Baro damper question

Baro damper question

PostBy: gambler On: Mon Oct 29, 2007 4:10 pm

I just installed my manometer today so that I can keep an eye on the draft. My question is this, awhile back I posted in the Leisure line section and asked Jerry what the baro should be set at for a leisure Line stove and he replied .02 at low fire and .05 at hi fire. Well today after I istalled my manometer the ouside temp is 52* and the stove is at idle and has been for a couple of hours but my manometer is reading .04 with the baro set as low as it will go. Will this become a problem when the weather gets colder? I am using a prefab chimney so I can shorten it if need be.
Looking for advice from the experts!

The baro will only function at its set limit. In other words, if it is set at .05, it will begin to open to keep the draft from rising above that. Below its setpoint it will remain closed. It will not increase, decrease or affect your draft other than making the setpoint the most draft it can have, a limiter if you will. If you want to reduce the .04 draft lower, take the weight knob off and try a nut and washers until you get the weight you need for the draft you want. Be sure to confirm your draft readings. If your lucky, that weight can be slide to near the far end to reset the baro for high fire at .04. Don't shorten the chimney.

Now that I finally had a good fire I think My baro damper is working right.

The question is though that it is always open pretty much wide open when ever there is a fire.It dosent matter much if it's cranking along or barely burning .
I think if you have a chimney with very good draft the above would be true is that correct ???
I have a dwyer gauge and it is set to .03 and it holds there under somewhat of a fire and drops when the fire is not that hot but the damper stays open.

Thanks for your insight

I'm going to have to study the Dwyers a little more as they are lower in Range than what we use here at work.

Yes, .03 is pretty a pretty low setting, with a very good chimney it will be working almost all the time.

Outside it is warm during the day and cold at night.
I have the air valves cracked open (all 4) a little more or less than a postage stamp. The stove is keeping it around 74 in the lower protion of the house to 77 depending on the fill while holding 68 to 70 upstairs. A magnetic thermometer stuck on the pipe about 18 inches from the stove says 250 when the stove is HOT and 200 when the fire is settled down (comfortable). I'll still put a baro on it hopefully this weekend.
My house will get colder when it gets colder outside and windy but for now the coal stove is doing an awesome job!
