Boiler Installation
The boiler is despatched fully assembled (except for larger
boilers which have separate casing packs) and only
requires the usual water, flue and electrical connections
to be made.
1. Connect boiler to the heating and hot water systems
at the two pairs of side tappings. Fill system and
check for leaks (maximum working head 52ft.).
2. Make flue connection to chimney with cast iron or
vitreous enamelled pipe, fitting sockets uppermost.
Check draught stabiliser for free operation of the flap.
Notes:
a.
Horizontal flue runs must not be used.
b. A maximum of two flue bends is permissible but
these must incline at an angle of 135 and be
fitted with soot cleaning covers.
c. Under no circumstances must a single-wall flue
pipe be used as an outside chimney. The chimney
must be either a conventional brick construction
with a liner or a factory made insulated chimney
conforming to BS 4543 Part 2:. Recommended
installation
practice for chimneys and flues is
given in BS 6461 Parts 1 & 2 and also shown
below.
3. Connect the electrical supply in heat resisting cable
B A S E C or H A R approved, from a switched plug
(5 amp fuse) to the mains terminal block under
thermostat cover. Pass cable along bottom of boiler
and through bush in left handside. Check operation
of forced draught fan by turning on thermostat, also
ensure that the air control flap pivots freely in fan throat.
4. Position the fuel regulator on the appropriate hole to
suit the fuel being used. (see Operating Instructions
for settings).
IMPORTANT NOTICE:
Heat-Leak Device
As with all solid fuel boilers, a certain amount of
residual heat is generated even when the appliance
is slumbering. To ensure that the boiler continues to
operate this excess heat must be dissipated. It is
essential that a heat leak radiator or towel rail is
fitted to the heating system to disperse this heat.
The heat leak device fitted must meet the following
emission values and should be located in the gravity
circuit parallel with the indirect cylinder.
TRG 45
0.75 Kw ( 2,500 Btu/h) MIN
TRG 60
0.75 Kw ( 2,500 Btu/h) MIN
TRG 80
0.75 Kw ( 2,500 Btu/h) MIN
If the appliance is replacing an existing installation, it
may be necessary for the installer to recalculate the
heat losses for the premise, as building changes
made over time (such as double glazing, cavity
insulation, more efficient hot water cylinders) can
significantly alter the heating requirements.
