1.4 CONNECTION UNIT (SUPPLIED AS
STANDARD WITH THE BOILER).
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 gas free of impurities;
otherwise it is advisable to fit special filters
upstream from the appliance to restore the
purity of the gas.
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.
Hydraulic connection.
Attention:
In order not to void the warranty
before making the boiler connections, carefully
clean the heating system (pipes, radiators, etc.)
with special pickling or de-scaling products to
remove any deposits that could compromise
correct boiler operation.
A chemical treatment for the thermal system
water is prescribed according to the current
technical regulations, until the system and the
lime scale apparatus is preserved (for example,
limescale deposits), from the slurry formation
and other noxious 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.
Important:
to preserve the duration of appliance
efficiency features, 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 having an
internal diameter 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.
Electrical connection:
The “Victrix Superior
TOP 32 X E” boiler has an IPX5D protection
rating for the entire appliance. Electrical safety of
the appliance is reached only when it is correctly
connected to an efficient earthing system as
specified by current safety standards.
Attention: Immergas S.p.A. declines any
responsibility for damage or physical injury
caused by failure to connect the boiler to an
efficient earth system or failure to comply with
the reference standards.
Also ensure that the electrical installation
corresponds to maximum absorbed power
specifications as shown on the boiler data-plate.
Boilers are supplied complete with an “X” type
power cable without plug. The power supply
cable must be connected to a 230V ±10% / 50Hz
mains supply respecting L-N polarity and earth
connection . This network must also have
an omnipolar circuit breaker with class III over-
voltage category.
To protect against possible voltage dispersions,
it is necessary to envision a differential safety
device type A.
When replacing the power supply cable, contact
a qualified technician (e.g. the Immergas After-
Sales Technical Assistance Service). The power
cable must be laid as shown (Fig. 1-3).
In the event of mains fuse replacement on the
P.C.B., use a 3.15A quick-blow fuse. For the
main power supply to the appliance, never use
adapters, multiple sockets or extension leads.
