5.1
Location
1. The appliance may be fitted to any suitable wall
with the flue passing through an outside wall and
discharging to atmosphere in a position permitting
satisfactory removal of combustion products and
providing an adequate air supply. The appliance
should be fitted within the building unless otherwise
protected by a suitable enclosure ie. garage or
outhouse. (The appliance may be fitted inside a
cupboard. Cooling ventilation and insulation of the
cupboard are not required, see section 5.5.)
2. If the appliance is fitted in a room containing a bath
or shower reference must be made to the Current
I.E.E. Wiring Regulations and Building Regulations. If
the appliance is to be fitted into a building of timber
frame construction then reference must be made to
the Institute of Gas Engineers document UP7 (
“
Guide
for Gas Installation in Timber Framed Dwellings
”
).
3. Recommendations for flues are given in BS 5440
Part 1.
5.2
Minimum Clearances
(Fig. 8)
1. A flat vertical area is required for the installation of
the boiler.
2. These dimensions include the necessary
clearances around the appliance for case removal,
spanner access and air movement. Additional
clearances may be required for the passage of pipes
around local obstructions such as joists running
parallel to the front face of the appliance.
3. If fitted inside a cupboard the clearance of 500mm
shown is only necessary when the cupboard door is
open. A clearance of 5mm (
3
/
16
in) is required when
the door is closed.
5.3
Flue Position
1. For installations where the flue terminal is
inaccessible from the outside, an internal fitting kit is
available. This can be obtained free of charge from
your local merchant.
2. The following guide lines indicate the general
requirements for siting balanced flue terminals.
3. If the terminal is fitted within 1 metre (39in) of a
plastic gutter, within 500mm (19
1
/
2
in) of a painted
eave or a painted gutter, an aluminium shield of at
least 1 metre (39in) long should be fitted to the
underside of the gutter or painted surface. An air
space of 5mm (
3
/
16
in) should be left between shield
and gutter (Fig. 9).
4. If the terminal discharges onto a pathway or
passageway, check that combustion products will not
cause a nuisance and that the terminal will not
obstruct the passageway.
5. If the outer surface of an outside wall is of
combustible material, it should be protected by fitting
the flue trim provided.
