Unit installation
!
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 upwards.
!
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 29). 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 3 of this
manual (Appliance data). 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.
