I accidentally cracked the right front vertical fire brick on my 1.5 season old BK Sirocco 30.2 stove. How critical is it to get it replaced and where can I get a replacement?

If your floor bricks are the same size, take a good one out and swap it with the broken one. The crack will fill with ashes on the floor and be less of an issue especially if you keep 1/2" at least if ashes in there. Then I'd replace it after the end of the season.

This^^^

Unless you get a replacement within a reasonable amount of time.

If you choose to wait for a replacement, without disturbing any firebricks, be ginger when placing wood in the stove. You want to keep that cracked brick intact as much as possible.

I want to say that BK uses different sizes of bricks in different places. Check your manual. I would determine which brick you broke and look in the manual and then use a search. I don't think you need to buy them from BK but I don't know that for a fact. Since you will only need one, I would ask the dealer you bought from,
 
Forgot about cutting to fit. I've done that myself. Angle grinder worked good enough for me.
 
It's a lesson we all learn at some point; put in wood carefully without banging the bricks. The sidewall bricks are standard size. Unfortunately, the floor bricks are not the same size. For now, I'd just leave it alone until some spares can be ordered.

These appear to be pumice bricks and should not be replaced with standard firebrick. US Stove sells 6 packs of pumice firebrick for about $40. eBay has them along with Amazon. It's good to have some spares on hand.
 
Don't worry about it. Look where all the bricks are butted up to each other as cracks just as bad as this one. The key is that the cracked parts stay in place and they look like they are so you don't even need to bother with replacements so long as the crack stays tight.

I did replace most of my bricks a few seasons ago with regular fire bricks from the masonry yard. BK has assured us that any brick density is fine. I had several cracked and lots of erosion of the bricks. Cheap job and easy.
