Hello! I have been reading these forums for a week now trying to get all the information that I need to purchase a new pellet stove. I just ordered three tons of pellets yesterday but don't even have a stove yet! The stove will be going into my living room and venting on and outside wall. I was told by three different dealers that if they add the outside vent kit that I only need an 18" clearance from the front door (we don't use the door but it is a door that "can" open). Today I called one more dealer to inquire about another stove and they told me that I need 48" clearance from a door or a window. I told him that the other stoves I was looking at only required the 18". He said he would read up on it and call me back. He called back and said we definitely need 48". The stove is a Napolean the model number is NPS40. Does anyone know where I can find the information regarding the 18" clearance on this stove? So here are the stoves I have narrowed it down to. Any pros and cons on these would be greatly appreciated. Greenlife Pellet Stove by Regency model GF55 45,000 BUT 55 lb hopper. Total installation including everything would be $3400.00 St. Croix Afton Bay 40,000 BTU (this is the floor model). Total installation including everything would be $3400.00 Napolean NPS540 40,000 BTU total installation including everything would be $2979.00 (but this is only if I can find them the information on the 18" clearance because he doesn't seem to know what I am talking about). Thanks so much for any help anyone can give me. I am doing all of the research on this as my husband would just buy the first one he saw without doing the leg work!
