1. GENERAL INFORMATION The Britony SX Water Heater is a room sealed, fanned flue, mulitpoint water heater. The appliance has been designed for domestic use only and to be connected to a mains cold water supply with a minimum pressure of 0.5 bar. A permanent electrical connection is required and should be provided by use of a fused spur. The electrical supply should be via a double pole isolating switch with 3mm contact separation in both poles.
2.2 Initial Set-Up IMPORTANT: The installing technician should explain to the user how the water heater works, the safety devices it includes and how to use it. Before turning the water heater on, it should be connected to the electrical mains via a double pole isolating switch with 3mm contact separation in both poles. • Make sure that gas is supplied to the water heater (valve on gas pipe open) and purge any air as necessary • Make sure that the electrical supply is turned on. 2.
IMPORTANT: In the event that there is a risk of the appliance freezing, close the cold water inlet valve and drain the water heater by opening a hot water tap, see Section 2.5 Useful Information. 2.4 Maintenance Note: Before carrying out any maintenance or repair work on the appliance, the water heater MUST be disconnected from the electrical mains and the gas and water isolating valves MUST be closed. CHAFFOTEAUX & MAURY recommends that the water heater be serviced by authorised personnel once a year.
3 INSTALLATION INSTRUCTIONS 3.1 Description of the Appliance SX water heaters are sealed electronic water heaters, with electronic ignition and ionisation safety devices, they have a modulating burner and are connected to the mains water supply; they provide domestic hot water. Their self-contained combustion chambers with fans for the intake of external air and the extraction of combustion products, allow them to operate totally independently from the room in which they are installed.

3.7 Reference Standards In the United Kingdom, the installation and initial start up of the water heater must be by a CORGI Registered installer in accordance with the installation standards curently in effect, as well as with any and all local health and safety standards i.e. CORGI. Q Q I Q D,E F In the Republic of Ireland the installation and initial start up of the appliance must be carried out by a Competent Person in accordance with the current edition of I.S.
3.8 Installing the Water Heater The appliance must be provided with a means of isolation. If installed in a bathroom, the means of isolation must be external to the bathroom or a double pole cord switch fitted.
3.8 Installing the Water Heater Purging the Gas Supply Once all the above checks are complete, it will be necessary to purge the gas supply of air. Do not under any circumstances attempt to purge the gas pipe of air by continually pressing the On/Off button to reset. If it is necessary to do this, you must wait at least three minutes between each press of the On/Off button. Completion Once installation is complete, commission the appliance as instucted in Section 5, page 19).
4. FITTING THE FLUE The water heater must only be installed with a flue supplied by the manufacturer. These kits are supplied separately to the appliance in order to respond to different installation solutions. For more information with regard to the inlet/outlet accessories consult the flue brochure and the following instructions. The water heater is supplied ready for connection to a concentric gas intake and exhaust duct system.
4.1 Fitting the Coaxial Flue (Ø 60/100 Horizontal) Continued/...... Clamp e.g. X = 508mm - 48mm = 460mm 823 - 460 = 363mm (Length to be cut from the plain end of the flue). Ensure that the inner flue is 23mm longer than the outer flue. See Fig. 14. Once cut to the required length, ensure that the flue is free from burrs and reassemble the flue.
4.2 Fitting the Coaxial Flue (Ø 60/100 Vertical) Continued/...... DO NOT cut the vertical flue kit. To connect the vertical flue kit directly to the boiler, place the vertical starter kit (Part No. 3318008) (see Fig.
4.3 Fitting the Coaxial Flue (Ø 60/100 Vertical) Continued/....... FIG. 18 FIG. 19 4.4 Fitting the Twin Pipe (Ø 80/80) NOTE: SEE PAGE 18 FOR MAXIMUM AND MINIMUM FLUE RUNS. Where it is not possible to terminate the flue within the distance permitted for coaxial flues, the twin flue pipe can be used by fitting a special adaptor to the flue connector and using the aperture for the air intake located on top of the combustion chamber.
4.4 Fitting the Twin Pipe (Ø 80/80) Continued/....... 122 200 230 MIN * 132 123,5 When siting the twin flue pipe, the air intake and exhaust terminals must terminate on the same wall, the centres of the terminals must be a minimum of 280 mm apart and the air intake must not be sited above the exhaust terminal (refer to Fig. 23). The air intake pipe can be run horizontally, however, the terminal and the final 1 metre of flue must be installed with a fall away from the boiler to avoid rain ingress.

5. Comissioning Once the water heater installation has been completed, it is necessary to commision the appliance as follows: Gas supply installation Inspect the entire installation including the meter, test for soundness and purge, as described in BS 6891. Checking electricity supply Carry out preliminary checks for earth continuity, polarity, resistance to earth and short circuit. Leave the appliance with the front cover fitted and the mains electrical supply isolated. Fig.
6. SERVICING INSTRUCTIONS A To ensure efficient safe operation, it is recommended that the water heater is serviced annually by a competent person. Before starting any servicing work, ensure both the gas and electrical supplies to the water heater are isolated and the water heater is cool. Before and after servicing, a combustion analysis should be made via the flue sampling point.
