Okay, but what should I aim for with the temp gauge on the front of the stove?

Gina,
Keep in mind that changes in temp and fire are a lot slower with coal than with wood. Make minor adjustments to the air flow, and walk away from the stove, but WITH A TIMER to remind you to go back to see how it's doing. I use my phone's count down timer for the purpose, usually set to 10 or 15 minutes. Doing that you will avoid seeing 900 again! I'm not familiar with your stove, but mine is a multi fuel too (just coal for me), and I can run it steadily at any temp between 250 and 550 with great results. I suspect your's will do the same. Congrats on finding the best coal stove accessory you can have...this forum!

Whatever makes your house warm enough. But as Franco said, 6 to seven hundred max.
There's no magic number that is just right. I adjust my stove to anywhere from 150 to 600 depending how much heat I need.

Yes, 900 is too hot - did anyone mention the fastest way to cool down a coal fire is to add more coal. It sounds counter intuitive but it's true. You may want to keep a bag of baking soda near the stove, too, just in case you need to put the fire out quickly. Take care, Lisa

Gina...not sure if it's been mentioned, but worth mentioning again. CO detector or two to keep you and yours safe!

Thanks, again, everyone. I have two CO2 detectors, so I'm good on that -- and lots of baking soda! The fire went all night, so I think I'm getting the hang of it and figuring out how to get the temp I want. It's cold enough here that I need it to be around 500. It was down to 300 this morning though and my backup furnace went on. Turned that off when I got up and tried to get the coals going again. I think I shook things too much though as it just fizzled out. We'll see how it goes today. . .

Glad you're getting the hang of it. Coal stoves can be a bit frustrating to get them working consistently, but, in the end, the warmth and low cost is well worth it!

From the look of your grates (in the other thread) your biggest aggravation will be having them plugged up with ash. When that happens the stove temperature drops off like you are seeing. Review Franco's advice in your previous thread about keeping them clear. Glad to hear you are making progress.

By the way, it is CO detectors you have (I hope), not CO2. Carbon monoxide vs. carbon dioxide. CO2 can kill you, just not as efficiently or as dead as CO. :o

Yes, my mistake on the CO. You are correct.

If you need 500 degrees in the very cold, you might have to go to more frequent tending times.

The aim should be to still have close to one half of burning coal still available to ignite the new coal load quickly.

If a stove holds 40 pounds, then loading 20 pounds at each tending would be best for a 12 hour burn and still have enough left burnibg to ignite the new coal. Being left with a small amount of burning coal can take a long time to get the new coal burning, or even lose the fire.

How much coal does the stove hold, loaded to near the top of the loading door? A typical scuttle holds about 20 pounds.

Please examine that bottom ash door and understand what the two apparent dampers do. I think one possibly may be thermostatically controlled.

Yes, the two controls on the bottom door are related. One's a thermostat of some sort and it's connected to a self-regulating damper. That thermostat only has settings, 0-1-2-3. It doesn't show actual temps. My problem now is that the stove seems to be running too hot. I have to keep the upper glass door open to keep it under 600. I suspect that the stove is getting air in elsewhere, but I don't know where. My scuttle might hold 20 lbs. Maybe a bit less.

Could we get pictures of the controls you mentioned, and the "upper glass door" please, or are they already posted somewhere? The temperature of the stove is controlled by "primary combustion air" which is air that comes in under the grates and then goes up thru and feeds the coal bed. Primary air is controlled manually or automatically, sometimes a little of both.

If you have to allow over fire air to bring down the temperature of your stove then much of your heat is going out the chimney. We need to fix that...

I wonder if I didn't have enough of an ash bed down when I started the fire and so that's why it was burning so hot? It's slowed down now, with all doors closed and the round damper closed, I'm at about 350-370 on the stove.
