Direct Vent - Vent Installation - Through The Roof; Direct Vent - Combustion Air Installation - Sidewall - IDEAL Exalt Solo 110 Manual

CHAPTER 2 - DIRECT VENT INSTALLATION OF VENT/AIR PIPING
e. Do not terminate the vent above doors or
windows, flue condensate could freeze causing
ice formations.
f. Locate the vent termination to prevent possible
condensate damage to exterior finishes.
g. Avoid locations of possible accidental contact
of flue vapors with people or pets.
5. The vent termination must also maintain the
following clearances; as shown in Fig. 2 on page
13.
a. At least 3 feet [0.9 m] from adjacent walls
b. At least 3 feet [0.9 m] below roof overhangs
c. At least 7 feet [2.1 m] above any public walkways
d. At least 3 feet [0.9 m] above any forced air intake
within 10 feet [3 m] (does not apply to the
combustion air inlet of a direct vent appliance).
e. No closer than 12" [30.5 cm] below or horizontally
from any door or window or gravity air inlet.
f. Must be at least 4 feet [1.2 m] from any electric
meters, gas meters-regulators, relief valves or
other equipment. Never terminate the vent
above or below any of these items within 4 feet
[1.2 m] horizontally.
g. A minimum 12 inches [30.5 cm] horizontal spacing
from other fan assisted appliance vents. Never
terminate the vent above or below any fan assisted
vent within 12 inches [30.5 cm] horizontally.
6. The edge of the combustion air termination
coupling must extend 1" [2.5 cm] beyond the
exterior wall as shown in Fig. 12 on page 19.
7. Locate the vent and combustion air terminations in a
manner to protect from damage by foreign objects,
such as stones, balls, or buildup of leaves or sediment.
8. Do not connect any other appliance to the vent
pipe or multiple boilers to a common vent pipe.
2.3.2 Direct Vent - Vent Installation - Through
the Roof
1. Vent pipe penetration through combustible or
non-combustible wall material must maintain
a minimum 1/4" [6 mm] clearance for 3" [80 mm]
PVC/CPVC vent or 1" [2.5 cm] for 2" [60 mm] PVC/
CPVC vent. The diameter of the penetration hole
must be 4" [10.2 cm] minimum for 2" [60 mm] and 3"
[80 mm] pipe. When using Polypropylene or AL29-
4C® Stainless Steel Vent refer to vent manufacturer's
Installation Instructions for clearances.
2. The installer must use a galvanized metal thimble
for the vent pipe penetration.
3. The vent must terminate 12" [30.5 cm] (18" [45.7 cm]
in Canada) above the highest anticipated snow level.
4. The installer must comply with all local codes for
isolating the vent pipe as it passes through floors,
ceilings and roofs.
5. The installer must provide adequate flashing and
sealing boots sized for the vent pipe.
2.3.3 Direct Vent - Combustion Air Installation
- Sidewall
1. Combustion air pipe penetration can maintain zero
clearance. The diameter of the penetration hole
should be 2 3/8" [6 cm] minimum for 2" [60 mm]
pipe or 3 1/2" [8.9 cm] minimum for 3" [80 mm] pipe.
2. The combustion air termination must be installed
12" [30.5 cm] minimum above grade / highest
anticipated snow level as shown in Fig. 6 or Fig. 8
on page 17.
3. The installer must comply with all local codes
for isolating the combustion air pipe as it passes
through floors and walls.
4. The installer must seal all exterior openings around
penetration with an exterior silicon caulk.
