means of M10 x 85mm nuts (5). See figs 7 and 9.
3. Mount each of the four horizontal casing support channels (6) (as shown in fig 1) and fasten them
each by using M8 x 20 bolts. (Note: Horizontal profiles on boilers 510-640 are made in two parts
which have to be joined using 4 screws M5 as supplied). See figs 7 and 8.
4. Apply the front (8) and rear (9) insulation panels. See fig 8.
5. Fix the front side panels (10 and 11) by sliding under bottom horizontal and lifting over top
horizontal. Fasten panels to front section by M10 x 12 (12) upper fixings and M10 x 78 (13) lower
fixings. Fix self tapping screw (14) to bottom horizontal. See fig 10.
6. Fit casing intermediate side panels (15) onto horizontal profiles. (Note: Only fitted to boilers
425-640). See fig 10.
7. Fit casing rear side panels onto horizontal profiles and fasten onto rear section by using M10 x
12 (17). Fasten bottom of casing to bottom profile using self-tapping screw. (14). See fig 10.
8. Fit lower front casing (18) and fasten by using M10 x 12 (19) supplied. See fig 10.
9. Unpack boiler control panel and remove upper shell by unscrewing 3 x retaining screws.
Carefully uncoil limit/control/thermometer capillaries and pass through grommet located
at the base of the control panel. Pass limit/control/thermometer capillaries along
with burner control cable, through cut-out in top panel. Fasten control panel to top panel by
using self-tapping screws (supplied). Replace upper shell.
10. Fit front top casing panel (20), fit limit/control/thermometer phials into instrument pockets
located on the flow pipe spool piece.
11. Fit rear top panel (21), see fig 10.
12. Route burner cables through most appropriate aperture in side casing front leading edge and
close apertures with plates provided.
13. Fit front section insulation slab (22) inside upper front casing (23). See fig 10.
14. Fit upper front casing (23) (front top panel will have to be lifted slightly to enable fitting of front
upper panel). See fig 10.
