FULL OPERATING CHECKS
10.1
RECHECK CONTROL SETTINGS
Now that all the ceramic fuel effects are in position, the
control operation must be fully rechecked.
10.1.1
Make sure that the isolating valve at the inlet
elbow is open.
10.1.2
Depress the control knob and turn
anticlockwise partially towards the “PILOT/IGN” position
until some resistance is felt. Keep depressed at this
position to purge air from the system then, while keeping it
depressed, turn fully to the “PILOT/IGN” position. A
spark should be generated at the pilot while turning. The
spark should ignite the pilot.
10.1.3
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.
10.1.4
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.
10.1.5
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.
10.1.6
Partially depress the control knob and turn
back to “PILOT/IGN”. The main burner flames should be
extinguished but the pilot should remain alight.
10.1.7
Partially depress the control knob and turn
to “OFF”. The pilot should be extinguished.
10.2
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 ceramic fuel effects and front surround in
position.
10.2.1
Close all doors and windows in the room
containing the appliance.
10.2.2
Light the appliance and turn the control
knob to “HIGH”
10.2.3
Leave the appliance on for five minutes.
10.2.4
Place the smoke match tube into the convection box
at the right hand side and immediately below the black top
cross member. Angle it at approximately 45° to the
horizontal.
Insert the tube so that the neck of its flared end touches
the inside surface of the edge of the cross member (figure
23).
Keeping the neck of flared end in contact with the edge of
the cross member, slide the tube to the left until you feel it
enter the notch in the edge of the cross member. Make
sure that the tube is pointed upwards at 45º to the
horizontal.
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
6.5), remove the restrictor, reseal the appliance and retest.
If smoke is still not drawn into the appliance disconnect the
appliance and seek expert advice.
10.2.5
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.
10.3
FLAME SUPERVISION & SPILLAGE
MONITORING SYSTEM
This pilot unit incorporates a system which 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;
10.3.1
Light the appliance. Set at the “HIGH”
position and leave for one minute.
10.3.2
Turn back to “OFF” to extinguish the pilot.
Note the time when the pilot goes out. Listen for a snap sound
at the gas tap. Note the time when the sound is heard. This
sound is caused by an electromagnetic valve shutting off the
gas supply through the tap. The valve is located in the body
of the tap. The valve should operate within 60 seconds of the
pilot going out. If the valve does not operate within this time
limit do not allow the appliance to be used until the fault
has been corrected.
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 Valor authorised parts.
