G200 refractory firebrick nozzle cracks/ chunk
« on: December 02, 2017, 05:24:21 AM »

He’ll all,  so far been the start of another good heating season. No issues last year at all with my G200, worked flawlessly.

This year, startup was mint... and been good. Super clean burns, and all appears well.  Yesterday I opened the reaction chamber for the first time in a week or so and to my dismay found a chunk of refractory brick laying in the bottom of the curved brick.  It came from the bottom side of the right nozzle brick. Didn’t know it was hollow.

Machine seems to still be working fine, gassing perfectly well. Fingers crossed.  My local dealer is gone, and now the only guy is in New York 6-7 hrs away(but doesn’t have any bricks anyway). In classic form I go back to sea in 10 days as winter is really cranking up.

Any thoughts on if it’s fine to keep going? And anyway to get bricks in the next week ? And anyone else had this problem?

Looks like the other side is cracked too, so probably not too far behind.

Thanks in advance.

Here’s a couple pics if I can post them.

There pretty self explanatory, one is looking up from underneath, the other is the chunk itself.

For some reason the pic is displayed upside down. Not sure why.

I'd give the factory a call on Monday and see what solution you can work out.  The brick isn't hard to lift out. They make it tapered for easy replacement. 877-325-9792
You can keep running but it could run a little smoky. You won't damage anything.

Thanks for the information, I plan to call this morning. 

I suspect as long as the top part of the brick stays intact, which will maintain the nozzle dimension size, I think I’ll be alright.

Keeping my fingers crossed.

Love the unit, burns so darn clean with decent wood, and cold temps!

Just an update. The factory was able to send me some bricks....  unfortunately they didn’t show till I left. So I’ve asked the wife to be ginger throwing wood in, a real solid chunk of red oak coils surely help the top side crack too!

The factory says they have changed a few things in the way the pour the refractory which they hope will help it last longer. I hope so too. Just barely a year is too short.

Hope it hangs on for a couple more weeks till I get home. Fingers crossed.
