• Wiring inside this appliance may be at 240 V potential.
WARNING
• Do not test for gas escapes with an open flame.

TO CHECK AND SET BURNER PRESSURES

• Refer to Data Plate and the Technical Specification section in this manual.
• Connect the CAT5 Cable to the control receiver in the rear right hand side of the front panel
assembly. Don't fit front panel assembly to the appliance yet.
•
Loosen the outlet test point screw and attach manometer to the test point. The outlet test point is on
the right hand side of gas control (shown below).
• Turn the appliance 'ON'. Adjust to the 'high' flame setting. Check the high pressure setting adjust as
detailed below. Adjust to the 'low' flame setting. Adjust as detailed below if required.
If adjustments are necessary, remove Cap C. The pressure adjustment screw and nut are on the front side of the
gas control as shown and should be set to the pressures on the appliance data-plate.
High Pressure Setting:
• Use a 10 mm spanner to turn nut A. Turning
clockwise increases the outlet pressure whilst
turning anti-clock wise decreases the outlet
pressure.
Low Pressure Setting:
• Turn off the power to the POV by disconnecting
the POV test connection in main harness and
keeping Nut A stationery.
• Use a screwdriver for setting Screw B. Turning
clockwise increases the outlet pressure whilst
turning anticlockwise decreases the outlet
pressure.
• Replace Cap C after pressure adjustments.
• Reconnect the POV test connection.
•
Burner aerations are factory preset and cannot
be adjusted.
To ensure the correct operation of the POV it is necessary that the plastic Cap C
is returned to its original location.
WARNING
•
After checking the pressures, turn the appliance off, remove manometer and tighten the test point
screw.
•
Turn the appliance on and off a few times to confirm correct ignition and operation.
•
When satisfied that the appliance is igniting and operating correctly, refit the burner cover assembly
and front panel assembly.

It may take approximately 2 hours of operation for the black coals/river stones to achieve their full
flame pattern and glow.
• During the initial burn in period, some smoke and smell may be emitted. The appliance should be
run on the high position in a well ventilated room until these dissipate.
