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 9). 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 flue
restrictor is fitted then remove the restrictor and repeat the above 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.
Flame supervision and spillage monitoring system.
The pilot unit incorporates a system that will automatically shut off the gas supply if
the pilot flame goes out. Check that the system operates properly as follows;
