Immergas VICTRIX HYBRID PLUS Manual page 21

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. This 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.
The 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.
The gas supply pipe must be suitably dimensioned according to current regulations in order to guarantee correct gas flow rate to the burn-
er 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 (nitrogen) that degrade the mixture delivered to the appliance casing func-
tioning 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 calorific value of the mixture delivered to the appliance, with subsequent change in its performance.
