than100m³.
1.8 Do not obstruct the inlet or outlet sections of the heater.
1.9 If the heater has to work for a long period at its maximum capacity, it’s possible that ice
will form on the cylinder. This is due to excessive vapour withdrawal. Not for this reason, or for
any other, should the cylinder be heated. To avoid this effect, or at least to reduce it, use a

FUEL GAS ODOR
LP gas and natural gas have manmade odorants added specically for detection of fuel gas leaks.
If a gas leak occurs you should be able to smell the fuel gas. Since Propane (LP) is heavier than
air you should smell for the gas odor low to the oor. ANY GAS OROR IS YOUR SIGNAL TO GO INTO
IMMEDIATE ACTION!
1. Do not take any action that could ignite the fuel gas. Do not operate any electrical switches.
Do not pull any power supply or extension cords. Do not light matches or any other source of
ame.Donotuseyourtelephone.
2. Get everyone out of the building and away from the area immediately.
3. Closeallpropane(LP)gastankorcylinderfuelsupplyvalves,orthemainfuelsupplyvalve

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.Checkthestartingelectrodeposition(seeFig.5).
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.
