In Reply to: Cracks in Combustion Chamber posted by Todd on December 19, 2006 at 08:43:52:
Stress cracks in fire chamber walls is normal. It is very stressful to have the fire go on and off several times an hour for years. If you notice the material next to the crack start falling off or see paint changes outside, then have the chamber redone.
