TESTING AND COMMISSIONING
Turn on and test the gas supply up to the fire for any leaks, in accordance with the current edition of
BS 6891 (natural gas installations) or the current edition of BS 5482 pt1 (propane installations).
OPERATING THE APPLIANCE
The control knob is located on the lower right hand side of the
outer case. It is marked as shown in figure 7.
The pilot is visible behind the left hand side of the burner. Push
the control knob in fully and turn anti-clockwise through both of
the SPARK positions, keeping fully depressed, hold there for a
few seconds. If the fire has not been used for some time, hold
the knob in this position for longer, to allow any air in the pipes
to be purged. Continue turning anti-clockwise through the
spark clicks to the nine o’clock position, ensuring the pilot has
lit. If not, return the knob clockwise, and repeat. When the pilot
lights after one of the two sparks, keep the knob depressed in
the nine o’clock position for approximately ten seconds. Now
release the knob and the pilot should stay alight. If the pilot is
extinguished during use, wait three minutes before repeating
the ignition procedure. To achieve the HIGH setting, push the
control knob in slightly and continue turning anti-clockwise to
the high position. The main burner should light after a few sec-
onds. To decrease the setting to LOW, push the knob in slightly and turn the control knob clockwise to
the low setting. To turn to the pilot only position from the HIGH or LOW positions, press the control
knob in, and return to the nine o’clock position and release. To turn the fire OFF, keep the knob pressed
in, return to the off position and release.
SPARK FAILURE
The gap between the spark electrode and the pilot should be 3.5 - 4.5mm to produce a good spark.
There should be no need to adjust this. If under any circumstances the piezo electric spark fails, the
pilot cannot be lit manually.
SETTING PRESSURE
The pressure test point is located on the inlet restrictor elbow in the centre of the burner as
shown in figure 8.
Release the pressure test point screw, and attach a pressure gauge. Light the fire on the
HIGH setting. To commission the appliance, the operating pressure must be in accordance
with the figures stated in section 2.0 of these
instructions. The fire is factory set to achieve
the correct flow rates at the specified inlet pres-
sure.
Any significant variation in the operating pres-
sure could indicate a supply problem. If the
inlet pressure is too high, the gas supply
meter/governor may be set incorrectly.
This should be checked with the fire running
and if necessary reset by the gas supplier. If
the operating pressure is too low, then check
the meter/governor pressure with the appliance
running. If this is less than the inlet pressure
stated in section 2.0 of these instructions it will
need to be reset by the gas supplier. If the inlet
pressure is too low, but the meter/governor
pressure is acceptable, then a problem in the
supply pipework is to be suspected.
Upon satisfactory checking of the inlet pressure, turn the fire off, disconnect the pressure
gauge and refit the test point screw. Light the fire and check for gas soundness. In the event
that the inlet pressure is not in accordance with the figures stated in the data section of these
instructions, the appliance must not be commissioned, and the problem investigated and rec-
tified.
