We are still struggling with our VC Defiant's horizontal mode, the details were discussed in this thread:
https://www.hearth.com/talk/threads/51794/
After trying every which way, the horizontal is still inconsistent at best, and works about 20% of time with no apparent change of other variables. We are now thinking maybe our flue/chimney height is the problem. The flue goes straight up through the roof and floor to ceiling is 9' (this includes the stove which is 32" high itself). There are 3 more feet on top of the roof, for a combined height of 12' (I don't know how much thickness there is between the ceiling and the roof, but I am sure it's negligible), which I understand is very marginal to below requirement. On the other hand, the chimney APPEARS to draft fine and I don't really have any smoke problems.
Should we spring for a chimney extension? And if so, how many feet in addition, and how much will it cost (ball-park number)?
