INSTALLATION Connecting

INSTALLATION Connecting the Flue Flue System The provision for satisfactory flue termination must be made as described in BS 5440-1. The appliance must be installed so that the flue terminal is exposed to outdoor air. The terminal must not discharge into another room or space such as an outhouse or lean-to. It is important that the position of the terminal allows a free passage of air across it at all times. The terminal should be located with due regard for the damage or discolouration that might occur on buildings in the vicinity, it must also be located in a place not likely to cause nuisance. In cold or humid weather water vapour may condense on leaving the flue terminal. The effect of such “steaming” must be considered. If the terminal is less than 2 metres above a balcony, above ground or above a flat roof to which people have access, then a suitable stainless steel terminal guard must be fitted. The minimum acceptable spacing from the terminal to obstructions and ventilation openings are specified in Fig. 1.

INSTALLATION Warning The exhaust gas ducts must not be in contact with or close to inflammable material and must not pass through building structures or walls made of inflammable material. When replacing an old appliance, the flue system must be changed. Important Ensure that the flue is not blocked. Ensure that the flue is supported and assembled in accordance with these instructions. Installation without extension Level 118 150 mm Installation with extension slope * pente Level 150 mm * Min slope: 1˚ 1˚= 17.5mm per metre Fig. 3 Fitting the Coaxial Flue (Ø 60 / 100 Horizontal) Contents: 1x Silicone O-Ring (60mm) 1x Elbow (90°) 2x Wall Seals (Internal & External) 1x Flue Pipe including Terminal (1 metre - 60/100) 2x Flue Clamps 4x Screws 2x Seals Once the boiler has been positioned on the wall, fit the rubber flue seal into the internal flue turret (see diagram opposite), Insert the elbow into the socket and rotate to the required position. note: It is possible to rotate the elbow 360° on its vertical axis. Using the flue clamp, seals and screws supplied (Fig 4) secure the elbow to the boiler. The 1 metre horizontal flue kit (3318073) supplied is suitable for an exact X dimension of 753mm. Measure the distance from the face of the external wall to the face of the flue elbow (X - Fig 2), this figure must now be subtracted from 753mm, you now have the total amount to be cut from the plain end of the flue. Note: A Plume management kit is available for 60/100 horizontal termination. Instructions for installation are supplied with the Plume management kit. Draw a circle around the outer flue and cut the flue to the required length taking care not to cut the inner flue, next cut the inner flue ensuring that the length between the inner and outer flue is maintained. (Fig 4). e.g. X = 555mm 753-555 = 198mm (Length to be cut from the plain end of the flue). Once cut to the required length, ensure that the flue is free from burrs and reassemble the flue. If fitting the flue from inside of the building attach the outer wall seal to the flue terminal and push the flue through the hole, once the wall seal has passed through the hole, pull the flue back until the seal is flush with the wall. Alternatively, the flue can be installed from outside of the building, the outer seal being fitted last. Should the flue require extending, the flue connections are push fit, however, one flue bracket should be used to secure each metre of flue. Note: See table for maximum and minimum flue runs. / 19
