ignition’ position. The main burner should extinguish but the pilot should remain alight.
Depress the control knob slightly and turn back (clockwise) to turn OFF.
This will extinguish the pilot.
Inlet pressure check.
The appliance is pre-set to give the
correct heat input at the inlet
pressure shown in section 2 of this
manual. No adjustment is
necessary.
Check the inlet pressure by
fitting a pressure gauge at the test
point. The test point is on the inlet
‘T’ connector (See figure 8). 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.
Check for spillage.
Close all doors and windows in the room containing the appliance.
Light the appliance and turn the control knob to the ‘HIGH’ position.
Leave the appliance on for five minutes.
A smoke match should be placed close to base of the diverter box. The
installation is satisfactory if the smoke is drawn into the appliance/ flue way. Do not
use a lighted match or a naked flame.
If the smoke is not drawn into the appliance leave the appliance alight at the
maximum setting for a further ten minutes and then repeat the test. If the smoke is
still not drawn into the appliance then disconnect the appliance and seek expert
advice.
If the above test is satisfactory open all internal connecting doors, hatches, etc. in
the room. Keep all doors and windows that open to the outside of the building closed.
Recheck for spillage as above. If an extractor fan is installed in the same room as the
appliance or a connecting room, check that spillage does not occur with the fan
operating and all doors and other openings between the fan and the appliance open.
If the smoke is drawn into the appliance, continue with the installation. If the test is
not satisfactory disconnect the appliance and advise the customer of the cause
of failure.
