STEP 2 MARK MOUNTING
LOCATION
• The base is designed to be mounted to studs 16” on
center or to other suitable exterior surfaces. Use the
dimensions shown to determine the location of the
ducting and wiring through the wall.
OR
• Place the base against the exterior wall and mark
the 6 mounting locations, the 6” duct location and
the hole for the wiring. Use pencil or chalk.
• The bottom of the base assembly must be 10” Min.
above the ground. There should be no obstructions
to the discharge from the damper.
• Cut a 6-1/8” Dia. hole in the vertical structure to
accommodate a 6” round duct. Cut another hole for
the wiring.
• Drill 6 pilot holes through the wall for the 5/16”
fasteners (not supplied). Use fasteners appropriate
for the type of construction.
CAUTION
When cutting or drilling into a wall or ceiling, do not
damage electrical wiring or hidden utilities.
PRUDENCE

plafond, il faut prendre soin de ne pas endommager
les fils électriques et autres services cachés.
• Check for interference with floor joists and stud
walls. If necessary, locate the base to provide a
secure installation.
• Place a 6” round duct through the hole extending
approximately 3” from the wall to provide a proper
seal with the blower. Secure the duct to the building
structure to prevent it from being pushed back when
the blower is installed.
