DIRECT VENT — Sidewall Vent and Air Plate (Category IV)
1
Determine Termination Location
The vent and air plates must be installed as shown
in Figure 50, page 58 The termination placement
must comply with clearances and limitations shown in
Figure 36, page 47
2
1 Install the termination in a location where damage
from foreign objects and buildup of leaves or
sediment is unlikely
2 Ensure proper clearance above grade or
snow line Keep vents and air area clear of
3
accumulating snow
3 Install the boiler in a location that allows proper
routing of all vent piping from the boiler vent
connection to the selected sidewall location
WARNING
!
4
Locate the termination such that the total vent
piping from the boiler to the termination will
not exceed the maximum length given in Figure
22, page 34 for Category IV venting. Failure
to comply can result in severe personal injury,
death, or substantial property damage.
5
IMPORTANT
Read and follow all instructions in this manual. Do
not proceed with vent installation until you have
read pages 27-38 & 47. Comply with all vent
system manufacturer's instructions.

Multiple Vent Terminations
When terminating multiple SVF boilers, terminate each
vent and air connection as described in this manual
See Figure 48 for adjacent termination clearances
WARNING
!
7
All vent and air inlet pipes must terminate at the
same height to prevent severe personal injury,
death, or substantial property damage.

12" minimum between edge of vent
opening and adjacent termination
• For U S installations, place wall penetrations to
obtain minimum clearances shown in Figure 48 and
Figure 36, page 47
• In Canada, provide clearances required by the
Installation Code – CAN/CSA B149 1 or B149 2
Use a ULC S636-compliant vent kit
• The air inlet of a boiler is part of a direct vent
connection. It is not classified as a forced air intake
with regard to spacing from adjacent boiler vents
