Got Ready to Get the Koker Fired up- Noticed Glass Cracked

A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

Getting ready to fire it up and noticed a crack all the way down top to bottom on the glass. It was fine when I shut her down and got her ready for summer.
Can I still use the koker until I get a replacement? What would have caused it? Do they eventually weaken in time?( It is probably four or five years old)
Thoughts and comments?

I have a spare. I would not use my stove if it was not as configured from new. Safety is always the way to go. Sorry to be so negative to less than perfect.

I found a crack in mine right before I started it up several years ago, didn't want to postpone the startup so I just put a good smear of high temp silicon on & worked it in with my finger on both sides. Got a new glass & maybe one of these days I'll get brave enough to attempt a change but those little bolts look like snappers to me so it will be after a shut down for sure.

x2. I've had bad experiences with bolts that hold the window glass becoming fatigued and breaking off with very little force applied. I have no direct experience with those bolts on a Koker, but I agree with samhill that a temporary seal should be ok, and that you should allow time for things to go wrong when changing the glass.

Thanks for the advice Sierra 2001, I'll order a replacement with a spare. In the meantime, I'll take Samhill's and Mike's advice with the high temp silicone and wait if possible for shutdown to try replacing it.
