Installing the Appliance To install the appliance it is necessary to have a gas supply and an electrical supply close to the proposed siting of the appliance. If the BE MODERN HARMONY surround and hearth is being used it is advisable that the services are laid as shown in Fig.3. In all applications the appliance must be fixed in position at the top at the gather by the two tabs provided and at either of the additional fixing positions provided in the base or through the rear panel of the hot box. Gas Supply In most cases it will be preferential for the gas supply to be concealed which would mean the supply entering the appliance from either the left or right hand rear corners of the hot box, four knock-out holes are provided for entry of the supply pipe. In many instances this would necessitate the gas supply being fed through a wall or solid floor etc. Therefore the installer is reminded of the requirements of BS6891 1988 dealing with enclosed pipes. This standard requires that when a gas pipe is fed through a wall the pipe should be enclosed in a fight sleeve to protect against failure caused by movement. It shall be constructed to prevent passage of gas either between the pipe and the sleeve and the sleeve and the wall. It is desirable for the appliance to be installed with a means of isolating the gas supply to the burner for the occasions when the appliance requires servicing thus preventing a need to turn off other appliances in the household. A recommended method is to fit a restrictor elbow or isolation cock as shown in Fig.4. This will require a standard 8mm to 1/4 BSP restrictor elbow with 8mm compression to 1/4 BSP tapered stud coupling. A short length bundy pipe is supplied to enable a connection to be made between the restrictor elbow and the combined pressure test/inlet elbow fitted to the burner assembly. For this purpose a formed section of 8mm bundy pipe is supplied that will enable a connection to be made to either the left or right hand rear corner, by cutting the piece as required. Connection to the burner assembly should only be made using bundy pipe and compression fittings; copper tube or capillary joints must not be used within the appliance. Electrical Supply Wiring external to the appliance must be in accordance with the IEE wiring regulations and any local regulations. The appliance it supplied for 220-230V ~ 50Hz single-phase operation. Fuse rating is 3 amp. A fused double pole switch or a fused double pole switched spur with a contact separation of at least 3mm in all poles may be used serving only the appliance. It s essential that the electrical supply in the property should be properly earthed in accordance with current IEE regulations.
