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.
For proper maintenance of the soapstone cladding, see the separate instructions that accompanied the
soapstone set.
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 H. 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.
• Check the spring in the HWAM
®
Autopilot™ unit and replace if necessary.
• Checking gaskets. Replace gaskets if they are not intact or have softened.
• Checking of heat insulating material and possibly replacement.
• Checking of the bottom/shaking grate.
• Lubricating the hinges and the locking hook with cobber grease (drawing K).
All service checks must be performed by an authorised fitter. Use only original spare parts.
Inside cleaning
Before chimney sweeping can be performed, the air control knob must be set to its minimum position to
prevent soot and ash from entering the HWAM
®
Autopilot™. Unless the safety fittings for transportation
have not already been removed, twist the safety fittings for transportation off the two hooks by using pliers or
a screwdriver. The smoke shelf and baffle plate is to be removed from the stove before cleaning (drawing F).
• First lift the smoke shelf (1) out of the steel rail (2) at the back of the combustion chamber. Next, lower
it beneath the holders (3) and slide it out.
• Lift each half of the steel smoke plate (4) off the holder (5) behind the smoke pipe, and remove them
from the hook (6) beneath the top plate.
Ashes
The ash pan is best emptied by pulling a waste bag over the pan, tipping it and then carefully pulling it out
of 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, 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.
HWAM

Autopilot™ (Drawing G)
If the stove has top outlet, lift off the convection grate (1), remove the rear part of the top plate (2)
and replace the convection grate so that it rests on the flue duct and the front part of the top plate. Lift
off the slabs (4) on the rear left-hand side of the stove by first lifting the slabs and then removing them.
