-
clockwise 2 or 3 turns and then placing pressure gauge
tubing over the test point. Gauge should read as described
on the chart below. Check with main burner is operating on
'HI'.
Outlet pressure can be checked the same as above using
-
screw (B). Gauge should read as described on the chart
below. Check that main burner is operating on 'HI'.
AFTER TAKING PRESSURE READINGS, BE SURE TO TURN
-
SCREWS CLOCKWISE FIRMLY TO RESEAL. DO NOT OVER
