[. . . ] - TELEPHONE (0113) 252 7007 ELECTRONIC IGNITION - AUTOMATIC MODULATING BOILER. FOR CENTRAL HEATING AND DOMESTIC HOT WATER This new high efficient turbo-modulating boiler is designed to meet domestic hot water and central heating requirements at super high efficiency, unheard of only a few years ago. POSITION The appliance is extremely versatile as it can be fitted in almost any room. The appliance is room sealed, there is no contact between combustion chamber and living accomodation. [. . . ] Extension kits are available on order for flue extension of up to 3. 5 metres total length (Fig. 37 5. 5. 10 Each extension length extends the pipe by approximately 1000 mm long up to a maximum of three extensions. Pipeline length can be established using the instructions in section 5. 5 for rear flue outlets and section 5. 7 for side flue outlets. Extensions must be installed with the widened end of the air intake pipe and the tapered end of the flue pipe aimed towards the exhaust terminal. Extensions must be joined together, with the standard terminal pipe, inserted in each other as far as they can go. If an extension must be shortened, this must be done from the straight end, and not from the tapered end. To measure the pipeline properly all components must be assembled and total length measured before cutting. All joints must be sealed with a rubber collar, fastened with the pipe straps supplied. 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. - Connect the central heating flow pipe to the isolating cock marked CHF. - Pipe dimension's and position are marked on template supplied and Fig. 46) The domestic hot water circuit does not need a safety valve but it is essential to ensure that the pressure of the cold water supply does not exceed 10 bar. The minimum pressure needed to operate the domestic hot water system is 0. 5 bar Fig. The regulator screw on the cold water outlet of the diverter valve may be adjusted to prevent excess volume flow (Fig. Flush out all foreign matter from the supply pipe before connecting to the appliance. 46 5. 13 5. 13. 1 ELECTRICAL CONNECTIONS IMPORTANT: Electricity supply must be as specified in clause (sect. - When controls external to the appliance are required, design of the external electrical circuits should be undertaken by a competent person. Factory fitted internal wiring must not be disturbed when wiring external controls. - To gain access to the electrical box remove the front panel of the case as described in clauses (sect. - The terminals are easily visible on the front of the electronic control board (Fig. [. . . ] 93) and drain hot water from the lowest hot water tap and drain point on DHW inlet cock (Fig. 82 7. 27. 2 7. 27. 3 7. 27. 4 7. 27. 5 37 7. 27. 6 Replace in reverse order. 7. 20 Fig. 62 TO REMOVE/REPLACE THE CENTRAL HEATING EXPANSION VESSEL In the unlikely event of failure of the central heating expansion vessel it is recommended a suitable expansion vessel be fitted external to the boiler. It should be positioned on the return pipe and as close to the boiler as possible (Fig. [. . . ]
