Connecting the Appliance to the Gas Supply
The gas supply can be connected to the appliance by a concealed fitting from the rear. In all installation conditions the gas
connection should be provided using 8mm (O/D) copper tubing. If the concealed installation method is chosen, there are
three optional entry points at the rear/side of the appliance. The relevant ‘knock-out’ entry point should be removed to
allow the gas supply to enter the appliance.
No soldered joints
should be used with the firebox of the appliance. The blind
grommet which is supplied in the standard fitting pack should be used to close up the knock out hole—simply cut a small
cross with a sharp knife in the centre of the grommet—this will then seal around the gas pipe to provide a tight seal.
Under no circumstances
should this gas entry hole be
left open
and
unsealed
as this can result in
flame reversal
and can
cause
damage
to the appliance.
Should this occur the warranty to this appliance will be rendered void.
Before connecting the gas supply to the appliance a gas soundness test should be performed to ensure that the existing
pipe work in the property is sound.
The burner tray can now be reinstalled into the firebox.
The gas connection should be made to the appliance by the 8mm restrictor isolation valve supplied with the appliance.
Install the ceramics on to the appliance according to these instructions—see page 14.
Test the operating pressure of the appliance by attaching a pressure gauge to the test point of the appliance. This
connection should take place when the appliance is OFF. Ensure that gas is turned on at the gas meter and purge the air
from the appliance by:
MANUAL CONTROL UNITS: Rotating the control to the (IGN) position and push in. Every 10 seconds the knob should
be rotated back to the (OFF) position and back to the IGN position to generate the spark at
the electrode Check that the spark is being generated correctly at the pilot assembly.
Continue with this procedure until the air is purged from the appliance and the pilot is lit.
Once lit hold the valve pushed in for up to 30 seconds. Once the pilot is established and
secure turn the control knob anti-clockwise to the (HIGH) position. Allow the appliance to
run for a minimum period of 5 minutes. Next check that the inlet pressure to the appliance is
at 20 mbar ±1 mbar.
SLIDE CONTROL UNITS:
Push down the control lever fully to the (IGN) position and hold. The spark generator
should spark continuously, ensure the spark is being generated correctly at the pilot
assembly. Continue with this procedure until the air is purged from the appliance and the
pilot is lit. Once lit hold the lever pushed down for up to a further 30 seconds. Once the pilot
is established and secure allow the lever to rise to the (LOW) position then lift the lever to
the (HIGH) position. Allow the appliance to run for a minimum period of 5 minutes. Next
check that the inlet pressure to the appliance is 20 mbar ±1 mbar.
Check the operation of the appliance according to these instructions—see page 13.
Check the clearance of combustion products
SPILLAGE TEST:
To check for satisfactory clearance of products of combustion, close all doors and windows and
leave the appliance burning on HIGH for five minutes. Insert a lit smoke match just into the top of the fire
opening and move it left and right, all the smoke must be drawn into the flue. If spillage occurs allow a further 5
minutes and repeat the test. If spillage still occurs turn off the appliance and seek expert advise to expert
advice. If an extractor fan is situated in the room the spillage test should be repeated with the fan running. If
there is a connecting room with an extractor fan the test should be repeated with all the doors to that room
open and the extractor fan running.
