FUEL BED LAYOUT
Please see the relevant section of the user instructions.
FITTING THE FIREFRONT
Place the decorative firefront in front of the fire and slide the ashpan door into place. The firefront shown in these instructions may be dif-
ferent to the one supplied with the appliance.
GAS CONNECTION
Purge the gas supply thoroughly to remove air and dirt/debris BEFORE connection. Now disconnect the inlet restrictor elbow from the inlet
pipe. Connect the previously installed gas supply to inlet restrictor elbow, and re-fit the restrictor elbow to the inlet pipe of the appliance.
If using an across hearth connection, ensure the decorative fireframe and firefront will clear the supply route.
If the data/control plate is not already fitted, attach with two screws, ensuring the control knob is free to be depressed fully.
TESTING AND COMMISSIONING
Turn on and test the gas supply up to the fire for any leaks, in accordance with current edition of BS6891.
When the appliance is first used, protective oils coating the firebox may burn off. It is advisable to ventilate the room during this period for
at least one hour.
OPERATING THE APPLIANCE
The pilot is visible through the left hand side of the matrix. Rotate the coals for good viewing. Push
in and turn the control knob to the SPARK position, and hold there for a few seconds.
Continue turning anti-clockwise through the spark click to the PILOT light position, ensuring the
pilot has lit. If not, return the knob clockwise, and repeat.
When the pilot lights after the spark, keep the knob depressed 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 seconds.
To decrease the setting to LOW, turn the control knob clockwise to the low setting.
To turn to the PILOT position from the HIGH or LOW positions, press the control knob in, and return to the pilot 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 electric spark fails, the pilot may be lit manually by proceeding 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.
SETTING PRESSURE
Remove the screw from the pressure test point.
The ttest ppoint iis ssituated oon tthe m
main iinjector ppipe
Attach a U gauge. Light the fire on the HIGH setting. The setting pressure should
be in accordance with the figures stated on page 2 of these instructions. The fire
is factory set to achieve these pressures, and any significant variation could indi-
cate 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. If the
pressure is too low, then check the meter governor pressure with the appliance
running. If this is incorrect it will need to be reset by the gas supplier.
If the setting pressure is too low, but the meter pressure is acceptable, then a prob-
lem in the supply pipework is to be suspected. This will be dirt and debris, kinked or inadequate size pipes, restriction in a fitting or solder
flashing across a joint. (NOTE: you will not get an accurate reading of the inlet pressure with a pressure gauge on the end of the supply pipe
- this is the static pressure in the system. You must use a T piece and measure the supply pressure with the fire on High - the dynamic pres-
sure). Refit and tighten the screw into the pressure test point when the test is complete.
FLUE SPILLAGE MONITORING SYSTEM
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 ther-
mocouple connection into the back of the gas control valve may also have worked loose during installation, simply get the installer to tight-
en. 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.
