16.2 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.
The smoke match should be placed
horizontally into the hotbox at the right hand
side (See figure 33).
The installation is satisfactory if the smoke is
drawn into the appliance.
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 inspect the sealing to the
fireplace surround. If the sealing is
satisfactory but the appliance is installed with
the flue restrictor (See section 9 point 4) remove the restrictor, reseal the appliance
and retest. If smoke is still not drawn into the appliance
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
.

The pilot unit incorporates a system that will automatically shut off the gas supply if
the pilot flame goes out or if there is insufficient oxygen due to spillage or lack of
ventilation.
Check that the system operates properly as follows;
Light the appliance. Set at the ‘HIGH’ position and leave for one minute.
Turn back to ‘OFF’ to extinguish the pilot.
Note the time when the pilot goes
out.
Listen for a snap sound at the gas valve.
