1.5 GAS CONNECTION.
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
name 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 technical standards in force, as insufficient
levels can reduce generator output and cause
malfunctions.
Ensure correct gas cock connection. The gas sup-
ply pipe must be suitably dimensioned according
to current regulations in order to guarantee cor-
rect 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 technical
standards in force.
Fuel gas quality.
The appliance was designed
to operate with combustible gas free of impuri-
ties; 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 condensa-
tion 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 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),
slurry or other hazardous deposits.
Water connections must be made in a rational
way. 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.
Attention:
Immergas declines all liability in the
event of damage caused by the inclusion of auto-
matic filling that is not its own brand.
In order to meet the system requirements es-
tablished by the technical regulation in force in
relation to the 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 ef-
ficiency features of the appliance, in the presence
of water whose features can lead to the deposit of
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 appli-
ance to the drainage system must be carried out
in such a way as to prevent freezing of the liquid
contained in it. Before appliance ignition, ensure
that the condensate can be correctly removed.
After first ignition, check that the drain trap is
filled with condensate (para. 1.20). Also, comply
with national and local regulations on discharg-
ing 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 pro-
duction of condensate can be expelled properly.
