Today, I made a trip to a local Fireplace store, and the counter clerk was very "chatty". I originally was asking about Hot Ash vacs, and told him I burned coal, and his 1st reaction was
( kidding tho,) cause he told me yrs ago he had a Chubby and loved it. He was a middle age guy, and "supposibly" has been in the business awhile.
When I mention my baro installation, and performance observations, he told me my damper door weight should be adjusted so the door is in the closed position always, "except" when the wind blows. I told him Surdiac recommended an -.04 draft, and if my door was closed most of the time, my draft is up around -.06-07. He said it shouldn't make that much of a difference. But I know my burns times drop a few hrs when my draft is that high. I agree my stove temp will run higher with a higher draft, but don't want to sacrifice what little burn benefits I'm receiving at this setting. I've experimented with my MPD positions, and whether it's totally closed, or fully open, the baro door doesn't adjust much at all. Any opinions are welcome. Thanx. Below is a pic of where my damper door is usually situated.
