I'm considering installing a C350 Winterport in my existing masonry fireplace. I know from reading other threads that there are strong opinions on both sides of the OAK issue, so I don't want to rehash that. I simply want to know if the Winterport has a method for supplying outside combustion air. The manual that Jotul has online doesn't make any reference to it, but the exploded parts diagram seems to indicate that there may be one.
Thanks in advance.
