CHECK ALL SEALS

Check for air leaks around the door, glass, and ash pan and replace gaskets as required.
Air leaks into the fi rebox will decrease the appliance'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.
Inspect the door gasket to make sure it is fully attached. Appliance gasket cement can be used to re-attach if
necessary. If the door gasket is worn or fl attened, replace.
Check the door to make sure it latches correctly. The latch should engage with a slight amount of resistance,
yet not be too diffi cult.
If the glass is cracked, replace.
