When locating the boiler, care should be taken in respect
of the flue terminal which should be within the parameters
laid down within Fig 3
Due care and attention is required when siting the boiler
not only during installation but for subsequent servicing.
The black outside casing of the boiler shall not be less
than 1 metre form the ground. A sensible maximum
height for installation is 2.5 metre from the terminal.
Boilers installed above this height must have provision
made for the health and safety of the service engineer.
Modern boilers are designed to operate at low noise levels.
However, when positioning your boiler it is not
recommended to have the terminal facing a neighbour’s
property or patio etc. It should be positioned to avoid
products of combustion entering the building. See fig. 3
a) With the template provided, mark out the proposed
hole in the chosen wall. The dimensions allow for a
tolerance of 5mm all round. It is recommended that
a cutting disc is used to remove surplus brick and
blockwork; this will ensure a uniformed aperture
opening. Care should also be taken to ensure that
the prepared aperture is parallel.
b) Insert inner wall duct together with internal mounting
plate through aperture in wall, hold centre and mark
fixing points (8) through holes in boiler mounting
plate, drill (DIA12 x 50 DEEP) and plug using screws
supplied. Affix assembly to wall, leaving screw loose
to allow fitment of external duct.
c) Insert external duct over internal duct, holes to bottom.
Adjust from wall thickness ensuring a minimum of
40mm from wall face to front of sleeve; this is to
allow for the fitment of oil line bulkhead fittings,
valves and combustion air valves. On completion,
secure all screws. Slide trim over sleeve, mark and
drill holes. 3-holes 12 Dia x 50mm deep
deep. Before fixing trim to wall, ensure wall is made
good and finally secure trim to wall. Silicone should
also be applied to area. See Fig. 2
CAUTION:
The heat exchanger weighs 49kg max, and requires
two people to lift into position.
When fitted, the heat exchanger is secured in place
by 3 x M8 flange nuts.
Water Connection
The boiler has two 22mm compression connections iden-
tified on wall frame (supplied with nut and olive). Left
hand return right hand flow (viewed form inside
building/dwelling).
There is also a 1/2'' BSP drain cock tapping located on
the bottom front of heat exchanger (viewed from outside
building/dwelling).
The boiler must be used on a fully pumped
system only.

Note (1) The terminal should be positioned so as to
avoid products of combustion entering the
building.
Note (2) If the terminal is less than 2 metres above the
ground level, balcony or place to which any
person has access, the terminal must be
protected by a guard.
Note (3) If the terminal is fitted within 850mm of plastic
or painted gutter or within 450mm of painted
eaves a heat protection shield should be fitted
to the underside of the gutter of eaves.
Note (4) The flue must be positioned so that it does not
cause nuisance and permits the dispersal of
combustion products.
