At what length should you increase the size of the duct? My duct will be about a 15 foot length. Should I increase from the 4 inch specified?
Thank you for your question regarding the duct run length for the 605RP. The 605RP can be vented 30 feet when using 4 inch rigid duct work. If you use flexible duct, that length will be decreased. Also, any turns in the duct work will reduce the overall length of run. If you need any further assistance, please call Technical Support at 1-888-336-6151.
