2.3 GAS TIGHTNESS AND INLET PRESSURE (MANUAL CONTROL
MODELS)
a)
Remove the pressure test point screw from the inlet elbow and fit a
manometer.
b) T
urn on the main gas supply and carry out a gas tightness test.
c) Depress the control knob and turn anti-clockwise to the position marked
pilot. Hold in the control knob for a few seconds to purge the pipe work
then press the igniter button. The burner should light, continue to hold
the control knob for a few seconds then turn to the full-on position.
d) Check that the gas pressure for Natural Gas (G20) models is 20.0 mbar
(+/- 1.0mbar) 8.0 in w.g.(+/- 0.4 in w
.g.) or for LPG models 37.0 mbar
(+/- 1.0mbar) 14.8 in w.g.(+/- 0.4 in w.g.)
e) Turn off the fire, remove the manometer and refit the pressure test point
screw. Check the pressure test point screw for gas tightness with the
appliance turned on using a suitable leak detection fluid or detector
.
2.4 GAS TIGHTNESS AND INLET PRESSURE (SLIDE CONTROL
MODELS).
a) Remove the pressure test point screw from the pressure test point and
fit a manometer.
b) T
urn on the main gas supply and carry out a gas tightness test.
c) Depress the control lever to the position marked pilot. Hold down the
