6. Check Gas Pressure & Operation Of Fire - Page 10
.
7. Test For Spillage - Page 10
The test point screw is located on the left hand side of
the controls assembly near the gas tap.
a) Remove the pressure test point screw and connect
a pressure gauge.
b) Push in and turn the control knob anti-clockwise to
the '
' (ignition/pilot) setting and the pilot should
light. Keep the knob pushed in for 10 seconds then
release, the pilot should remain alight.
It may be necessary to repeat this operation several
times before all the air is purged from the line. Push
in and turn the knob clockwise back to ' OFF '
between each attempt.
c) Turn the control knob to setting ' HI '.
d) Check the burner pressure, it should be:-
17.3mbar ± 1.0mbar (6.9in w.g. ± 0.4in w.g.).
This pressure will only be obtained if the incoming gas
pressure is 20mbar (8in w.g.).
Check the size of the pilot flames, when lit the pilot flame
envelope should just cover the electrode tip and
thermocouple. If the flame is not as described, replace
as shown in Section 11.2.
e) Push in and turn the control knob through to 'OFF'.
f)
Disconnect the pressure gauge, re-fit the pressure
test point screw and test for gas soundness
1. Fire Only
a) Close all doors and windows, re-light the fire (pilot
now only visible in a reflected form, see Fig.12).
Then turn to the ' HI ' setting.
b) After 5 minutes light a smoke match and position
centrally as shown in Fig.9. The smoke should be
drawn into the flueway.
c) If in doubt, a re-check can be made for up to a total
of 15 minutes after lighting the fire.
d) If the fire shows a pronounced tendency to spill,
remove the fire and check that the spigot is securely
connected. Re-fit the fire and re-perform the test.
e) If the test still shows spillage, DISCONNECT THE
FIRE AND SEEK EXPERT ADVICE.
f)
If there is an extraction fan in any room, this must be
turned on and any doors between it and the fire left
open, re-perform the test.
2. Fire & Boiler
Switch on the boiler and repeat the full test shown
above.
If the tests are successful, turn the fire off and complete
the installation.
