Normal re-firing interval for nominal firing
Fuel
Wood
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 the automatic air flow regulation system 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 stove 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 .
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 door open and taking great care with types
of fuel that develop excessive heat, such as briquettes .
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 .
Briquettes give off a lot of heat . Certain types expand considerably, thus causing an uncontrollable combustion .
Coal burns at a high temperature and makes a lot of soot .
Coal must be burned using the coal insert .
Not suitable for fuel in these models.
Coke burns at a high temperature and makes a lot of soot . Coke must be burned using the coal insert .
Coke causes severe wear and tear to stove and combustion chamber and, consequently, this considerably
reduces the life expectancy of the stove and chimney .
Not suitable for fuel in these models.
