4 Questions from the Community

What is the clearance to combustible materials?

The Metalbest 6UT-48 requires a 2" clearance to combustibles.

Is the 6" the inner diameter or the outer diameter? Maybe a better way to ask the question is: What is the inner and our diameter of this chimney pipe?

The Metalbest 6UT-48 has a 6" inner diameter. All venting pipe is measured by inner diameter to try and eliminate confusion.

Does this pipe stay cool on the outside?

The Metalbest 6UT-48 will not be cool to the touch as it is only a double wall pipe. If you would like it cool to the touch I recommend triple wall.

is this pipe an all fuel product

The Metalbest 6UT-48 will work for wood, oil, coal and gas. It isn't suited for a pellet stove however.
