• The heater can also be used as a ventilator.
• In this case remove the gas supply hose and connect the plug of the heater to a suitable electrical supply.
• Set the fan switch to position I.

• The repairs or maintenance operations must only be carried out by qualified personnel.
• The unit must be checked by a qualified technician at least once a year.
• Regularly check the conditions of gas hose, and gas regulator if it must be replaced only use original spare parts.
• Before starting any maintenance operation on the heater disconnect from both gas and electrical supplies.
• If the unit has not been used for a long period we advise that a technician carries out a general check up before using. It is
important to control the following:
• Periodically check the gas supply hose conditions and, should it be changed, use only original spare parts.
• Check the starting electrode position (see Fig. 6).
• Check the connections of the safety thermostat and of the thermocouple: they must always be clean.
• If necessary clean the fan blade and the inside of the heater using compressed air.
