1.7 GAS CONNECTION

Our appliances are built to operate with methane gas (G20), LPG, propane air (50% air - 50% propane) and mixtures of methane and hy-

drogen up to 20% by volume (20%H2NG), referring to the gas distributed in the network. Power supply pipes must be the same as or

larger than the appliance tting.

Before connecting the gas line, carefully clean inside all the fuel feed system pipes to remove any residue that could impair ap-

pliance eciency.

Also make sure the gas corresponds to that for which the appliance is prepared (see appliance data nameplate).

If dierent, the boiler must be converted for operation with the other type of gas (see converting appliance for other gas types).

Data nameplate positioning

It is also important to check the dynamic pressure of the mains (methane or LPG) used to sup-

ply the boiler, which must comply with EN 437 and its attachment, as insucient levels may

reduce generator output and cause discomfort to the user.

Static/dynamic network pressures higher than those required for regular operation may cause

serious damage to the appliance control elements; in this case shut the gas line o.

Do not operate the device.

Have the device checked by experienced personnel.

According to the local regulation in force, make sure that a gas isolation valve is installed upstream of each connection be-

tween the appliance and the gas system. is valve, if supplied by the appliance’s manufacturer, can be directly connected to

the appliance (i.e. downstream from the pipes connecting the system to the appliance), according to the manufacturer’s in-

structions.

e Immergas connection unit, supplied as an optional kit, also includes the gas isolation valve, whose installation instruc-

tions are provided in the kit.

In any case, make sure the gas isolation valve is connected properly.
