Routine Stove Maintenance - Morso 4000 Instructions For Installation And Use Manual

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 main-
tained by simply vacuuming it with a soft brush attachment or wiping it down with a dry,
dust-free 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 to big/uncut wood.
- The combustion temperature is too low.
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 grate 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 ac-
celerate 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.
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).

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.
Gaskets
The gaskets in the doors 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 avail-
able 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 sweep-
ing, particularly on the top of the upper baffle. This ash will have an insulating effect, which
may speed up the burn-through of the baffles.
During normal cleaning, the baffles can be removed from the stove. Once the baffles have
been taken out, you can access the flue chamber above the baffles and clean it.
Clean the baffles before reassembling them, and make sure that they are correctly assem-
bled.
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 layer of approx. 1 cm insulating 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.
In most cases, the ash will need to be taken away by the waste disposal company. Because
embers may be concealed in the ash pan for several days, it may be necessary to store the
ash in a container made of non-flammable material before pouring it into a rubbish bag.
Ash from a wood-burning stove will not be of any benefit to your garden as fertiliser. If you
have burned colour brochures, or painted or treated wood, etc., in the stove, the resulting
ash must not be poured onto soil as it may contain heavy metals.
