High Ash Fuel Content Maintenance; Blower Replacement - Quadra-Fire CB1200-B Owner's Manual

CB 1200 Pellet Stove
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.

fuel caused by poor quality pellet fuel

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.

screws securing the screen to the unit.
