Whirlpool Ventilation Hood - Manuel (Page 6)

6
Because of the size and weight of this island hood, the chimney
support must be securely attached to the ceiling.
■ For plaster or drywall ceilings, the chimney support must be
attached to joists. If this is not possible, you must build a
support structure behind the plaster or drywall. The support
structure must be able to support 80 lbs (36.3 kg).
■ Do not cut a joist or stud unless absolutely necessary. If a
joist or stud must be cut, then a supporting frame must be
constructed.
■ Before making cutouts, make sure there is proper clearance
within the ceiling or wall for exhaust vent.
■ We recommend the hood be installed 30"–36" (76.2 cm –
91.4 cm) above the countertop.
■ Check your ceiling height and the hood height maximum
before you select your hood.
Hood Height Calculations
1. Select a hood preference height (P) that is comfortable for the
user. 30"– 36" (76.2 cm – 91.4 cm) is recommended.
2. Calculate the hood height for your installation (H = K – C – P ).
3. Confirm that the dimension (H) is within the minimum to
maximum dimensions. See “Product Dimensions” in the
“Location Requirements” section.
4. Calculate the chimney structure height (S = H –1 ³⁄₄" [4.4 cm]).
K = ceiling height
C = countertop height
P = preferred hood height –
30"–36" (76.2 cm – 91.4 cm)
is recommended
H = K – C – P

Electrical Requirements
IMPORTANT: The hood must be electrically grounded in
accordance with local codes and ordinances, or in the absence of
local codes, with the National Electrical Code, ANSI/NFPA 70,
latest edition, or Canadian Electrical Code, CSA C22.1.
If codes permit and a separate ground wire is used, it is
recommended that a qualified electrical installer determine that
the ground path is adequate.
A copy of the above code standards can be obtained from:
National Fire Protection Association

■ A 120-volt, 60-Hz, AC-only, 15-amp, fused electrical circuit is
required. A time-delay fuse or circuit breaker is also
recommended. It is recommended that a separate circuit
serving only this hood be provided.
■ Do not ground to a gas pipe.
■ Check with a qualified electrician if you are not sure range
hood is properly grounded.
■ Do not have a fuse in the neutral or ground circuit.
■ The range hood must be connected with copper wire only.
■ The range hood should be connected directly to the fused
disconnect (or circuit breaker) box through flexible armored
cable or flexible metallic conduit.
■ Wire sizes must conform to the requirements of the National
Electrical Code, ANSI/NFPA 70, latest edition, or CSA
Standards C22.1-94, Canadian Electrical Code, Part 1 and
C22.2 No. 0-M91, latest edition, and all local codes and
ordinances.
