Low to Mid Efficiency Furnace Vent

Can someone tell me if this venting is properly installed and should anything be called out.


What is your concern? I cannot really tell much, post overall/zoomed out pics. Based on the transition size/hood, I am assuming it’s gas-fired?

Yes it’s gas fired. I’m talking about the size change in vent and sealed properly at furnace?

Hey Mike,

From the pics, it looks good. You’re allowed to go from smaller to larger, but not the other way around.

Good luck,
