Choice of installation site for side-wall flue termination
Choosing the right location for siting the terminal is critical
to proper functioning of the appliance. As well as the min-
imum clearances ( Fig. 14), the following rules must be
observed:

1. The termination should not face the prevailing wind
direction.
2. The termination must be installed in such a way that
the flue gases can disperse freely without re-entering
the building.
3. The termination must be at least 2 ft from adjacent
buildings and it must not be possible for the flue gas
to enter adjacent buildings.
4. Where the building adjoins public walkways, the ter-
mination must be located at least 7 ft above ground.
Make sure that freezing condensate does not consti-
tute a hazard.
5. The termination must never be located below building
overhangs, roof eaves, porches, enclosed spaces or
lower parts of the building which could prevent unre-
stricted outflow of the flue gases.
6. The termination must never be located within 3 ft of
inside corners of buildings and never less than 2 ft
from outside corners of buildings.
7. If there is a fan-assisted air intake vent within 10 ft, the
termination must be at least 3 ft above it.

8. The termination must be at least 4 ft below, 1 ft above
or 4 ft horizontally from doors, windows or air inlet
vents.
9. The termination must be at least 1 ft. above ground
and snow line, and protected from falling and accu-
mulating snow, ice, leaves or debris.
10. The termination should be at least 3 ft from any type
of building opening, oil tank filling or venting appara-
tus, and 6 ft from gas meters and similar equipment.
11. The position of the termination should be chosen so
that the last horizontal section of pipe slopes down-
wards to the inside by ¼" per ft. The flue terminal itself
must also be inclined at ¼" per ft to the inside so that
any condensate drains inwards.
