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 ue terminal.
The effect of such ‘plumeing’ 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 at 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 tted 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 tted.
The ue must be terminated in a place not likely to cause a nuisance.
For horizontal sections, the outlet system should always be tted on an incline (50
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 tted on an incline sloping down
towards the outside to prevent rainwater from coming in.
The appliance produces a white wisp of condensate (plumeing). This wisp of condensation
is harmless, but can be unattractive, particularly in the case of outlets in outside walls.
For wall terminals a plume management kit is available as an option.
Cutting the pipe goes as follows:
- Cut just as much from the air intake part as from the ue gas part using a hand saw;
- Take off the burrs from the cutting edge to prevent cutting the seals;
When mounting the ue gas system, pay attention to the ow direction (See gue 6.8.e).
It is not permitted to mount a system upside down and will lead to complaints.
Use a soap solvent or special grease to simplify the tting.
