But where is 'common sense and prudence' when you are asleep, the wife and kids asleep, and the MPD is still mostly closed from when you last set it,, just before your last two beers, then you went to bed..
If the stove was really hot, with a fresh load of fuel, and you turned the manual damper way down to control it, then when the fire calmed down, but you were asleep and not there to open it back up... then you have an unsafe situation where the manual damper is restricting the heat flow up the pipe, resulting in a cool chimney, less draft, and a potentially unsafe condition...
If monitored all the time, yes a manual damper has it's purpose, but it is just that: MANUAL.. Not everyone is in tune with their stove, house, the weather... a baro damper is, that is why it was invented and put in use... it is automatic. It takes the human's fail-ability out of the safety equation.
Hey, I have a manual damper on 'Big Bertha' And I use it... but it is outside in an outdoor building, with no occupants except a few field mice... So it can't kill anyone.. I'd never use a manual damper in my residence..
too risky... I have those last two 'beers' too often, then don't have a care in the world for several hours... I don't want those several hours to become eternity.
Manual dampers have their place, mainly to control the flow through a leaky old style stove in a leaky old house with a very strong drafting chimney, and monitored by someone with experience, expertice and doesn't set it wrong before those last few 'beers' and bedtime.
A baro does all the above automaticly... HEY maybe the baro was secretly invented by the booze and beer industry so that people could drink with abandon and live to do it again.
