10.4 Assembly
of
Boiler
Installers must ensure compatibility between boiler
body and burner by referring to Figures 11.1, 11.2 &
11.3. If in any doubt, contact Hamworthy Heating for
assistance.
Further to assembly of the sections, proceed as fol-
lows (refer to Fig. 15.1):
a.
Locate and fit the flue collector box (23) to the
upper part of the rear casting using the studs, nuts
and gaskets (22) provided. The rear access doors
(25,26) will need to be loosened to allow correct
fitting of gaskets.
b.
Locate and fit the burner mounting plate (13)
ensuring that the pads of insulation are packed into
the burner aperture and that the fibre board gasket
(12) is in position. Carefully cut a hole through both
the fibre pads and board, large enough to accept the
burner blast tube.
c.
Locate the foil covered insulation wrap which
comprises a front blanket, a rear blanket and
lengths of straight wrap. Position the front and rear
blankets on the boiler so that the cut outs align with
the appropriate items, i.e. burner mounting plate,
thermostat pocket, flue collector and return connec-
tion. Mould the excess wrap backwards around the
edges of the boiler sections and tape to secure.
Position the straight wraps over the boiler body.
Where more than one wrap is used, they should be
overlapped so that the front and rear edges fall flush
with the front and rear of the boiler. Secure wraps in
position by using tape or strapping and buckles.
For further details, see instruction sheet packed with
insulation.
Note!
The front and rear insulation pieces will need
to be removed for maintenance of the boiler.
d.
Using a combination of M10 x 35 hex head
bolts, nuts & washers and existing tie rods fit 4 off
casing support brackets as shown below.
e.
Locate burner onto mounting plate through
lower front casing panel.
f.
Complete all pipework connections and fuel
lines.
g.
Complete installation by fitting casing and
control panel - refer to Section 10.5 and 10.6.
