SETTING PRESSURE (continued)
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 problem 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 pressure.
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. If a grommet seal has been left out
of the firebox then this also will also cause intermittent shutdown (recall your installer to fit). 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.
TESTING FOR SPILLAGE
Close all doors and windows to the room containing
the appliance. Let the fire run on HIGH for five
minutes. Take a smoke match, light it, and using a
smoke match tube, hold it at the top edge of the fire
opening, 25mm down and 25mm in. Starting 50mm in
from either side, run the smoke match across the
opening. All the smoke should be drawn away into the
flue. Any smoke returning into the room indicates that
spillage is occurring. If the initial test fails, run the fire
for a further 10 minutes and repeat the test. When the
test has been completed satisfactorily, repeat with any extractor fans in the premises running on the highest
setting, and any communicating doors open. Finally, repeat with all doors open.
NOTE: If spillage is still indicated after undertaking all of the above, there may be a problem with the flue setup,
or insufficient ventilation is present.
If the problem cannot be rectified immediately, then expert advice should be sought. Inform the user, disconnect
the fire, and attach an explanatory label.
