Duct bracing to stop flexing
The main return air duct mounted next to my upflow furnace flexes inward
when the furnace is operating. After the blower shuts off, the sheet metal pops back out (oil canning) with an annoying bang sound. It looks like a brace was created by the installer halfway up. It needs another brace or bracket between this brace and the humidifier above it so the sheet metal can't flex. Where can I find such a brace? Is something ready made for this purpose? |

I use light weight angle iron. -- Joseph Meehan Dia duit |

If I were a heating pro, I guess I would use what was most convenient and what I had in the truck . Me I work with what I have in my garage. I guess I should have been a little more clear. Us what works and what you have to stiffen it. -- Christopher A. Young You can't shout down a troll. You have to starve them. . "Joseph Meehan" wrote in message .. .
