I just dropped off a Woodstock Fireview at my brothers house. He has never owned a woodstove as where I have owned over a dozen, but, he knows more about woodstoves as he has indicated to me. Anyway, he has measured in great detail where his hearth at the front will end in his room. A couple maybe 3 inches from the front of the stove (non front loading). In the manual it has a plan view clearly stating 8 inches. He said that the 8 inches is diagonally, in other words taking into account the height, so it's 8 inches from the lip then down to the hearth edge rather than straight out. Is this correct?
