4.4.4 Flue termination

The following details refer to both flue systems.
a. The terminal must be positioned such that the pro-
ducts of combustion can disperse freely at all times.
b. In certain weather conditions a plume of water
vapour may be visible from the flue terminal.
Positions where this could be a nuisance should be
avoided.
c. If the terminal is fitted less than 2 m above a bal-
cony, above ground or above a flat roof to which
people have access then a suitable terminal guard;
280 mm x 280 mm x 270 mm deep, must be provi-
ded and fitted (made by Tower Flue Components,
Tonbridge, TN9 1TB).
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 for fan-assisted flue
(minimum distance)
1)
A Directly below an openable, 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 (below car port roof)
E From vertical drain pipes and soil pipes
F From internal or external corners
G Above ground or balcony level
H From a surface or boundary facing a terminal
H From a terminal facing a terminal
J From an opening in a car port (e.g. door, window)
into a dweling
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.
* 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 buil-
ding directly opposite, and b) so that the products of combustion
are not directly directed to discharge across a boundary.

4.5 Air supply

Detailed recommendations for air supply are given in BS
5440: Part 2. It is not necessary to have an air vent in
the room or internal space in which the boiler is installed.

4.6 Cupboard or compartment ventilation

The boilers are very high efficiency appliances. As a con-
sequence the heat loss from the appliance casing during
operation is very low. For cupboard or compartment in-
stallations it is therefore not necessary to provide any high
or low level permanent air vents for cooling purposes.

4.7 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 BS7671 (IEE Wiring Regulations) and any other
local regulations that may apply.
The method of connection to the mains electricity supp-
ly must provide a means of completely isolating the boi-
ler and its ancillary controls. Isolation is preferably by
the use of a fused three pin plug and unswitched shutte-
red socket outlet, both complying with the requirements
of BS 1363. Alternatively, a 3 Amp. fused doublepole
switch with a 3 mm contact separation on both poles
may be used.
