Please briefly explain why you feel this question should be reported.
I have a kitchen exhaust question that I hope you can help answer!
We recently purchased a home and it has a ducted range hood (Broan Allure 250 CFM or so model) connected to a duct that goes through the kitchen ceiling through the attic and connects to an exterior exhaust fan mounted through the sidewall of a dormer.
The external fan is wired to the switch on the hood above the stove. The external starts when the hood switch is set to the hi position…and both fans run at the same time.
The external fan motor is: 1/20 HP, HVAC Motor, Shaded Pole, 1550 Nameplate RPM, 115 Voltage, Frame 3.3
This seems like an unusual configuration to me and honestly doesn’t seem to work all that well.
1. Is this a common setup?
2. Would a much higher CFM fan and the exterior fan upstairs work much better?
3. Would you recommend a different configuration?
Any insight would be greatly appreciated!
Thanks so much!
