Recently got a Pleasant Hearth WSL-1800-B woodstove. It seemed to be working properly for the first couple days. Now the flue damper seems to be jammed at least in partial open position. But even when getting control to move, it effects no change and I'm burning through too much wood. While cleaning out ash, I found a broken piece (approx 3 1/2" X 3" with a step) of firebrick thinner than brick lining the box. When moving it into the house it was necessary to turn the stove on its side... Some bricks became dislocated and were put back into place. I don't know where the broken piece came from and can't find diagrams to be able to find and fix the issue. Any help would be appreciated.

I have the Pleasant Hearth WSL 1800 medium stove and the primary air control at the top right of stove will not close all the way.
Not sure if its designed to operate that way or not. It opens all the way but when closed it leaves about a 1/4" gap so it remains open. Let me know if your stilll having trouble with yours and if you have found a fix. I was told that there is no adjustment for it.

That's how it's supposed to work
 
Oh, I do not like the manual they sell with this stove. Well Thank you bholler. Do you by chance own a Pleasant Hearth stove ?
Nope. But all modern stoves have a minimum air setting on them like that

Right, and some are even sneakier where you think and it feels like you have fully closed the control but there is another hole somewhere letting a fixed amount of air into the fire to keep it burning hot enough to not pollute.

you know, I took the ash pan out and looked underneath and I'll be darned there was a small hole drilled out at the bottom under where the primary air tube is located.
Thanks again all. What a great site this is !

With the cold and high wind its change my draft and new epa stove eating wood.....even with a pipe damper closed the best I can get is .08 but I half to make more trips to basement to open damper to make sure flue stays warm and hot so my chimney stays clean.

My draft seems to be very good here. Chimney height is 21' and is a outside chimney. Triple wall insulated 6" dia.
Im still learning to burn tho. Only been doing this for about a month. Im going to try an all nighter soon. Storm heading this way now so may try tonight. I love all the informayion I am getting from so many veterans of wood burning !
Thank you !

That 1/2" hole and 90 degree tube above it is always open and directs combustion air at the base of your fire.
The primary air intake is above the glass and can be closed aprox 75%.

The insulating panel above the 4 secondary burn tubes looks alot like the fire brick that lines the fire box but is a much lighter material. Next time your fire is completely out look up at the secondary tubes and turn the chimney damper open and closed. The piece you found might be broke off that insulating panel/damper. It could be you are not fully closing the chimney if a piece is broken off.
