PART 2
I know this is a lot to read and take in at first, but it really is a simple process. Basically, you're going to build a fire with nice dry kindling and some newspapers tied into loose knots. You can build a kindling-only fire and then add spits, or you can build a "top down" fire where you build up your kindling and paper on top of some splits. Either way, you're going to have your primary air control fully open (and maybe even have the stove door cracked a bit) so that the fire will draw in the greatest amount of air possible and produce a quick, hot, and clean burning fire with good draft.
Once you have an established coal bed, you'll begin to add larger splits to your fire. Having then added a good load of larger splits, you'll usually leave the primary air fully open until the wood becomes "fully engaged" with primary combustion. After a few minutes (again, with seasoned wood), the wood will have charred black on the outside. At this point you'll start reducing the amount of primary air you give the wood (at this point, my stove top thermometer is usually reading between 450-500F). I usually reduce the primary air in stages over a 20 minute period or so (depending on the species of wood, size of the splits/load, etc.). As you reduce the primary air, you'll notice that the fire "moves" from the bottom of the wood to the top of the wood. This is the secondary combustion - the gases and smoke released from the charred wood will meet the hot, secondary air coming out of the tubes and ignite. It makes a beautiful, hypnotic fire.
Some non-cat stoves have an additional lever that may control a sort of "heat output" or "thermostat" type mechanism built into the stove, but for the most part the only moving parts you'll have on a non-cat stove is the primary air control. You'll quickly learn your optimal air setting for the type of burn you want.
A catalytic stove will have an additional lever called a bypass lever. This lever simply allows the smoke from the fire to "bypass" the catalyst and go straight up the chimney. Until the cat becomes hot enough to burn the smoke, it will not operate properly. So, until you get the cat hot enough, you'll leave the bypass open. Once it's hot enough, you simply close the lever, which forces the smoke through the catalyst which is treated with a special substance to help the smoke to ignite at a lower temperature than in a non-catalytic stove.
Each type of stove has its advantages and disadvantages. Cats are renowned for their long burn times, for example. But some people don't want to take the catalyst out and clean it and/or replace it when necessary. Most cat stove operators will tell you that this is both quick and easy. I've never operated one, so I can't give you an informed answer.
As far as overfiring goes, most manufacturers will tell you at what temp you're overfiring your particular model of stove. Get a $15 magnetic Rutland thermometer from Tractor Supply and put it on the stove top. Overfiring is usually the result of: leaving the door ajar too long after you've started a fresh fire and walked away (which you should never do), leaving the primary air open too long with a full load fully engaged, or adding fresh splits to an already established fire in the middle of a burn cycle.
Do some reading here (broken link removed to http://www.woodheat.org/technology/woodstoves.htm) to familiarize yourself with the two types of stoves. Properly installed and properly operated with dry, seasoned wood both are easy to operate and, more importantly, SAFE to operate.
