LENGTHS
Use only the vent materials and kits
listed in Figure 27, page 23 . Provide pipe
adapters if specifi ed.
1. Locate the termination 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 .
$ETERMINETERMINATIONLOCATION
1. The vent/air cap must be installed as shown in
Figure 41, page 33 .
2. The termination must comply with clearances and
limitations shown in Figure 28, page 25 .
3. Locate the termination so it is not likely to be
damaged by foreign objects, such as stones or balls,
or subject to buildup of leaves or sediment.

TERMINATIONS
1. When terminating multiple boilers, terminate each
vent/air connection as described in this manual.
All vent pipes and air inlets must
terminate at the same height to avoid
possibility of severe personal injury,
death or substantial property damage.
2. Place wall penetrations to obtain minimum
clearance as shown in for U. S. installations. 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.
For terminations of other appliances,
provide at least the clearance shown. The
installation must also comply with the
manual for the other appliances.

3TEP
Install the boiler in a location that allows proper routing of all vent
and air piping to the selected sidewall location.
3TEP
Make sure the selected sidewall termination location complies with
Figure 28, page 25
. (Multiple boiler sidewall plates must also comply
with Figure 39, page 33 .)
3TEP
Use only the vent materials listed in Figure 27, page 23 . Provide pipe
adapters where required.
3TEP
Vent piping and air piping lengths must not exceed the values shown
in
Figure 26, page 22
.
3TEP
Prepare the sidewall penetrations and secure the sidewall plates as
instructed in this section. See “Install Weil-McLain vent/air cap” on
page 33 .
3TEP
The Weil-McLain plate termination must be installed before piping
from the boiler to the termination.
3TEP
Install vent and air piping between the boiler and the vent/air
termination plate. Slope horizontal piping downward toward the boiler
at least 1/4 inch per foot. See page 27 for general guidelines.
3TEP
Install pipe supports every 5 feet on both the horizontal and vertical
runs, or per vent pipe manufacturer’s instructions.
See notices at left and page 21 .
3TEP
Install a hanger support within 6 inches of any upturn in the piping,
or per vent pipe manufacturer’s instructions.
