Read Before Starting Installation!
Inspect your range hood prior to installing!
Any cosmetic defects must be reported to us prior to installation.
Once this hood is installed, ICP will NOT accept any responsibility
for any cosmetic blemishes, scratches or dents in the Canopy.
Save all original packaging if you wish to return for any reason!
FIRST:
Check your local building and electrical codes.
WARNING:
To reduce the risk of fire or electrical shock, Do Not use any two speed motor units with a Solid State
control devise.
CAUTION:
To reduce the risk of fire or personal injury and to properly exhaust air, be sure to duct air to the
outside. DO NOT vent exhaust air into spaces within wall, attics, ceilings, crawl spaces or garages.
When venting to the outside make duct run as short and straight as possible. Avoid using elbows if at
all possible. If elbows are used, we recommend that the first elbow is 24” from vent opening on the
hood (minimum of 6”)and at least 24” between it and the next elbow. We strongly recommend no
more then two 90 degree elbows in any duct run. No Performance Warranty when used above
BBQ Style Grills.
DO NOT use duct pipe smaller than the outlet duct opening on the hood, this will reduce performance
and void the warranty. DO NOT use flex ducting. Also, use either a Roof Cap or Wall Cap to end
run. Be sure that all joints are taped securely in place. It is essential to have the proper distance
between the bottom of the range hood and the cooking surface below. In most cases the cooking
appliance manufacturers specifications will establish the fire safe minimum distance required, although
there are other factors to consider:
 Local Building Codes
 Cross directional air movements ie: open windows, air conditioning/heating outlets, cooling fans,
etc.
 Overall size of the cooking appliance and surrounding countertop surfaces.
 Range hood model selected.
For best performance distance between cooking surface and the bottom of the hood is 30” and 36”.
Check local codes and appliance specifications. Keep in mind, increasing the distance will decrease the
performance.
TWIN UNITS ONLY - Transitioning two pipes into one is NOT recommended. CFMs are reduced
by 25% and the Performance Warranty will be void.
