[. . . ] COMBINATION BOILER installation (leave these instructions instructions with the User or at the Gas Service meter) Looking Good. Heating Better The CELTIC 2. 20 FF is a wall mounted, low water content fanned balanced flue appliance suitable for central heating and instantaneous hot water. The boiler is designed for sealed systems oniy and included in the appliance are the expansion vessel, circulating pump, temperature and pressure gauges, safety valve and electrical connection box. The flue which is 100 mm (4 ins) round pipe can be directed to the rear or to the left or right and can be extended to a maximum length of 3 m thus facilitating installation remote from an external wall. [. . . ] Terminal COM (P) and NO (21 - the common and normally open contacts. Before plastic cover is fiied does not foul turet fixing screw. ensure cable route Making the electrical connection See sect. 2 for the electrical supply requirements. c) Open door on left hand side of electrical box. d) Cut the cable entries to the size of the cable being used which should not be less than 0. 75 m* and must be heat resisting e) Remove cable clamp f) Connect permanent live and neutral supply to terminal Ph & N. h) Connect external controls - time clock room stat etC across terminals 6 & 7. k) Close door and secure with two screws. The length of the earth wire between the cable clamp and the terminal must be such that the live and neutral wires become taut before the earth wire if the supply cord is pulled. In the event of an electrical fault after installation preliminary electrical system checks must be carried out. Checks to ensure electrical safety should be carried out by a competant person ie. earth continuity, polarity and resistance to earth. Use only voltage free external control switching. No supply voltage should be connected to terminals 6 or 7. 13 5.
