Installation
Utilise the paper template supplied with the boiler
to determine the fixing position for the bracket and
boiler. Securely mount the bracket to the wall
using appropriate fixings suitable for the type of
wall construction and capable of supporting the
total (wet) load. Refer to the weight given in the
technical data tables specific for each model.

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
mm copper tail F with its connection nut and
two ½" gaskets.
7 Fix the ø 15 mm copper tail G with the ½" con-
nection nut and a ½" gasket.
8 Connect the pipe H (Fig. 6.4) from the pres-
