CHECK ALL SEALS
Check for air leaks around the door, glass, and ash pan and re- place gaskets as required.
Air leaks into the fi rebox will decrease the heater's performance greatly, leading to excessive soot, ineffi cient burning, and may even cause a malfunction.
Test the door seal by shutting the door on a piece of paper in various locations. If the paper can be easily slid out, air may be leaking around the door seal. Carefully inspect the door gasket and door catch.
