Electrical: A four-wire or three-wire, single-
phase, 240-volt, 60-Hz, AC-only electrical supply is
required on a separate 30-ampere circuit, fused on
both sides of the line. A time-delay fuse or circuit
breaker is recommended. Connected directly to the
fused disconnect (or circuit breaker box) through
flexible, armored or non-metallic sheathed, copper
cable (with ground wire). Flexible armored cable
should connect cooktop directly to the junction
box. A U.L.-listed 1/2" (12.7 mm) conduit
connector must be provided at the junction box.
The recommended minimum copper wire size is
No.-10 gauge. However, wire sizes and
connections must conform to the requirements of
the National Electrical Code and all local codes and
ordinances.
Venting system: Use metal vent only.
Exception: Under a concrete slab, PVC may be
used; see Installation Instructions for details. Rigid
metal vent is recommended. Do not use plastic or
metal foil vent.
This downdraft cooktop is rated at 60 feet
(18.3 m) of straight vent or the equivalent.
If vent length is 10 feet (3 m) or less, 5"
diameter round vent may be used. If vent length is
more than 10 feet (3 m), use 6" diameter round or
3-1/4" x 10" (8.3 x 25.4 cm) rectangular vent.
Venting system must terminate to the outside.
Cooktop location should be away from strong draft
areas, such as windows, doors and strong heating
vents or fans.
All openings in the wall or floor where cooktop is
to be installed must be sealed.
