• Cabinetry over cooktop : 30' minimum clearance
between the top of the cooking surface and the bottom
of an unprotected wood or metal cabinet. 24" minimum
when bottom of wood or metal cabinet is protected by
not less than 1/4" flame retardant millboard covered
with not less than no. 28 MSG sheet steel, 0.015"

Minimum horizontal
clearance between the

the cooking surface is
6" (see solid areas).
• To eliminate the hazard of reaching over heated
surface units, cabinet storage space located above
the surface units should be avoided. If cabinet storage
is to be provided, the hazard can be reduced by
installing a range hood that projects horizontally a
minimum of 5" beyond the bottom of the cabinets.
• Countertop must be supported within 3" of cutout.
Grease container
• Radius corners of cutout and file to insure smooth
edges and prevent corner cracking (1/4" radius).
• Blower can be swiveled 90°.

Unit is rated at a maximum of 60 feet of straight duct, 300CFM of
"make-up" is required. The blower has 2 range settings; Low range
is used when equivalent duct length is up to 30 feet and high range
is used when equivalent duct length is between 31 and 60 feet.
1. Use 6" diameter round or 3 1/4" x 10" rectangular only, except
for equivalent duct lengths of 10 feet or less that vent straight out
the back of the cooktop and directly through the wall. Equivalent
duct lengths of 10 feet or less can use 5" round duct. A transition
from 5" round duct is necessary when connecting to 6" round or
3 1/4" x 10" duct.
2. Do not use 5" elbows except in a 5" system. Instead use a 5" to
6" transition followed by a 6" elbow, or a 5" to 3 1/4" x 10" elbow
transition.
3. Use quality metal duct of at least 26 gauge galvanized or 24 gauge
aluminum. Inferior quality pipe fittings can cause up to twice the
restriction and is a poor value. 6" diameter PVC sewer pipe can be
used for under slab installations. Local codes may require a heavier
gauge material or restrict PVC. Check your local codes.
4. Distance between adjacent fittings (elbows, transitions etc.)
should be at least 18". The farther the better. Closer distance
promotes turbulence which reduces airflow.
5. The number of downstream elbows or transitions should be
limited to three. The initial 5" to 6" straight transition, if used, need
not be counted in this number.
6. Handmade crimps are likely to cause restrictions.
7. If an alternate wall or roof cap is used, be certain duct size is not
reduced, and there is a backdraft damper. It is best to use listed caps
to be certain of proper performance.
8. Thermal breaks: In areas of extreme cold weather, it may be
necessary to provide a short length of nonmetallic duct as close to
the wall as possible, to prevent conduction along the metal duct.
9. High altitude installations: It is advisable to reduce allowable duct
run by 20%.
10. In Canada, the installation must conform with local codes.
11. Elbows, wall caps and other fittings are shown below with their
equivalent straight duct length. Each fitting value must be added to
the amount of straight duct length used, to determine overall straight
duct equivalent length (60 feet maximum).
12. When using flexible duct multiply length of flexible duct by 2.
