Wood burning too hot?

[Thechap]

Hello everyone! I am hoping someone can help me out. I have a Harman Mark III Coal and Wood Stove. I am trying to burn White oak but the stuff just burns way too hot! I can close the "air" off and the thing still burns too hot. This is a new stove so I know the gaskets are good. This thing burns coal excellent, but I get the wood for free. I have about four cords of oak cut but just can't use it. Any ideas on how to cool this thing down?

What temps do you mean by hot? Do you have a thermometer?

 

[Thechap]

No thermometer. Trust me, the heat from that wood is nothing compared to the coal heat. I can control the heat from the coal, but when you burn that oak, even two pieces of it, you have to start opening windows!! By the way, would purchase a thermometer if I knew what to buy.

Thanks for your response!!

I've never burned in one, but from what I can see, Harman lists this stove as a coal stove, coal only as fuel. The air intake doesn't appear to be designed for wood burning, it bottom feeds the fire. Does the manual go into wood burning? Corie will likely have greater insight here.

yeah, that thing will probably never burn that seasoned oak. I will stop by and take it away to save you any future trouble ;-)

I never thought about the bottom burn thing. Guess I will have to buy another furnace for the attached garage, and then heat the rooms above the garage!!

Check the local code regs for burning appliances in the garage. Often these are banned.

Just looked in the manual, there is nothing about burning wood in that thing (except to get the coal going). Its a coal stove, period.

It is a coal only heater you may only use wood to help start the fire.

I'm a little unclear on the air intake, bottom feeding the fire thing. My wood furnace claims to be wood/coal furnace. The air intake (wheel) is under the fire grates, where it supplies air under the wood. But in addition, the draft blower fan sits above or same level as wood, depending on how much wood is in the firebox. But I only use the draft fan once in a blue moon. Otherwise its just barely cracked open, using the bottom fed air draft for 90% of combustion air. Am I doing something wrong here? The owners manual for my unit is very basic and pretty much a waste of good paper. Should I slide the adjustable, draft fan, door open more when burning wood and keep the bottom, air draft wheel closed? Or is it a combination of the two to burn correctly. I'm just running the unit like my previous puff dragon. Seems to work so far, but maybe I can do better??

I use the adj slide on the draft fan to control the amount of air going in to my firebox, but my air wheel adjuster is on the
door. My furnace is the Yukon Big jack.

I burn lots of wood on my harman mark III, You door gaskets need to be replaced you are getting too much air . New gaskets every year if you are using it alot.

Purchased an outdoor wood boiler in 2008 and was the best thing I ever did. Plenty of heat and free hot domestic water. Still have the Harmon though and 3/4 ton of coal LOL.
