Resumen del manual
Suitable types of chimney include the following. • Masonry chimney built with clay or concrete liners, or a chimney block system meeting Building Regulations. • Precast concrete gas flue block complying with BS 1289: Part 1 Factory made metal chimney complying with BS 715 (often called "Twin wall Class 2 chimney") or Factory made metal insulated chimney complying with BS 4543: Part 2 (often called "Class 1 prefabricated metal chimney"). To ensure the flue gases are kept warm an insulated chimney system should be used if the chimney is positioned outside the building. The flue must be terminated with a suitable chimney pot or cowl and the chimney or flue shall be swept prior to installation unless the chimney is clean and unobstructed. The flue and chimney installation must be carefully checked by a competent person before fitting the stove to ensure it is suitable and will work safely. The flue must also pass a Flue flow test (smoke test) to BS 5440: Part 1. For advice on flues and chimneys contact; NACE (National Association of Chimney Engineer): telephone 0800 0924019 or NACS (National Association of Chimney Sweeps): telephone 01785 811732 Becton Bunny & Becton 7 mk3 Gas stoves INSTALLATION The Becton gas stove is designed so that the flue can be fitted to either the top or the rear of the appliance. Fit the flue spigot and blanking plate for either top or rear flue outlet in accordance with figure 6a or 6b (below). Lock the blanking plate in place by rotating anti- clockwise and tighten by tapping gently with a block of wood and mallet. Fit the spigot to the unused opening in the same way. The units are sealed by the attached gaskets. Fig 6c REAR FLUE Open Hearth Fit and seal a ‘T’ section (with soot box) directly into the flue spigot. The maximum horizontal section allowed is 150mm. Provide a minimum vertical height of 600mm of flue from the height of the rear flue outlet. See figure 7b. Closure Plate #Connect the flue spigot to the rear outlet. #Connect a flue extension to the spigot. #Fit the closure plate in fireplace. #Position the fire so the flue extension passes through the hole in the closure plate. #Ensure all joints are suitably sealed. See Figure 7c. TOP FLUE Provide a minimum vertical height of 600mm of flue measured from the top of the appliance. See Figure 7d. Move the fire, with flue spigot in place, into position under the flue and seal the spigot/flue connection with fire cement. (Ref. Fig. 6c). It is recommended that a smoke test is performed inside the fire to ensure that adequate flue draw is evident. Fig 7a Becton Bunny & Becton 7 mk3 Gas stoves INSTALLATION Fig. 7b.

FIRE LOCATION The appliance must not be installed in a room or space, which contains a bath or shower. This fire is designed for use with either top or rear flue outlets and must be mounted on a hearth with a minimum of 12mm non-combustible material thickness. There must be a minimum of 200mm clearance from the sides of the fire to any combustible sidewalls. Fig7a. For clearance from the top of the fire to any combustible shelf. Fig 7b. (See Graph 1). There must be a minimum of 230mm from the rear of the fire to any combustible back wall. Fig 7b. With a Non-combustible back wall the fire can be pushed back until the top diverter touches the wall, although to improve access and air circulation a minimum distance of 100 mm is recommended. Fig 7c. Reference non-combustible side walls a minimum of 100mm is recommended. Do not place any furniture or furnishings (including curtains) within 1 metre of the fire.

If the rear of the fire is to be pushed up against a surface it must be of a non-combustible material. The hearth must protrude at least 25mm in front of the glass window and 150mm either side. The hearth must not be capable of inadvertent covering by a carpet or rug. This should be achieved by either: The hearth being 50mm above the level of the room floor. A 50mm high fender or kerb being fixed around the edge of the hearth. CONNECTING THE GAS SUPPLY Once the fire is in place it is then possible to connect the gas supply.
