Adams Condensing Oil-Fired Furnace operation manual Sidewall Vent System

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.
