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 F. 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 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.
• Use copper grease for hinges and locking hooks (see drawing F).
All service checks must be performed by an authorised fitter. Use only original spare parts.
Inside Cleaning
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. TThe smoke shelf and baffle plate is to be
removed from the stove before cleaning (Drawing E):
• 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.
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.
Seals
Check frequently to ensure that seals in the door and ash pan are intact and not brittle. Failing this, they
should be replaced. Use original seals only.
