Release the button. The button should
automatically spring up to the low heat
position. If the flames go out at this

CHECK REFERENCE PRESSURE
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 situated below the bottom
right corner of the burner unit (See
figure 42). Check the pressure with
the appliance alight and set at maximum
output.
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 and test around the sealing
screw for gas soundness with a suitable
leak detection fluid.
