Screen Installation
After connecting the intake air and exhaust vent pipes, it is required to install the included screens into the exhaust vent and intake pipe
terminations to prevent damages to the unit due to blockages. See Figure 20 for installation detail.
Figure 20 - Screen Installation - NOTE: Vent termination elbow is meant to be installed open end facing the ground. Orientation in Figure 20 is meant
to demonstrate proper Vent Screen installation ONLY.
NOTES:
A. For every 1” of overhang, the exhaust vent must be located 1” 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.
