Insulation
The efficient, but porous insulation of the combustion chamber may, in time, be worn and damaged. Cracks
in the insulation are irrelevant to the efficiency of the stove. However, it should be replaced, if there are
actual holes due to parts of the lining falling off or when, due to wear and tear, it has been reduced to
less than half its original thickness.

Autopilot™
On a cold stove, the starting point of the feeler is controlled. The starting point on a cold stove is about
30° 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 lift (Drawing B)
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 and door hinges (1)
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 insert from the outer casing. 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.
Surface
The surface does not normally require any treatment. Any damage to the coating may be remedied using
a Senotherm spray.
