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.
1.
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.
2.
After checking, turn off the
appliance. Remove the pressure
gauge and replace the test point
sealing screw.
3.
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.
1.
Close all doors and windows in the room containing the appliance.
2.
Light the appliance and turn the control knob to the ‘HIGH’ position.
3.
Leave the appliance on for five minutes.
4.
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 (See page 6 - point 4) 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.
5.
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;
