Specifications

If you fire the stove using wet wood, a lot of the fuel’s thermal energy will be spent forcing the
water out of the wood, without releasing any heat to the stove. This incomplete combustion
results in a layer of soot being left in the stove, pipe and chimney.

3.0 Routine stove maintenance
3.1 External maintenance
The cast surface of the stove is painted with heat-resistant Senotherm paint. It is best maintained by
simply vacuuming it with a soft brush attachment or wiping it down with a dry, dustfree cloth.
If the stove is used too vigorously, the painted surface may assume a greyish tinge over time, but the
stove can easily be freshened up with Morsø spray paint, which is available from your local retailer.
Morsø stoves are painted using a Morsø Original Black (previously called Morsø dark grey) or Morsø
grey. The paint can be bought in a spray or a can.
3.2 Internal maintenance
Glass window
If the stove is used correctly, very little or no soot will be deposited on the ceramic glass window. If
soot does form on the glass as the stove is being lit, it will burn away once normal combustion begins
in the stove. If the glass window becomes thoroughly covered in soot due to incorrect operation, the
soot can be easily removed using Morsø Glass Cleaner. The glass must be cold when you clean it. Avoid
stoking the stove with pieces of wood that are so long that they press against the glass window when
the door is closed.
Only use Morsø Glass Cleaner.
Reasons for sooty glass window:
- The fuel is too wet
- The pieces of fuel are too big/uncut wood
- The combustion temperature is too low
- There is not enough air
Ceramic glass replacement
Ceramic glass cannot be recycled because it has a higher melting point that ordinary glass. If ceramic
glass is mixed with ordinary glass, the raw material is spoiled, and the reclaiming process may be halted.
Take care that the ovenproof glass does not end up among ordinary recycled waste. That will be a great
benefit to the environment. Note: Should be handed in to a recycling station as ceramic glass.
Internal cast-iron parts and/or wearing parts
The baffles and other components that come in direct contact with the fire and glowing fuel are all
wearing parts. As a result, they will be particularly susceptible to burn-through. When used correctly,
these parts will last for many years, but overly vigorous use will naturally accelerate the burn-through.
Such parts are all easily replaced.
If the baffles are damaged and are not replaced in time, the top plate will be exposed to such high
temperatures that it may be damaged as well.
Please note that no unauthorised alterations of the design may be undertaken, and that any parts
that are replaced must be replaced with original Morsø parts.
Reasons for overly rapid wear of internal parts
- Stove fired too vigorously
Use of very dry wood (wood from old furniture)
- Too much soot on top of the baffles (please see the section on Cleaning)
- Too much ash in the ash pan (please see the section on Ash)
Gaskets
The gaskets in the door will wear out over time, and should be replaced as required in order to prevent
runaway combustion. Use the original Morsø gasket kit.
NOTE: Normal wearing parts are not covered by Morsø’s extended warranty.
A selection of maintenance products (spare parts, glass cleaner, paint, gasket kit, etc.) is available from your
Morsø dealer.
3.3 Cleaning the stove
A layer of ash and soot will form as a result of the draught in the chimney and after sweeping, particularly
on the top of the smoke hood. This ash will have an insulating effect, which may speed up the burn-
through of the baffle.
During normal cleaning, the baffle can be removed from the stove. Once this part has been taken out,
you can access the flue chamber above the baffle and clean it. Clean the baffle before reassembling
them, and make sure that it is correctly assembled. Nowadays the chimney sweep must remove the
soot in the stove, in addition to sweeping the chimney and cleaning the flue pipe.
The number of annual sweepings/cleanings of the stove should be determined in consultation with your
chimney sweep.
Ash
As noted above, there should be a couple of centimetres of linsulating ash in the bottom of the
combustion chamber in order to achieve a high combustion temperature. If the layer of ash is too thick,
it can be brushed down into the ash pan.
Empty the ash pan before it gets completely full, so that the ash does not insulate around the grate, and
thereby speed up the burn-through.
