INSTALLATION
12. FOR BACK VENTING APPLICATIONS ONLY. IF NOT BACK VENTING, PROCEED DIRECTLY
TO STEP 13.
•
Note: Wall studs may interfere with back venting installations. Additional framing may be
required. It is necessary to cut duct access hole(s) in the wall prior to installing the hood.
•
If using a duct cover, this step may be done with the duct cover removed from the hood. The
duct cover must still be mounted to the hood before mounting the hood to the wall.
Method
1:
a) Hold the hood on the mounting strip by aligning the channel at the top of the back of the
hood over the wood mounting strip on the wall.
b) Place the appropriate elbow(s) on top of the hood in line with the hood exhaust collar(s). On
the wall, trace around the elbow(s). Remove the hood and elbow(s) from the wall.
c) Cut around the outside of the traced line(s), avoiding wall studs. Install the duct from the
outside of the home to the opening in the wall. Use HVAC foil tape (not grey cloth duct
tape) to seal joints.
d) Proceed to step 14.
Method
2:
a) Use the the connection diagrams (page 12), "BACK VENTING" on page 17 , and "VENT
ACCESSORIES" on page 18 as a guide. Install the duct(s) from the outside of the home to
the wall so they will meet the exhaust elbows to be used.
b) The end of the duct(s) should extend 1" past the ends of the elbows.
c) Proceed to step 14.
13. Check mount holes to wood strip, drill if needed:
a) Hang the hood on the mounting strip by aligning the channel at the top of the back of the
hood over the wood mounting strip on the wall.
b) While holding the hood in place, determine if the mounting holes in the channel at the top of
the back of hood align with the existing holes in the mounting strip. If they don't, mark the
hole locations on the mounting strip.
c) Remove the hood and drill 3/32" pilot holes in the center of the marks in the wooden
mounting strip to avoid splitting.
14. Mounting the Hood:
FOR BACK VENTING APPLICATIONS ONLY. IF YOU ARE NOT BACK VENTING, PROCEED
DIRECTLY TO STEP 15.
• If using a Hestan duct cover, it must be mounted to the hood using the provided fasteners
before continuing.
Method
1:
a) Place the appropriate elbow(s) on the top of the hood. Elbow(s) should be placed
with the non-crimped end(s) on the inside of the collar(s) of the exhaust outlet(s). Use
HVAC foil tape (not grey cloth duct tape) to seal joints.
b) Lift the hood up to the wall and hang the hood on the mounting strip, taking care to
properly align the duct connection(s) between the elbow(s) and the duct(s) in the wall.
c) Secure the hood to the mounting strip by installing the screws (previously removed
from the strip in Step 11) into the pilot holes drilled in Step 13.
•
Caution must be taken to avoid scratching the hood or ceiling.
