How to clean a Magnolia stove?

Are you referring to cleaning the flue, or cleaning out the firebox/inside of the stove?

So the baffle is not removable at all?

Many stoves today simply use a ceramic board that rests on top of the secondary air tubes. You usually just remove the retaining pins from the tubes, slide them out, then pull out the baffle (carefully). Make note of the order of the burn tubes, as it does matter on some stoves.

Sorry, I was speaking in general. Does the owner's manual give any guidance or list a support number to call?

If you could get a look at one of the new ones in Lowes or whatever, you could probably tell easily, I would give it a try and see if there's a similar one there. It's creosote buildup in there? I don't have suggestions on getting it out, but I am positive that somebody here would!

I'mmmmmm Baaaack hehehe.
I have that stove. The baffle is welded in. Heavy gauge steel and should last as long as the rest of the stove. Cleaning should just be a good hot fire and then maybe a blowgun sometime later when there is no fire.

I have a Magnolia Stove.
The burn tubes are really a solid stamped plate that is welded permanently into the stove.
You can push up the 2 upper rear bricks and have some access. But the feed to the burn tube plate blocks the direct access to the flue pipe. There are 2 steel wedge strips that hold the bricks tight. It is tricky to get them in place from inside od the stove. My stove pipe can slide up into the doublewall that goes through the attic / roof. So once a year I just slide up the pipe and remove the sections. Then clean everything.
