FIRED WATER BOILER
DIRECT VENT —
Use only the vent materials and kits
listed in Figure 27, page 23 . Provide pipe
adapters if specifi ed.
1. Locate the terminations such that the total air
piping and vent piping from the boiler to the
termination will not exceed the maximum length
given in Figure 26, page 22 .
For polypropylene applications, See
venting and air piping notes on page 21 .
For AL29-4C vent pipe applications,
See venting and air piping notes on
page 21 .
1. The air and vent terminations must be installed as
shown in Figure 42 .
2. The terminations must comply with clearances and
limitations shown in Figure 28, page 25 .
3. Locate the 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.
1. When terminating multiple boilers, terminate each
vent/air connection as described in this manual.
Terminate all vent pipes at the same
height and all air pipes at the same height
to avoid possibility of severe personal
injury, death or substantial property
damage.
2. Place roof penetrations to obtain minimum
clearance of 12 inches between edge of air intake
elbow and adjacent vent pipe of another boiler
for U. S. installations (see Figure 43, page 35 ). For
Canadian installations, provide clearances required
by CSA B149.1 or B149.2 Installation Code and a
ULC S636 compliant vent kit.
3. The air inlet of a boiler is part of a direct vent
connection. It is not classifi ed as a forced air intake
with regard to spacing from adjacent boiler vents.

Read and follow all instructions in this manual.
Install the boiler in a location that allows proper routing of all vent
and air piping to the selected sidewall location.
Make sure the selected vertical termination location complies with
Figure 28, page 25 . (Multiple boiler terminations must also comply
with Figure 43, page 35 .)
Use only the vent materials listed in Figure 27, page 23 . Provide pipe
adapters where required. Vent piping and air piping lengths must not
exceed the values shown in Figure 26, page 22 .
Prepare the vertical penetrations and secure penetration components
as instructed in this section. See "Prepare roof penetrations" on page 35
and "Termination and fi ttings" on page 35 .
The air piping must terminate in a 180-degree return bend or
Install vent and air piping between the boiler and the vertical
terminations. Slope horizontal piping downward toward the boiler at
least 1/4 inch per foot. Install pipe supports every 5 feet on both the
horizontal and vertical runs. Install a hanger support within 6 inches
of any upturn in the piping. See page 27 for general guidelines. Also
comply with vent pipe manufacturer's instructions.
See notices at left and page 21 .
Insert the vent and air piping through the vertical penetrations and
secure the termination fi ttings.
Maintain clearances shown above. Vent and air terminations must be
fi tted with a bird screen as shown.
