HWAM® SMArtControl™
Congratulations on your new wood-burning stove complete with a HWAM®SmartCon-
trolTM
We are pleased that you have chosen a HWAM woodburning stove and confident that it will give you
much pleasure.
The HWAM®SmartControlTM is a digital control of the combustion in your new wood-burning stove.
The purpose of the HWAM®SmartControlTM is to control the combustion in an environmentally
optimal and economically efficient way, with a view to generating greater user comfort.
The HWAM®SmartControlTM is a new patented technology, which electronically adjusts the air supply
to the combustion chamber. Your new wood-burning stove continually measures the temperature and
the oxygen levels of the combustion. Moreover, it is programmed to supply oxygen to the fire through
three important air inlets in the right amount, and at the right time and place in the combustion chamber.
By downloading a free app for your smartphone or tablet, you can use the app among other things:
to set the thermostat to the desired room temperature level, choose time for night-time reduction
and keep your stove updated. The app also gives you current information on burning in the stove. See
details in separate manuals for the app IHS Smart ControlTM or in the Quickguide.
.
Your new wood-burning stove and the HWAM®SmartControlTM will ensure the cleanest possible
combustion as well as a good fuel economy, regardless of external conditions such as the type of
firewood used, the chimney, the user’s experience, and other external circumstances.
The HWAM®SmartControlTM consists of the following components:
• Air box: the Air box contains a printed circuit board/software, as well as three motors and
dampers that control primary, secondary, and tertiary combustion air. The fresh air system can
be mounted on the Air box to the back or in the bottom.
• Two sensors: a temperature sensor and an oxygen sensor transmit information from the wood-
burning stove to the Air box.
• Room temperature sensor: The room temperature sensor with batteries communicates with the
HWAM®SmartControlTM via a wireless connection. It should be placed so it does not have direct
radiant heat from the stove. Note that the maximum distance between stove and room tempera-
ture indicator is about 4-5 metres. The range is reduced if there are walls or other obstructions
between the stove and the room temperature indicator.
• Electricity supply: from the Air box to the nearest wall socket.
• App "IHS Smart ControlTM:The app can be downloaded free from the App Store or Google Play
Store. See details in separate manuals for the app IHS Smart ControlTM or in the Quickguide.

InStAllAtIon
In general
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 instal-
lation, 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 management 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. 4-15 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 consider that the stove must be connected to power.

3. Distance to furnishings in front 80 cm
Remember to pay attention to 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®SmartControlTM..
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 stove requires a minimum draught of 12 Pa (measured at EN 13240 measurement point). If mea-
sured just above the smoke flue socket, the chimney draught must be 18-20 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 rear 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
insulation 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.
Vertical cross-section of the stoves (Drawing B):
• The top plate of the stove (1).
• Rear smoke outlet (3). At the factory this is sealed with a cover plate. The smoke outlet is therefore
hidden behind the plate.
• Top smoke outlet (4).
• The smoke shelf (5). To be placed on top of the steel rail and on the holders in the sides.
• Two-piece smoke defector plate (6). Each half is hung on the hooks located beneath the top plate. The
two halves join in the holders behind the air pipe. Once the stove has been installed, twist the protection
off the two hooks by using pliers or a screwdriver.
• Removable rear plate (2). This must always be mounted if the stove is placed next to a combustible
wall.
• Loose heat shield (8) under the ash pan. This can be used as a lid when the ash pan is removed for
emptying.
Connection of the HWAM®SmartControlTM
Before using the stove it must be connected to power. See the instructions in the separate manuals
for the app IHS SmartControlTM or in the Quickguide in order to connect to stove with the app and
the wireless room temperature sensor.
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 in the Air box for the so-called glass pane rinse which keeps the
glass free of soot, and 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 (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 and overheating, the HWAM®SmartControlTM will enter a security mode and
automatically adjust all dampers in the Air box, effectively quenching the fire. Do not open the door
for the burning chamber, since that might cause the fire to rekindle. Contact the fire brigade. After a
fire, the stove should be checked by a chimney sweep before use.
FIrIng MAnuAl - Wood
Your first heating session
The lacquer will be fully hardened after the stove has been used, and the door and the ash pan should
be opened very carefully as there will otherwise be a risk that the gaskets will stick to the lacquer.
In addition 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 12-18%. 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 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.

Page 14 of 20 pages
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) 25-30 2-5
Chopped wood 25-30 7-9
Lighting the stove
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.
Open the door. Place 2 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 2 firelighters between the top layer of
kindling. Light up the fire-lighters and close the door. Select the desired room
temperature level.
As soon as the door is opened the HWAM®SmartControlTM is activated. If lighting up does not occur
within 15 minutes, the HWAM®SmartControlTM will automatically go back to standby and the damp-
ers in the Air box will be closed.
If the smoke temperature does not reach a high enough level after lightning or stoking, the app IHS
Smart ControlTM and the wireless room temperature sensor emit a restoking alarm, even if there is
still unburned wood and flames in the combustion chamber. The restoking alarm is emitted to make
you aware that the fire needs more energy. Restoking with small pieces of kindling wood can often
provide a more rapid and sufficient temperature rise.
The HWAM
®
SmartControl
TM
closes all three air dampers in the Air box when the stove is in standby mode.
This prevents hot air from the room to enter the chimney (heat loss). This might on the other hand result in a
very cold chimney when the stove is lit. In certain cases it is necessary to assist the draught in the chimney by
opening the door to the burning chamber 3-5 minutes before lightning the stove. Read more on www.hwam.com
about the function of the chimney.
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®SmartControlTM 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!
The Thermostat Function
The HWAM®SmartControlTM will in general have an environmentally friendly combustion and adapt
to the desired room temperature. The thermostat function is designed as a radiator valve. The user
enters a desired heat level, which suits the room in which the stove is installed. When the thermostat
is set at a heat level, the control function will adapt to this temperature.
• If the room temperature is lower than the desired heat level, the HWAM®SmartControlTM increases
the flue gas temperature in order to increase the heat radiation from the stove.
• If the room temperature is higher than the desired heat level, the HWAM
®
SmartControl
TM
decreases
the flue gas temperature, thereby giving the layer of embers as long a life as possible before restok-
ing. This will reduce the heat radiation from the stove and facilitate restoking without having to

Page 15 of 20 pages
light up the fire anew. If the room temperature drops below the desired level, the ember phase
will be shortened, and the HWAM®SmartControlTM will activate a restoking alarm. The HWAM®
SmartControlTM will signal that a restoking is due at the flue gas temperature of 180° C, and at 100°
C the HWAM®SmartControlTM will enter standby mode and all dampers will close.
• Should the room temperature be much lower than the desired heat level, the HWAM®SmartControlTM
increases the flue gas temperature. If a satisfactory increase in temperature does not occur, the control
will activate a restoking alarm, since it expects that more wood is needed to increase the heat level in
the room.
• If the room temperature after a new restoking still does not reach the desired level, the water
content in the firewood may be too high or the draught in the chimney too weak. The HWAM®
SmartControlTM always strives for a sufficiently high flue gas temperature to ensure an environmen-
tally friendly combustion.
Stoking
When alarm for restoking sounds the stove is ready for restoking. The alarm for restoking will come via
the room temperature sensor or the acquired remote control. The app IHS Smart ControlTM will also
come with a notification that it is time for restoking if the app is opened. For more information on the
app, see details in separate manuals for the app IHS Smart ControlTM or in the Quickguide.
The amount of wood that is used for restoking should be adjusted based on the current heat demand.
In terms of combustion technique, you should always stoke the stove with at least two pieces of wood
at a time even if you only use a small amount of wood. You can also choose not to restoke. After a
while the stove will then automatically go in stand-by mode.
During combustion, the outer surfaces of the stove will become hot, and due care must
therefore be shown.
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 - HWAM 3130
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
possible. 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: 2.4 kg

Page 16 of 20 pages
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 glass may turn white, for example. If the flue gas
temperature exceeds 580oC, the HWAM®SmartControlTM will revert to safety adjustments and
automatically turn down the air valves to avoid overheating. When the temperature is reduced to
450oC, the normal functions apply again. The stove has been approved for intermittent use.
Typical re-firing interval
Typical re-firing interval at nominal performance
Wood: 45 min (0,89 kg)
Prolonged burning time
You achieve the slowest combustion by setting the desired room temperature at level 0. At this level
the combustion takes place with the lowest possible flue gas temperature and the ember phase will
be drawn out as long as possible.
How to achieve the best combustion
The HWAM®SmartControlTM is purposely designed to generate the cleanest and the most economical
combustion. A good combustion is achieved when the fire gets the right amount of oxygen supply at
the right time and place in the combustion chamber. The HWAM®SmartControlTM allows for varia-
tions in external circumstances. Nevertheless, it is important to use clean and dry wood (humidity
approx. 12-18%). Read more on www.hwam.com.
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 F. 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 gaskets. Replace gaskets if they are not intact or have softened.
• Checking of heat insulating material and possibly replacement.
• Checking of the bottom/shaking grate.
• Lubricating the hinges and the locking hook with cobber grease (drawing F).
All service checks must be performed by an authorised fitter. Use only original spare parts.
Inside cleaning
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 D).
• First lift the smoke shelf (1) out of the steel rail (2) at the back of the combustion chamber. Next,
lower it beneath the holders (3) and slide it out.

Page 17 of 20 pages
• Lift each half of the steel smoke plate (4) off the holder (5) behind the smoke pipe, and remove them
from the hook (6) beneath the top plate.
Ashes
The ash pan is best emptied by pulling a waste bag over the pan, tipping it and then carefully pulling it
out of 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.
Door/glass
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!
Maintenance Alarms
If a maintenance alarm goes off, you can continue using the wood-burning stove, but contact your
retailer as soon as possible. Your stove could be affected by impure combustion.
