The appliance is pre-set to give the correct heat input at the inlet pressure shown in
section 1 of this manual. No adjustment is necessary. Check the burner pressure by
fitting a pressure gauge at the test point. The test point is on the pipe connecting the
gas tap to the lower injector. Check the pressure with the appliance alight and set at
maximum output (Control knob position 4).
After checking, turn off the appliance. Remove the pressure gauge and replace the
test point sealing screw. Relight the appliance. Turn to the maximum output position
