INSTALLATION
4. IF THE HOOD IS TO BE "BACK VENTED", PROCEED DIRECTLY TO STEP 5.
Consult the connection diagrams (following) for further details on exhaust outlet placement.
Method 1: 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 or to the transition (if applicable).
• If a transition is used, install duct down to the location of the transition outlet plus 1"
[2.5 cm]. This will allow the transition to engage 1" [2.5 cm] inside of duct.
Method 2: Install the duct(s) from the outside of the home to the ceiling over the exhaust
outlet(s) on the hood. The end of the duct(s) should extend 1" [2.5 cm] below the
ceiling.
Use foil HVAC tape (not grey cloth duct tape) to seal all joints. See "Vent Accessories" on
page 19 for a listing of available Hestan ducting materials.
TRANSITION HEIGHTS:
Single and Dual Blower (WM1L + WM2L = 900 CFM): 6" round duct will connect directly to
the top of the hood; 8" round will connect directly to the top of the hood. If using
the optional multi-blower transition (AKVT6810, sold seperately), a 10" round duct
connects to it 17-1/2" above top of hood. See "VENT ACCESSORIES" on page 19
for details.
Two Dual Blowers (Two WM2Ls = 1200 CFM):
Two 8" round ducts connect directly to the top of the hood. If using the optional
multi-blower transition (AKVT8812, sold seperately), a 12" round duct connects to it
16-1/2" above top of hood. See "VENT ACCESSORIES" on page 19 for details.
