Install the Ductwork
• Ducting must conform to local code materials and “make-up”
requirements–300 CFM minimum.
• IMPORTANT: Save for local electrical inspector’s use.
• Ducting a cooktop is easy but critical for proper performance.
• After reading these instruction, plan the duct run.
• Use the “Duct Length Chart” to find the equivalent length of the run.
• Shift the blower to “high range” if indicated (done by snapping the
“restricter ring” out of the blower inlet). Be sure blower is not running.
• Install the duct hardware.
IMPORTANT
Total allowance duct system is:
90’ with 6” round wall cap
80’ with 3-1/4” x 10” wall cap
Low range is up to 60’
High range is 61’ to 90’
General Considerations:
1. Use 6” diameter round or 3-1/4” x 10” rectangular only except as follows. For
gas models, 5” diameter round must be used if the straight duct length is
10 feet or less, using a 5” round wall cap.
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 and fittings can cause up to twice the
restriction shown and is a poor value. Local codes may require a heavier
gauge material or restrict PVC.
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 that 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. Follow the duct calculation carefully for best performance and satisfaction.
