1.5 GAS CONNECTION
(APPLIANCE CATEGORY II
2H3B/P
).
Our boilers are designed to operate with methane
gas (G20) and LPG. Supply pipes must be the
same as or larger than the 1/2”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 be in compliance, as
insufficient levels can reduce generator output
and cause malfunctions.
Ensure correct gas cock connection. 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.
1.6 HYDRAULIC CONNECTION.
Attention: in order not to void the condensation
module warranty, before making the boiler
connections, carefully wash the heating system
(pipes, radiators, etc.) with special pickling or
descaling products to remove any deposits that
could compromise correct boiler operation.
A chemical treatment of the thermal system
water 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), slurry or other hazardous deposits.
Water connections must be made in a rational
way using the couplings on the boiler template.
The boiler safety valve outlet must be connected
to a draining funnel. Otherwise, the manufacturer
declines any responsibility in case of flooding if
the drain valve cuts in.
In order to meet the system requirements
established by the regulations in terms of
pollution of drinking water, we recommend
installing the IMMERGAS anti-backflow kit to be
used upstream of the cold water inlet connection
of the boiler. It is also recommended that the heat
transfer fluid (e.g. water + glycol) entered in the
primary circuit of the boiler (heating circuit),
complies with the local regulations in force.
Attention: to preserve the duration and the
efficiency features of the appliance, in the presence
of water whose features can lead to the deposit
of lime scale, installation of the “polyphosphate
dispenser” kit is recommended.
Condensate drain.
To drain the condensate
produced by the appliance, it is necessary to
connect to the drainage system by means of
acid condensate resistant pipes, with an internal
Ø of at least 13 mm. The system connecting the
appliance to the drainage system must be carried
out in such a way as to prevent freezing of the
liquid contained in it. Before appliance start-up,
ensure that the condensate can be correctly
removed. Also, comply with national and local
regulations on discharging waste waters.
Condensate collection tray drainage.
The boiler
in the lower part is equipped with a fitting for
draining condensate which may possibly form
due to the circulation of chilled water. Before
appliance start-up, ensure that an excessive
production of condensate can be expelled
properly.
