Adams Condensing Oil-Fired Furnace - Manual (Page 10)

Sidewall Vent System
a) Sidewall vented products are
susceptible to wind conditions that can
effect combustion. To minimize the
effects of wind, exhaust and air inlet
terminations must penetrate the same
wall or vertical surface. In addition,
the length of the exhaust and air inlet
pipes must be roughly equivalent.
b) Condensation from a sidewall vented
appliance may cause paint and other
surface coatings to deteriorate. In
addition, soot stains may appear on
surrounding surfaces if the furnace is
not properly maintained.
c) See Figure 2 for an illustration of
clearances for location of exit
terminals for direct-vent, sidewall
venting systems.
d) The vent system shall terminate at
least 3 feet above any forced air inlet
located within 10 feet. NOTE: This
does not apply to the combustion air
inlet of 3 direct-vent appliance.
e) Provide a minimum of 1 foot distance
from any door, operable window, or
gravity air inlet into any building.
f) Do not locate the exhaust termination
directly under an operable window.
g) Provide a minimum of 1 foot clearance
from the bottom of the exhaust
termination above the expected snow
accumulation level. Snow removal
may be necessary to maintain
clearance.
h) Provide 4 feet horizontal clearance
from electrical meters, gas meters, air
conditioning condensers or other
external equipment. In no case shall
the exit terminal be above or below
the aforementioned equipment unless
a 4 foot horizontal distance is
maintained.
i) Do not locate the exit termination over
public walkways where condensate
could drip or freeze, causing a hazard
or nuisance. ,
i) When the exhaust termination is
adjacent to a public walkway, it is to
be located at least 7 feet above grade.
K) Do not locate exhaust termination
directly under roof overhangs to
prevent icicles from forming.
I) Provide 3 feet clearance frtxn the
inside corner of adjacent walls.
The vent termination of a non-direct vent
application must terminate at least 4 feet
below, 4 feet horizont^ly from, or 1 foot
above any door, window, or gravity air inlet
into any building.
