4.3. Regularly check the conditions of gas hose, and gas regulator if it must be replaced
only use original spare parts.
4.4. Before starting any maintenance operation on the heater disconnect from both gas
and electrical suppliers.
4.5. 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:
4.5.1. Periodically check the gas supply hose conditions and, should it be changed, use
only original spare parts.
4.5.2. Check the starting electrode position (see Fig.4).
4.5.3. 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.
