PART 7: VENTING, COMBUSTION AIR & CONDENSATE REMOVAL

(CONTINUED)

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. When adjacent to a public walkway,

locate exit terminal at least 7 feet above

grade.

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.
