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 or vapor could cause damage or could be detrimental to the operation of regulators, relief valves, or other equipment.

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.
