PRESSURE TESTING (SEE FIG. 16).
The pressure test point is situated at the injector of the rear burner (rapid).
Fit the pressure gauge onto the burner injector/pressure test point.
Place the semi-rapid burner cap into position on the hob (align holes with the burner electrode
and thermocouple tip). Light the burner by pushing in the appropriate control knob, and turning
anti-clockwise to the full on position. Press the knob until the gas ignites, then hold for a further
3 seconds.
With the semi-rapid burner alight, push and turn the control knob for the rear (rapid) burner to
the full flame position. Hold the control knob down and take the pressure reading.
For Natural Gas appliance, the pressure should be nominal 20mbar (8 inches water gauge).
For L.P.G. appliance (propane) the pressure should be 37mbar (14.8 inches water gauge).
Turn off the taps, disconnect the pressure gauge and refit burner head.
