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:
Model Wood
HWAM 4500 2.4 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-firing interval
Typical re-firing interval at nominal performance:
Model Re-firing interval Wood
HWAM 4500 45 min. 1.1 kg
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 IHS
TM 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 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 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 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)
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.
The stove is EN 13240 approved for firing wood only. No particle board, lacquered, painted
or treated wood, plastics, or rubber may be burned.
