Direct Vent - Vent Installation - Sidewall; Termination Fittings - Sidewall - IDEAL Exalt Solo 110 Manual

CHAPTER 2 - DIRECT VENT INSTALLATION OF VENT/AIR PIPING
d. Avoid locations where prevailing winds could
affect the performance of the boiler or cause
recirculation of the flue gases, such as inside
corners of buildings, near adjacent buildings,
vertical surfaces, window wells, stairwells,
alcoves, courtyards, or other recessed areas.
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.
6. 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, 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 or within 4
feet [1.2 m] horizontally.
g. A minimum of 12" [30.5 cm] or a maximum of
24" [61 cm] beyond the exterior wall.
h. 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.
7. The edge of the combustion air termination
coupling must extend 1" [2.5 cm] beyond the
exterior wall as shown in Fig 6 through Fig. 8 on
page 17.
8. 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.
9. Do not connect any other appliance to the vent
pipe or multiple boilers to a common vent pipe.

2.2.2 Direct Vent - Vent Installation - Sidewall

1. Vent and Combustion Air Penetration
• Vent pipe penetration through combustible or
non-combustible wall material must maintain a
minimum 1/4" [6mm] 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.
• 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 installer must use a galvanized metal thimble
for the vent pipe penetration.
3. Locate the vent and combustion air pipe
penetrations to provide clearances as described in
Fig. 6 through Fig. 8 on page 17.
4. The installer must comply with all local codes for
isolating the vent and combustion air pipes as they pass
through floors and walls.
5. The installer must seal all exterior openings around
penetration with an exterior silicon caulk.

2.2.3 Termination Fittings - Sidewall

1. The vent and combustion air terminations must
include a factory supplied "bird screen" installed as
shown in Fig. 9 and Fig. 10 on page 18.
2. The combustion air piping must terminate using a 90º
elbow as shown in Fig. 6 through Fig. 8 on page 17.
3. The vent piping can terminate:
• Using a 90º elbow as shown in Fig. 6 or Fig. 8 on
page 17.
• Using a coupling as shown in Fig. 7 on page 17.
The vent termination must be installed 12" [30.5 cm]
minimum above the combustion air termination.
WARNING
Do not extend the vent pipe outside the
sidewall beyond the dimensions shown in
Fig. 6 through Fig. 8 on page 17. Extended
exposure of the vent pipe could cause
condensate to freeze and block the vent pipe,
resulting in substantial property damage,
serious injury, or death.
