2. VENTING AS A CHASE
When venting as a chase, follow all instructions included in Part 5
– Venting, Sections A – G of this manual, as well as the previous
Concentric Venting section. See Figure 19 for chase venting
demonstration.
NOTES:

vertical below overhang (overhang means top of building structure
and not two adjacent walls [corner of building]).
B. Typical installations require 12” minimum separation between
bottom of exhaust outlet and top of air intake.
C. Maintain 12” minimum clearance above highest anticipated
snow level or grade (whichever is greater).
D. Minimum 12” between vents when installing multiple vents.
E. 12” minimum beyond air intake.
F. Maintain 12” minimum clearance above highest anticipated
snow level or grade (whichever is greater).
