Default Re: Advice on bath exhaust vent termination.

The question I have is for the termination of one of the fans. It would be easier for me to cut through my cedar siding to do a side wall termination. It would be about 12 -15 feet total vent length. If I did the roof I would need to hire someone to vent through the roof(About 3 feet)

The fan is a Broan Model 683 CFM 80

Not sure of the maximum length of vent.

For sidewall application.
Would you slope vent up slightly or run on attic floor?
What type duct would you use? Flex, semi corrigated metal?

Also, running them out a sidewall with rigid duct buried in insulation to prevent condensation is good.

The distance run would depend on the size of the bathroom and cfm of fan but, like Jim said, it should be okay.
