the stoking door of the stove.
170 mm for Inspire 40-40H,
120 mm for Inspire 45-45H,
430 mm for Inspire 55-55H

2.2 Floor

You must ensure that the floor can support the
weight of the stove and a top-mounted steel
chimney.

In front of the fireplace insert, the substrate
must consist of non-combustible material, for
ex. Steel/glass plate, stone or tile floor. The size
of the non-combustible surface must follow the
applicable national and local regulations. Pro­tecting your floor from embers that may fall out
of the oven.

Distances see data table page 18.
Pay special attention to the distance from flam-

mable floor, which is also valid even if there are
a steel, glass, stone or tile over flammable ma­terials. It is the floor itself, which must be non­flammable. (Concrete, tile or similar). These
stoves can be installed on a 12 mm non com­bustible hearth.

2.3 The chimney connection

The chimney opening must follow national and
local regulations. However, the area of the ope­ning should never be less than 115 cm

2

, which
corresponds to a diameter of 121 mm. If a damper
is fitted in the flue gas pipe, there must always
be at least 20 cm

2

of free passage, even when

the damper is in its “closed” position.
If local regulations permit, two contained stoves

can be connected to the same chimney. How­ever, you must abide by local regulations regar­ding the distance between the two connections.

The insert stove must never be connected to
a chimney that is linked to a gas fire stove.

Connection to a brick chimney

Brick a thimble into the chimney and seat the
flue gas pipe in this.

The thimble and flue gas pipe must not penetra-

An efficient stove makes high
demand on chimney

properties
– so always have your local
chimney sweep evaluate your
chimney.

21

te the chimney opening itself, but must be flush
with the inside of the chimney duct. Joins bet­ween brickwork, the thimble and flue gas pipe
m

ust be sealed with fireproof material and / or

beading

. Heta A/S stresses that it is of utmost

im

portance that this is done correctly with very

tight joints

. As mentioned earlier, we recommend
that setup and installation be left to a profes­sional Heta dealer.

Connection to a steel chimney

When fitting a connection from a top outlet stove
directly to a steel chimney, we recommend fit­ting the chimney tube inside the flue gas spigot
so that any soot and condensation drops into
the stove itself rather than collecting on the ex­terior surface of the stove.

For connections to chimneys that are run through
ceilings, all national and local regulations regar­ding distance to flammable material must be fol­lowed. It is important that the chimney is fitted
with roof support so that the top panel of the
stove is not required to bear the entire weight
of the chimney (excessive weight may damage
the stove).

2.4
Combustion air and Ventilation

The insert stove is approved as a room air depen­dent insert stove in accordance with EN 13240.
All the combustion air in the inset stove comes
from the room in which it is fitted. However, by
connecting a sealed air inlet to the insert stove’s
air intake connector, the stove can be supplied
with external combustion air. In this respect, the
following requirements must be met:

• Only approved materials may be used from
the ventilation unit to the air inlet vent.

• The air inlet vent must be fitted correctly and
insulated to prevent formation of condensate.
The cross section of the vent and grille must
be at least 78 cm².

• If the vent leads out into the open air, please
note that the grille must be fitted with suitable
wind protection. There must be no risk that
the grille can get clogged by leaves, etc.

Ventilation

Adequate ventilation must be provided in ac­cordance with building regulations (Doc J Oct

2010) especially when installing in newer build
properties when the stove is not going to be in­stalled to an outside air supply.

The Inspire 40-40H, 45-45H and 55-55H has a
nominal output of less than 5kW and does not
need additional ventilation in older properties
where it will be ventilated
by natural leakage.

Houses built after 2008 where the air leakage
rate is less than than 5 m3 / hour / m2 then a ven­tilator equivalent to 550 mm2 per kW output will
be required (4.5 kW x 550 mm = 2475 mm2) un­less the stove is connected to an outside fresh
air supply.

4. Appendix A

The Clean Air Act 1993 and Smoke Control
Areas Under the Clean Air Act local authorities
may declare the whole or part of the district of
the authority to be a smoke control area. It is
an offence to emit smoke from a chimney of a
building, from a furnace or from any fixed boiler
if located in a designated smoke control area. It
is also an offence to acquire an ”unauthorised
fuel” for use within a smoke control area unless
it is used in an ”exempt” appliance (”exempted”
from the controls which generally apply in the
smoke control area).

The Secretary of State for Environment, Food
and Rural Affairs has powers under the Act to
authorise smokeless fuels or exempt applian­ces for use in smoke control areas in England.
In Scotland and Wales this power rests with
Ministers in the devolved administrations for
those countries. Separate legislation, the Clean
Air (Northern Ireland) Order 1981, applies in

Northern Ireland. Therefore it is a requirement
that fuels burnt or obtained for use in smoke
control areas have been ”authorised” in Regula­tions and that appliances used to burn solid fuel
in those areas (other than ”authorised” fuels)
have been exempted by an Order made and sig­ned

by the Secretary of State or Minister in the

devolved administrations.
The Inspire 40 have all been recommended as

suitable for use in smoke control areas when
burning dry wood logs.

Further information on the requirements of the
Clean Air Act can be found here: https://www.
gov.uk/ smoke-control-area-rules

Your local authority is responsible for imple­menting the Clean Air Act 1993 including desig­nation and supervision of smoke control areas
and you can contact them for details of Clean
Air Act requirements.
