Storage tanks (in case of supply from LPG depot).
- New LPG storage tanks may contain residual inert gases (nitro-
gen) 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 calorific value of the
mixture delivered to the appliance, with subsequent change in
its performance.
1.10 HYDRAULIC CONNECTION.
In order not to void the product warranty, before
making unit connections, carefully clean the heating
system (pipes, radiators, etc.) with special pickling or
de-scaling products to remove any deposits that could
jeopardise proper unit operation.
A treatment of the heating and water 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. scale),
slurry or other hazardous deposits.
Indoor Unit hydraulic connection.
Water connections must be made in a rational way using the cou-
plings on the indoor unit template. The safety valve outlet of the
indoor unit must be connected to a draining funnel. Otherwise,
the manufacturer of the indoor unit declines any responsibility
in case of flooding if the drain valve cuts in.
ATTENTION:
the manufacturer declines all liability
in the event of damage caused by the
installation of an automatic filling system.
In order to meet the system requirements established by EN 1717
in terms of pollution of drinking water, we recommend installing
the anti-backflow kit to be used upstream of the cold water inlet
connection of the boiler. We also recommend using a category 2
3 heat transfer fluid (ex: water + glycol) in the boiler’s primary
circuit (CH circuit), as defined in standard EN 1717.
To preserve the duration of the indoor unit 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.
3 bar safety valve
.
Discharge of the safety valve has been conveyed to the condensate
drain trap outlet. Consequently, in the event of valve intervention,
the discharged liquid will end up in the sewer system through the
drain pipe of the condensate drain trap.
In any case the lower part of the appliance is fitted with a drain
fitting (Ref. 3 Fig. 10) with the relative closure cap to check for
the presence of liquid in the discharge circuit and to check the
intervention of the 3 bar safety valve.
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 occlusion and freezing of the liquid
contained in it. Before appliance ignition, ensure that the con-
densate can be correctly removed. After first ignition, check that
the drain trap is filled with condensate (Para. 1.31). Also, comply
with national and local regulations on discharging waste waters.
In the event condensate is not discharged into the wastewater
drainage system, a condensate neutraliser must be installed to
ensure compliance with the parameters established by the legis-
lation in force.
ATTENTION:
If you are using one or more booster
pumps it is essential to install a hydrau-
lic separator (not supplied by Immergas)
downstream of the indoor unit.
