MAINTENANCE
Warning
The following operations must be carried out by quali-
fied personnel only.
Before carrying out any maintenance operation the
heater must be disconnected from the mains. Therefore:
• Stop the machine as instructed above
• Turn off the disconnecting switch on the electric
switchboard.
• Wait until the heater has cooled.
CLEANING THE HEAT EXCHANGER AND THE COMBUSTION CHAMBER
For the heater to operate efficiently the heat exchanger and com-
bustion chamber must be cleaned after a period of prolonged use and
more frequently if too much soot builds up. Soot builds up when there
is not enough chimney draft, when the fuel is of very poor quality,
when the burner is regulated incorrrectly or when the heater is
switched on and off too frequently. If the heater starts vibrating when it
is turned on there is probably too much soot.
To get at the heat exchanger (1) take off the front panel (3) and
then remove the smoke box panel (2) and remove baffle plates (7). To
get at the combustion chamber (4) remove the burner (5).
CLEANING THE FAN
Remove any dirt or extraneous material from the mesh of the aspi-
ration grill (6) and if necessary clean the propeller with an air-suction
tool.
