PART 9: CHECKS

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 and that the electrical
power supply is on (the indicator light should glow).
•
Press and hold in the "on" switch. Within two seconds, the Fan should start and the
indicator light should go out.
•
Release the "on" switch. The fan should continue to run.
•
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. 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 lit, 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 to "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.
•
Press the "off" switch to turn off the fan (the indicator light should glow).
