Sidewall direct vent with separate vent and air pipes must be terminated as follows:
Locate the intake air and exhaust vent terminations on the same plane (side) of the building.
Place the exhaust vent termination, so that it reaches 12" minimum above the down-turned
intake to avoid exhaust re-ingestion.
(Optionally) Raise the elevation of both terminations in “periscope style” after passing
through the wall, then to gain the required clearance configure as shown in
Figure 20 , Figure
21 , and Figure 22 .
Use a 45° elbow on the exhaust termination to launch the plume up and off the sidewall (for
protection of wall). A short piece of venting cut at 45° gives a horizontal termination protected
from wind loads (see
Figure 20 , Figure 21 , and Figure 22 ).
Recommend the use of a bird screen of ¼" stainless steel or plastic mesh (IPEX System
636 drain grate) to guard against foreign objects.
Caution
Refer to local code requirements or restrictions when installing concentric side wall
termination kits. Ensure that the termination and venting slope back to the appliance.
