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 con-

densate plume does not affect adjacent surfaces a clearance of 300 mm is

preferred.

4) BS 5440-1 It is recommended that a fanned flue terminal should be posi-

tioned 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.

8.1 Unpacking of Boiler

Stand the boiler carton upright.

Cut and remove the securing straps and lift off the carton

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

retaining 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.
