installation Warning The

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 Fig. 3 Installation with extension * slope pente Level 150 mm * pente slope 55 mm mm par per mètre metre 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 811mm. 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 811mm, you now have the total amount to be cut from the plain end of the flue. 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 811-555 = 256mm (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 the inside of the building attach the grey 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 the outside of the building, the grey 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. During use it is possible small quantities of condensate will drip from the end of the terminal. Pay attention when siting the flue termination point. Applies to all horizontal terminations. 22

installation Clamp Seal Screws Fig. 4 Fitting the 5” Flue (Ø 80 / 125 Horizontal/vertical) Total length of vertical kit 1240 mm 180 mm Useable length of vertical flue 575 mm* Fig. 5 Once the boiler has been positioned on the wall, it is necessary to insert the Ø80/125 adaptor (Fig. 5) for both horizontal and vertical flue runs into the boiler flue socket (not supplied with flue kit - Part No 3318095). Push the adaptor onto the boiler’s flue connection, grease the seals then add extensions or elbows as required, secure the adaptor, using the clamp and screws provided. To fit extensions or elbows it is first necessary to ensure that the lip seal is fitted correctly into the inner flue, once verified, it is simply necessary to push them together, no clamps are necessary to secure the flue components. Before proceeding to fit the flue, ensure that the maximum flue length has not been exceeded (See the tables) and that all elbows and bends have been taken into consideration, the maximum flue length is 10 metres, for each additional 90° elbow 1 metre must be subtracted from the total flue length, and for each 45° bend 0.5 metres must be subtracted from the total flue length (the height of the vertical adaptor and a 45° bend can be seen in Fig.6 and a 90° bend in Fig. 7). Note: DO NOT cut the vertical flue kit. Fig. 6 Fig. 7 23
