-
When the pilot has lit, keep the right hand control knob depressed for a few
seconds to allow the pilot flame to stabilise then release it. If the pilot does not remain
alight ensure that the air has been purged.
-
Partially depress the right control knob and turn to the main burner position
marked
.
-
The left-hand knob is for burner flame adjustment. In its fully clockwise position it
turns the main burner off. Depressing top half of the rocker switch should cause the
flame control knob to rotate anticlockwise direction. This should light the main burner
and gradually increase the flame height. The maximum flame height should be
achieved when the bar of the flame control knob is pointing vertically upward.
-
After checking up to maximum flame height, depress the bottom half of the rocker
switch until the main burner is extinguished.
-
The flame control rocker switch does not have to be operated every time the fire is
lit or turned off. The main burner setting will remain at its previously chosen position
enabling the customer to use the right hand control only to ignite the burner at that
setting and to turn the fire off.
-
After checking turn the right hand knob to off. Depress the control knob partially at
the pilot position (
), turn clockwise to off (
•
) and release the knob. If any
resistance is felt when turning, release the downward pressure on the knob before
continuing to turn.
13.3 Checking inlet pressure.
The burner aeration is non-adjustable. The appliance is preset to give the correct heat
input on Natural Gas at 20 mbar (8in w.g) inlet pressure and no further adjustment is
necessary. The burner pressure should be checked at the pressure test point located
on the inlet ‘T’ connector (See figure 33). The pressure check should be carried out
using a calibrated pressure gauge after removing the test point screw. The fire should
be alight and the left hand control
knob at its fully anticlockwise setting
(Maximum flame height). The
pressure setting should be within
the limits shown in section 2 of this
manual (Appliance data and
efficiency). After checking the
pressure, turn off the fire, remove
the pressure gauge and replace the
pressure test sealing screw. Relight
the fire and test all gas joints for
soundness using a suitable leak
detection fluid.
