MSG - way to take the initiative in directly contacting the manufacturers! Tom- this is DIRECTLY opposed to what you have stated. Someone on one side of this debate is ill-informed. Let's find out who! Are there really "many documented cases involving house fires due to out side air kits backdrafting" as stated directly from the tech at Jotul? How are we going to locate these documented cases? Are they just urban ledgend? Has the Canadian government also been duped somehow (their "residential guide to wood burning" document that I previously linked to in this thread says "The same research shows that wind effects around the house can reverse the flow in these ducts, which may create a fire hazard if the duct is connected directly to the combustion chamber"). And what about Jotul's comments that "the scientific data done by the R&D department shows that there is little to no improvement on overall efficiency or performance" which is also basically what is stated in the Canadian document. I think the Jotul guy had a great answer for why all the stoves have the OA adapters and kits - politicians basically FORCED them into it! And in all fairness, I'm sure the politicians thought they were doing the right thing but at least if you believe these references to research and documented problems, it turns out to not be such a good idea. I know we are going to get to the bottom of this!
