SITE R R EQUIREMENTS ( ( continued) This appliance requires a natural draught flue system which may be one of the following; 225mm x 225mm (9in x 9in) brick or stone. 175mm (7in) minimum diameter lined brick or stone. 175mm (7in) minimum diameter twin wall flue conforming to BS 715. Any existing under grate draught device must be sealed off.
VENTILATION No purpose provided ventilation is normally required for this appliance. The requirements of other appliances operating in the same room or space must be taken into consideration when assessing ventilation. If spillage is detected when commissioning the appliance then amongst other problems there may be insufficient natural ventilation for the correct operation of the flue.
UNPACKING T T HE A A PPLIANCE Stand the carton right way up, cut the strapping bands and remove the top end cap. Read all the instructions before continuing to unpack or install this appliance. Remove the box containing the fire front, and the bags and boxes containing the ceramic parts. Remove the card- board packing pieces, and any bags containing other fittings or parts.
PREPARING T T HE O O PENING Before installing the fire, check the flue using a smoke pellet. All of the smoke should travel up the flue and exit correctly from the terminal. If problems are found, DO NOT fit the fire until corrective action is completed. Protect the decorative hearth whilst pushing the firebox in and out of the opening.
10.0 GAS S S UPPLY R R OUTING ( ( continued) The gas pipe must be suitably protected where it passes through fireplace openings. An isolator cock or restric- tor elbow must be fitted to the incoming supply to facilitate servicing. Any sleeving should be sealed to the pipe at its ends.
11.2 GAS CONNECTION Refit the burner tray into the firebox, fit the two screws through the locating holes in the tray legs, and tighten. Purge the gas supply thoroughly to remove air and dirt/debris BEFORE connection. Now disconnect the inlet restrictor elbow from the inlet pipe.
14.2 SPARK FAILURE The gap between the spark electrode and the pilot should be 3.5 - 4.5mm to produce a good spark. There should be no need to adjust this. If under any circumstances the electric spark fails, the pilot may be lit manually by pro- ceeding with the ignition sequence as previously described, and after turning the control knob through the spark position, the knob should be held in and the pilot lit with a taper.
14.5 TESTING FOR SPILLAGE ( ( continued) A.25mm down Fireplace Opening Cross section of smoke match tube from opening 25mm from front of opening. Tube Disregard Crimp Match outer 50mm Make a smoke match tube from 10mm either side of diameter tube.
