Flue Installation

1.3.1 Siting the flue terminal
The flue must be installed in accordance with the
recommendations of BS. 5440-1:2000.
Pluming will occur at the terminal so terminal positions where
this could cause a nuisance should be avoided.
The air supply and the flue gas exhaust must meet the
applicable general regulations. Please consult the instructions
provided with the flue terminal kits prior to installation.
The boiler MUST be installed so that the terminal is exposed
to external air.
It is important that the position of the terminal allows the free
passage of air at all times.
Minimum acceptable spacing from the terminal to obstructions
and ventilation openings are specified in table 1.
If the terminal is fitted within 1000 mm of a plastic or painted
gutter or within 500 mm of painted eaves, an aluminium shield
of at least 1000 mm long should be fitted to the underside of
the gutter or painted surface.
If the lowest part of the terminal is less than 2 metres above the
level of the ground, balcony, flat roof or place to which any
person has access, the terminal must be protected by a guard.
Protective guards are available from Quinnell Barrett and
Quinnell, Old Kent Road, London.
Ensure that the guard is fitted centrally.
The flue assembly shall be so placed or shielded as to prevent
ignition or damage to any part of the building.
The air inlet/products outlet duct and the terminal of the boiler
MUST NOT be closer than 25 mm (1'') to combustible material.
Detailed recommendations on the protection of combustible
material are given in BS. 5440- 1:2000.
NOTE
It is absolutely essential to ensure, in practice,
that products of combustion discharging from
the terminal cannot re-enter the building or any
other adjacent building through ventilators,
windows, doors, other sources of natural
air infiltration, or forced ventilation/air-
conditioning.
If this could occur the appliance MUST be turned off (with the
owners permission), and labelled as unsafe until corrective
action can be taken.
Subject to modifications resulting from technical improvements!
