7.1 Commissioning and Testing the Boiler
The whole of the system should be thoroughly flushed out with
cold water with the pump removed. Make sure that all valves
are open. Refit the pump and fill the system. Examine for water
soundness and vent all air from the system, including the pump.
CAUTION: The following work should be carried out by a
competent person.
Identify the boiler controls by reference to diagram 7.1.
Check that the gas service tap “K” is closed, indicator line
horizontal.
Open all windows and put out any naked lights, pipes or
cigarettes.
Purge air from the gas supply in accordance with the current
issue of BS6891.
Make sure that the thermostat phial is positioned at the bottom
of the phial pocket “J” located by the washer being behind the
split pin.
See that the mains electrical supply is switched off.
Set thermostat control knob “B” to “O”.
Remove gas pressure test nipple screw “G” and fit a suitable
pressure gauge.
Turn gas control knob “A” to ignition and pilot position and
push in. At the same time push and release piezo unit button
“C” until the pilot burner lights. At this stage air may be present
in the gas pipes and the lighting operation may need repeating.
When the pilot is alight, keep control button “A” fully pushed in
for about 15 seconds. If the pilot burner fails to remain alight,
repeat the lighting procedure but now keep the control button
pushed in for a little longer.
If the gas control knob “A” is turned to , a safety lock
prevents it being turned on again. No attempt should be made
to push in knob “A” until 3 minutes have elapsed.
Make sure that the pilot burner is alight and stable, see diagram
7.2 for flame dimensions, then switch the electrical supply on.
Set any remote controls for duty. Turn control knob “A” to main
burner position ' '. Set thermostat control knob “B” between
“MIN” and “MAX” opposite the setting point on the control box,
the main burner will then light, “MAX” is about 82
o C (180 o F).
Test for gas soundness around the boiler with a suitable leak
detection fluid.
Set the burner gas rate required ten minutes from lighting, see
page 2 for settings. Adjust screw “F”, diagram 7.1 to obtain the
required heat input. Turn anti-clockwise to increase. The
adjusting screw should then be sealed.
Should there be any doubt about the gas rate it should be
checked at the meter.
This should be in the range of 1.8 to 2.0m 3 /h (63 to 71ft 3 /h).
These rates are for guide purposes, depending on the heat
setting.
Stick the self adhesive arrow indicator onto the data label
against the output the boiler is to be set to, the arrow is in the
fittings pack.
Check the operation of the flame failure device as follows: with
the main burner alight, turn gas control knob “A” fully anti-
clockwise to its stop ' ', the main and pilot burners will go out.
