Preparation and Setup
• Support the weight of the ducting with sheet-metal
screws as needed.
• To prevent backdraft, a damper at the duct outlet may be
required.
WARNING
• Electricity to the range hood should be installed only by a
licensed electrician.
• Observe all governing codes and ordinances during site prep-
aration and installation. Contact your local building depart-
ment for details.
• Improperly anchoring the hood to the wall may cause per-
sonal injury if unit falls.
• To prevent electric shock and property damage, do not drill or
cut in the vicinity of plumbing and electrical wiring.
• Use the
temporary
holding brackets to support the hood only
until permanent anchoring is secured.
Preparing the Mounting Location
Holding brackets and hardware are provided to temporarily
support the hood during the permanent installation process.
• (If mounting the hood to brick or masonry) Select anchors
that can support the hood’s full weight.
• Ensure the mounting surface is properly reinforced to
support the hood’s full weight.
• If mounting the unit to drywall or a plastered surface,
install a reinforced mounting block between the studs.
• Attach screws directly to the studs and cabinets if they
align with the mounting holes in the hood back/top.
