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.
Contact A.O. Smith for a suitable guard.
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 (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 fitted on an incline sloping down
towards the outside to prevent rainwater from coming in.
The appliance produces a white wisp of condensation (plumeing). This wisp of
condensation is harmless, but can be unattractive, particularly in the case of outlets in
outside walls.
The connection for the flue gas/air intake system is from standard concentric 80/125mm.
The flue gas duct for the 80/125 is a push fit connection and can be increased to 100/150
by means of an adapter fitting. See table 6.7.1.a for maximum flue length.
Cutting the pipe goes as follows:
- Cut just as much from the air intake part as from the flue gas part using a hand saw;
- Take off the burrs from the cutting edge to prevent cutting the seals;
When mounting the flue gas system, pay attention to the flow direction (See figue 6.7.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 fitting.
