What is the recommended draft requirement?
...300 degree stack temp seems high to me...
on the coldest of days and running flat out...ive yet to get stack temps much over 250 degrees...
...its a much larger unit (furnace) tho..
i believe the recommended (over fire) draft is - .02 (for my unit)

Keystoker says .02 for a draft. I cannot get it any lower than that, the baro is maxed out. And I still have no idea why my stack temp is so high. Anyone have any suggestions?

.02 sounds pretty low to me, something fishy there. A six inch chimney liner doesn't sound Kosher either. The chimney generally should have a larger area than the breach/stovepipe.

Keep in mind, overfire and stovepipe draft will not be the same number more than likely.

...true- .0 2 is my over fire reading...
I am curious if your baro opens when the stove is in normal operation

What do you feel draft draft should be? Do you guys think chimney size is playing the factor?

i would think that -.04 to -.06 would be ok...
...but if ut overdrafting...maybe cut down combustion air or checkk gaskets?
...if anything...ur chimney is on the 'short' side height wise (imo)

gitrdone, As you would slowly close comb. fan flap you will then see mano. reading increase...this is how to raise draft to higher number...do opposite to get lower reading.

I have a direct vent straight out the wall at .03 draft average, never touched the factory set fan plate or the push bar screw. I have a draft gauge hooked up at all times. When the draft drops to .02, I know it's time to clean out my pipes and the exhaust blower blades.

I have never taken any temperature readings. I just set my coaltrol at 71 degrees and the home is stable at that temperature.
By the way, I have to agree with Rigar, 300 sounds high for the stack temp. At work, our building (125K sq. ft.) boilers (2.5M btu/hr) have those numbers for the stack temperature.
Anyway, I'll try to get some readings for you next chance I get.

So I'm still kinda lost as to why my stack temp is so high

Sorry for the delay. I took some readings with a IR thermometer. Calling for heat, the front of the stove read 450 degrees, the direct vent pipe read 160 degrees, the supply duct reads 175 degrees and my DHW is at 125 degrees.

Have you confirmed the thermometer you are using is accurate?
