MAINTENANCE
For proper working efficiency the fans, the combustion chamber
and the burner must be cleaned periodically.
Warning
Before performing any maintenance operations:
• Stop the machine as indicated in the "STOP" para-
graph;
• Disengage the power supply by removing the plug from
the power socket;
• Close the gas supply stopcock;
• Wait until the heater has cooled down.
Cleaning must be carried out by removing any foreign bodies from
the fan suction grills.
Warning
Do not direct jets of compressed air towards the air pres-
sure intakes near the main fan: the air pressure switch
could be permanently damaged.
