I've just upgraded from a Royal Guardian to a Blaze King Princess, and in doing so I had to conform to the wifes request to move the stove laterally to gain space back in the dining room. The lateral move is a total of 49" from center of the pipe to the center of the new pipe. I am having a local company install the new stove and when the showed up to install they said the the stove pipe along with the stove had to have a Hearth. Can anyone steer me to a regulation that stipulates this? I live in North Pole, Alaska (out of city limits, If that matters).
