Condense Connection
Commissioning
Preparation for operation
General
To ensure the safe and correct operation
of the boiler, commissioning must be
carried out by a suitably qualified
specialist.
Monitoring
Ensure condensate connection is
connected using the condense drain
hose supplied or using plastic piping.
Ensure that the Condense outlet is
piped to a suitable drain. Please refer to
BS6798 for ultimate guidance
First commissioning
Fill hydraulic circuits
Proceed as follows:
Open the boiler bleed valve and the
valve above the stainless steel heat
exchanger.
Loosen the closure of the automatic
bleed valve on the circulation pump.
Slowly open the system filling point
and shut the bleed valve on the
stainless steel heat exchanger, and
the boiler, as soon as water is
evident. Shut the filler valve, once
the pressure shown on the water
pressure gauge reaches 1.0 bar.
Ensure that:
The the automatic bleed valve on
the circulation pump is opened.
The boiler pressure, on the
manometer is 1 bar. The gas valve
is completely shut off. The electrical
connection has been correctly
made.
Ensure in every case, that the
green/yellow earth wire is connected to
a suitable earth.
To bleed the appliance, proceed as
follows:
Switch on boiler (10). This sets the
pump of the heating appliance in
operation and there are three
consecutive attempts to ignite the
burner. After the third attempt the
electronics lock the appliance, as
the gas supply is cut; the display
shows the readout "133".
Allow the pump to work until all the
air has left the appliance. Vent the
boiler. Check the appliance
pressure and refill with water in the
case of a drop in pressure, until
pressure again reaches 1 bar.
Check the flue gas system.
Ensure that any necessary room
ventilation openings are open.
Ensure the boiler condensation
siphon is filled with water.
(See illustration below centre).
If the appliance is unused for a long
period, the siphon must be filled
before switching on again. It is
dangerous not to refill the siphon with
water, as this can cause the flue gas
to escape from the condense drain.
Open the gas tap and check the
tightness of all connections. Unlock
the boiler by pressing the Reset key
"6". The burner will ignite. Should this
not happen, repeat the above
procedure, until the burner ignites.
Gas supply
Proceed as follows:
Ensure that the type of gas used
corresponds to the type of gas
indicated on the nameplate of the
boiler.
Power supply
Ensure that the voltage and frequency
of the power supply conform to the
data on the name plate of the boiler.
Ensure that the live and neutral
connections have been made and to
the correct terminals. Check that the
earth is connected.
