After a further 3 minutes turn the gas supply ON again, if the gas has stopped flowing, the Flame
Supervision Device (FSD) is operating correctly.
Always check that the gas has stopped flowing even if you hear the FSD valve close within the 3-minute
period.
Turn OFF the appliance and the gas supply and refit the pressure test point sealing screw.
SECTION 12: FLUE SPILLAGE MONITORING SYSTEM
Royal fires are 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, recalls 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
