Exhaust pipe

[Reg1952]

I have a tube heater in my shop and the elbows on the exhaust end are getting rusty. Will need to replace soon but I dont know what to ask for. I dont think their just galvinized 4 inch elbows.

Mine rusted too, they are just normal stove pipe galvanized on mine. I noticed mine got rusty the first Winter but have not gotten worse....how long have you had yours?

 

[Reg1952]

Its been up for 7 years.

Some of those look ok.......until look and feel up close..........to find they are paper thin and crumpled when touched.

It’s also the reason horizontal venting of the hanging furnaces switched to CAT III stainless vent pipe.

No idea if B vent and galv stove pipe is still code or allowed for horizontal radiant vent.

B Vent is the pipe they have under the tube heaters at Menards.
