Caution:
Never empty ash when the heater is in operation.
Never use your household or shop vacuum cleaner to remove ash from the heater as it may still
contain hot coals.
Always dispose of ash in a metal container.
Creosote formation
Your Morsø heater is equipped to burn the wood cleanly and efficiently however, if the chimney draft
is poor or when wood is burned too low or too slowly, tar and other organic vapors can be produced
and when combined with expelled moisture from the fuel, hazardous creosote is formed. The hazard
is worsened when the creosote vapors condense inside cool chimney and the risk of a chimney fire is
dramatically increased.
A monthly inspection of the flue is highly recommended.
Chimney sweeping & inspection
No matter how often you use your Morsø heater you should establish a monthly inspection routine of
the heater and chimney system especially during the heating season.
Perform a chimney inspection when the heater is not in use. Using a mirror, look up through the
chimney connector collar and look for visible signs of creosote build-up.
If you unable to inspect the flue system through the heater, it must be disconnected from the chimney
connector to provide better viewing access.
Cleaning the chimney must be done using a brush the same size and shape as the flue liner or chimney
system. Run the brush up and down the liner several times until all soot deposits have fallen to the bot-
tom of the chimney where they can be removed through a clean-out door or from inside the heater (if
still connected) using a vacuum cleaner.
Some models may require baffle removal (see page 25)
The chimney connector should be cleaned in a similar way using a stiff wire brush. This procedure
might be better performed outside. Reinstall the connector sections after cleaning, making sure to
secure the joints between the individual sections with sheet metal screws.
If you cannot inspect or clean the chimney yourself, contact your local certified chimney
sweep or your approved Morsø Dealer.
if you do experience a chimney fire, you must act promptly
1.
Completely close the primary air control.
2.
ensure ALL persons have vacated the building.
3.
CALL THe Fire DepArTMeNT.
Annual maintenance
Prior to every heating season you should thoroughly clean and inspect the entire installation, repairing
any damage, and replace any parts that show signs of wear & tear.
Thoroughly clean and inspect the chimney and chimney connector.
Have a contractor make any necessary repairs to a masonry chimney.
Check door & ceramic glass gaskets for wear or compression and replace if necessary.
Check the glass for cracking; replace if needed.
Check door and handles for tightness and adjust if needed.
Leaving the heater for extended periods
important notice:
When the heater is to be left unused for a long period of time (summer months etc) it is essential to
clean it out thoroughly and leave the primary air control lever (or dial) open to allow airflow around the
combustion chamber and chimney. Ventilating your heater and chimney will prevent excessive corrosion
from moisture present in the chimney.
Make sure that the chimney has adequate protection from the rain and that rain water cannot come
into contact with the heater; install a chimney rain cap, but do not under any circumstances block off
the flue completely.
Warning: if moisture is allowed to settle within the heater, rust will form. As it takes a grip rust will
cause cast iron to swell. This can lead to undue pressure on the plate joints and in turn may result in
damage to the heater.
Words of wisdom
It is good practice to thoroughly clean the heater immediately after the heating season. Adding a desic-
cant, such as kitty litter into the heater bottom will help absorb excess moisture during the summer
months. However, be sure to remove this prior to the heating season.
