Sidewall direct exhaust termination
Determine termination location
1. The vent termination must be installed as shown in Figure 27
and in Figure 29, page 34.
2. The termination placement must comply with clearances and
limitations shown in Figure 26, page 32.
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 SlimFit boilers, terminate each
vent connection as described in this manual. See Figure 28,
page 34 for typical layout.
2. Place wall penetrations to obtain minimum clearances shown
in Figure 27 for U. S. installations.
3. For Canadian installations, provide clearances required
by Natural Gas and Propane Installation Code - CAN/CSA
B149.1 Installation Code and a ULC S636 compliant vent kit.

cause higher pressure loss, resulting in less allow-
able vent/air piping length. See Figure 24, page 29
for maximum lengths and reductions required for
fittings.
1. Install the vent manufacturer's SlimFit Vent Adapter in the
boiler vent outlet. Follow all vent manufacturer instructions.
2. Install a vent manufacturer reducer if needed to adapt to the
vent size being used.
3. Slope vent piping toward the boiler — slope vent piping a
minimum of ¼ inch per foot in horizontal runs or larger per
vent pipe manufacturer's instructions.
4. 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.
Install vent termination elbow
1. Maintain the required dimensions of the finished termination
piping as shown in Figure 27, page 33.
Use only the vent materials and kits
listed in Figure 22, page 25.
Read and follow all instructions in this
manual. DO NOT proceed with vent in-
stallation until you have read page 23
through page 32
Locate the termination such that the total
vent piping from the boiler to the termi-
nation will not exceed the maximum
length given in Figure 24, page 29.
Comply with all vent system manufac-
turer's instructions
Provide a vent manufacturer's SlimFit
Vent Adapter and reducer (if needed) at
the boiler vent connection.
