I have never rebricked my entire stove and I've had it for 15 years. I have however replaced them as necessary. It is absolute hell installing them. It entails several simultaneous hand bracing with the top bricks and side bricks. I have substituted bricks other than the factory recommended kind. These are sturdier, heavier and don't crack as often. It's a Napoleon. It's a model 1900.. Should I re brick the entire box ? Please give me your opinions
