Morso 3440 Instructions For Installation And Use Manual page 18

a) Open doors and windows to ventilate room.
b) Let the fire out or eject and safely dispose of fuel from the appliance.
c) Check for flue or chimney blockage, and clean if required.
Do not attempt to relight the fire until the cause of the fume emission has been identified and
corrected. If necessary seek expert advice.
Extractor fan
There must not be an extractor fan fitted in the same room as the stove as this can cause the
stove to emit smoke and fumes into the room.
Permanent air vent
The stove requires a permanent and adequate air supply in order for it to operate safely and
efficiently.
In accordance with current Building Regulations the installer may have fitted a permanent air
supply vent into the room in which the stove is installed to provide combustion air. This air
vent should not under any circumstances be shut off or sealed.
Chimney cleaning
The chimney should be swept at least twice a year. It is important that the flue connection
and chimney are swept prior to lighting up after a prolonged shutdown period.
If the stove is fitted in place of an open fire then the chimney will require sweeping after a
month of continuous operation. This is a precaution to ensure that any "softer" deposits left
from the open fire usage have not been loosened by the higher flue temperatures generated
by the closed stove.
Periods of Prolonged Non-Use
If the stove is to be left unused for a prolonged period of time then it should be given
a thorough clean to remove ash and unburned fuel residues. To enable a good flow of air
through the appliance to reduce condensation and subsequent damage, leave the air controls
fully open.
Use of fireguard
When using the stove in situations where children, aged and/or infirm persons are present a
fireguard must be used to prevent accidental contact with the stove. The fireguard should be
manufactured in accordance with BS 8423:2002 (Replaces BS 6539).
Use of operating tools
Always use the operating tools provided when handling parts likely to be hot when the stove
is in use.
Aerosol sprays
Do not use an aerosol spray on or near the stove when it is alight.
