Well I just returned from my local Lowes store and struck up a conversation with the "hearth associate". Boy what a mistake that was!! They sell Englander pellet stoves. I told him I was having my vent run straight up through my roof, because we often lose power and I wanted a good length of run to avoid smoke in the house. He told me that running the vent through my roof was illegal because on Englander stoves you can have no more than 12 feet of vent run. I said "oh really" and how do you know that and he replied " I just attended a 15 hour seminar on pellet stoves so I know what I am talking about". I told him he should have taken notes because you are wrong!! That didn't go over well!! I replied that if you exceed 15ft. in run length you can go to a 4in. pellet pipe instead of a 3in. He said they don't even make a through the roof kit for a pellet stove. i again replied"oh really" and they told you that at the seminar too?? He said that pellet stoves are only for heating basements and garages because I have one in my basement with an 8ft. run and they said he is "pushing it". I asked him what about inserts for a masonary chimney that the liner exceeds 12ft.--he says you need to buy an auxillary blower to put in your damper to exhaust smoke or" you will die from carbon monoxide". At that point I had to leave I couldn't listen anymore. With people like this how does Englander expect to sell their stoves, with a salesman who is giving people WRONG IINFORMATION!! I own an Englander pellet stove and I am very happy so far...even though my install is ILLEGAL!!
