11.5 Initial Lighting
The lighting procedure of the boiler is fully automated.
Check that all external controls are calling for heat.
The appliance will enter a self checking routine then the fan
should start and the ignition will commence.
If the burner fails to light the boiler will block. Initially this may
be due to air in the gas supply line. The boiler will automatically
have some attempts at ignition.
If the burner fails to ignite the indicator will turn on.
Turn the left knob on position and then turn it on previous
operating position to repeat the ignition sequence.
Once the system has been purged of air set the hot water to
the desired temperature by using the Hot Water knob .
Open a hot water tap, the diverter valve will move to hot water
supply.
Check that hot water is available and then close the hot water
tap.
Set the Central heating water temperature to the desired tem-
perature by turning the Central Heating knob on the scale .
The appliance will then continue to fi re in central heating un-
til the user controls are satisfi ed or there is another demand
made for hot water.
11.6 Testing
Should any doubt exist about the gas rate, check it using the
gas meter test dial and stop watch at least 10 minutes after
the burner has lit, making sure that all other gas burning appli-
ances and pilot lights are off.
It should be noted that this appliance will modulate the heat in-
put according to demand. This may affect the gas rates meas-
ured if the appliance reaches its operating temperature during
the measurement.
The approximate gas rates:
Betacom 24: 2.7m³/h
Betacom 30: 3.1m³/h
The gas valve is factory set for natural gas (G20) and should
need no adjustment.
Re-setting of the gas valve requires a combustion analyser and
any adjustment should only be carried out by a competent per-
son.
11.7 Testing - Heating System
Check that all external controls are calling for heat. The boiler
will fi re automatically. Fully open all radiator valves, fl ow con-
trol valve, if fi tted, see diagram 4.1.
Balance the radiators as required and if fi tted adjust valve to
give the required system differential. Turn off all radiators that
can be shut off by the user and check to see if less than the
maximum differential allowed of 20°C can be achieved across
fl ow and return.
The pump’s speed can be adjusted depending on the require-
ments of the central heating system, see diagram 4.2.
The appliances have an inbuilt automatic bypass valve.
Allow the system to reach maximum temperature then switch
off the boiler by isolating from the electrical supply.
Drain the entire system rapidly whilst hot, using the drain tap
at the lowest part of the system. Fill and vent the system as
described previously in section 11.1.
Lock or remove the handle from control valve, if fi tted.
11.8 Completion
Adjust the boiler temperature control and any system controls
to their required settings. In addition it is necessary to complete
the “Benchmark” logbook.
For IE, it is necessary to complete a “Declaration of Conformity”
to indicate compliance to I.S.813. An example of this is given in
the current edition of I.S.813.
Testing Flue Gases: If any doubt exists that the fl ue products
are not exhausting correctly, investigate by use of a gas ana-
lyser (FGA).
