Ah, things sure are different when you're a kid or teen-ager in a house with a woodstove vs. being a homeowner in a house with a woodstove. When you're a kid you worry whether your sister will beat you to that new box of Lucky Charms and end up with the prize or whether or not you will get a bike for Christmas . . . and when you're a teen-ager you worry whether you'll get a date for the dance or whether anyone will realize that you're wearing Lee jeans vs. Levi jeans.
As a homeowner you worry about all kinds of other things . . . like the woodstove suddenly imploding on itself in middle of the night (even though it was built to high standards), the chimney suddenly being blocked by a sudden build-up of creosote (even though you faithfully check and sweep it every month and only burn seasoned wood) and of course your deep seated fear of clowns and those bulbous red noses that they seem to really love.
As others have said, if it's any consolation . . . we've all been where you are . . . and most of us have been able to move on. I would wager that many of us have actually slept in the same room of the stove for a night or two . . . even though I sleep so soundly that I doubt I would have woke up to anything short of a nuclear melt-down occuring in stove. Many of us kept checking the thermometer every five minutes . . . ready to slam the air control lever shut, call 911 and grab the women, children and dog (or cats in my case) should the temp approach that red-colored 700 degree temp on the dial.
All I can say is that the fear will pass . . . more importantly . . . I like to think that this isn't a fear that you have of the stove . . . but rather a healthy respect for the woodstove and fire . . . and this isn't necessarily a bad thing.
Respecting the damage that a fire can create from an improperly installed, maintained or operated woodstove is in my own opinion the not-so-secret secret in running a woodstove in a home safely.
The folks who don't read the instruction manuals for floor protection, clearances, operating instructions, etc. are the ones who worry me. These are the ones who we (the FD) will eventually meet in time . . . and we will be the ones who will have to tell them that saving a bit of money by not installing floor protection, or running a single wall chimney through a wall or two, or installing the stove a mere foot away from combustibles when the manufacturer suggested 2 feet are the ones who worry me.
The folks who never check or clean their chimney worry me. The folks who dump their hot ashes in a cardboard box, paperbag or plastic bucket and then place that container on their front porch, back sunroom or in their garage worry me.
The folks who insist on using gasoline to start the fire because the unseasoned wood they have just isn't lighting worries me.
What doesn't worry me . . . knowing that the woodstove I bought has come from a reputable dealer and manufacturer with years of experience making and selling stoves . . . knowing that the professional chimney sweep I paid to install my chimney followed the installation instructions to the T . . . knowing that I have read and re-read everything I can about operating and maintaining the stove.
As mentioned . . . the ceramic glass is designed to take a lot of heat and stress. The stoves are designed to also take a lot of heat and stress. As also mentioned, I am often more worried not about the stove having issues, but rather with me and my own personal issues . . . such as trying to stuff one final split into the firebox and then realizing that it has caught on fire and will not fit (and no this hasn't happened yet . . . I caught myself right before I tried to wedge the split into the firebox) . . . or leaving the firebox door open ajar as I light that first fire and then wandering off and forgetting about it (never happened since I make a conscious decision to sit right there in front of the stove) . . . or . . . well you get the idea.
There has been a lot of good advice in this thread . . . ranging from running the stove on a weekend to see how the burn process develops, to making sure you have working smoke detectors and CO detectors, to paying attention to one's actions in regards to the doors (fire door and ash door), air control, etc.
Perhaps the best advice I can give you is to trust yourself . . .
