1.0 Introduction - Page 4 1.1 Description 1. The Baxi Belmont 2 and Wentworth Classic Fan Flue are live fuel effect inset gas fires designed to be used on Natural Gas only at a setting pressure of 20 mbar. 2. The appliance is designed to give a maximum heat output of 3.0 kW (10,236 Btu/h). 3. The fire is controlled by a knob which is positioned behind the controls access door on the fender assembly (Fig. 1).
1.0 Introduction - Page 5 1.3 Installation 1. The appliance is suitable for installation only in G.B. and I.E. and should be installed in accordance with the rules in force. For Ireland install in accordance with l.S.813 ‘installation of Gas Appliances”.

3.0 Site Requirements - Page 7 3.1 Location 1. The Baxi Belmont 2 and Wentworth Classic Fan Flue gas fires must be installed on an outside wall. The maximum distance from the rear face of the fire mounting frame to the outside face of the wall is 600mm. The minimum is 300mm. The effective wall thickness can be increased by the addition of an internal fire surround. 2. The flue terminal must be located in a suitable position on an outside wall taking into consideration the dimensions shown in Fig. 3. 3.
3.0 Site Requirements - Page 8 3.5 Clearances (Fig. 7) 1. Shelf Clearance - minimum clearance from the hearth to the underside of a combustible shelf should be 830mm (3221/32 in) provided the shelf depth is 150mm (529/32 in) or less. When the shelf depth is increased by increments of 12.5mm (15/32 in) greater than 150mm (529/32 in), add 25mm (1in) to the 830mm (3221/32 in). 2.
4.0 Electrical - Page 9 4.1 Electrical Supply & Connection 1. All extemal wiring to the appliance must be in accordance with the latest I.E.E. Wiring Regulations and any local regulations that apply. 2. Ensure that any cables are not pulled tight and that it is possible to isolate the electrical supply to the fire for servicing. 3. In the event of an electrical fault after installation of the appliance, preliminary electrical system checks must be carried out i.e.

5.0 Installation - Page 11 5.1 Initial Preparation 1. Unpack the appliance from the carton and check all items are present. The ceramic coal bed items should be left in their box until required. 2. Some sheet metal parts may be fitted with protective plastic coating which must be removed prior to installation. 5.2 General Preparation 1. Make sure the chosen position will comply with the installation requirements detailed in section 3.0 Site Requirements. 2.
5.0 Installation - Page 12 5.3 Preparation of the Site (cont) 4. Measure 400mm up from hearth level and mark this dimension on the wall. Drill through the inner and outer walls at the mark using a suitable pilot drill at a point corresponding to the centre line of the fire flue outlet (Fig. 14). 5. From outside consider the position of the pilot hole in relation to the brickwork. The fan box is 3 bricks high and requires a cut-out in the wall 95mm above and 120mm below the pilot hole.
5.0 Installation - Page 13 5.4 Preparation of the Site - Fire fitted Into a recess 1. A suitable liner should be made to enclose the fire (Fig. 16). This should be fitted within the false fire surround. It should be 24mm thick and be of Supalux or similar noncombustible board. If 24mm material is not available two or more smaller boards may be used. It should extend from the front of the fire mounting face to the inside face of the outside wall.
5.0 Installation - Page 14 5.4 Preparation of the Site - Timber Frame Dwelling 9. This installation requires a 150mm diameter piece of single wall flue pipe or similar for use as a metal sleeve (Fig. 19). 10. This installation details the use of a fire surround or false chimney breast, having a minimum depth of 140mm, which allows the fire to be positioned in front of the wall with a hole in the inner wall for the flue only. The maximum surround depth will depend upon the wall thickness.
5.0 Installation - Page 15 5.4 Preparation of the Site (cont) 16. Taking into consideration the dimensions in fig.13 and 14 on page 12 and the position of the pilot hole, cut a suitable hole for the flue box assmebly. 17. Once the height of the flue has been determined make a hole through the wall to accept a 150mm diameter sleeve. Ensure that when the 150mm diameter hole is cut through the wall and the rectangular recess is cut in the outer wall, no timbers are cut. 18.
5.0 Installation - Page 16 5.5 Fitting the Fan Box 1. Place the power supply cable and fan to fire harness in their intended positions, passing through the hole in the wall where applicable. 2. Either fit the liner into the recess and pass the fan to fire harness through the hole in the liner, or complete the false chimney breast or surround incorporating the liner as appropriate. 3. Unpack the fan box assembly and undo the screws retaining the brown fan box cover.
5.0 Installation - Page 17 5.5 Fitting the Fan Box (cont) 14. Locate the fan box and flue assembly in the flue box collar and secure with the screws previously removed and refit the pressure switch bracket (Fig. 23). Reconnect the sensing tube (Fig. 24). 15. Fit the fan box cover to the fan box assembly. A TERMINAL GUARD IS RECOMMENDED Baxi Heating Part No 245770. Position the guard over the fan box. Ensure the guard is equally spaced about the fan box.
5.0 Installation - Page 18 5.6 Fitting the Fire 1. There are 2 methods of fixing the fire in position, using the eyebolts and cables or simply screwing through the outer fire frame with 4 screws to the wall or surround face. NOTE: It is recommended that the appliance is screwed to the wall or surround face. The eyebolt and cable method can only be used when the appliance is installed in a false chimney breast or surround. 2. Either mark the wall as shown (Fig.
5.0 Installation - Page 19 5.6 Fitting the Fire (cont) SCREW FIXING METHOD 1. Fit the fan box harness lead through the hole at the right hand side of the fire.
