Hello Huys,
I have the little 1 CFT CFM-FW240007 stove.
I decided to load two logs in the stove a once. In a matter of minutes the temperature was reaching 900 F that was with the air intake closed at the maximum.
My question is: How do I load the stove with the maximum load of wood without reaching these insane temperature?
Thanks for the help,
Damien
 
There must be more to the story than this. Loading 2 logs to what? Was the stove filled with 6 inches of red hot coals?
 
two logs of white oak. yes they were coals but do not believe it was 6 inches. I am guess between i and 3 inches of coals
 
What was the temps before you put in the 2 logs?
 
The temperature before I put in the logs was around 300F
 
And were are you taking your temp. from? inside the stove should be 1100 and up, but if this is from the outside of the stack you may have chimney fire.
 
I can imagine that very small stoves like that could be more difficult to manage. When you put a full load of wood on a bed of hot coals, that wood is going to off gas quickly and the temps can zoom. You'll probably have to let the coals burn down a lot more before adding that much wood. Or add a smaller amount.
 
the temperatures are from above the stove.
 
Sprinter: So to summarize I have to let coal die down some more before reloading the stove. I will try that tomorrow.
How much coals should I leave in the stove before I reload? Any suggestions are welcome

Can you be more specific? Are the temps taken on the stove top or the flue pipe? Approximately how large were the oak splits?

Definitely let the coal be die down some more before reloading. Open up the air to accelerate this phase.

What I would try is allow the coals to burn down until there are just enough coals to start a new fire. Then you can experiment from there. If you're in a hurry, open the air up to burn the coals down quicker.
 
I have that stove in my shop. I have a magnetic thermo just above the flue collar on single-wall pipe. I have never, no matter how I've operated it, seen a temp higher than about 625°F at that location. More typically it runs 400°F - 500°F. Rick

Begreen: the temperature was taken on the stove top and the coals are between 1 and 2 inches

Rick, are there any particular tricks or tips to operating that size stove?
 
That is a good question Sprinter thanks for asking it

I can't really think of any significant differences in the way I operate the little Century as compared with the way I operate my big Liberty. No tricks up my sleeve. Load it, light it, adjust the air as needed, walk away. Check it periodically and give it whatever it needs.
 
Is this a new issue? If the air control closed won't eventually slow the burn, it sounds like you have an air leek somewhere.
 
Xman23: You may be right. The question is how do I find it.
 
The key word in xman23's reply is "eventually." I find with my small insert that reloading on 2" of very hot coals will often produce a temperature spike. When I close down the air the temp goes even higher as the secondaries flame very energetically, but "eventually" (2-3 minutes) it calms down.

Good idea Sprinter
 
I don't know the stove, fossil may be able to help with where hidden air leaks could be. Of course the door gaskets and look for cracks inside and out.
 
Damien, how tall is your flue from stove top to cap? Just to determine if too much draft could be a problem.
 
The flew from the stove to cap is around 18 feet.
