Installation instructions E-SHR series page 12
The terminal should be located where dispersal of
combustion products is not impeded and with due regard
for the damage or discolouration that might occur to
building products in the vicinity (see fig 10).
In certain weather conditions condensation may also
accumulate on the outside of the air inlet pipe. Such
conditions must be considered and where necessary
insulation of the inlet pipe may be required.
In cold and/or humid weather water vapour may condense
on leaving the flue terminal. The effect of pluming steam
must be considered.
The terminal must not be located in a place where it is
likely to cause a nuisance.
For protection of combustibles, refer to IS 813 section
9.10.1. where the terminal is less than 2m (6.6ft) above a
pavement or platform to which people have access
(including) any balcony or flat roof the terminal must be
protected by a guard of durable material.
A suitable guard is available from the country distributor.
Where a terminal is fitted below a window
which is hinged at the top, and where the
hinge axis is horizontal, and the window
opens outwards, the terminal shall be 1m
below the bottom of the window opening.
If the boiler is to be located under stairs, a
smoke alarm meeting the requirements of I.S.
409 or equivalent must be fitted.
The flue must be terminated in a place not
likely to cause a nuisance.
For horizontal sections, the outlet system should always
be fitted on an incline (30 mm/m) sloping down towards
the appliance so that no condensation water is able to
accumulate in the outlet system. The chances of icicles
forming on the roof outlet is minimised by causing the
condensation water to run back towards the appliance. In
the case of horizontal outlets the inlet system should be
fitted on an incline sloping down towards the outside to
prevent rainwater from coming in.
Fitting an additional condensation collection device in the
outlet system is surplus to requirement.
The appliance produces a white wisp of condensation.
This wisp of condensation is harmless, but can be found
to be unpleasant, particularly in the case of outlets in
outside walls.
For further information regarding the supply
range of the exhaust and supply system
please contact the country distributor.
6.9 Air supply
It is NOT necessary to have a purpose provided air vent in
the room or internal space in which the boiler is installed.
Neither is it necessary to ventilate a cupboard or
compartment in which the boiler is installed, due to the
extremely low surface temperature of the boiler casing
during operation. Therefore the requirements of BS 6798,
Clause 12, and BS5440:2 may be disregarded.
The appliance is not suitable as an "open"
appliance. This means that combustion air
should always be obtained through a direct
connection.
