Cleaning
Any maintenance of the stove should only be carried out when it is cold. Daily maintenance is limited to
vacuum cleaning the stove externally, using the soft brush attachment. You can also dust the stove using a
dry, soft cloth or brush. But remember, only when the stove is cold. Do not use water, spirit or any other
kind of cleaner, as this will damage the lacquer.
Once a year, the stove should be thoroughly serviced. The combustion chamber should be cleared of ashes
and soot. The hinges and the closing hook must be greased with liquid copper fat spray (heat-resistant up
to 1100°C), see drawing I. Lift the door approx. ½ cm and spray copper fat onto the hinge leaf.
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 bottom and/or shaking grate.
• Use copper grease for hinges and locking hooks (see drawing I).
All service checks must be performed by an authorised fitter. Use only original spare parts.
Inside cleaning
The regulating rod must be moved to bottom position before sweeping to prevent soot and ashes from
entering the automatic air regulation system.
The smoke shelf and baffle plate is to be removed from the stove before cleaning (drawing F):
• Lift the smoke shelf (1) off the steel rail (2) at the back of the combustion chamber. Then lower it
beneath the holder (3) and tilt it out.
• The baffle plate (4) is lifted from the holders (5), under the top plate and edged out.
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 fire has
gone out!
Insulation
The efficient, but porous insulation of the combustion chamber may, in time, become worn and damaged.
Cracks in the insulation have no effect on the efficiency 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 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 10
0
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).
