  • Page 4: Part 1: Appliance Data

    PART 1: APPLIANCE DATA This product uses fuel effect pieces, burner back wall and gaskets containing Refractory Ceramic Fibres (RCF), which are man-made vitreous silicate fibres. Excessive exposure to these materials may cause temporary irritation to eyes, skin and respiratory tract. Consequently, it makes sense to take care when handling these articles to ensure that the release of dust is kept to a minimum.

  • Page 5: Part2: General Installation Requirements

    PART2: GENERAL INSTALLATION REQUIREMENTS The installation must be in accordance with these instructions. For the user’s protection, in the United Kingdom it is the law that all gas appliances are installed by competent persons in accordance with the current edition of the Gas Safety (Installation and Use) Regulations.
  • Page 6 materials must be removed from the area covered by the metal outer surround of the appliance. We suggest that the actual surround is used as a template to mark the area for combustible cladding removal. The appliance can be fitted to a purpose made proprietary class “O” 150°C surround. The opening in the surround or wall recess for the fire box must be within the limits shown in figure 1.
  • Page 7 The flue terminal should be located so that the wind can blow freely across it at all times and where any blockage due to leaves, snow, etc. is unlikely. The minimum allowable distances from the terminal are shown in figure 2 and the table. Note: The distances are from the edge of the vertical exit slots in the terminal not from the edges of the rectangular box (See figure 2).

    PART 4: PREPARING FOR INSTALLATION Check ignition spark Before attempting to install, it is worth checking that the piezo electric spark ignition system operates satisfactorily. To initiate the spark, depress the control knob and while keeping it depressed, turn anticlockwise through approximately 60° to the “PILOT/IGN” position. A spark should track from the electrode pin to the thermocouple tip.

  • Page 11: Brick, Stone Etc. Building. Main Case Recessed Into Wall

    Brick, Stone Etc. Building. Main Case Recessed Into Wall (Figure 8) This installation has the fire box recessed into the inner wall of the building. The front flanges of the fire box and the appliance metal decorative surround will abut the front surface of the wall. The non-combustible hearth must project at least 345mm in front of the convection box front flanges and be at least 625mm wide (Figure 1).

  • Page 12: Wall Preparation For Flue Tube

    Wall preparation for flue tube. The flue must be installed so that it is at right angles to the back panel of the fire all round the flue circumference. The fire itself should be fitted vertically against a flat wall. Where this is difficult to achieve due to building inaccuracies care should be taken to ensure that the back of the fire is not stressed in any way due to distortion of the assembly when tightening the fixing screws.

  • Page 13: Fixing The Appliance In Position

    The area immediately behind the firebox must be separated from the combustible elements of the inner wall by 25mm thickness of non combustible material. This can consist of the usual 13mm plasterboard wall lining plus 12mm of “Superlux” or similar non-combustible material - see figure 12. Fixing the appliance in position There are two methods of fixing that may be used: 1.
