Chimney
The chimney is the “motor” of the stove and it is crucial for the functioning of the stove. The chimney draft provides a partial vacuum in the stove.
This vacuum removes the smoke from the stove, sucks air through the dampers for the so-called glass pane rinse which keeps the glass free of
soot, and sucks air into the combustion via the HWAM
®
SmartControl
TM
.
The chimney draft is created by the differences in temperature inside and outside the chimney. The higher the temperature within the chimney,
the better the draft (a brick chimney takes longer to warm through 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. Contact your local
chimney sweeper for the approval of your chimney.
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
®
SmartControl
TM
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.
Quick or strong heat
Quick or strong heat is obtained by burning many small pieces of wood.
Maximum firing amount
Fuel Maximum amount per hour
Wood 2.5 kg
Warning: Should these limits be exceeded, the stove will no longer be covered by the factory guarantee, and it may be damaged due to excessive
heat. The stove has been approved for intermittent use.
Normal re-firing interval for nominal firing
Fuel Kg Normal firing interval
Wood Ca. 1.8 65 min
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
HWAM
®
SmartControl
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. HWAM ® SmartControl TM allows for
variations in external circumstances. Nevertheless, it is important to use clean and dry wood (humidity approx. 12-18%). Read more on www.

Types of fuel
We recommend using birch or beechwood, which has been split and stored for at least one year outdoors under cover. Wood stored indoors
tends to become too dry and burn too quickly. It is recommended that kindling wood is stored indoors for a couple of days prior to use.
The stove may be damaged by very high temperatures and the glass may turn white, for example. This can be avoided by 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 ® SmartControl 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.
