Fig. 3.8 Flue termination
Note
Vertical flues must not terminate within
600 mm of an openable window, air vent or any
other ventilation opening.
The flue assembly shall be so placed or shielded as to
prevent ignition or damage to any part of the building.
Terminal position
Directly below an opening, above an opening or hori-
A
zontal to an opening, air brick, opening window, 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
From an opening in the car port (e.g. door, window)
J
into the dwelling
K Vertically from a terminal on the same wall
L Horizontally from a terminal on the same wall
M Distance from adjacent for vertical Flue

Note
In addition, the terminal should not be nearer
than 150 mm to an opening in the building fab-
ric formed for the purpose of accommodating a
built-in element such as a window.
BS 5440–1: It is recommended that the fanned flue ter-
minal should be positioned as follows:
a) at least 2 m from an opening in the building directly
opposite, and
b) so that the products of combustion are not directed
to discharge across a boundary.
1) Dimensions 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. 3.9.
2) 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 surfaces a clearance of 300 mm is

preferred. For IE, recommendations are given in the
current edition of IS 813.

It is not necessary to have an air vent in the room or

internal space in which the boiler is installed.

The boilers are very high efficiency appliances. As a
consequence the heat loss from the appliance casing
1500
during operation is very low. For cupboard or compart-
300
ment installations it is therefore not necessary to pro-
500
vide any high or low level permanent air vents for cool-
ing purposes.

Electrical supply

A 230 V, ~ 50 Hz single phase electricity supply fused to
3 Amp. must be provided in accordance with the latest
edition of BS 7671 (IEE Wiring Regulations) and any
other local regulations that may apply. In IE reference
should be made to the current edition of the ETCI rules.
The method of connection to the mains electricity sup-
ply must provide a means of completely isolating the
boiler and its ancillary controls. Isolation is preferably
by the use of a fused three pin plug and unswitched
shuttered socket outlet, both complying with the
requirements of BS 1363. Alternatively, a 3 Amp. fused
double pole switch with a 3 mm contact separation on
both poles may be used.
Danger!
This appliance must be earthed.
