7.1 Preliminaries
The whole of the system, with the pump removed, should be
thoroughly flushed out with cold water.
Refit the pump and fill the system.
Examine for water soundness and vent all air from the system,
including the pump. Make sure that all valves are open.
7.2 Initial Lighting, Testing and Adjustment
Caution. The following should be carried out by a competent
person.
Identify the controls by reference to diagram 7.1.
Check that the gas service cock “K” is closed, indicator slot
vertical.
Make sure that the thermostat phial is fully inserted in the phial
pocket “J” and is securely located by the retaining split pin.
Check that the mains electrical supply is switched off.
Set thermostat control knob “B” to “O”.
Remove the burner pressure test point screw “G” and fit a
suitable pressure gauge.
Open gas service cock “K”, slot horizontal.
Note: Make sure the Flue Blockage Safety Device reset button
'P' is fully pushed in.
Turn gas control knob “A” to ' ' pilot ignition position and push
in. At the same time push and release button “C” until the pilot
burner lights, view through window “E”. At this stage air may be
present in the supply pipes so this operation may need to be
repeated.
When the pilot burner lights, keep knob “A” fully pushed in for
about 15 seconds. If the pilot burner fails to stay alight repeat
the operation only this time keep knob “A” pushed in for a little
longer.
Note: Should the boiler fail to operate correctly refer to the Fault
Finding - Section 10.
If gas control knob “A” is turned to ' ', a safety lock prevents
it being turned on again. No attempt should be made to push
in and turn knob “A” until three minutes have gone by.
Make sure that the pilot burner is alight and stable, see diagram
7.2, for flame dimensions, switch on the electrical supply. Set
any remote controls so that they are calling for heat. Turn
control knob “”A” to '
' main burner position. Set thermostat
control knob “B” between “MIN” and “MAX”, the main burner will
light. “MAX” is about 82
o C (180 o F).
Test for gas soundness around the boiler gas components with
a suitable leak detection fluid.
Ten minutes after lighting, check the burner setting pressure
and adjust if necessary, as follows, remove cover “F”, see
diagram 7.1 and turn adjustment screw to obtain the required
heat input, turn anticlockwise to decrease, see diagram 7.1 data
label “L” for settings. Replace cover.
If any doubt exists the gas rate should be checked at the gas
