Danger!
Risk of scalding and/or damage due to
incorrect installation leading to escaping
water.
Mechanical stresses in the connection pipes
may lead to leaks.
▶ Ensure that there is no mechanical stress
when installing the connection pipes.
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 corrosion 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 connectors if the connectors
are not yet screwed to the service valves.
Note
Apply heat insulation to the water pipes to the
boiler outlet and to the installation.
Preliminary work
1. Check that the system volume and the volumetric capacity of the expansion vessel are compatible.
▽ If the volume of the expansion vessel is insufficient
for the installation.
▶ Install an additional expansion vessel in the
heating return, as close to the product as possible.
▶ Install a non-return valve at the product's outlet
(heating flow).

5.3 Connecting the drain pipework for the
expansion relief valve
1
▶ Ensure that the pipeline is visible.
▶ The pipe must have a continuous fall and be routed to a
position so that any discharge of water, possibly boiling,
or steam cannot create any danger to persons, damage
to property or external electrical components and wiring.
◁ The piping must be installed in such a way that you
can see when water drips out.
5.4 Connecting the condensate discharge pipe
1
2
▶ Follow the instructions listed here and observe the legal
and local regulations on condensate discharge.
▶ Use PVC or any other material that is suitable for drain-
ing the non-neutralised condensate.
▶ If you cannot guarantee that the materials from which the
drain pipework is made are suitable, install a system for
neutralising the condensate.
Note
The condensate drain pipework must have a
continuous fall (45 mm per metre) and should
whenever possible terminate at a suitable
drain point within the heated envelope of the
building that will remain frost free under long
periods of low external temperatures.
▶ Connect the condensate traps (1). Use the supplied drain
hose (2) for this.
▶ Connect a condensate discharge pipe (21.5 mm, not
included in the scope of delivery) to the drain hose (2).
▶ During installation remove all burrs from inside of cut pipe
work and avoid excessive adhesive which may trap small
pockets of water close to the pipe wall which can freeze
and build into a larger ice plug.
▶ For any installation the condensate must be free flowing
and not be possible for air back-pressure to prevent water flow.
▶ As with other pipe work insulate the condensate dis-
charge pipe to minimise any risk of freezing and beware
when crossing cavities that the fall is maintained and the
pipe sleeved.
You can find further information in specification "BS 6798"
for installing and maintaining gas-fired boilers with a nominal
heat input below 70 kW.
