reduces the burning time.
With both regulating rods (1 and 2) in the middle position, the highest efficiency is achieved. Postpone
every new firing till the ember is suitably low.
Firing with coal, briquettes and coke
When firing with coal or coke, a coal insert must be used. Place fuel in the insert (the briquettes on the
wood embers). Close right regulating rod (2) completely and open temperature control (1) fully, until the
fuel is glowing well. Remember that the temperature control (the left regulation rod) must
be re-closed after this. Be aware that using fuels other than wood, will cause soot to form
on the glass pane.
Firing in general
Quick or strong heat is obtained by burning many small pieces of wood.
Maximum amounts of fuel
The stove is intended for a maximum hourly burning of the following max. amounts of fuel:
• 2.4 kg wood • 1.3 kg coal • 1.6 kg briquettes or • 0.9 kg coke
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.
Prolonged burning time
Prolong the burning time by burning a few (at least 2) very large pieces of wood whilst at the same time
closing the temperature controls down. To extend burning time, the sliding damper in the door should
be regulated down to the half open position. Shutting the damper down further may result in the glass
sooting up.
Insufficient firing
If the fireproof materials in the combustion chamber are blackened after a heating session, the stove is
polluting, and the automatic air flow regulation system is not functioning properly. It will be necessary,
therefore, to open the temperature control and, possibly, also to open the sliding damper in the door.
Also, it may be necessary to burn more wood.
Cleaning the glass
We recommend wiping the glass after a heating session. This is best done using paper towel.
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.
Briquettes give off a lot of heat. Certain types expand considerably, thus causing an uncontrollable com-
bustion.
Coal burns at a high temperature and makes a lot of soot. Coal must be burned using the coal insert.
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, reduces the life
of the stove and chimney considerably.
The stove is EN-approved for the firing of wood only. No particle board, lacquered, painted
or treated wood, plastics, or rubber may be used.
