Installation
Danger!
Risk of scalding and/or damage due to
incorrect installation leading to escaping
water.
Stresses in the supply line can cause leaks.
▶
Make sure there is no voltage in the sup-
ply lines when they are installed.
Caution.
Risk of material damage caused by
residues in the pipelines.
Welding remnants, sealing residues, dirt or
other residues in the pipelines may damage
the product.
▶
Flush the heating installation thoroughly
before installing the product.
5.1
Checking the gas meter
▶
Make sure that the existing gas meter is capable of
passing the rate of gas supply required.
5.2
Gas and water connections
Caution.
Risk of damage caused by incorrect gas
connection installation.
Excess test pressure or operating pressure
may cause damage to the gas valve.
▶
Check the leak-tightness of the gas valve
using a maximum pressure of 11 kPa
(110 mbar).
Caution.
Risk of material damage caused by corro-
sion
Due to non-diffusion-tight plastic pipes in the
heating installation, air gets into the heating
water. Air in the heating water causes corro-
sion in the heat generator circuit and in the
product.
▶
If you use non-diffusion-tight plastic pipes
in the heating installation, ensure that no
air gets into the heat generator circuit.
Caution.
Risk of material damage due to heat trans-
fer during soldering.
▶
Only solder connection pieces if the con-
nection pieces are not yet screwed to the
service valves.
Note
Apply thermal insulation to the water pipes to the
boiler outlet and to the system.
Preliminary work
1.
Check that the system volume and the volumetric capa-
city of the expansion vessel are compatible.
▽
If the volume of the expansion vessel is insufficient
for the system.
▶
Install an additional expansion vessel in the
heating return, as close to the product as pos-
sible.
▶
Install a non-return flap at the product's outlet
(heating flow).
2.
Ensure that the system has the following components:
–
A cold water stop cock for the unit
–
A gas stopcock for the unit
–
A filling and draining device in the heating installa-

1.
Connect the water and gas connections in accordance
with the applicable standards.
2.
Purge the gas line before start-up.
3.
Check whether the connections (
