That's a great question. It's 5 inch on the outside. I don't know yet if I can tear the 4" inside tube out and push 4" CAT 3 through it. Maybe someone on here knows if that is doable? I want this to pass code inspection.

Now I'm reading that I have to replace that Type B vent pipe with CAT III. I'll have to cut out the drywall and whatever else is near it and put in the stainless steel pipe that costs quadruple. 400 for the Big Maxx and 400 for the vent kit. Unbelievable. This $500 project is turning into...

Is Cat III required for code? The previous owner of my house put Type B through my garage wall, plumbed with gas and electric, the whole deal. But, he never put the actual unit in. I would really rather not have to tear up the drywall and reinstall CAT III thimble and pipe.

It's only a couple feet and straight right now. I can see that it's clean as can be in there. Once it gets put together, I guess I can run some kind of heat sensor from the outside, is that's what you are suggesting? Here is what it looks like. I didnt take a pic through the pipe, but it's...

I don't know for certain that it is a requirement. Maybe only for new construction? Since its existing, I grandfather in? Except they never actually installed the unit. They did 90% of the work and then quit.

I would like to set it just warm enough to keep it from being frozen in there. I live in the Rockies and it gets sub zero all the time. Lowest I saw this year was -24F, not windchill, just temp. I would like to make it run all the time at like 40-50 degrees, just to keep it warm for the cars and...

I see they ran the electric nearby, but they didn't splice access. So, Ill need an electrician to put in a T or something. Another headscratcher why they didn't just cap off the wires.

It's an attached garage. I'm leaning toward the 80K, hell, it's $35 cheaper on Amazon. But, I also realized that if it's kicking on and off all the time, that's hard on the unit. Might be better to get the 50K, and just leave it on low all the time. Waste of money though. Most of the time...

I bought a house. Its plumbed for gas, electric,thermostat, and exhaust. The preinstalled exhaust is type B double walled. 4 inch inside and 5 outside. I dont know if I should call it 4 or 5 pipe. I read somewhere that stainless steel is now required? Is that correct? I really dont want to...
