Skamol Refractory
The effi cient, but porous Skamol refractory in the combustion chamber may, in time, be worn and
damaged. Cracks in the Skamol will not affect the operation of the insert. However, the Skamol should
be replaced when, due to wear and tear, it has been reduced to less than half its original thickness.
Automatic Control System
The control arm starting point on a cold insert is about
75° above horizontal. It should feel easy going and
bouncy when you push it. The damper plates must be
dry and clean and slide together unhindered. Control
bars and slide gates may be lubricated with WD40
(never oil).
Adjust the Lifting Door for Model 04111
The door lift mechanism consists
of a chain pull placed on either
side of the insert 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 2 years. 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:
Slide the inner cassette out of the
outer case. Make sure the door
of the combustion chamber (3) is
closed. Attach the tightening tool
(4) supplied with the insert 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
