CLEAN THE VENT
Figure 48
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 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.
Inspect the door gasket to make sure it is fully attached. Heater 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.
CHECK ALL SEALS
Vent system should be cleaned using chimney sweep
brushes. We recommend this be done by a qualifi ed chimney
sweep.
