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
a 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.
j)
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 from the
inside corner
of
adjacent walls.
The
vent termination
of
a non-direct
vent
application
must
terminate
at
least 4 feet
below, 4 feet horizontally from,
or
1 foot
above any door, window,
or
graVity
air
inlet
into any bUilding.
