INSTALLATION BEFORE THE

INSTALLATION BEFORE THE DEVICE IS USED, FOR THE FIRST TIME THE TRAP MUST BE FILLED WITH WATER. The siphon is filled with water during deaeration procedure of the boiler (or heating system) - see p. 32 Ensure that the siphon contains water; if not, it must be refilled. Open the manual air vent (2) on the main exchanger until complete filling. Check again the system pressure on the pressure gauge. Water circuit diagram 1 3 4 5 6 21 WARNING!

INSTALLATION Connecting the Flue Flue System The provision for satisfactory flue termination must be made as described in BS 5440-1. The appliance must be installed so that the flue terminal is exposed to outdoor air. The terminal must not discharge into another room or space such as an outhouse or lean-to. It is important that the position of the terminal allows a free passage of air across it at all times. The terminal should be located with due regard for the damage or discolouration that might occur on buildings in the vicinity, it must also be located in a place not likely to cause nuisance. In cold or humid weather water vapour may condense on leaving the flue terminal. The effect of such “steaming” must be considered. If the terminal is less than 2 metres above a balcony, above ground or above a flat roof to which people have access, then a suitable stainless steel terminal guard must be fitted. The minimum acceptable spacing from the terminal to obstructions and ventilation openings are specified in Fig. 1.
