The spark gap (shown in figure 19) between the spark electrode and the thermocouple
should be 3.5 - 4.5mm to produce a good spark.
There should be no need to adjust this.
If under any circumstances the electric spark fails, the pilot may be lit manually by proceed-
ing with the ignition sequence as previously described, and after turning the control knob
through the spark position, the knob should be held in and the pilot lit with a taper.
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 pressure.
Any significant variation in the inlet pressure 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 sup-
plier. If the inlet 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
rectified.
Slide control models : The pressure test point is located directly above the gas valve in the centre of the burner.
Remote control models : The pressure test point is located on the right hand side of the burner, between the burner legs.
Release the pressure test point screw, and attach a pressure gauge. Light the fire on the HIGH setting. To commission the appliance, the
burner pressure must be in accordance with the figures stated in section 2.0 of these instructions.
The fire is factory set to achieve these pressures and any significant variation could indicate a supply problem. If the pressure is too high,
the gas supply meter may be set incorrectly. This should be checked with the fire running and if necessary reset by the gas supplier.
Upon satisfactory checking of the burner 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 burner pressure is not in accordance with the figures stated in the data sec-
tion of these instructions, the appliance must not be commissioned, and the manufacturer should be contacted for guidance.
This fire is fitted with a flue spillage safety device (ODS). If the fire shuts down during use for no apparent reason then several things
may be suspected. If a door or window has been opened creating a draught, then pilot disturbance is the problem, and removal of the
draught should resolve this. The gas pressure reaching the fire must also be checked (again, recall your installer to check and rectify any
problem). The thermocouple connection into the back of the gas control valve may also have worked loose during installation, simply
get the installer to tighten. If pilot disturbance is not the cause, then the ODS safety system may be in operation. Switch the appliance
OFF, check the flue and carry out any remedial work required. Relight the fire and carry out a spillage test.
DO NOT allow the appliance to be used if it continues to fail a spillage test. The aeration hole of the pilot must be carefully cleaned out
on each annual service to ensure continued function of the ODS.The spillage monitoring system shall not be adjusted, modified, or put
out of operation by the installer. Any spare parts fitted MUST be of a type supplied for the purpose by the appliance manufacturer. If the
fire is not spilling, then further guidance should be sought, using the Troubleshooting section as a guide..
