Alpine Wall Preparations
Alpine Wall Venting
Due to different ceiling height configurations, recommended height may not be
applicable.
CALCULATING VENT SYSTEM LENGTH
To calculate the length of the system you need, deduct the equivalent feet for each
vent piece used in the system from the recommended maximum duct run.
DUCT RUN CALCULATION
Recommended maximum run
8” or 3-1/4 x 10” duct 50 ft
Vent piece deduction
9 ft
Paper bags 5 ft
Plastic foam 7 ft
Wood 0 ft
Roof cap 0 ft
Duct Run Calculation example:
One roof cap, two 90° elbow, and one 45° elbow used:
0 ft + 9 ft + 9 ft + 5 ft = 23 ft used.
Deduct 23 ft from 50 ft, 27 ft maximum available for straight duct run.
VENTING METHODS
This range hood is factory set for venting through the roof or wall. Vent work can
terminate either through the roof or wall. To vent through a wall, use a 90° elbow.
IMPORTANT:
• NEVER exhaust air or terminate duct work into spaces between walls, crawl
spaces, ceiling, attics or garages. All exhaust must be ducted to the outside.
• Use metal/aluminum duct work only.
• Fasten all connections with sheet metal screws and tape all joints with certified
silver tape.
• Use caulking to seal exterior wall or roof opening around the cap.
WARNING: Moving and installing the range hood is a two person job. Spinal or
other bodily injuries could occur if it is not followed.

PREPARATIONS
1. Determine and mark the center line on the ceiling where the range hood will
be installed. Make sure there is proper clearance within the ceiling or wall for
exhaust vent.
2. Due to the weight and size of this unit, make sure that the support system or
framework being used is stable and secure in the wall.
3. Put a thick, protective covering over counter top, cook top, or range to protect
it from damage or dirt. Remove any hazardous objects around the area when
installing.
