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. Use copper grease for hinges and locking hooks (see drawing H).
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 automatic 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.
• Use copper grease for hinges and locking hooks (see drawing H).
All service checks must be performed by an authorised fitter. 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 automatic control.
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, 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.
Automatics (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 30
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).
Door/glass
A sooty glass door can easily be cleaned with a piece of moist kitchen roll dipped in ash. Go about it
