Maintenance
Regularly ensure that the air slit for the pane air rinse function (drawing C, 3) is free of ash and soot
particles. Regularly check to make sure that seals in the door are complete and soft. If not, they should
be replaced. Use only original spare parts.
The insert should be thoroughly cleaned once a year. Ash and soot must be removed from the combus-
tion chamber. If necessary, lubricate the door lift mechanism with copper grease.
Service inspection
At least once every other year, the insert should receive a thorough, preventative service inspection.
Among other things, the service inspection covers:
• A thorough cleaning of the insert.
• Inspection of the door lift mechanism and lubrication with copper grease if necessary
(drawing B,1) .
• Check the spring in the HWAM
®
Autopilot™ and replace if necessary.
• Checking gaskets. Replace gaskets if they are not intact or are no longer soft.
• Inspection of springs for chain drive. Inspection to ensure that the chain drive is equal on both sides,
and that the door closes tightly all the way around.
• Inspection/possible replacement of heat insulation material.
The inspection must be performed by a qualified professional. Use only original spare
parts.
Cleaning
Before chimney sweeping can be performed, the air control lever must be set all the way to the left to
prevent soot and ash from entering the HWAM
® Autopilot™. Drawing C:
Remove the smoke shelf (1) . Push the plate forward and lift it up a bit to the side. Tilt one side downward.
The plate is now free and can be removed from the combustion chamber. Lift the steel smoke deflector
plate
(2) off of the hooks so that it can be removed.
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
