Advance Planning
USING DUCT COVER ACCESSORIES
To avoid unsightly gaps, plan the hood installation
height for duct cover use. Use the following formula
to calculate the need for one or more duct covers
and to ensure a trouble free installation.
9 ft. ceilings
: When the hood is installed 30"
above the cooking surface, order two 12" duct
cover accessories.
10 ft. ceilings
: When the hood is installed
36" above the cooking surface, order two 12"
and one 6" duct cover accessories.
We recommend that the vent hood and decorative
duct cover (if used) be on site before final framing and
wall finishing. This will help to accurately locate studs,
ductwork and electrical service.
• Read these examples carefully to determine the need
for one or more 6" or 12" duct covers.
A - B = C
A = Countertop to ceiling height.
B = Gap at the top of the hood to the ceiling.
C = Hood installation height - Plus 18" hood height.
NOTE:
Dim. C should be between 48" and 54" (for a
30" to 36" installation height). Raise or lower the hood
installation height to allow use of one or more 6" and
12" duct covers.
8 ft. ceilings:
When the hood is installed
30" above the cooking surface and there is
no soffit or upper cabinetry, order one 12"
duct cover accessory.
