f. Provide 4 feet horizontal clearance from
electrical meters, gas meters, gas
regulators and relief equipment. In no
case shall the exit terminal be above or
below the aforementioned equipment
unless the 4 foot horizontal distance is
maintained.
g. Do not locate the exhaust over public
walkways where condensate could drip
and/or freeze and create a nuisance or
hazard.
h. The vent for this appliance shall not
terminate over public walkways; or near
soffit vents or crawl space vents or other
area where condensate or vapor could
create a nuisance or hazard or cause
property damage; or where condensate

i. Do not locate the exhaust directly under
roof overhangs to prevent icicles from
forming.
j. Provide 4 feet clearance from the inside
corner of vertical walls, chimneys, etc., as
well as horizontal corners created by roof
overhangs.
2. Determine air intake vent location.
a. Provide 1 foot clearance from the bottom
of the intake air vent and the level of
maximum snow accumulation. Snow
removal may be necessary to maintain
clearances.
b. Do not locate intake air vent in a parking
area where machinery may damage the
pipe.
c. When venting with a two pipe system,
maximum distance between intake air
vent and exhaust vent is 6 feet (1.8 m).
Minimum distance between exhaust vent
and intake air vent on single heater is 8”
(0.2 m) center-to-center. Minimum
distance between exhaust vents and
intake air vents on multiple heaters is 8”
(0.2 m) center-to-center.
