2 9 S E C T I O N 1 2Once the fire has been lit for 5 minutes, turn the gas OFF at the isolating elbow.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 closewithin the 3-minute period.Turn OFF the appliance and the gas supply and refit the pressure test point sealingscrew.FLUE SPILLAGE MONITORING SYSTEMRemote controlled 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 besuspected, if a door or window has been opened creating a draught, then pilotdisturbance 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 tocheck and rectify any problem).The thermocouple connection into the back of the gas control valve may also haveworked 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 ifit continues to fail a spillage test.The aeration hole of the pilot must be carefully cleaned out on each annual service toensure continued function of the ODS.The spillage monitoring system shall not be adjusted, modified, or put out of operationby the installer.Any spare parts fitted MUST be of a type supplied for the purpose by the appliancemanufacturer.If the fire is not spilling, then further guidance should be sought, using theTroubleshooting section as a guide.
