Burn Pot Cleaning and Maintenance
1. Be sure the stove power is turned off.
2. Lift up and remove the front plate lock and front
plate. Set aside the front plate.
3. Remove the auger extension by pulling toward
you, then set aside (corn burnpot only)
4. Remove burnpot grate and set aside.
5. Clean all fines and debris that has accumulated.
6. Install the spare "clean" burnpot grate making sure
the 2 holes line up with the 2 tabs in the burnpot
housing.
7. Now install the spare "clean" auger extension into
the auger shaft. Make sure there isn't any corn or
debris in the shaft opening. This will prevent the auger
extension from being fully inserted into the shaft.
8. Align the auger extension through the hole in the
spare "clean" front plate and place front plate against
the burnpot grate and housing.

9. Install the front plate lock.
10. The "dirty" auger extension, burnpot grate and
front plate just removed can now be cleaned for the
next scheduled maintenance. NOTE: After cleaning
of these parts, inspect for excessive wear and
replace as needed.
Cleaning of Burnpot Parts
Cleaning can be performed in 2 basic ways:
1. Because the slag buildup will absorb moisture
from the air when cool, the parts can just be left
exposed for several days and the slag buildup will
crumble off of the parts.
2. To accelerate this process, the parts can be
soaked in water for approximately 30 minutes
(depending on the amount of buildup, they could be
cleaned in less time).
NOTE: Cleaning of these parts is not necessary until
you see that there is noticeable decrease in the
quality of the f lame in the burnpot. Example:
Unburned fuel being pushed over the burnpot.
