Terminal position
1)
A Directly below an opening, above an opening
or horizontal to an opening i.e. air brick, opening
window or other, etc
B Below gutters, soil pipes or drain pipes
C Below eaves
D Below balconies
E From vertical drain pipes and soil pipes
F From internal or external corners
G Above ground, roof or balcony
H From a surface facing a terminal
I From a terminal facing a terminal
K Vertically from a terminal on the same wall
L Horizontally from a terminal on the same wall
M Distance from adjacent wall for vertical Flue
1) In addition, the terminal should not be nearer than 150mm to an
opening in the building fabric formed for the purpose of
accommodating a built-in element such as a window.
2) Dimension B,C and D; These clearances may be reduced to
25 mm without affecting the performance of the boiler. In order
to ensure that the condensate plume does not affect adjacent
surfaces the terminal should be extended as shown in Fig 7.4.
3) Dimension F; This clearance may be reduced to 25 mm without
affecting the performance of the boiler. However, in order to
ensure that the condensate plume does not affect adjacent surfa-
ces a clearance of 300 mm is preferred.
4) BS 5440-1 It is recommended that a fanned flue terminal should
be positioned as follows:
a) at least 2m from an opening in a building directly opposite, and
b) so that the products of combustion are not directly directed to
discharge across a boundary. For IE, recommendations are given
in the current edition of IS 813.

8 Installation Preparation

8.1 Unpacking of Boiler

Stand the boiler carton upright.
Cut and remove the securing straps and lift off the car-
ton sleeve. Place aside the flue adaptor and connections
pack until required.
Carefully lay the boiler on its back, remove the two front
casing panel securing screws and lift off the panel from
two retaining lugs, see diagram 8.1.
Remove the two inner casing panel securing screws at
the bottom front of the panel, then lift off the two retai-
ning lugs, see diagram 8.2.

8.2 Using boiler template

Fix the paper template to the wall ensure that the
template is vertical.
The template shows
- The position of the fixing holes for the boiler mounting
bracket (1).
- The position of the connections.
- The position of the flue exit hole.
Mark the position of the top hanging bracket fixing
holes.
Drill 2 holes to accept the wallplugs/screws supplied for
the hanging bracket.
Note!
Use alternative fixing holes where necessary.
