Question:
What is the difference between a Class A and a Class M chimney and how could one tell them apart?
Answer:
Class A is an all-fuel chimney, which is good for wood, coal, gas or oil. I have never heard of a "Class M" and though it may exist, it is not commonly used or labeled.
Class B is for gas only. Class L is for Pellet and Oil.
Perhaps "M" is the new direct vent gas pipe.
