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 HWAM Autopilot 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 HWAM Autopilot IHSTM 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 Autopilot IHSTM consists of the following components:
• Airbox:theAirboxcontainsaprintedcircuitboard/software,aswellasthreemotorsthatcontrol
primary, secondary, and tertiary combustion air. The fresh air system can be mounted on the Air
box to the rear or in the bottom.

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. 11-14 m3air per hour. In comparison, a modern cooker hood sucks
up to 1000m3 air 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combustionairsystem.Theairinlet/gratingmust
be placed so that they do not become blocked.
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.
Load-bearing capacity of floor
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 any regulations concerning the required distance between
the wall and smoke pipe.
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 150 mm. The chimney opening should
always be at least the size of the outlet socket of the stove. The chimney must have an easily acces-
sible soot door.
Smoke pipe and chimney must always be suitable for a stove connection. Ask your HWAM dealer for
more 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.

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 without 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
the Air box and then reconnect. 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.

14
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 (4). 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.
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.

15
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 func-
tion 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 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 IHS
TM
. 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

Room Temperature
The room temperature is shown in the centre of the display. The room tem-
perature is measured in the location of the remote control. The actual room
temperature is used both when controlling the combustion and in connection
with the timing of the re-stoking alarm. The remote control should hence not
be placed close to the stove or in direct sunlight, since it will be affected by
unnaturally high heat levels.
Battery level
The battery level of the remote control. When the batteries are at a minimum
level, they need to be changed. Expected battery life at normal use is approxi-
mately ½-1 year.
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.

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.
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.
Areminder 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.

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 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amaximumof20%.Stokingare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.

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

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.

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
compartment. The re-stoking alarm can seem misplaced, but it is activated because the 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.

flue 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

content 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.
