Hey all, redoing the bathroom and I have an issue where a vent fan is really close to a ceiling jbox if I use and elbow ( which is a no no per instructions) if I use a straight pipe, the duct will rest on the jbox.
What are the rules for distance? I could move the fan a few inches if I have to , but have it all rigged up already so would like to get a ruling before redoing the work. The run is about three feet long to the soffit and the fan is 110cfm so it should be able to over come the resistance from the angles. ,
