UNPACKING THE BOILER
The standard appliance is supplied in two cardboard carton.
In addition up to two extension duct kits may be used. If the
appliance is to be installed without access to the outside wall,
the wall liner will also be required. Unpack each carton and
check the contents against the following lists:
Appliance package:
– Boiler (app mounting frame)
– Installation, servicing and User instructions
– Wall template
– Fixing screws with wall plugs and washers
Flue package:
– Telescopic flue/terminal assembly
– Flue package [1 x gasket, 2 x ‘O’ rings, 4 screws]
– Flue elbow
– Inner and outer wall seal
– Junction protective metal collar

PREPARING THE WALL
Before installing the appliance ensure that the chosen loca-
tion is suitable [section 2.2] and the requirements for flue
position [section 2.3], and minimum clearances, [Table 2 ] are
satisfied. These minimum clearances are essential to provide
access for servicing. Fix the template to the wall in the chosen
position. Mark the position of the two upper fixing holes, the
two lower fixing holes and the flue air duct hole on the appro-
priate wall. For side flue options it will be necessary to project
a horizontal centre line along the rear wall to the side wall.
Drill the top two fixing holes using a 8 mm masonry drill. Fit
the plastic plugs provided. Cut the hole in the wall for the flue
air duct. The diameter should not be less than 100 mm [4 in]
and must be horizontal. If the hole is not accessible from the
outside of the building, its minimum diameter should be suffi-
cient to allow the insertion of the wall liner 129 mm diameter,
which should be sealed with mortar. The wall liner is available
as an optional extra. Drill the lower two fixing holes using a 8
mm masonry drill. Fit the plastic plugs provided.
3.3
HANGING THE BOILER
Remove the outer case securing screws, located at the
bottom rear of the boiler, and lift the case off the
appliance. Remove the mounting bracket unscrewing the
two screws and separate the sealed chamber from the boiler
frame. Fix the frame to the wall through the screws supplied
and replace the sealed chamber and casing in position.
3.4
FLUE AND TERMINAL PREPARATION
If the wall thickness is less than 0.5 m [19 in] the flue/air duct
may be fitted without access to the outside wall providing the
optional wall liner kit is used.
[This consists of a steel pipe, 0.5 m long and 129 mm outsi-
de diameter with a 1 mm wall thickness].
3.4.1
Cutting & Setting To The Correct Length
Determine whether an extension duct (code 8084804) is
required with reference to the Table 8.
– If any extensions are required the flue and air ducts should
be joined before proceeding to the next section. The exten-
sion ducts should be joined to each other and to the standard
ducts using the following procedure (fig. 7);
– For the flue ducts in turn, push the plain end of the stan-
dard and (if using two or three extensions) extension duct
into the swaged end of the extension duct(s).
– Push an air duct in to the clamp. Join the air ducts (larger
ducts) and tighten the screws an the clamp to connect them.
– Insert the inner flue ducts and ensure the ‘O’ ring seals
are correctly located.
– If the correct length cannot be achieved with the telesco-
pic action of the flue, the end of the extension duct [air and
flue] should be cut shorter. The telescopic action of the flue
can then be used to achieve the overall correct length.
