In big trouble here..one piece of my firebrick just fell out..I have a fire going in the box..I fished piece of brick out of the flames..I have a woodpro 2.0 stove and have had a few problems with it..we heat our home with this stove..is on our first floor..so I can't just take stove apart and work on it as it is winter here..will it hurt for me to use stove with the small piece of fire brick missing..I might be able to jiggle it back in when stove cools...its warm enough today to let fire go out..I bought this stove with no experience or real fact finding ...its not the best, I'm sure..I could replace it if necessary..but don't want to but anything else without advice..thanks for your help!
