Gas Convector
The positions of the control valve are
depicted on the control panel fitted
around the control knob.
If the main burner or pilot light are
extinguished for any reason do not
attempt to re-light the pilot within three
minutes.
The off position is self explanatory -
preventing any gas from passing through
the control valve to either the pilot burner
or to the main burner.
By pressing the control knob in it is
possible to turn it anti-clockwise. The first
function is to turn on the gas to the pilot,
this occurs just before reaching the pilot
position. (If the fire has not been lit for
some time it may be necessary to hold
the knob in this position for some seconds
to clear the air from the pipe and allow
gas to reach the pilot burner). Once gas
is available at the pilot, continual rotation
anti-clockwise will cause the piezo ignitor
to spark. This is accompanied by a click
at the valve, and should result in the pilot
burner igniting. This should be verified by
looking at the left-hand side of the fire
tray, behind the front coal piece.
Once the pilot is lit the control knob
should continue to be pressed in for 10
- 20 seconds. In this time the pilot flame
will have heated the flame supervision
thermocouple sufficiently to operate a
hold on magnet within the valve. The knob
should then be turned so that the pointer
is approximately horizontal. This allows
gas at a low rate to enter the burner and
be ignited by the pilot flame. Once the
fire has fully cross lit, allow approximately
15 seconds at this setting to allow the
flame to fully establish before setting to
any level between Maximum and Minimum
by adjusting the control knob accordingly.
To turn off the main burner, turn the
control to MIN - press the knob gently
until it will turn clockwise to the pilot
position. To turn off the pilot press knob
and turn to off.
If burnback occurs underneath the
burner, turn knob to the off position.
Then re-light the fire. If this problem re-
occurs switch off unit and call your gas
installer.
Thus the sequence is:
A. To Light the Fire
1
From off press the control knob in
and turn slowly anti-clockwise.
2
When the ignition click occurs,
check that the pilot is lit (if not
repeat 1 & 2).
3
Hold knob in for 10 - 20 seconds.
4
Release knob and check pilot
remains alight.
5
Turn knob until pointer is horizontal.
The fire should then ignite .
6
Let fire fully cross ignite and allow
a p p rox i m a t e l y 1 5 s e c o n d s .
7
Adjust flames to required level
without pressing knob.
B . To Extinguish the Fire
1
Turn control knob clockwise to
minimum position.
2
Press knob gently until able to
continue turning clockwise to pilot.
3
To extinguish the pilot, press knob
and turn to off, although it is in order
to leave the pilot permanently lit.
