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 ow 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.
To store heat in the heat storage stones in the heat storage compartment as quickly as possible, it is
recommended that the convection vent be kept closed while the re is lit.
With the convection vent closed, the heat storage compartment retains the heat stored in the heat stor
-
age stones for the longest possible duration. If the vent is opened, the heat stored in the stones in the
heat storage compartment will be released into the room as quickly as possible.
Firing in gEnErAl
Rapid or erce heat
Rapid or erce 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 stove has been approved for intermittent use.
Typical re-ring interval
Typical re-ring interval at nominal performance
Wood: 45 min (1.8 kg wood)
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 ue gas temperature and the ember phase will be
drawn out as long as possible.
How to achieve the best combustion
The HWAM Autopilot IHS
TM
is purposely designed to generate the cleanest and the most economical
combustion. A good combustion is achieved when the re gets the right amount of oxygen supply at
the right time and place in the combustion chamber. The HWAM Autopilot IHS
TM
allows for variations
in external circumstances. Nevertheless, it is important to use clean and dry wood (humidity approx.
16-18%). Read more on www.hwam.com.
Cleaning the glass
We recommend wiping the glass after a re. 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 ue gas temperature
exceeds 580
o
C, the HWAM Autopilot IHS
TM
will revert to safety adjustments and automatically turn
down the air valves to avoid overheating. When the temperature is reduced to 450
o
C, 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. 18% water contents)
