1.3 CONNECTIONS (OPTIONAL).
Gas connection (Appliance category II
2H3+
).
Our boilers are designed to operate with methane
gas (G20) or LPG. Supply pipes must be the same
as or larger than the 3/4”G boiler fitting. Before
connecting the gas line, carefully clean inside
all the fuel feed system pipes to remove any
residue that could impair boiler efficiency. Also
make sure the gas corresponds to that for which
the boiler is prepared (see boiler data-plate).
If different, the appliance must be converted
for operation with the other type of gas (see
converting appliance for other gas types). The
dynamic gas supply (methane or LPG) pressure
must also be checked according to the type
used in the boiler, which must comply with the
regulations in force, as insufficient levels can
reduce generator output and cause malfunctions.
Ensure correct gas cock connection by following
the mounting instructions illustrated in the
figure. The gas supply pipe must be suitably
dimensioned according to current regulations
in order to guarantee correct gas flow to the
burner even in conditions of maximum generator
output and to guarantee appliance efficiency
(technical specifications). The coupling system
must conform to standards.
Fuel gas quality.
The appliance has been
designed to operate with combustible gas free of
impurities; otherwise it is advisable to fit special
filters upstream of the appliance to restore the
purity of the fuel.
Storage tanks (in case of supply from LPG
depot).
- New LPG storage tanks may contain residual
inert gases (nitrogen) that degrade the mixture
delivered to the appliance casing functioning
anomalies.
- Due to the composition of the LPG mixture,
layering of the mixture components may occur
during the period of storage in the tanks. This
can cause a variation in the heating power of
the mixture delivered to the appliance, with
subsequent change in its performance.
