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 is the maximum temperature this fan can be operated in?
I want to use this to ventilate a hot garage - the garage can get to over 110 degrees F.
Thank you for your question on the model 12C through the wall exhaust fan. We do not have an actual temperature range for this unit, but you should see no problem with the temperatures you are referring to. Please contact our Technical Support department at 800-637-1453 with further questions.

Which exhaust fan should I purchase the model 508 or the model 12C
My sunroom is approximately 11 X 20 with 10' ceilings. Being a smoker, I want a fan that is large enough to remove all smoke but is still quiet. I have reviewed the Broan model 508 (270 CFM through-the-wall exhaust fan) and the Broan model 12C (motordor 360 CFM wall exhaust fan). Which fan will be the best choice for my application?
Thank you for your question on the model 508 and 12C through the wall exhaust fans. For your sunroom, the better product would be the 12C. Neither one of these units would be quiet, but the 508 would be slightly undersized for the room. Please contact the Technical Service Department at 800-637-1453 if you need further assistance.
