D. High Ash Fuel Content Maintenance

•Frequency: When the ash build-up exceeds more than half way up the firepot.

•By: Homeowner

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 32.1 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 32.2.

The correct flame size when good quality, premium pellet fuel is burned is shown in Figure 32.3.

If the ash buildup exceeds the half way point in the firepot

IMMEDIATE ATTENTION AND CLEANING IS REQUIRED.

E.Blower Replacement

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.
