7.1 Preliminaries
With the pump removed the whole of the system 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 and pump. Make sure that all
valves are open.
7.2 Initial Lighting, Testing and Adjustment
CAUTION. The following procedure should be carried out by a
competent person.
Identify the boiler 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 connect
a suitable pressure gauge.
Open gas service cock “K”, indicator, horizontal.
Turn gas control knob “A” to' ' pilot/ignition position and
depress.
At the same time push and release piezo ignition button “C” until
the pilot burner lights, view through window “E”. At this stage air
may be present in that gas pipes, so this operation may need to
be repeated several times. When the pilot burner lights, keep
control knob “A” fully pushed in for about 15 seconds. If the pilot
burner fails to stay alight, repeat the lighting procedure only now
keep the control knob pushed for a little longer.
If the gas control knob “A” is turned to' 'a safety lock prevents
it being turned on again until 3 minutes have elapsed.
Make sure that the pilot is alight and stable, see diagram 7.2 for
the approximate flame length. 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 the 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 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 anti-clockwise to
decrease, see Data Table or refer to “L” Data Label for setting
pressure. After adjusting replace cover.
If any doubt exists, the gas rate should be checked at the meter.
This should be in the range of :- HIDEAWAY 120B 3.5m 3 /h to
4.2m 3 /h (125 to 148 ft 3 /h)
Stick the self-adhesive arrow indicator, from the loose items
pack, to the data label against the rating the boiler is going to be
set to.
Allow the water system to reach maximum working temperature
and examine for water soundness. The system should then be
turned off and drained rapidly, whilst still hot, to complete the
flushing process.
The system should then be filled again, vented and examined
for water soundness.
