CONNECTING THE GAS SUPPLY
Once the stove is in place it is then possible to
connect the gas supply. The gas supply point is
located centrally at the rear (as show in fig.7) and
should be connected in accordance with the follow-
ing requirements.
Fig. 7
Check that the appliance is suitable for the gas
supply; refer to data labels on packaging and/or the
stove data label for the gas type.
The gas installation must be in accordance with the
current issue of BS6891.Gas supply pressure at the
fire should be
20
mbar for
natural gas
&
37
mbar
for
LPG
.
The gas supply should be connected with the 12mm
fitting and olive supplied with the stove.
A maximum pipe run of 1.5 meters (or 5 feet)
should be adhered to. Copper tubing may be used
provided a distance of 25mm is maintained
between pipe-work and any surface of the stove.
The gas service tap (supplied) should be fitted adja-
cent to the fireplace to enable safe removal of the
appliance for servicing. After fitting the supply,
operate the gas tap (supplied) and check all joints
up to the termination of the supply pipe for gas
tightness using a soap/water solution and the pres-
sure drop method.
To check the pressure to the burner.
This must be
carried out with all other gas appliances operating
at maximum. To check the pressure to the burner it
is necessary to ignite the appliance and set to 'high
rate'. (See pressure test sequence).

20 mbar for Natural Gas or
37 mbar for LPG
Step 4
. If any adjustment is required, use the brass
screw located between knob B and knob A on the
front of the valve, and adjust accordingly to the
indication symbol marked upon the valve body.
