6 Installing the hood Installing the hood IMPORTANT  We recommend that two people carry out the installation. Pay attention to the procedure described in the assembly instructions. Preparation • Determine the exact location of the range hood. • Plan the route for venting exhaust to the outdoors (fig. ). • Plan the power connection prior to installation so that electrical wiring will not be visible afterwards. • House wiring location: The junction box is located on the top right side of the hood. Wiring should enter the back wall at least 20" above the bottom of the installation height, and within 3-3/8" to 4-3/4" of the right side of the centerline (fig. / ). • If open fireplaces are operated in the same room, ask your local chimney sweeper about the local regulations prior to installation. • If you are renting, then approval must be obtained from the owner of the property. • Attention! In order for the range hood to reach optimal performance, install it over the middle of the cooking area. • The following accessories are required to mount the range hood (not included): Exhaust duct Power drill with 3/16" and 1/8" bits Screwdriver Level Cable detector Measuring tape Duct tape fig. fig. 8 to 9 ft Installation height Center line 36" GB Ducting installation guidelines • Use the shortest and straightest duct route possible. • The wall breakthrough must be carried out by a professional prior to installing the range hood. Pay attention to the length of the exhaust hose when planning the wall breakthrough. The exhaust hose must reach the outer edge of the wall without any kinks. Important! If the exhaust hose leads through an outer wall, install a wall cap with damper or roof cap at the exterior opening (not delivered). This can be installed by the professional that performs the wall breakthrough. • For safety reasons, ducting should vent directly outdoors (not into an attic, underneath the house, into the garage or into any enclosed space). • Keep duct runs as short and straight as possible. • Duct fittings (elbows and transitions) reduce air flow efficiency. • Back to back elbow and "S" turns give very poor delivery and are not recommended. • A short straight length of duct at the inlet of the remote blower gives the best delivery. • Transition to duct from the integral blower or remote duct transition as close to the downdraft as is possible. • Use a suitable 6" round duct.
