15. SPILLAGE & FLAME SUPERVISION CHECKS
15.1 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
“HIGH”.
3.
Leave the appliance on for five minutes.
4.
Place the smoke match into the appliance canopy
(See figure 39).
5.
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 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 8.5), remove the restrictor,
reseal the appliance and retest. If smoke is still not drawn into the appliance,
disconnect
the appliance and seek expert advice.
6.
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.
15.2 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 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.
