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
page19 for a listing of available Hestan ducting materials.

Single and Dual Blower (WM1L + WM2L = 900 CFM): 6” round duct will connect directly to

Two Dual Blowers (Two WM2Ls = 1200 CFM): Two 8” round ducts connect directly to the
