Gas Supply Connections
The appliance is supplied with a 8mm Bundy pipe and a 8mm compression
elbow to allow easy connection to the mains gas supply. This supply gas pipe
should incorporate a gas service isolation tap that is situated within 1 metre of
the application.
Diagram 7 shows the 8mm Bundy
pipe being fitted to the gas inlet
on the valve. The compression
joint is tightened with a 12mm
open-ended spanner.
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
