Gas Connection - Immergas VICTRIX OMNIA Instructions And Recommendations

1.7

GAS CONNECTION

Our boilers are designed to operate with methane gas (G20) LPG
and propane air (50% air - 50% propane). Power supply pipes must
be the same as or larger than the 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 nameplate).
If different, the boiler must be converted for operation
with the other type of gas (see converting appliance for
other gas types).
It is also important to check the dynamic
pressure of the mains (methane or LPG)
used to supply the boiler, which must
comply with EN 437 and its attachment,
as insufficient levels may reduce genera-
tor output and cause discomfort to the
user.
Static/dynamic network pressures high-
er than those required for regular opera-
tion may cause serious damage to the ap-
pliance control elements; in this case
shut the gas line off.
Do not operate the device.
Have the device checked by experienced
personnel.
According to the local regulation in force, make sure
that a gas cock is installed upstream of each connection
between the appliance and the gas system. This cock, if
supplied by the appliance's manufacturer, can be direct-
ly connected to the appliance (i.e. downstream from the
pipes connecting the system to the appliance), according
to the manufacturer's instructions.
The Immergas connection unit, supplied as an optional
kit, also includes the gas cock, whose installation in-
structions are provided in the kit.
In any case, make sure the gas cock is connected proper-
ly.

The gas supply pipe must be suitably dimensioned according to
current regulations in order to guarantee correct gas flow rate to
the burner even in conditions of maximum generator output and
to guarantee appliance efficiency (technical specifications).
The coupling system must conform to standards in force (EN
1775).
The appliance is designed to operate with fuel gas free
from 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 (nitro-
gen) that degrade the mixture delivered to the appliance casing
functioning anomalies.
- Due to the composition of the LPG mixture, layering of the mix-
ture components may occur during the period of storage in the
tanks. This can cause a variation in the calorific value of the
mixture delivered to the appliance, with subsequent change in
its performance.
