On the ducted projects, we use flex for the branch runs to the supply boxes. We keep those flex runs short - on the order of 5 to 15 feet. It is critical to remove the flex from its box, extend it to its full length of 25', and .

I have been doing some work in a newer development where all of the hvac equipment and duct work is in the attic. Whoever did the ductwork used triangle duct boxes. They used 10 inch supllies off of the plenum of the furnace to these duct boxes located through the attic. Then off of those boxes they have 3, 6 inch flex ducts going to the supply ducts.

There is a 6in flex duct coming off main plenum which feeds a junction box made of plenum board also. Off that box is a 5in supply for each of the two bedrooms and one 4in supply for bathroom. .

Does a junction box on a top plate, behind a flexible HVAC duct, go against 314.29 and 110.34?? We have a ceiling inspection tomorrow, and there is a junction box installed behind an AC duct that is flexible. Should this box be moved before it's too late? It can easily be flipped around to face the hallway, instead of inside the room that it . The duct board consists of a rigid material, and fibrous material can erode into the airstream. Although the duct board can be bought with a treated surface that resists erosion, it’ll be harder to fabricate and will cost .

my main concern is electrical wires and a junction box touching the flex duct for the forced air heat. Save Share Reply . or using a running board are examples of POSSIBLE acceptable alternatives - check local electrical and building codes. J.V., does your answer also apply to uninsulated round or rectangular ducts? . Metal ducts - properly insulated will last but cost more than duct board, and flex duct may cost less than the other two, but they would have to use some duct board at the unit plenum-(the duct that connects to the indoor unit). . failed to crimp them tightly enough to junction boxes and failed to use proper sealing methods.

The Flex must use a significantly different board than the Milan. I noticed too that it was two boards soldered together, but the high beam relay was mounted to the top of the upper board. Nothing accessible besides those few relays , which is why I opted to cut the top off instead of trying to properly desolder from underneath.
