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.

brush or rag through the inside of the tube and
out the exhaust blower housing.

housing.
5. With a bristle brush vacuum, clean the blades of
the motor.
6. Place the new exhaust
blower mounting gasket
around the screw holes
being very careful not to

7. Re-attach the wiring to the motor and place it back
on to the housing, taking care that the side of the
motor does not tear the gasket and then re-attach the
nuts.
