Is there anything bad about burning wood in a Mark II? If I was to look at one to purchase, that has burned only wood in it in the past, what sort of things should I be looking for during the inspection?

I plan on burning coal in it.

Thanks for any advise.

Other than a coating of cresote on the glass wood burning should not hurt the MK II. Look inside and check the condition of the baffle over the center of the firebox other than that wood doesn't burn as hot as coal and should have caused no damage to the grates or firebox

Possibly broken fire bricks from jamming chucks of wood into the firebox. This shouldn't be a deal breaker, but could be used to dicker the price down a little. :)

Check to see the glass was properly replaced.
Wood always busts the glass.
Fill with wood, fail to notice crook in the last piece...
slam...
crack!

I plan on burning coal in it but the previous owner only burned wood in it occasionally.
How should the shaker grates look/operate? I have not owned a hand-fed stove before and just want to know what I should be looking for.

Thanks

Grates move freely no contact with other parts.
Lever on left moves the grates.
Air vent in front spins shut.
Ash and loading door should move freely.
Splits, cracks missing baffle are bad

When looking at the grates from left to right, they should not sag in the center. If they do, the stove was overfired and when you burn coal and shake it down, it's much easier to dump you live coal in the ash pan. The grates are replaceable but about 75.00 to 100. bucks.

I have owned the Mark III for 4 years now and have burned wood in it when I ran out of coal and had no problems at all. While wood does burn hot it is no where near the heat of coal. It would take an exceptionly hot fire to warp the grates and that would be rare as they are very beefy. As said above check it out fully before you buy.

I've owned a Mark II for 5 years, it's my 2nd coal stove, been burning since '93. You can burn wood in any coal stove. I burn wood early fall/late spring easier to start for unexpected cold snap or just to take the chill off. Always start my coal with a wood fire. Only once for the long haul, hopefully. Do have to replace the fire brick this year, a little too agressive throwing the chunks in, but the cracks aren't any bigger than the spaces between bricks, so OK. Clean the chimney about every 3 years, but I only burn maple/oak, maybe a little elm that fell in, never pine except kindling scraps.

I love my Mark II, she kept me warm all winter (mine's a she). :D

Should say you can burn wood in any hand fired coal stove. Can't burn it in a stoker.
