Recently, i have had lots of inquries about outside air kits, i know this has been discussed before, but i thought i would rekindle the discussion. Its my view, that they can be dangerous, expecially in a situation of a poor drafting chimney. I have had customers tell me that they have had smoke and sparks flying out the side of there house. Reverse draw presents a problem with the perfect "storm" exists. ie; super cold chimney, poor desingned chimney, windy conditions, and a new fire. I read sometime back in Hearth and Home that the industry was shying away from them, and the only reason they exist is so they dont miss the mobile home market, which the federal governmet required outside air kits on all stoves. So my questions to dealers and homeowners... dealers, do you sell them and reccomend them? Homeowners, do you have one installed and what do you think it has done to improve performance? Do you think its a valid point that it makes a stove less efficient pulling freezing outside air and having to warm it to combustion temps?
