Installation
Connections
Gas connection
The heating appliance is designed to
belong to the following categories for
the use of gas types.
Ensure by means of the name plates
to be found on the packaging and the
appliance that the heating appliance is
intended for the country in which it is
to be installed and that the gas
category corresponds to one of the
appropriate categories in the intended
country.
The gas inlet must be manufactured
and measured according to the
relevant specific regulations as well as
the maximum output of the equipment;
check also the correct calculation and
conection of the stop valve.
Before installation, the gas line should
be thoroughly cleaned, so that any
residues do not impair the functional
efficiency of the heating appliance.
Over and above this, it should be
further guaranteed that the type of gas
used is suitable for the heating
appliance (see name plate in the
interior of the appliance). Check the
required gas pressure (natural gas or
liquid gas).
Water connection
All connections for water and gas are
evident from the illustration (page 8).
Ensure that the highest pressure of the
water conduit network does not
exceed 6 bar; with highest pressure
values a pressure reducing valve must
be installed.
The minimum pressure needed by the
appropriate devices for processing of
hot service water is about 0,2 bar.
On sizing the pipes and the heating
element of the appliance, the value of
the remaining conveyor height level
must be considered depending on the
required flow in accordance with the
values represented in the curve
picture (page 12) of the circulation
pump.
With combi appliance (type HSG) flow
limiters are built into the water switch.
This provides for a constant flow of
service water
(EURON 24 HSG = 8 Litre/Minute
EURON 30 HSG (only for Belgium)
= 10 Litre/Minute).
Underfloor heating
For underfloor heating, attach a
suitable safety thermostat to the
supply.
-
Remove the bridge from the clamps
(X3-01), which are situated on the
left of the instrument panel housing,
and attach the safety thermostats
for the floor heating to it.
Too high a flow temperature leads to
an operating lockout of the heating
appliance both in the service water
and in the heating operation; the error
code "110" appears on the display.
Operation is resumed by pressing the
RESET "6" key (page 28), after the
flow temperature has dropped.
