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 at the inlet elbow 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.

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.
Figure 20 Spillage check
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 & 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 Valor Authorised parts.

FULL OPERATING CHECKS

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.20)
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
