Damper gets stuck closed
How can I fix the damper so it will open when the fan is turned on. This unit is 5 years old and runs very well. However, this week I noticed the damper won't open. I have to open the window and pull it open.
The damper on my fan would stick to the weather seal also. Try this. This isn`t easy, but I held open the damper, and I applied caranuba car wax to the damper and rubber seal it touches when closed. It has worked great. Spaying silicne on it did not work as well.

508 duct vent into Attic?
We purchased the 508 direct vent over a years ago for another applicaiton that we chose not to move forward with. Today, we are rennovating our 3rd floor apartment and would like to use this vent with duct connection to an attic vent. Is this possible?
I live it Marietta,Ga mine is vented in and unfished attic which is ok according to our local building codes. I suggest you check with your local building inspector or code inforcement dept.

What size hole?
The instructions say cut a 6.375" hole thru the outside wall for installation. What size hole do we cut on the inside wall?
Thank you for your question on the model 512M through the wall exhaust fan. The 512M can be installed in outside walls up to 10 inches thick. Walls less than 6 inches thick will not use the adjustable duct. If you are using the adjustable duct, cut a 6-3/8 inch diameter opening in the inside wall. If you are not using the adjustable duct, cut a 6-1/8 inch diameter opening in the inside wall.
