Glass freak out

[tsquini]

It happens I don't like it. I move it off the glass after it happens. If the wood burns on the glass I get a black spot on it. I don't like the black spot.

Wow that's a new one. Hopefully the fire was not running at the time, although the newer stoves at least seem to have 2 panes of glass.

I had it off the stove while I was cleaning it, so no fire.

I had a broken glass last year! I was really mad that my 5yr old decided it was a good thing to hit with daddy's hammer. $100 later and i was burning again.

I told the story before but twenty five years ago I was in a stove shop when the owner picked up a phone call. When he got off the phone he laughed and said it was a very young voice asking how much a stove glass would be and could it be installed before six that evening.

I have learned to leave well enough alone - sometimes going in to reposition a roll off cause a bunch of hot embers and coal to jump out on the lip of the stove and on to the ember mat. I would rather clean the glass than fuss with getting the hot embers/coals back in the stove

That's the conundrum. If you open it up to get the wood away from the glass, you've got a good chance of having a worse mess on your hands with wood and embers falling out, unless you can manage to get a tool in there to get the wood away from the glass with the door opened only a little bit. If you can do that, you're better off than having the burn on the glass, my experience anyway.

Of course you avoid this problem almost completely if you have a stove which can load full size splits NS. And that was one of the reasons I only selected from NS inserts like the Summit.

My brother had a split roll against the front glass on his jotul 600 and the glass cracked.
May be already stressed from a clip, who knows, it does happen.
I've had one crack the first time a brand new stove got to 600º. Right under a clip. Screw had to be torqued down just a tad too much.

The only time I FREAKED OUT was when the glass slipped out of the front door with a fully loaded and burning firebox in my VC Resolute. It was held in by a couple tiny clips that had worked loose. I jammed some aluminum foil over the missing glass and watched the stove for 8 more hours until it was down to coals!

Fun times.

Per the UL safety standard for wood stoves, the glass must pass a few tests...

With maximum intensity fire.
1. Wipe down the glass with a rag fully saturated with room temp water
2. Three sprays of water from a suitable spray bottle.

Before, during, and after a radiant fire.
1. Impact test

See the attached drawing for the impact test. The steel ball in the impact test is 1.18 pounds and "h" is 16.25 inches.

I am glad you posted this. We load our stove (a Napoleon 1400PL) N/S and tonight one of the logs is a bit close to the glass. The door shut easily, but we have a big black smudge on the corner because that one piece was of course, was a bit damp and I could see it bubbling and I was terrified the bubbling would cause the glass to crack. As of right now it hasn't. Glad to know it takes effort to crack the glass.
