I think since you are having a draft problem, maybe you should try closing off the combustion fans opening a bit. I would use blk electrical tape (easy to remove and add). Also, I'm sorry about you not getting a coal-trol with the stove. The only difference in your model and today's model is the coal-trol. I don't know what the dealers have on their floor so I can't say how new or old it is. I can tell you that there have been very few changes (other then the coal-trol) to the units in the past 5 yrs. If you decide to move the PV, make sure you have the clearances from windows and door openings.
