8. FULL OPERATING CHECKS
8.1 Recheck Control Settings
Now that all the ceramic fuel effects are in position, the
control operation must be fully rechecked.
•
Make sure that the isolating valve is open.
•
Depress the control knob and turn anti-clockwise
partially towards the “PILOT/IGN” position. A spark
should be generated at the pilot while turning. The spark
should ignite the pilot. Check that the pilot flame is
visible.
•
When pilot ignition has been achieved, keep the control
knob depressed for approximately ten seconds to allow
the thermocouple probe to warm up and then release it.
If the pilot does not remain alight, ensure that the pilot
orifice is clear.
•
When the pilot is alight and stable, partially depress the
knob and turn to “LOW”. The pilot should then light the
main burner at its low setting. There may be a delay of
up to four seconds between the pilot lighting and ignition
of the gas at the main burner. This is normal and is due
to the time required to fill the main burner compartment
with sufficient gas for ignition.
•
When the burner is operating properly, partially depress
the knob and gradually turn it anti-clockwise. The
burner flames should gradually increase until the knob
reaches the “HIGH” position.
•
Partially depress the control knob and turn back the
“PILOT/IGN”. The main burner flames should be
extinguished but the pilot should remain alight.
•
Partially depress the control knob and turn to “OFF” the
pilot should be extinguished.
8.2 Check For Spillage
A spillage check must be made before leaving the
installed appliance with the customer. Make this check
with the appliance fully installed with the ceramics and
front castings in position.
•
Close all doors and
windows in the
room containing
the appliance.
•
Light the appliance
and turn the control
knob to “
HIGH
”.
•
Leave the appliance
on for five minutes.
•
Place the smoke
match into the
appliance canopy
(See Fig.19)
•
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
smoke is still not drawn into the appliance,
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.
8.3 Flame Supervision & Spillage Monitoring System
This 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.
This monitoring system must not be adjusted, bypassed or put
out of operation.
This monitoring system, or any of its parts, must only be
exchanged using Wonderfire Authorised parts.
