INSTALLATION
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO
PERSONS, OBSERVE THE FOLLOWING:
a) Installation work and electrical wiring must be done by qualified person(s) in accordance with
all applicable codes and standards, including fire-rated construction.
b) Sufficient air is needed for proper combustion and exhausting of gases through the flue
(chimney) of fuel burning equipment to prevent back drafting. Follow the heating equipment
manufacturer’s guideline and safety standards such as those published by the National Fire
Protection Association (NFPA), and the American Society for Heating, Refrigeration, and Air
Conditioning Engineers (ASHRAE) and the local code authorities.
c) When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden
utilities.
d) Ducted fans must always be vented to the outdoors.
TO REDUCE THE RISK OF FIRE, USE ONLY METAL DUCTWORK.
TO REDUCE THE RISK OF FIRE OR ELECTRICAL SHOCK, DO NOT USE THIS BLOWER WITH
ANY SOLID-STATE SPEED CONTROL DEVICE.
INSTALLATION DETAILS
1. Read all instructions thoroughly before beginning installation. Note: These instructions apply
to Hestan hoods only.
• See “DUCTING DO’S AND DON’TS” on page10
• Weight and size: For safe installation, at least two people should be present to lift and hold the
hood. For larger hoods and installations with duct covers, it is advisable to have a third person
present to assist.
• Back Venting: If venting out the wall behind the hood instead of venting through the ceiling,
see “BACK VENTING” on page16 for details.
2. When installing a wall mount range hood, it is recommended that the bottom edge of the hood
be located no more than 30” above the cooking surface for optimum performance.
3. Duct Preparation
IF THE HOOD IS TO BE “BACK VENTED”, PROCEED DIRECTLY TO
STEP 4.
a) Consult the connection diagrams (following) for further details on
exhaust outlet placement.
b) Install the duct(s) from the outside of the home down to the
location of the exhaust outlet(s) on the top of the hood allowing
room for the transition (if applicable). If a transition is used, install
duct down to the location of the transition outlet plus 1”. This will
allow the transition to engage 1” inside of duct.
c) Use foil HVAC tape (not gray cloth duct tape) to seal all joints. See
“VENT ACCESSORIES” on page17 for a listing of Hestan ducting
accessories.
Make sure that once the hood is mounted, the
motor cooling vents are not obstructed.
