Lopi's can run hot, especially for someone that's not used to 'em. It may be an air leak but the only way to tell for sure is to ask him about the fire... is it "roaring" the whole time and going nuclear? Or is it off-gassing and the secondaries are cranking and causing the stove to slowly dip into the "hot zone" ? I'm with woodlands and HDRock... check that gasket and re-read the stove manual for operation tips. I know I'll be putting a pipe damper in for my Liberty in my basement, just for an added control measure. They are great stoves and, unlike low-quality steel stoves, can probably handle the higher stove temps from time to time (cracks in the manifold and warped tubes not withstanding haha).
I've had the Buck up around 700ยบ and that's hot but I have a blower, if not it may climb higher than that. He has to be getting too much air from somewhere I would guess.
They're built like tanks. The rep from Lopi was at our local dealer a year ago when I came in, I talked to him about how the Liberty can burn hot, he said don't worry about the temps, I said what about the warranty, he said we test them at a much higher temp than that, I wish I had his name. They told me anything over 800 is an over fire so that is what I go by.
Just a thought , my republic doesn't have one but ,is the bypass closed up all the way, if so maybe something is out of whack with the bypass , not probable but possible. As a matter of fact I screwed up on my last load today, I had it mostly dialed down but then I wasn't paying attention I looked up and the pipe was sitting at 500, oh chit!! the stove was about 725, shut the air down all the way and turned the blower on full blast, it cooled right down in 5 10 minutes and then I had to, open the air back up because it just about put it out. My stove hit about a 825 one time too when my gasket was screwed up, and it took me a half an hour to cool it down with the blower on full blast and another fan blowing on the side of the stove
Not exact numbere but im guessing 8-10ft inside the house then another 4-6ft outside? His stove does not have an ash drop HDRock , the bypass seems to close all the way as it should. With the intake air control rod pulled out (closed) you can hear the stove sucking air from underneath. Under the stove the intake air holes are still somewhat open even when the rod is in the closed position. It just doesnt seem that you can totally shut the air down on the stove
Is the plate (or whatever it is) covering the holes accessible? If so, would it be possible to put some flat gasket material on it to close up any gaps? I did that with my old stove and it helped a lot.
Don't forget that with the new stoves you can not completely shut the air off. They are designed that way and for the most part, that is good. Ask him if he's read the manual.
