[. . . ] It is important to put the centering spacer, supplied with the unit, inside between the two pipes, from the side opposite the extension's straight end. NOTE: a suitable support bracket is available from Ravenheat Manufacturing and should be used to support flue length at least every 1. 8 metre preferably at each joint this bracket should be secured to wall and flue duct. - Measure the distance Y between the centre of flue duct hole to the corner. out from the wall in order to enable the boiler to be located. Fig. 38 5. 5. 11 INLINE FLUE BEND Measure the distance between the flue bends or the flue/terminal assembly. The measurement should be taken from the outer edge of the flue and bend (Fig. COMPLETING BOILER INSTALLATION Reassemble the outer casing (sect 5. 4) proceeding in this order 1) Fit the two sides. 38-39) -Attach the template to the wall with adhesive tape, making sure that the centre line is vertical and that the distance from the centre line to the nearest side wall is not less than 305 mm. -Mark the four boiler securing holes on the wall and extend the axis of the flue duct hole to the side wall ensuring it is horizontal. 398 KEY 56 - Sample point (if required) 57 - Elbow Header 59 - Rubber seal 0 60 63 -Air intake duct extension 64 - Flue Exhaust duct extension 65 - Pipe centering spring 128 - In Line Bend (45" and/or 90") USING AN INLINE 135o OR 90o BEND & VERTICAL FLUE SECTION Deducted from overall length for each 90" bend 750 mm 135" bend 375 mm VERTICAL FLUE OPTIONS The vertical flue kit is intended for use where a horizontal flue outlet is not possible or desired. The vertical flue can be used either with a flat roof or a pitched roof (maximum pitch 60"). Where a straight vertical flue is not possible or desired, an offset vertical flue can be used in conjunction with a side horizontal flue extension piece and an inline 90" flue bend. 5. 7. 2 Detach the straight header and replace it with the elbow header (supplied on request), positioning the elbow towards the required direction (Fig. duct is inserted into the fan and that the rubber seal and orifice are been correctly fitted. - If the standard, duct furnished with the boiler is too long (position of the boiler from the wall to go through as illustrated in the drawing and wall thicknesses less than what was specified above) it can be shortened as follows: (Fig. 31-32). turn the flue terminal clockwise and push to disengage inner flue duct. - Reassemble the two tubes turn the flue terminal anti clockwise to lock together. Insert the flue assembly into the wall, making sure it will not interfere with the boiler body (Fig. Working above the boiler pull the flue duct towards the elbow in order to engage tube 61 into its header 57A. Extension kits are available on order for flue extension of up to 3. 5 metres total length (Fig. 5. 6. 1) Fitting valves pack Remove plastic caps from boiler connection and fit flanged copper tail and valves as per Fig. 46 using washers provided.

Fit gas service cock to the boiler via the union nut and connect gas pipe. [. . . ] However, if it is necessary to replace the central heating expansion vessel the boiler must be removed from the wall as follows. Close the on/off valve on the domestic cold water, central heating and gas supply. Drain domestic water from the lowest hot water tap and drain point on DHW inlet cock (Fig. Disconnect mains cables and any other connections (room thermostat, programming clock). [. . . ]
