TERMINATION LOCATION GUIDELINES
1. Mount intake hood 12 inches above finished
grade. If mounting on the side of a building
prone to drifting snow, mount 12 inches
above the snow line.
2. Mount at least 12 inches away and on the
same wall if sidewall venting.
3. Always mount with the inlet vent termination
opening pointing down.
INLET VENT TERMINATION INSTALLATION
1. Cut a 4 1/4" diameter hole through the
sidewall of the building.
2. Slide the inlet vent pipe through the hole and
fasten to the wall with appropriate fasteners.
Seal the edges of the mounting plate with a
silicone sealant or equivalent.
DUCT WORK INSTALLATION
1. Duct length distance, a maximum of 30
linear feet of standard duct pipe and two (2)
90o elbows. Subtract 7 feet from the
maximum linear feet for every 90o elbow
added. Maximum linear footage will be less
for flex duct. Consult manufacturer for
equivalent lengths.
2. Route duct work from the VRV tee to the inlet vent termination with as minimum a number of
elbows as possible.
3. Secure and support the duct work for the design and weight of the material used, to prevent
physical damage and separation of joints. For guidelines refer to recognized national building
codes or according to any local codes.
4. To reduce uncontrolled air leakage into the duct, tape all joints and seams using standard duct
tape.
Note: To prevent sweating on the outside of the duct, when operating in areas that have -10oF or
below design temperatures. Insulate the duct work at least 10 feet from the inlet vent termination.
