4. You must consider the surroundings when terminating the vent
and air:
a. Position the vent termination where vapors will not damage
nearby shrubs, plants or air conditioning equipment or be
objectionable.
b. e ue products will form a noticeable plume as they con-
dense in cold air. Avoid areas where the plume could obstruct
window views.
c. Prevailing winds could cause freezing of condensate and
water/ice buildup where ue products impinge on building
surfaces or plants.
d. Avoid possibility of accidental contact of ue products with
people or pets.
e. Do not locate the terminations where wind eddies could aect
performance or cause recirculation, such as inside building
corners, near adjacent buildings or surfaces, window wells,
stairwells, alcoves, courtyards or other recessed areas.
f. Do not terminate above any door or window or under a deck.
Condensate can freeze, causing ice formations.
g. Locate or guard vent to prevent condensate damage to exterior
nishes.
5. Maintain clearances as shown in the illustrations in this manual
section. Also maintain the following:
a. Vent must terminate:
• At least 6 feet from adjacent walls.
• No closer than 5 feet below roof overhang.
• At least 7 feet above any public walkway.
• At lease 3 feet above any forced air intake within 10feet.
• No closer than 12 inches below or horizontally from any
door or window or any other gravity air inlet.
b. Do not terminate closer to 4 feet horizontally from any electric
meter, gas meter, regulator, relief valve or other equipment.
Never terminate above or below any of these within 4 feet
horizontally.
6. Locate terminations so they are not likely to be damaged by
foreign objects, such as stones or balls, or subject to buildup of
leaves or sediment.
7. Do not connect any other appliance to the vent pipe or multiple
boilers to a common vent pipe.
Completing the vent/air piping
1. Install vent/air penetrations as explained in the following pages
before installing vent and air piping from the boiler to the termi-
nations. Insert piping from boiler air and vent connections, then
attach exterior termination piping.
2. Follow instructions beginning on page71 to complete piping from
boiler to termination.
