Insulation
In time, the combustion chamber's efficient but porous insulation may become worn and damaged.
Cracks in the rear plate could result in the secondary air being distributed incorrectly inside the
combustion chamber, and the plate should therefore be replaced. Cracks in any of the side plates have
no bearing on the efficiency of the stove.
However, the side plates and smoke shelf should be replaced if the wear exceeds half of the original
thickness.

Lift off the rear panel. On a cold stove, the starting point of the feeler is controlled. The starting point
on a cold stove is about 10º above horizontal.
It should feel easy going and bouncy when you push it, no matter if the stove is cold or hot. By rising or
falling temperatures it must not move at a bound. The damper plates must be dry and clean and slide
together unhindered. Control bars and slide gates may have to be smeared with WD40 (never oil).
Door/glass
Check that the air ducts in the doorframe are free from ash and soot particles.
If the glass has become sooted up, it may be cleaned with a slightly moist piece of paper dipped in
ashes. Regularly check that the door gaskets are intact and flexible. If not, they should be replaced.
Use only original gaskets.
Once a year, ensure that the glass has not moved sideways. The glass is fastened to the door as tightly
as possible before leaving the factory, but not so tight as to cause the glass to burst as a result of
temperature fluctuations.
The glass can be pushed back into the middle of the wood-burning stove by carefully loosening the
two clips that hold it in place on the door.
Door lift, drawing F
The door lift mechanism consists of a chain pull placed on either side of the stove and a spring. If the
door opens with difficulty, you may correct this by greasing the chain wheel boxes (1) and door hinges
(2) with copper grease (we recommend a grease that can withstand temperatures of up to 1,100º C) .
You should do this once every year. If the door still opens and closes too stiffly, the spring on the door
lift mechanism can be loosened slightly. If the door slides too easily, the spring has loosened.
The spring can be loosened or tightened as follows:
Remove the loose side plate on the left side of the stove (seen from the front) by lifting it up and out
to the side. Make sure the door of the combustion chamber (3) is closed. Attach the tightening tool (4)
supplied with the stove to the toothed wheel (5). To tighten the spring so that the door closes more
slowly (or can remain fully open), turn the toothed wheel (5) clockwise slightly. This can be done by
turning the tightening tool (4) counter-clockwise. To loosen the spring so that the door closes faster
(or can no longer remain fully open), lift the locking pawl (6) and turn the toothed wheel (5) counter-
clockwise slightly. This can be done by turning the tightening tool (4) clockwise. IMPORTANT! Keep a
firm grip on the handle of the tightening tool (4) when lifting the locking pawl as considerable weight
and force are transferred when it is lifted.
After each adjustment, check to see whether the desired effect has been achieved. If not, repeat the
process. If you have loosened the spring, we recommend holding the door handle when checking the
effect for the first time to ensure that the spring has not become so loose that the door closes too
fast with the risk of damaging the glass.
Please Note: You should always have a professional adjust, grease and repair these parts.
