Choose an appropriate location for the exterior hoods:
• At least 6 feet between both hoods to avoid cross-contamination
• At least 18 inches away from the ground
Refer to Fig. 11 for proper connection method of the insulated ducts to
the hoods. An “Anti-Gust Intake Hood” should be installed in regions
where a lot of snow is expected to fall.

UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or
improper operation.
- If ducts have to go through an unconditioned space (e.g.: attic),
always use insulated ducts to avoid condensation and mold.
- Do not use screws to connect the ducts or transitions to the
ports. They could interfere with proper damper operation.
