11.1 Fitting the coaxial

11.1 Fitting the coaxial flue (Ø 60/100 Horizontal) CONTENTS: 1X SILICONE O-RING (60mm) 1X ELBOW (90 O ) 2X WALL SEALS (INTERNAL &EXTERNAL) 1X FLUE PIPE INCLUDING TERMINAL (1 METRE - 60/100) 1X FLUE CLAMP 1X SCREWS 1x Seal Once the boiler has been positioned on the wall, insert the elbow into the socket and rotate to the required position. NOTE: It is possible to rotate the elbow 360 o on its vertical axis. Using the flue clamp, seals and screws supplied (Fig 11.5) secure the elbow to the boiler. The 1 metre horizontal flue kit (3318073) supplied is suitable for an exact X dimension of 815mm. Measure the distance from the face of the external wall to the face of the flue elbow (X - Fig 11.4), this figure must now be subtracted from 815mm, 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 11.5). e.g. X = 555mm 815-555 = 260mm (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 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 outside of the building, the grey outer seal being fitted last. Clamp Seal Screws Fig. 11.5 24

11.2 Fitting the Coaxial Flue (Ø 60 / 100 Vertical) NOTE: SEE PAGE 28 FOR MAXIMUM AND MINIMUM FLUE RUNS. CONTENTS: 1X SILICONE O-RING (60 mm) 1X CONICAL ADAPTOR (60/100 mm) 1X VERTICAL FLUE KIT (80/125 mm) 3X SCREWS The vertical flue kit is supplied with a specially designed weather proof terminal fitted, it can be used either with a flat roof or a pitched roof. The Vertical flue kits useable lengths with the pitched roof flashings are indicated in Fig. 11.6. Before proceeding to fit the flue, ensure that the maximum flue length has not been exceeded (See the tables on Page 20) and that all elbows and bends have been taken into consideration, the maximum flue length is 4 metres, for each additional 90 o elbow 1 metre must be subtracted from the total flue length, and for each 45 o 0.5 metres must be subtracted from the total flue length (the height of the vertical adaptor and a 45 o bend can be seen in Fig. 11.7). Mark the position of the flue hole in the ceiling and/or roof (see Fig. 11.6 for distance from wall to the centre of the flue). Cut a 120 mm diameter hole through the ceiling and/or roof and fit the flashing plate to the roof. DO NOT cut the vertical flue kit. To connect the vertical flue kit directly to the boiler, place the vertical starter kit (Part No. 3318079) (see Figs. 11.6 & 11.7) onto the exhaust manifold and secure with the clamp, fit the vertical adaptor onto the vertical starter kit (note: there is no need to use a clamp to secure this as it is a push fit connection), the vertical flue kit must then be inserted through the roof flashing, this will ensure that the correct clearance above the roof is provided as the terminal is a fixed height. Should extensions be required, they are available in 1 metre (Part No. 3318077), 500 mm (Part No. 3318078) and 160 mm lengths, they must be connected directly to the vertical starter kit before connecting the adaptor to allow the vertical flue kit to be fitted. In the event that extension pieces need to be shortened, they must only be cut at the male end and it must be ensured that the inner and outer flue remain flush. When utilising the vertical flue system, action must be taken to ensure that the flue is supported adequately to prevent the weight being transferred to the appliance flue connection by using 1 flue bracket per extension. When the flue passes through a ceiling or wooden floor, there must be an air gap of 25 mm between any part of the flue system and any combustible material. The use of a ceiling plate will facilitate this. Also when the flue passes from one room to another a fire stop must be fitted to prevent the passage of smoke or fire, irrespective of the structural material through which the flue passes. 153 Fig. 11.6 Fig. 11.7 25
