Routine Stove Maintenance; External Maintenance; Internal Maintenance - Morso 8710 Instructions For Installation And Use Manual

The stove door should normally be opened gently the first 2 - 3 centimetres, then you
should wait until the pressure has equalised before opening the door all the way. This tech-
nique will prevent smoke from getting out, particularly when there is a poor draught.
The stove door should never be opened when the stove is being fired vigorously.
Once the wood has burned out, it becomes glowing charcoal. If a good layer of embers has
already formed on top of a sufficient layer of ash, the stove can keep warm for a very long
time, not least due to the favourable qualities of the cast iron.
We would strongly recommend that you do not leave your stove alit at night.
It harms the environment, and constitutes very poor use of the wood, as the
gases in the wood do not ignite at the low temperature, but settle as soot
(unburned gases) in the chimney and stove. Extreme conditions, such as poor
draught in the chimney, large quantities of wood or wet wood, may, in the
worst-case scenario, cause an explosive ignition.
When firing in the summer period, when there is minimal need for heat, the
combustion will be poor. The stove provides too much heat, so the combustion
should be reduced. But always remember to make sure that there are lasting
flames until the wood becomes charcoal. If you want a weaker fire, stoke up
using less wood.
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, 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 nor-
mal 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 a cleaning agent
such as 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.
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 ordi-
nary 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 natu-
rally 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.
