Check Reference Pressure .
The appliance is pre-set to give the correct setting pressure as shown in part 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 32). Check the pressure with the fan on, the
appliance alight and set at maximum input.
After checking, turn off the appliance. Remove the pressure gauge and replace the test
point sealing screw. Relight the appliance. Turn to the maximum input position and
test around the sealing screw for gas soundness with a suitable leak detection fluid.
Do
not use leak detection sprays on this appliance. Sprays may affect the operation of
electrical components. Keep all liquid detection fluids clear of electrical components.
