HWAM 4660 - Maintenance and Servicing; Daily and Annual Cleaning; Service Inspection Schedule

22
It is recommended that you use birch or beech wood that has been chopped and stored for at least
one year in an open shed exposed to sun and wind. The wood must be dry (max. 18% water contents)
before it is stored indoors. It is recommended that kindling wood is stored indoors for a couple of
days prior to use.
Briquettes give off a lot of heat. Certain types expand considerably, thus causing an uncontrollable com

bustion.
The stove is EN 13240 approved for ring wood only. No particle board, lacquered, painted
or treated wood, plastics, or rubber may be burned.

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
degrees Celsius), see drawing G. 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 are no longer soft.
• Checking and/or replacing insulation material.
• Checking the construction (only some countries).
• Checking the combustion chamber base.
• Use copper grease for hinges and locking hooks (see drawing G).
All service checks must be performed by an authorised tter. Use only original spare parts
Inside cleaning
Remove the top smoke shelf and the two-part steel smoke guide plate from the stove before cleaning
(Drawing E).
• 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 efcient, but porous insulation of the combustion chamber may, in time, become worn and damaged.
Cracks in the insulation have no effect on the efciency 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.
