1. Convection Blower Replacement
a. Use proper shut down procedures to shut down the
appliance and let it completely cool.
b. The convection blower is located at the bottom rear
of the appliance. If an outside air kit is also installed,
depending on your particular installation you may or
may not have to remove the outside air flange. If you
do, remove the 2 screws using a Phillips head screw-
driver. You do not need to remove the flex pipe from
the flange.
c. Remove the lower rear screen by removing the 4
screws securing the screen to the unit.
d. The motor is mounted on a removable bracket. Remove the
2 screws just above the motor and the whole assembly will tilt
down and pull out.
e. Disconnect the wires from the blower. The wires coming
from the wiring harness are white, red and tan and the
wires coming from the blower are black, white and red.
The white connects to white, the red to red and black to
the tan color wire.

Poor quality pellet fuel, or lack of maintenance, can create
conditions that make the firepot fill quickly with ashes and
clinkers.
This condition makes the appliance susceptible to overfill-
ing the firepot with pellets which may result in smoking,
sooting and possible hopper fires. Figure 33.1 shows an
example where the firepot overfills, pellets back up into the
feed tube and ash has accumulated in the firebox.
An inefficient and non-economical method of burning of
fuel caused by poor quality pellet fuel is shown in Figure
33.2.
The correct flame size when good quality, premium pellet
fuel is burned is shown in Figure 33.3.
If the ash buildup exceeds the half way point in the firepot
IMMEDIATE ATTENTION AND CLEANING IS REQUIRED.
Fire Risk.
WARNING
• High ash fuels, or lack of maintenance, can
cause the firepot to overfill. Follow proper
shutdown procedure if ash buildup exceeds
half way point in firepot.
• Failure to do so could result in smoking,
sooting and possible hopper fires.
