Service inspection
Your stove should be given a thorough, preventive inspection once every two years. This includes:
• Thorough cleaning of the stove.
• Checking the spring in the Autopilot unit. Replace if necessary.
• Checking gaskets. Replace gaskets if they are not intact or are no longer soft.
• Checking and/or replacing insulation material.
• Checking the combustion chamber base.
• Use copper grease for hinges and locking hooks (see drawing I).
All service checks must be performed by an authorised tter. Use only original spare parts.
Inside cleaning
Before chimney sweeping can be performed, the regulator must be set to its minimum position to prevent
soot and ash from entering the Autopilot control.
Remove the top smoke shelf and the two-part steel smoke guide plate from the stove before cleaning.

• Lift the smoke shelf (1) out of the combustion chamber.
• Unhook each half of the smoke guide plate (2) from the hook (3) under the top plate.
Ashes
It is easiest to empty the ash pan by pulling a plastic bag over it, turning it upside down and then carefully
removing it from the bag. Ashes are disposed of via the domestic waste collection.
Please note that there may be embers in the ashes for up to 24 hours after the re has
gone out!
Insulation
The efcient, but porous insulation of the combustion chamber may, in time, become worn and damaged.
Cracks in the insulation have no effect on the efciency of the stove. The insulation should be replaced,
however, when it is reduced to less than half the original thickness due to wear and tear.
HWAM Autopilot™ (Drawing G)
Lift the top plate off the stove. Remove the rear plate by loosening the two screws. On a cold stove,
the starting point of the feeler is controlled. The starting point for a cold stove is approx. 10° above
horizontal (at laser cut mark).
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
A sooty glass door can easily be cleaned with a piece of moist kitchen roll dipped in ash. Go about it in
vertical movements (up and down). Follow up with a dry piece of kitchen roll. Check frequently to ensure
that seals in the door are intact and not brittle. Failing this, they should be replaced. Use original seals only.
Surface
The surface normally requires no treatment. Any damage to the coating may be remedied using a
Senotherm spray.
Guarantee
The guarantee does not cover damage due to insufcient maintenance!
