IrIng In general
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 3.5 kg
Warning: Should these limits be exceeded, the insert will no longer be covered by the factory guarantee,
and it may be damaged due to excessive heat. The insert has been approved for intermittent use.
Normal re-firing interval for nominal firing
Fuel Kg Normal Firing Interval
Wood Ca. 1.54 48 min
Prolonged burning time
Prolong the burning time by burning a few (at least 2) very large pieces wood whilst at the same time
regulating the damper down.
Insufficient firing
If the fireproof materials in the combustion chamber are blackened after a heating session, the insert is
polluting, and thHWAM
®
Autopilot™ is not functioning properly. The bar must therefore be pushed to
the right. Also, it may be necessary to burn more wood.
How to achieve the best combustion
• Use clean and dry wood.
Wet wood results in inefficient combustion, plenty of smoke, and soot. Furthermore, the heat will dry
the wood, not heat up the room.
• The fire should only be stoked with a little wood at a time.
You achieve the best combustion by starting up a fire often and using only a little wood. If you use too
much firewood, it will take some time before the temperature reaches a level where you achieve a
good combustion.
• Make sure there is the right amount of air.
You should also make sure that there is plenty of air – especially in the beginning - so the temperature
in the insert climbs quickly. In this way the gasses and particles released during the combustion will be
consumed by the fire. Otherwise they build up soot in the chimney (constituting a chimney fire risk)
or will be released in a non-combusted state into the environment. The wrong amount of air supply
creates inefficient combustion and a modest effect.
• Don’t savour the fire during night time
We advise against adding fire wood to your insert and reducing the air supply at night in an attempt to
still have some embers left in the morning. If you do so, large amounts of hazardous smoke will be emitted,
and your chimney will be exposed to unnecessarily large amounts of soot with the risk of a chimney fire.
