CLEANING THE HEAT EXCHANGER AND THE COM-
BUSTION CHAMBER
For the heater to operate effi ciently the heat exchanger and
combustion chamber must be cleaned after a period of prolon-
ged 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 incorrectly
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 internal parts of the heat exchanger (1), remove
the burner (2), take off the upper back panel (3), the exchanger
inspection panels (4) and the baffl e plates (5). Clean out soot or
extraneous material with a vacuum cleaner or tube cleaner.
CLEANING THE FAN
Remove any dirt or extraneous material from the mesh of the
aspiration grill (6) and if necessary clean the propeller with an
air-suction tool.

gularly by an Authorized Service Technician. All cleaning, servi-
cing and regulation operations must be carried out as indicated
in the Burner Instruction Manual.
