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 37.1 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 37.2.

The correct flame size when good quality, premium pellet fuel is burned is shown in Figure 37.3.

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

IMMEDIATE ATTENTION AND CLEANING IS REQUIRED.

WARNING

Fire Risk.

•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.
