HWAM Autopilot iHS™
Congratulations on your new wood-burning stove complete with a HWAM Autopilot IHSTM
IHS is short for “Intelligent Heat System”, which is a digital control of the combustion in your new
wood-burning stove. The purpose of the HWAM Autopilot IHSTM is to control the combustion in an
environmentally optimal and economically efficient way, with a view to generating greater user comfort.
The HWAMAutopilot IHSTM is a completely 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.
Via a simple remote control,the user can adjust the thermostat to the desired heat level,while continually
receiving information about room temperature and optimal stoking times that ensure environmentally
friendly and economical combustion.
Your new wood-burning stove and the HWAMAutopilot IHS
TM
will ensure the cleanest possible combus-
tion 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.

General information
Installation of your HWAM woodburning stove must always comply with local building regulations. It is
a good idea to consult your local chimney sweep before installing, since he will be the one to sweep the
chimney and stove.
Always follow the instructions of the manual carefully and make sure that the installation is carried out
by a qualified professional. HWAM packaging material should always be handled in accordance with the
local rules for waste handling.
Room requirements
There must be a constant supply of fresh air to the room in which the stove is to be installed. The
woodburning stove uses approx. 13-17 m3air per hour. In comparison, a modern cooker hood sucks up
to 1000m3air per hour.A window that opens or an adjustable air vent should be sufficient, but it is also
possibletoconnectthestovetoaHWAMfreshairsystem.Theairinlet/gratingmustbeplacedsothat
they do not become blocked.
Technical data
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.Weightofthestove:

Please be aware that not all glass parts are heat-resistant. For this reason, a glass wall should sometimes
be treated as a flammable 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.
Remember to pay attention to any 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 IHSTM.
Requirements for chimney and smoke pipe
The chimney must be of a sufficient height to enable an adequate draft and to prevent smoke problems.The
stove requires a draft of at least 12 Pa.
The chimney must have a minimum opening equivalent to Ø 15 cm.The chimney opening should always
be at least the size of the outlet socket of the stove.The chimney must have an easily accessible soot door.
Smoke pipe and chimney must always be suitable for a stove connection.Ask your HWAM dealer for
more information.
Fitting the loose parts
Before the stove is installed, you must ensure that all loose parts are fitted correctly.
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

Connecting and preparing the HWAM Autopilot IHSTM
1. Connect the plug
a) to a normal 230V socket
b) to the Air box in the wood section underneath the combustion chamber (lead the plug through
the air slot at the bottom between the side and rear plates - on the left side of the wood-burning
stove when seen from the front.There is a mark on the Air box where the plug should be let in. See
the photo of the power supply on the Air box.
Air box withour power supply. Air box with power supply.
2. Insert three AA batteries in the remote control.When the IHS logo disappears from the display, the
remote control is ready to use.
3. The remote control and the wood-burning stove must be connected (the factory will see to this).
If the status line at the bottom of the display is clear (empty) ( )and divided
into three sections, the wood-burning stove and the remote control are connected.
If the status line is dotted ( ),the remote control and the wood-burning stove
are not connected. Start with a display in which the light is off, and make the connection by pressing
and holding down the button, so the advanced menu is displayed.Then press the button repeatedly in
short intervals until the text ”Link to stove” is highlighted and wait until it enters this menu. Press the
button in short intervals until the text “Connect” is highlighted and wait again.When the text "Please
cycle stove power" appears on the display,disconnect the electricity from theAir box and then recon-
nect. Press the button once more. If the message "Connected to stove" shows up in the display, the
wood-burning stove and the remote control are connected. Press the button once to return to the
main menu. If you do not press the button again, the remote control automatically leaves the menu
and returns to the start display.

4. Go through the self-test of the HWAM Autopilot IHSTM:
The self-test of the electronic control is carried out before lighting the first fire in the stove (the
factory will see to this).The self-test can only be done when the wood-burning stove is cold and in
standby mode (no signal in the status line ). Make sure that the display is
not active, i.e. there should be no light in the display ( ). If there is light in the
display before you hold down the button for a while, you will instead prepare the wood-burning stove
for lighting (the matchbox will appear in the display) and no self-test can be carried out.
Press the remote control button for approx. 5 seconds in order to enter the menu. Press the button
until the cursor reaches “Self-test”.Wait a few seconds till the remote control enters the “Self-test”
menu. Press the button till the cursor reaches “Engage”.A few seconds later the self-test begins.
By going through a self-test you ensure that all basic operations function correctly.
 Aself-testconsistsoffourtesttypes:
 •Asoftwaretest
 •Atestofthetemperaturesensorandcalibration
 •Atestofthelambdasensorandcalibration
 •Atestofthethreemotorvalvesandcalibration
The remote control will respond with the text ”Pass” if everything is OK or ”Failed” if there is a
problem.The remote control will also respond with the text "Failed" if you, prior to self-test with the
remote control, have prepared the wood-burning stove for lighting up a fire (made the match box
appear on the display). If the electric power is cut and switched on again, the programme will return
to standby and the self-test can be carried out. If the remote control responds with the text "Not
completed", the self-test could not be carried out, either because the wood-burning stove has not
cooled off or because it is not in standby mode.
5. The remote control must be placed in the same room as the wood-burning stove and in a location
where it is neither exposed to direct heat radiation from the stove nor to direct sunlight.The reason
is that the remote control functions as a thermometer.The room temperature is transmitted wirelessly
to the stove’s electronic control to support the intelligent regulation of the combustion.The remote
control stand can be mounted on the wall.
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.The partial vacuum removes the smoke from
the stove, sucks air through the damper to the so-called pane flush mechanism, which keeps the window
pane soot free, and sucks air into the combustion via the HWAM Autopilot IHSTM.
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.
Even a good chimney can function badly if it is not used correctly. Similarly, a bad chimney may function
well if used correctly.
Chimney sweeping
To prevent the risk of chimney fires,the chimney must be cleaned every year.The flue duct and the smoke

13
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 Autopilot IHSTM will enter a security mode and
automatically adjust all dampers, effectively quenching the fire. Do not open the stove door, 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.
tHE REMotE contRol
The remote control is the user interface of the HWAM Autopilot IHSTM.The remote control measures
the actual room temperature. It must hence be placed in a location in the room, where it is not affected
by unnaturally high temperatures, such as the wood-burning stove’s radiation heat or direct sunlight.
On the remote control you enter the desired heat level, as you would on a radiator thermostat.Via radio
waves the remote control sends information to the stove’s Air box (control system) about the present
room temperature as well as the desired heat level.
Below you will find the functions of the remote control.As a point of departure, the normal display image

Thermostat adjustment
The HWAM Autopilot IHSTM has a thermostat function, which attempts to keep
the room temperature at the desired level.The thermostat works like a radiator.
Use the remote control to choose the level you want and the temperature that
suits your rooms.
Thethermostatfunctioncanbeadjustedtosixdifferentlevels:
(Level 0 - 5, where level 3 is a medium temperature of approx. 22-24° C).
Level0:regulatestotheslowestcombustion(3-4kW)noroomtemperaturecontrol.

Level5:regulatestothemaximumroomtemperature(approx.27-29°C).Thislevel
aims to reach the highest possible room temperature in the shortest possible time.
This choice can be an advantage if you want to heat up an unheated room as quickly
as possible.When the temperature in the room approaches the desired level, the
desired heat level is entered on the remote control.
The Status Line
The status line appears at the bottom of the display.It shows where in the combus-
tion the system is located.
Not in contact with the Air box.
In contact – but in standby mode.
The initial phase of the combustion.
The process phase of the combustion.
The burning out phase of the combustion.
Ligthing the fire:
The woodburning stove is ready to be lit and opens the dampers.The symbol appears
when you press the remote control twice in either standby or burning out modes.
The symbol is also shown if you press the remote control twice in the burning out
phase. In this case it does not mean that you need to light up again.This is merely
information that you have asked the stove to open the dampers and thereby ensure
that the new firewood gets sufficient air to catch fire.

15
The restoking alarm
When the combustion progresses to the ember phase,a restoking alarm will go off.
The alarm will light up three times with a ten second interval and it is supported
by sound.
Threedifferentamountsofwoodarerecommendedforrestoking:
A small amount of wood (700 - 1200 g)
A medium amount of wood (1000 - 2000 g)
A large amount of wood (1800 - 3000 g)
You must use at least two pieces of firewood at a time, even if you only want to use
a small amount of wood.The temperature causes the wood to gasify.Two pieces of
firewood heat up each other and increase their temperature faster.
A reminder of the restoking alarm
If a restoking alarm has gone off,and no restoking has been carried out,this symbol
will flash on and off in the upper left corner.
If the symbol has been displayed for a long time, the temperature in the flue gasses
can be so low that you have to light up again in order to give the stove more air
(this is done by pressing the remote control twice, causing the lighting up symbol
to appear in the display).
Always be aware that the status line changes from the burning out phase to the
combustion process phase when the stove is relit.Thereby you ensure that the
stove has registered that you have added new firewood which requires an adequate
amount of air.The oxygen level in the combustion compartment increases when
the door is opened.This sends a signal to the stove that new firewood has been
added to the fire.Towards the end of the burning out phase,the oxygen level in the
combustion compartment can be so close to the oxygen level in the room that the
increase in the oxygen level in the combustion compartment due to the opening
of the door cannot be registered. If, shortly after relighting,the status line does not
alter from burning out phase to combustion process phase, you should press the
remote control twice until the lighting up symbol (the matchbox) appears.
Updating
When the Air box is updated with new software (by a service technician), this will
be displayed graphically.
Advanced menu
The remote control has a menu in which more advanced settings,etc.can be changed.
By pressing the button on the remote control for more than five seconds, you get

Information about removal and recycling
The remote control contains batteries and must hence be disposed of separately in accordance with the
national rules and regulations in force.
Regulatory compliance information
ComplieswiththerequirementsintheEuropeanDirectives72/23/EECand2004/108/EEC.
FiRing MAnuAl - Wood
When you light the stove for the first time it should not be stoked excessively as all the materials must be
given time to adapt to the effects of heat.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 gas-
kets 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.The operating handles are located behind the extension beneath the door.
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 20%. 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
wood burning stove.The great difference is not in the fuel value, but in the weight of the wood types per
cubic metre.Since beech weighs more per cubic metre than for instance common spruce,it will take more
common spruce to produce the same amount of heat that you would get from a cubic metre of beech.
Banned fuel types
Itisnotallowedtostokearewiththefollowing:printedmatter,plywood,plastic,rubber,uidfuels,
and rubbish such as milk cartons, lacquered wood or impregnated wood or 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
The wood’s water content of a maximum of 20% is reached by storing the wood for a minimum of one
year, preferably outdoors in an open shed exposed to sun and wind.
The wood must be dry (max. 20% water contents) before it is stored indoors. It is recommended that
kindling wood is stored indoors for a couple of days prior to use.

Special lighting guide for wood-burning stoves with soapstone cladding
Soapstone is a natural product, which needs to get used to the changes in temperature. For this reason
you should be very careful the first times you light up the stove. It is recommended that you follow the
procedureoutlinedbelow:
1.The first stoking (soapstone)
Place split kindling with a diameter of 2-5 cm the equivalent of approx. two pieces of wood (a maximum
of two kilos) in the stove. Place two fire-lighters in between the top layers of kindling. Press the remote
control twice to activate the symbol of lighting up. Light up the fire-lighters and close the stove door.
Adjust the temperature selection mechanism on the remote control to level one. 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 (soapstone)
Place split kindling with a diameter of 2-5 cm the equivalent of approx. two pieces of wood (a maximum
of two kilos) in the stove. Place two fire-lighters in between the top layers of kindling. Press the remote
control twice to activate the symbol of lighting up. Light up the fire-lighters and close the stove door.
Adjust the temperature selection mechanism on the remote control to level two.When there is a restok-
ing alarm, you should restoke. Fill the combustion chamber half way up with dry wood of a diameter of
approx.7-9 cm.Let the fire burn and let the stove cool down to room temperature before the next lighting.
3.The third stoking (soapstone)
Repeatthesecondstoking,butusemorewoodthistimeandadjustthetemperatureselectiononthe
remote control to level three.Let the fire burn and allow the stove to cool down after the fire has died out.
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. It is important to achieve a high flue gas temperature quickly.
Only at temperatures around 350° C will environmentally friendly combustion take place.
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. Press the remote control
twice to activate the symbol of lighting up. Light up the fire-lighters and close the
stove door.Adjust the temperature selection mechanism on the remote control
to the desired heat level.
If the desired flue gas temperature of 350° C has not been achieved within 15 minutes,the remote control
will activate a re-stoking alarm even if there still might be wood and flames in the combustion compart-
ment.The re-stoking alarm can seem misplaced, but it is activated because the temperature climbs too
slowly.Re-stokingwithsmallpiecesofkindlingwoodcanoftenresultinafasterincreaseintemperature.
HWAM Autopilot IHSTM closes all three air dampers 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

Important!
The ashpan must not be opened when lighting up. It must always be closed when the stove is in use.
Otherwise the stove’s intelligent control system does not function.The door should only be opened when
lighting up, when restoking, and when cleaning the stove.
The Thermostat Function
The HWAM Autopilot IHSTM 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.

gas temperature, thereby giving the layer of embers as long a life as possible before re-stoking.This will
reduce the heat radiation from the stove and facilitate re-stoking without having to light up the fire
anew. If the room temperature drops below the desired level, the ember phase will be shortened, and
the system will activate a re-stoking alarm.The system will signal that a re-stoking is due at the flue gas
temperature of 180° C, and at 100° C the system will enter standby mode and all dampers will close.
• Shouldtheroomtemperaturebemuchlowerthanthedesiredheatlevel,thecontrolfunctionincreases
the flue gas temperature. If a satisfactory increase in temperature does not occur, the control will
activate a re-stoking alarm,since it expects that more wood is needed to increase the heat level in the
room.

in the firewood may be too high or the draught in the chimney too weak. For environmental reasons
the recommended flue gas temperature should always be a min. of 350° C.
Stoking
When the stoking alarm on the remote control sounds,the stove is ready for stoking.The remote control
will recommend the amount of wood you should use.
Small amount of wood Medium amount of wood Large amount of wood
(700 - 1200 g) (1000 - 2000 g) (1800 - 3000 g)
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 into hibernation.
In exceptional cases the system might not register that the stove has been re-stoked.This can occur if
the oxygen level in the combustion compartment, due to the low flue gas temperature, reaches a point
where the system fails to register an increase in the oxygen level in spite of the stove door having been
opened.After stoking, the status line should therefore be checked on the remote control. Shortly after
the lighting of the wood,the middle section of the remote control, representing the combustion process
phase, should light up. ( ) If it enters standby mode, press the remote control
twice, so the match symbol is displayed.
During combustion, the outer surfaces of the stove will become hot, and due care must
therefore be shown.
Firing with coal, briquettes and coke
Burning coal and coke is not possible in this stove since there is no room for a coal insert. Briquettes can
be used however.These are placed onto the wood embers. Remember that after this the regulat-
ing rod must be closed again. Be aware that using fuels other than wood, will cause soot to
form on the glass pane.

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 soapstone interior of the heat compartment as rapidly as possible.
Keeping the convection damper closed retains the heat stored in the soapstone as long as possible.When
the damper is opened, the heat from the soapstone in the heat compartment will rapidly be transferred
to the room.

Long burning times
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 Autopilot IHSTM 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 Autopilot IHSTM allows for variations
in external circumstances. Nevertheless, it is important to use clean and dry wood (humidity approx.
16-20%).Readmoreonwww.hwam.com.
Cleaning the glass
We recommend wiping the glass after a fire.This is best done using a paper towel.
Types of fuel
The stove may be damaged by very high temperatures and the glass may turn white,for example.This can
be avoided by never allowing the stove to burn with the ashpan open and taking great care with types
of fuel that develop excessive heat, such as briquettes. If the flue gas temperature exceeds 580oC, the
HWAM Autopilot IHSTM 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.
It is recommended that you use birch or beech wood that has been chopped and stored for at least one
year in an open shed exposed to sun and wind.The wood must be dry (max.20% water contents) before it
is stored indoors.It is recommended that kindling wood is stored indoors for a couple of days prior to use.

Briquettes give off a lot of heat. Certain types expand considerably, thus causing an uncontrollable com-
bustion.
Coal burns at a high temperature and makes a lot of soot. Coal must be burned using the coal insert.
Not suitable for fuel in these models.
Coke burns at a high temperature and makes a lot of soot. Coke must be burned using the coal insert.
Coke causes severe wear and tear to stove and combustion chamber and,consequently,this considerably
reduces the life expectancy of the stove and chimney.
Not suitable for fuel in these models.
The stove is EN 13240 approved for firing wood only. No particle board, lacquered, painted
or treated wood, plastics, or rubber may be burned.

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 G. Lift the door approx. ½ cm and spray copper fat onto the hinge leaf.

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,become worn and damaged.
