MAINTENANCE
WarningThe following operations must be carried out by
qualifi ed 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 swit-
chboard
• Wait until the heater has cooled.
CLEANING THE HEAT EXCHANGER AND THE COMBU-
STION 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 incorrrectly
or when the heater is switched on and off too frequently. If the
heater starts vibrating when it isturned 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 baffl e 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
aspiration grill (6) and if necessary clean the propeller with an
air-suction tool.
CLEANING THE BURNER
For the heater to work effi ciently the burner must be serviced
regularly by an Authorized Service Technician. All cleaning, servi-
cing and regulation operations must be carried out as indicated in
the Burner Instruction Manual.
TRANSPORTING AND MOVING
THE HEATER
Warning: Before moving a unit:
• Turn it off as indicated above
• Disconnect electricity by pulling out the plug
• Wait until the heater cools down
The heater has four hooking points at the four top corners. The
heater should be moved or lifted by means of ropes or chains
connected to the hooking points.
The heater can be:
• suspended with ropes and/or chains or aupporting beams
• mounted on a supporting base.
In both cases check carefully in the Technical Specifi cations that
all parts of the heater can take the strain of lifting.
Warning: Never try to lift the heater manually. Doing so could
result in physical injury.
