You may not need a Barometric damper. If you were able to control the burn rate in your Mark I using just the air vent in the ashpan door, then you probably will be able to do the same with the HItzer.
The idea behind the Baro is that if say, you set the stove where it has been burning really well for a 25* evening, with light winds, and you go to bed. Then a cold front comes through at midnight, the wind picks way up, the temps drop, then the draft in the chimney will go way up. The amount of air pulled through the air vents will increase and the fire will burn hotter and faster. You may not want the fire to be burning hotter and faster. If you feel this scenario may be a problem for you then a Baro damper will even out the draft to a much more consistant level, allowing a more steady heat output and coal burn rate.
Do not install a manual damper, for all the reasons above, a manual damper is manual. The barometric damper is automatic. You can't be there when the manual damper needs to be reset. If the weather warms way up during the day and you are gone, the wind dies, and the draft decreases, a manual damper needs to be opened to increase draft, you won't be there to make this adjustment, and you could get CO in the house... Don't want your dog breathing CO !! A baro will automaticly adjust to give full available draft if the weather warms or the wind dies. And it will automaticly open to reduce draft so you don't burn too much coal if the draft increases.
You will really like the hopper feed feature in your Hitzer. You can control the coal burn rate by shaking more or less. Each time you shake the grate, the ashes fall, the coal level drops and fresh coal is on the fire. If you delay the shake, the fire will have less fresh coal, and a bit more ash under the fire, lowering the heat output some. Member Davemich used to shake only every 24 hours in warm weather, to reduce coal use, he still had plenty of heat output, but he has a smallish house.
Let us know how it goes, that sure is a nice addition to the house !!
We had an automatic air damper installed and glad I did. When the cold front came through this area, so did the winds. I noticed the temps on our stove rising because of the increase "air draft" coming through the stove.
Our air damper was set too tight so I adjusted the weight on the air damper flap. Boy the thing opened right up allowing the excessive air to draw in through the damper rather than my stove. This could get dangerous if your away from your stove.
Once the air damper started to work, my Hitzer settled down to its normal temp settings.
Good safety feature to have installed!!
