What is the best way to set the draft using the manometer? My research on the forum goes from setting it with a full fire to setting it while at idle. I have my barometric damper set at about #3 as suggested by Jerry (previous LL owner).

I would appreciate a quick rundown of the correct use of the manometer in setting a good draft, thank you.

I have my damper at 2.5 on my pioneer but everyone is different. Set the coal-trol to max temp 92*/max feed-rate 99 let the stove run for awhile I did mine for an hour or so and than set your damper so the Manometer is reading .04... If im wrong someone correct me.. My draft on the Manometer never goes past .04 this way it usually runs around .03 with the coal-trol set at 73*..

Agree with the baro set of .04. I read mine 12" above a top venting Pocono.

A manometer reading of -03 to -.04"WC at the breach or some where between the stove and baro is desired. As far as running the stove at max or min fire you should check the draft at both max and min settings to make sure you have enough draft when the heat output is at it's lowest setting and also verify you do not have too much at the high setting. I have seen issues with some chimneys that required an increase in the min setting to assure enough draft.

Some quick tips:

* Use a type RC or M Barometric damper with a scale to see where the draft is set
* Level the pins on the barometric damper to make sure the operation will be as accurate as possible
* Make sure you have the baro weight on the correct scale for your installation (vertical Vs Horizontal)
* Check the draft and adjust your weight to be accurate at both max and min fire if you plan to remove the manometer after checking the settings.

I hope this helps answer your questions.

I also have a little secret to leak out, we are working on a deal with Dwyer to include a draft gauge with every new stove sold after February 1st 2010. We will make these draft gauges available to all LL owners (and anyone else who wants to visit their friendly LL dealer) for a price yet to be determined.

Congratulations to all of you who chose to measure their draft, that is the best way to achieve maximum stove efficiency and assure safe operation. :)
