Testing Supply Pressure
1.
Gas pressure at the appliance is measured via the rearward test nipple (Test nipple
‘A’ in diagram 8) on the left-hand side of the control valve. (Turning the screw
approximately half a turn anti-clockwise with a small flat-bladed screwdriver
opens the test point.)
ALWAYS CLOSE TEST POINTS AFTER USE!
2.
The gas pressure at the appliance is measured with the appliance running at
full
rate
. (For information on how to achieve ‘full rate’ read, ‘
Adjusting between High and
Low Output Settings’
in the ‘Lighting the Appliance’ section of the User Instructions.
Burner gas pressure should be:
Natural Gas
@ 19mBars
LPG
@ 36mBars
3. The mains supply pressure coming into the appliance can be checked by using
Test point ‘B’, shown in diagram 8.
