Thanks everybody for answering my vent question. Now, about running it on low on a regular basis . I figure it would keep the temp at a fairly even displacement but even if it doesn't , i'm still curious as to what harm or effect if any it would have on the stove's inner workings . Talked to a stove manufacturer yesterday and i really thought he was very careful if not evasive with most of my questions . He more or less told me my dealer could answer my questions. This really made me "wiggy" . But on everyone's advice on here, i will be going up & thru my roof overhang .
