Sidewall direct exhaust termination
Determine termination location
1. The vent termination must be installed as shown in Figure 29 and
in Figure 31, page 37.
2. The termination placement must comply with clearances and
limitations shown in Figure 28, page 35.
3. Locate the termination so is not likely to be damaged by foreign
objects, such as stones or balls, or subject to buildup of leaves or
sediment.
4. Ensure proper clearance above grade or snow line. Keep vents/
air intake area clear of accumulating snow.
5. Install the boiler in a location that allows proper routing of all vent
piping from the boiler vent connection to the selected sidewall
location.
Multiple vent terminations
1. When terminating multiple SVF
connection as described in this manual. See Figure 30, page 37
for typical layout.
2. Place wall penetrations to obtain minimum clearances shown in
Figure 29 for U. S. installations.
3. For Canadian installations, provide clearances required by Natural
Gas and Propane Installation Code - CAN/CSA B149.1 Installa-
tion Code and a ULC S636 compliant vent kit.

USE SWEEP ELBOWS FOR ALL VENT PIPING
WHEN POSSIBLE — Short-radius elbows cause
higher pressure loss, resulting in less allowable
vent/air piping length. See Figure 25, page 31
for maximum lengths and reductions required
for fittings.
1. Install a vent manufacturer adapter if needed to adapt to the
vent size/material being used. Follow all vent manufacturer's
instructions.
2. Slope vent piping toward the boiler — slope vent piping a mini-
mum of ¼ inch per foot in horizontal runs or larger per vent pipe
manufacturer's instructions.
3. Support piping independently of the boiler — Install pipe sup-
ports every 5 feet on both the horizontal and vertical runs. Install
a hanger support within 6 inches of any upturn in the piping. Or
follow vent pipe manufacturer's instructions.

1. Maintain the required dimensions of the finished termination
piping as shown in Figure 29, page 36.
