Hi all,

So I just installed my Enviro boston 1700 insert and I have two cracked firebricks. They are cracked all the way through when I shift or jiggle them. Should I leave them or replace them?

thanks!

I'd probably leave them. If they are very loose you could remove each brick and fragment and exchange it with a bottom brick.

Given the location and that it’s just the very wee corner, I would leave them. You want to change out the bricks that might actually fall into the fire!

Ok, I will leave them and monitor. I have not used this stove yet. Might do a test burn this week to ensure everything is working ok. Rather know now than wait until fall. This way I have the summer to fix/review anything.
Sweat the family out for an evening! :)

Thanks!

Previous owner was a dealer that retired and said it has little use on it. Was a non functional display and then used for 2 seasons of limited use. Date of manufacture is February 2015. Granted, he could have told me anything....but he did follow up and message me a month after I got it and asked if I had installed it yet and how it was going.

So are the ones he has pictured. I find the pumice ones crack less than standards.

I didnt load his picture. People dont realize what its like to ride in the back of a semi truck. Not a smooth ride for bricks sitting on steel.

Yeah it is not that uncommon to get cracked bricks in new stoves

There is absolutely no reason to replace them

Yes. If they are just cracked in half, they wont make any difference. There is a crack between every other brick in the stove and It fills with ash. Does not matter at all.

They just have the a tiny bit of the bottom corner cracked

Ok, Im on my laptop so I guess I could have scrolled up to see them. I cant believe a thread was made about THAT! I think in some stove manuals they tell you to replace them when they are worn in half or a third of original dimension.

My new T5 came with an extra beixk. So either they were being generous or they figure there's a real chance one won't make it through delivery in good shape. (I lucked out and now have an extra for future use.)
