HWAM® SMArtControl™
Congratulations on your new wood-burning stove complete with a HWAM®SmartControlTM
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 com-
bustion 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 temperature
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 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. 7-21 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.

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®SmartControl™.
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 measured
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 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.

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 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 12-18%. Stoking a fire with wet wood results in soot, environ-
mental 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.
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:

Page 14 of 20 pages
1.The first stoking
Open the door. Place two pieces of wood (5-8 cm in diameter) horizontally in the
bottom of the combustion compartment. Place 5-8 pieces of kindling randomly
on top. Place two firelighters in between the top layers of kindling. Light up the
firelighters and close the stove door. Set the temperature level to level 1. Let the
fire burn out and do not restoke even if there is a restoking alarm.When the fire
has died out completely, the door must be opened and stay open while the stove
cools down to room temperature.
2.The Second Stoking
Open the door. Place two pieces of wood (5-8 cm in diameter) horizontally in the bottom of the com-
bustion compartment. Place 5-8 pieces of kindling randomly on top. Place two firelighters in between
the top layers of kindling. Light up the fire-lighters and close the stove door. Set the temperature level
to level 2. When there is a restoking alarm, you should restoke. Put at least two pieces of wood into
the stove, weighing up to 1 kg each. Let the fire burn and let the stove cool down to room temperature
before the next lighting.
3.The Third Stoking
Repeat the second stoking. Set the temperature level to level 3. Let the fire burn and allow the stove to
cool down after the fire has died out.
Restoking:
Follow the general instructions, see the sections “Lighting up” and “Stoking”.
Lighting Up
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 two pieces of wood (5-8 cm in diameter) horizontally in the
bottom of the combustion compartment. Place 5-8 pieces of kindling randomly
on top. Place two fire-lighters in between the top layers of kindling. Light up the
fire-lighters and close the stove 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 dampers
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!

Page 15 of 20 pages
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®SmartControlTM decreases
the flue gas temperature, thereby giving the layer of embers as long a life as possible before restoking.
This will reduce the heat radiation from the stove and facilitate restoking without having to light up
the fire anew. If the room temperature drops below the desired level, the ember phase will be short-
ened, 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
®
SmartControl
TM
always strives for a sufficiently high flue gas temperature to ensure an environmentally friendly combus-
tion.
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.
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: 3.1 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 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

Typical re-firing interval at nominal performance
Wood: 45 min (1,18 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 variations
in external circumstances. Nevertheless, it is important to use clean and dry wood (humidity approx.
12-18%). Read more on www.hwam.com.

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
degrees Celsius), 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 are no longer soft.
• Checking and/or replacing insulation material.
• Checking the construction (only some countries).
• Checking the bottom and/or shaking grate.
• Use copper grease for hinges and locking hooks (see 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):
• 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.
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.

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.

moisture level not exceeding 12-18 % RH.
• Faulty seal in door. Fit new seal.
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.
Uncontrollable combustion
• Faulty seal in door or ash pan. Fit new seal.
Safety Alarms
In case the safety alarms go off, you must not use the stove. Contact your retailer as soon as possible.
At interruptions that you cannot yourself rectify, you should contact the retailer.
