I want to mount the unit on roof and duct to a ceiling defuser inside. I don,t want another fan at the ceiling but I want something like the 504-A without the motor.
Thank you for your question on the model 336 exterior mounted exhaust fan. We do not have a separate ceiling grille to attach to a 10 inch diameter duct.

Is the blower position adjustable?
I heard big noise after I finished 336 installation and turned on the power. I inspected the blower and found the blower touched the back side duct edge ring. If i can low blower a little bit, the issue will be solved. Is the blower position adjustable?
Thank you for your question on the model 336 exterior mounted exhaust fan. The blower assembly is not adjustable. If the blower is tightly secured and is rubbing or hitting part of the housing, something probably was bent in shipping or installation. Please contact the Technical Service Department at 800-637-1453 if you need further assistance.

Would this work with duct that has 3 90 degree turns, approx 8 foot total run?
Range is on interior wall, straight right is blocked by chimney for furnace and hot water heater. Wondering if I can jog duct around the chimney. Thank you.
Thank you for your question on the model 336 exterior mounted exhaust fan. Using ten inch rigid duct work the 336 can handle nine feet of straight duct work without losing any CFM. In the installation you are proposing you will definitely lose CFM. Please contact the Technical Service Department at 800-637-1453 if you need further assistance.

What is the required clearance below a wall mounted fan?
If this was installed low on an exterior wall, what are the minimum clearances to the grade below the exhaust point?
Thank you for your question on the model 336 external blower. If wall-mounted, this should be at least 18" to 24" above the ground. If you have further questions, please contact Technical Support directly at 800-637-1453.
