Appalacian 52 bad burn times

9.9 times out of ten the advice will lead to your firewood not being dry enough. What type of wood is it and how long has it been cut, split and seasoning?

What type of wood is it? And also check to make sure you ash pan door is fully closed.

My woodstove is a Appalachian 52 Bay and I have had mine for 2 years now. I get good overnight burns. Just takes alittle time to learn how to operate it. The burn times depends on the condition and types of wood. I can get good useable overnight heat with mine. Load the stove at 9pm and have good coal bed at 6 in the morning to start over again. As the other have mentioned, the seasoned wood it the main thing to long burn times.

Oak will take at least two to three years to season properly depending on size of splits.

I would be checking the ash pan dump too. I have a buck model 80 which I think is similar to your stove that was leaking around the ash dump. shoot, my englander 13 was the same way. both stove got a dose of furnace cement around the ash dump. Its easier to just scoop the ash from the stove anyway.

I am sure you have already read my review on the bay 52, seal that ash dump and you will see longer burns.

Oak split in March 2013 covered or not, is no where near ready to burn. That wood should be put away for 2015/2016 burning season.
That said, the burn times should not be short or blazing away with wet wood.
There must be an air leak somewhere on the stove, unless you are running it with the air wide open in an effort to burn the wet wood.
Something is not adding up here.

According to the manual I saw, that is a cat stove. Does it have the cat in it? If not, there is a big part of your problem.

I have been learning to burn in a new 52 Bay since October and burn time is NOT one of my problems. With good wood I have been getting 8 hours of decent heat with draft control about 30% open. In October I was able to get nearly 12 hour burn time with draft just barely open but the heat output wasn't suitable for cold winter weather.
