Pitting in back of Dauntless Flex burn?

[WNCStove]

This is the removable back plate that covers the catalytic element (not installed, awaiting catalytic kit from dealer)

After about 10 fires I’ve noticed the pitting on the back of the fire block. Is this normal/acceptable or should I bring this up with the dealer? I’ve had very poor luck actually getting straight answers out of the dealer. What do y’all think?

There is a lot of heat running through there.. You will see pitting, the more you burn. Iv heard that some species of wood contribute to it.. IDK if this is true or not.. me personally I wouldn't be.to concerned

That just looks like surface bubbles from when it was cast. Not a big deal

Agree.

The back plate on my Dauntless is pitted a little, not as much as yours though...
