1.7 GAS CONNECTION.
Our boilers are designed to operate with with
natural gas (G20) and L.P.G. Supply pipes must be
the same as or larger than the 3/4” G boiler fitting
Victrix Pro 80 2ErP, 1“ Victrix Pro 100-120 2ErP.
N.B.:
the gas supply pipe must be suitably di-
mensioned 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 connection to the gas supply
must conform to standards.
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 convert-
ing appliance for other gas types). The dynamic
gas supply (methane or L.P.G.) pressure must
also be checked according to the type used in
the boiler, which must comply with EN 437 and
relative attachments and with the local technical
regulations in force, as insufficient levels can
reduce generator output and cause malfunctions.
Ensure correct gas cock connection.
Install a manual cut-off valve with quick closure
manoeuvre for 90° rotation and end run stops in
the all open or all closed positions on the gas sup-
ply pipe in a visible and easily reachable position
outside the room where the appliance is installed.
N.B.:
the internal gas supply system must be
built in compliance with the provisions and
regulations and all legislation in force, and any
other reference on good technique.
Fuel gas quality.
The appliance has been de-
signed 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 causing problems
with boiler operation.
- 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.
1.8 HYDRAULIC CONNECTION.
Attention:
in order not to void the condensation
module warranty, before making the boiler con-
nections, carefully wash the CH system (pipes,
radiators, etc.) with special pickling or descaling
products to remove any deposits that could com-
promise correct boiler operation.
A chemical treatment of the thermal system wa-
ter is required, in compliance with the technical
standards in force, in order to protect the system
and the appliance from deposits (e.g., lime scale),
sludge or other hazardous deposits.
It is recommended to prepare a filter in the
system to collect and separate any impurities
present in the system (slurry remover filter). In
order to avoid deposits, scaling and corrosion
in the central heating system, the provisions
set forth in the technical regulation in force on
water treatment in heating systems for civil use
must be respected.
Water connections must be made in a rational
way using the couplings on the boiler template.
The discharge of the boiler safety valve must
be connected to a tundish and then the waste
should be connected to the sewer. Otherwise, the
manufacturer declines any responsibility in case
of flooding if the drain valve cuts in.
