Direct Vent w/ Rheostat & Draft Settings

I am about to install a Rheostat on my direct vent Alaska Chaning 3 with a Barometric Damper. I need help setting up the rheostat to get the most out of my stove. I think I read that I want a .05 draft and I have a Manometer. Once I set the draft and rheostat is it constant no matter how high the fire or how low or will I constantly be setting the draft and rheostat each time I change the feed rate? Thanks in advance.

I would set it at MAX Burn rate to make sure it can handle the extra combustion fumes. Then check it when it is idling. It shouldn't change that much. It may drop down a bit when it goes into idle, as long you don't go below .02-.03. You shouldn't have to mess too much with it.

On my feed rate I have 1-5 and I've never run the stove passed 3 so should I use 3 as the max?

If 3 is the max you run it then 3 is fine. As Dave said you just want to make sure it can handle the max it will run at. I only change the settings on my PV when I run at low feed rates due to spring or fall weather. That way when the stove is feeding at very low rates (mostly running on min feed rate)I won't lose as much heat out the PV.

Overall though the PV will be set and forget for the rest of the winter. One thing does happen to mine though, as it gets more fly ash and the oil in the motor is being used up in the PV I have to increase the setting slightly, so just keep an eye on it. After I blow out the fly ash and lube the motor I have to decrease the setting quite a bit.
