Commissioning
Preparation for operation
General
To ensure the safety and correct
Operation of the heating appliance
commissioning is to be carried out by
the authorized specialist, who fulfils
legal requirements.
Monitoring
Disconnect sealing plug to
condensate connection.
First commissioning
Fill hydraulic circuits
Proceed as follows:
-
Open the bleed valve of the
heating appliance and the valve
above the stainless steel heat
exchanger.
-
Loosen the closure of the
automatic bleed valve on the
circulation pump.
-
Slowly open the filler valve of the
heating appliance and shut the
bleed valve on the stainless steel
heat exchanger and on the
heating appliances, as soon as
the water enters. Shut the filler
valve, if the pressure shown on
the water pressure gauge reaches
1 bar.
Ensure that:
-
the closure of the automatic bleed
valve on the circulation pump is
loosened.
-
the information relating to the
appliance pressureon the
manometer is higher than 1 bar.
-
the gas valve is completely shut off.
-
the electrical connection has been
correctly undertaken.
Ensure in every case, that the
green/yellow earth wire is attached to
an earthing system.
To bleed the appliance, procced as
follows:
-
Set adjusting knob "10" on the front
switch panel to position "I" (on).
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 elctronics 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.
-
Bleed the heating appliance.
-
Open the service water, until the
circuit is completely aerated.
-
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
(installation Type B).
Fill the heating appliance
condensation discharge glass in the
siphon 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 into the atmosphere.
Open the gas tap and check the
tightness of all connections, including
on the heating appliance. Ensure at
the same time that no gas
consumption is indicated on the gas
meter. Fix any leaks. Unlock the
heating appliance 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:
-
Check that the type of gas used
corresponds to the type of gas
indicated on the nameplate of the
heating appliance.
-
Open doors and windows.
-
Avoid sparks and naked flames.
Power supply
-
Check that the voltage and
frequency of the power supply
conform to the data on the name
plate of the heating appliance.
-
Check whether on connecting to
the polarity L-N was observed.
-
Check that the earth is
connected.
