Are the big maxx heaters power exhaust vented?
Holy ****! Power vented unit would eliminate that right? I installed a 400k Reznor unit at work and it uses a piece of pipe, a thimble, and a cap straight out the wall.and the vent kit for $300.
the horizontal kits now need to be stainless, thus the cost.
Because that is required by code. But if you don’t care about code, you can use B vent. Until the code changed, it was allowed.
