The standard 350 c.f.m. exhaust fan, included in the upper cabinet of your range, is factory-set to recirculate air through a charcoal filter. It can also be used to outside-vent exhaust if there is not more than one 90-degree elbow or more than ten feet between the range and the outside wall. This fan exhausts air only from the back of the range cabinet – it cannot be adapted for top-venting.
The optional in-line exhaust blower replaces the standard 350 c.f.m. exhaust fan provided in your range cabinet and is to be installed by your contractor where your exhaust ducting exits the house. The inline blower should be ordered when you purchase your range – the range and wiring must be modified to accommodate the blower. (The blower can be shipped in advance of the range for installation – additional shipping charges will apply.)
If you are outside-venting your range with more than 10 feet of ducting, or more than one elbow… or if you simply prefer a more powerful exhaust system … you should include the optional 520 c.f.m. in-line exhaust blower. The #1518 In-Line Blower exhausts smoke and cooking odors quickly and quietly, exiting the house up to 35 feet from the range. If desired, the blower can be mounted in the basement or attic for powerful, whisper-quiet operation.
