Mounting the boiler
1 Take the protective caps off the boiler pipe-
work.
2 Thoroughly clean the connections.
3 Mount the boiler on its bracket.
4 Fix the c.h. valves A and gas cock B (¾”) to the
boiler using the ¾” gaskets (Fig. 6.3)
5 Fix the ø 22 mm pipes C (c.h. circuit) to the c.h.
valves A and the ø 22 mm pipe D (gas) to the
cock B using the ¾” gaskets.
6 Repeat the above procedure for the d.c.w. inlet
utilising the ½” cold water inlet valve E, the ø 15
