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.
