InstallatIon
In general
Congratulations on your new HWAM woodburning stove.We are pleased that you have chosen a HWAM
woodburning stove and confident that it will give you much pleasure.To ensure optimum operation and
safety, we recommend that the installation should be carried out by an authorised HWAM retailer or
a fitter recommended by the retailer. For an overview of HWAM retailers, visit www.hwam.com under
“Retailer locations”.
Safety
The installation of your HWAM woodburning stove must always comply with all European, national and
local building regulations.The installation must be carried out in accordance with the instructions in the
installation and user manuals and subsequently registered with the local authorities. Upon installation,
the chimney sweep must approve the installation before you can start using the woodburning stove.All
HWAM woodburning stove packaging material must be handled in accordance with local waste manage-
ment regulations.
Room requirements
Always ensure a supply of fresh combustion air to the room where the stove is to be installed. The
woodburning stove uses approx. 6-23 m3 of air per hour.A window that can be opened or an adjustable
air valve will be sufficient. It must not be possible to block the adjustable air valve/grate. In newly built/
airtight dwellings, we recommend that a fresh air system should be installed for the direct supply of
external air to the combustion.This fresh-air system may be bought separately.
Before installing the stove, you must ensure that the load-bearing capacity of the floor can withstand
the weight of the stove and the chimney. The weight of the chimney should be calculated according to
its dimensions and height.

Remember to pay attention to the applicable regulations concerning the required distance
between the wall and smoke pipe.
The distance to a brick wall is set to faciliate the servicing of the HWAM®Autopilot™.
Please be aware that not all glass parts are heat-resistant. For this reason, a glass wall should sometimes
be treated as a combustible wall, in which case we ask you to contact your local chimney sweep or glass
producer to hear at what distance the stove should be kept from glass.
Requirements for chimney and smoke pipe
The height of the chimney must ensure sufficient draught and prevent any smoke nuisance.As a general
rule, satisfactory draught conditions are achieved if the chimney is 4 m above the stove and at least 80
cm above the ridge. If the chimney is placed at side walls, the top of the chimney should always be higher
than the ridge or the tallest point of the roof.Always be aware of any national and/or local regulations
applying to thatched roofs and the location of the chimneys.
The woodburning stove requires a minimum draught of 1 Pa (measured at EN 13240 measurement point).
If measured just above the smoke flue socket, the chimney draught must be 17-19 Pa.
The chimney must have a minimum clearing of Ø 150 mm. The chimney must be provided with an
easily accessible cleaning door.The chimney and flue duct must be of flue class T400 and be CE marked.
Furthermore, it must have obtained the classification of G in soot fire testing.The required distance to
combustible material must be complied with in accordance with the brand label.Ask your HWAM retailer
for further information.

Connection to chimney
All the stoves have both back and top smoke outlet that can be connected to an approved steel chimney on
top or directly out at the rear to a chimney.
Make sure that the chimney is tight and that no false draft is caused around neither the cover plate, in
connection with a covered smoke outlet, nor the cleanout door and pipe connections. Please note that
bent and/or horizontal smoke pipes will reduce the effect of the chimney draft.

Fitting the loose parts
Before the stove is installed,you must ensure that all loose parts are fitted correctly. Check that all insula-
tion plates of the combustion chamber have been properly placed, i.e.that the bottom plate is horizontal
and that the side plates are vertical and reach all the way up to the steel sides of the combustion chamber
and down to the bottom plate.

Chimney
The chimney is the “engine” of the stove and it is crucial for the functioning of the woodburning stove.
The chimney draft provides a partial vacuum in the stove.This vacuum removes the smoke from the stove,
sucks air through the dampers for the so-called glass pane rinse which keeps the glass free of soot, and
sucks in air through both primary and secondary dampers for the combustion.
The chimney draft is created by the differences in temperature inside and outside the chimney.The higher the
temperature within the chimney, the greater the draft.It is crucial, therefore,that the chimney is warmed up
properly before closing the damper and limiting the combustion in the stove (a brick chimney takes longer to
warm up than a steel chimney).On days where the weather and wind conditions create insufficient draught
inside the chimney, it is even more important to warm up the chimney as quickly as possible.The trick is to
quickly get some flames going. Split the wood into extra fine pieces, use an extra firelighter, etc.
If the stove has not been used for a longer period,it is important to check that the chimney pipe is not blocked.
It is possible to connect several devices to the same chimney. However, it is important to first check the
applicable rules.
Chimney sweeping
To prevent the risk of chimney fires,the chimney must be cleaned every year.The flue duct and the smoke
chamber above the baffle plate must be cleaned together with the chimney. If the chimney is too tall to
be cleaned from above, it must be equipped with a soot door.
In case of a chimney fire, close all dampers and call the firefighters. Before any further use, have the
chimney checked by the chimney sweeper.
FIrIng manual - wood
Your first heating session
The lacquer will be fully hardened after the stove has been used, and the door and the ashpan should be
opened very carefully as there will otherwise be a risk that the gaskets will stick to the lacquer. In addi-
tion the lacquer may initially give off an unpleasant odour, so make sure that the room is well ventilated.
Tips about fuel
Approved fuel types
The wood burning stove is EN approved for combustion of wood only. It is recommended to use dried
chopped wood with a water content of a maximum of 18%. Stoking a fire with wet wood results in soot,
environmental problems, and a less efficient fuel economy.
Recommended wood types
All types of wood,for instance birch, beech, oak,elm,ash, conifers, and fruit trees can be used as fuel in your
insert.The great difference is not in the fuel value, but in the weight of the wood types per cubic metre.
Beech weighs more per m3of wood than common spruce, for instance.This is why more common spruce
is required, in terms of volume, to obtain an amount of heat similar to that of beech. Heavy types of wood
such as ash, beech, oak and elm are generally not that easy to light up. In addition, they burn more slowly and
give off more embers. Light types of wood such as birch, maple, spruce and pine are more easy to light up.
They burn faster and give off fewer ambers.You may therefore take advantage of the light types of wood for
lighting and use the heavier types of wood to ensure a longer burning time..
Banned fuel types
It is not allowed to stoke a fire with the following: printed matter, plywood, plastic, rubber, fluid fuels,
and rubbish such as milk cartons, lacquered wood or impregnated wood and fossil fuels.The reason that

Page 14 of 20 pages
you should not apply any of the above is that during combustion they develop substances that are health
hazardous and harmful to the environment.These substances could also damage your wood burning stove
and chimney, rendering the product warranty void.
Storage of wood
A moisture content of 12-18% is achieved by storing recently felled wood outdoors under a lean-to
for at least one year, preferably 2 years.Wood stored indoors has a tendency to become too dry and
combust too quickly. However, it might be advantageous to store fuel for lighting a fire indoors for a few
days prior to use.
It is recommended to purchase a wood moisture meter to continuously check that the firewood has the
correct moisture content before using it for firing.Split the wood and measure the moisture content of
the split surfaces.
Recommended dimensions
The dimensions of the fuel are important to good combustion.The dimensions should be as follows:
Fuel type Length in cm Diameter in cm
Wood for kindling a fire (finely chopped) 25-33 2-5
Chopped wood 25-33 7-9
Special lighting guide for wood-burning stoves with stone cladding
Stones are a natural product that must be allowed to adapt to fluctuations in temperature.We recom-
mend following the procedure below:
1. First stoking
Move the air control knob (drawing E, 1) to top position.Place two pieces of wood
(5-8 cm in diameter) horizontally in the bottom of the combustion compartment
(corresponding to 1-2 kg). Place 5-8 pieces of kindling randomly on top.Place two
firelighters between the top layer of kindling. Light up the fire-lighters and close
the stove door. If condensation forms on the glass, keep the door ajar for a little
while and close again.When the fire has gone out, open the door and leave it open
while the stove cools to room temperature.
2. Second stoking
Move the air control knob (drawing E, 1) to top position. Place two pieces of wood (5-8 cm in diameter)
horizontally in the bottom of the combustion compartment (corresponding to 1-2 kg). Place 5-8 pieces
of kindling randomly on top. Place two firelighters between the top layer of kindling. Light up the fire-
lighters and close the stove door. If condensation forms on the glass, keep the door ajar for a little while
and close again.
When there are no more visible yellow flames, and a right ember is there, you can fire again.The layer of
embers is suitable when the pieces of wood begin to disintegrate and the bottom of the stove is covered
by embers.Put at least two pieces of wood into the stove, weighing up to 1 kg each.When all of the wood
has caught fire, move the air control knob (1) to middle position.Allow the fire to burn and let the stove
cool to room temperature before stoking again.
3.Third stoking
Repeat the procedure for the second stoking. Allow the fire to burn and let the stove cool to room
temperature after the fire has gone out.
Restoking:
Follow the general instructions, see the sections “Lighting the stove” and “Stoking”.
Lighting the stove (drawing E)
A successful combustion process requires that the wood is lit in the right way.A cold stove and a cold
chimney challenge the combustion process. Be careful to make a good lighting with suitably dry wood,
using kindling and lighting the fire in the top layers of kindling. It is important to achieve a high flue gas
temperature quickly.

Page 15 of 20 pages
Move the air control knob (drawing E, 1) to top position.Place two pieces of wood
(5-8 cm in diameter) horizontally in the bottom of the combustion compartment
(corresponding to 1-2 kg). Place 5-8 pieces of kindling randomly on top.Place two
firelighters between the top layer of kindling. Light up the fire-lighters and close
the stove door. If condensation forms on the glass, keep the door ajar for a little
while and close again.
When the kindling is burning well, move the air control knob (1) to middle position. If the fire goes out,
move the air control knob to maximum position again (to the top) until the fuel catches fire.Then move
the air control knob to middle position again. Allow the kindling to burn up completely until there are
no longer any visible flames.The stove can then be stoked again.
Important! The ash pit must not be opened when lighting up. It must always be closed when the stove
is in use. Otherwise the HWAM®Autopilot™ does not function.The door should only be opened when
lighting up, when restoking, and when cleaning the stove. Never leave a stove before there are lasting
flames in the wood after firing!
Stoking (drawing E)
When there are no more visible yellow flames, and a right ember is there, you can fire again.The layer of
embers is suitable when the pieces of wood begin to disintegrate and the bottom of the stove is covered
by embers. Put at least two pieces of wood into the stove, weighing up to 1 kg each. Do not regulate
the stove again as the HWAM®Autopilot™ will do this, but the temperature can be adjusted with the
air control knob (1). Moving it down will reduce the rate of combustion and the stove will burn slower.
Moving it up will increase the temperature and the stove will burn faster.Wait until the layer of embers
is suitably low before stoking again.
During combustion, the outer surfaces of the stove will become hot, and due care must
therefore be shown.
When burning is complete
Close the air control knob when the stove is not in use.
Cleaning the glass
We recommend wiping the glass after a fire.This is best done using a paper towel.
Fuelling with coal or pet coke
The stove is not approved to use coal or pet coke as a fuel.
Operating the heat compartment damper
There is a damper at the back of the stove between the top plate and the heat compartment that opens
and closes the flow of convection air in the heat compartment.The supply of convection air can be opened
by moving the damper to the left and closed by moving the damper to the right.
We recommend that the convection damper is kept closed when fuelling the stove in order to heat up
and thereby store heat in the heat storage stones in the heat compartment as rapidly as possible.
Keeping the convection damper closed retains the heat stored in the heat storage stones as long as pos-
sible.When the damper is opened, the heat from the heat storage stones in the heat compartment will
rapidly be transferred to the room.

FIrIng In general
Rapid or fierce heat
Rapid or fierce heat is obtained by burning many small pieces of wood.
Maximum amounts of fuel:
The maximum allowed amount of fuel per hour is:
Wood: 2.5 kg
If these limits are exceeded,the stove will no longer be covered by the factory guarantee,and it may also
become damaged due to excessive heat.The stove has been approved for intermittent use.
Typical re-firing interval
Typical re-firing interval at nominal performance
Wood: 45 min (1,33 kg)
Prolonged burning time
The longest combustion is achieved by pushing the air control knob to its lowest position (drawing E,
item 1). However, with the air control knob in this position, it may be difficult to keep the flames alive
after refuelling. If so, it will help to adjust the air control knob to about 1/5 for the first 25 minutes or so
after refuelling.The stove can then be adjusted to minimum again. Remember that there must be visible
flames for proper combustion to take place.
Insufficient firing
If the fireproof materials in the combustion chamber are blackened after a fire, then the stove is polluting,
and the HWAM®Autopilot™ is malfunctioning. It will be necessary, therefore, to move the air control
knob to a higher level. It may also be necessary to burn more wood.
How to achieve the best combustion
• Use clean and dry wood.
Wet wood results in inefficient combustion,plenty of smoke, and soot. Furthermore, the heat will dry
the wood, not heat up the room.
• The fire should only be stoked with a little wood at a time.
You achieve the best combustion by starting up a fire often and using only a little wood. If you use
too much firewood, it will take some time before the temperature reaches a level where you achieve
a good combustion.
• Make sure there is the right amount of air.
You should also make sure that there is plenty of air – especially in the beginning - so the temperature
in the wood burning stove climbs quickly. In this way the gasses and particles released during the
combustion will be consumed by the fire. Otherwise they build up soot in the chimney (constituting
a chimney fire risk) or will be released in a non-combusted state into the environment.The wrong
amount of air supply creates inefficient combustion and a modest effect.
• Don’t savour the fire during night time.
We advise against adding fire wood to your stove and reducing the air supply at night in an attempt
to still have some embers left in the morning. If you do so, large amounts of hazardous smoke will be
emitted, and your chimney will be exposed to unnecessarily large amounts of soot with the risk of a
chimney fire.

maIntenance
Cleaning
Any maintenance of the stove should only be carried out when it is cold. Daily maintenance is limited to
vacuum cleaning the stove externally, using the soft brush attachment.You can also dust the stove using a
dry, soft cloth or brush. But remember, only when the stove is cold. Do not use water, spirit or any other
kind of cleaner, as this will damage the lacquer.
Once a year, the stove should be thoroughly serviced.The combustion chamber should be cleared of ashes
and soot. The hinges and the closing hook must be greased with liquid copper fat spray (heat-resistant up
to 1100°C), see drawing I. Lift the door approx. ½ cm and spray copper fat onto the hinge leaf.
Service inspection
Your stove should be given a thorough, preventive inspection once every two years.This includes:
• Thorough cleaning of the stove.
• Checking the spring in the HWAM®Autopilot™. Replace if necessary.
• Checking gaskets. Replace gaskets if they are not intact or are no longer soft.
• Checking and/or replacing insulation material.
• Checking the bottom and/or shaking grate.
• Use copper grease for hinges and locking hooks (see drawing I).
All service checks must be performed by an authorised fitter. Use only original spare parts.
Inside cleaning
The air control knob must be moved to bottom position before sweeping to prevent soot and ashes
from entering the HWAM®Autopilot™. Unless the safety fittings for transportation have not already
been removed, twist the safety fittings for transportation off the two hooks by using pliers or a screwdriver.
The smoke shelf and baffle plate is to be removed from the stove before cleaning (drawing F):
• Lift the smoke shelf (1) off the steel rail (2) at the back of the combustion chamber.Then lower it
beneath the holder (3) and tilt it out.
• The baffle plate (4) is lifted from the holders (5), under the top plate and edged out.
Ashes
It is easiest to empty the ash pan by pulling a plastic bag over it, turning it upside down and then carefully
removing it from the bag.Ashes are disposed of via the domestic waste collection.
Please note that there may be embers in the ashes for up to 24 hours after the fire has
gone out!
Insulation
The efficient,but porous insulation of the combustion chamber may, in time,be worn and damaged.Cracks
in the insulation are irrelevant to the efficiency of the stove. However, it should be replaced, if there are
actual holes due to parts of the lining falling off or when, due to wear and tear, it has been reduced to
less than half its original thickness.
HWAM®Autopilot™ (Drawing G)
Lift off the rear panel. On a cold stove,the starting point of the feeler is controlled.The starting point on
a cold stove is about 100 above horizontal.
It should feel easy going and bouncy when you push it, no matter if the stove is cold or hot. By rising or
falling temperatures it must not move at a bound.The damper plates must be dry and clean and slide
together unhindered. Control bars and slide gates may have to be smeared with WD40 (never oil).

Page 18 of 20 pages
A sooty glass door can easily be cleaned with a piece of moist kitchen roll dipped in ash. Go about it in
vertical movements (up and down). Follow up with a dry piece of kitchen roll.
Seals
Check frequently to ensure that seals in the door and ash pan are intact and not brittle. Failing this, they
should be replaced. Use original seals only.
Surface
Usually,it is not necessary to any treatment to the painted surfaces of the wood-burning stove.Any damage
to the paint may, however, be remedied with spray paint, which can be bought from your stove retailer.
Guarantee
The guarantee does not cover damage due to insufficient maintenance!
operatIonal problems
Blackened glass
• The wood is too damp. Only use wood stored for at least 12 months under cover and with a moisture
level not exceeding 18% RH.
• The door gasket may be leaking.
Smoke in the room when opening door
• The grate in the chimney may be closed. Open the grate.
• Insufficient chimney draft. See section on chimney or contact chimney sweep.
• Soot door leaking or dislodged. Replace or refit.
• Never open the door when there are still flames on the wood.

• Faulty seal in door. Fit new seal.
• If there is an excessive chimney draft, it may be necessary to close the air control knob. Close the
air control knob when the stove is not in use.
• If the steel plates in the combustion chamber develop scales or become deformed, this is due to exces-
sive heat. Stop using the stove and contact the retailer.
At interruptions that you cannot yourself rectify, you should contact the retailer.
