Maintenance
Scrape the burnpot to remove any carbon deposits which may have formed.
Scraping can be done while the boiler is in operation, accessed through the firebox door opening. Wear gloves to protect from burns.

Burnpot Cleaning:
The burnpot should be cleaned no less than once a week. For best operation the burnpot should be cleaned every time the hopper is filled with pellets. The fire does not have to be out to scrape the burnpot although it is recommended the boiler be on minimum burn at the time of cleaning.
CAUTION: Wear Gloves To Prevent Burns.
Use the flat end of the scraper provided to scrape down over the holed surface of the burnpot grate. See Fig. 17. It is not necessary to clean out the scrapings from this cleaning because they will be pushed out as the auger operates.
Note: Make a special effort to scrape the bottom inside corners of the burnpot where the auger tube enters the burnpot. Carbon deposits can build up over time in this area that may cause a restriction to the flow of pellets into the burnpot.
Note: The end of the scraper may need sharpened occasionally, for best results.
While scraping the burnpot, you can also use the scraper tool to tap on each of the visible heat exchange spirals. This will help to maintain maximum efficiency between cleanings.
Cleaning the Burnpot Air Chamber:
This area only needs to be cleaned twice a heating season, unless excessive buildup is noticed during scheduled cleanings.
There is a cover on the front of the burnpot to gain access to the air chamber. The cover is held into place by two thumb screws. Loosen the thumb screws and remove the cover. See Fig. 19. The air chamber can be cleaned of any ash that has fallen through the holes during operation and cleaning.
NOTE: ALWAYS REMEMBER TO CLOSE THE CLEANOUT COVER AFTER CLEANING.
Feeder Chamber (Fig. 20):
This chamber may get a buildup of fines from the feeder mechanism movement. This area should be checked and cleaned at least once a year.
To remove the feeder cover:
•Loosen the 5/16” wing nut.
•Slide the cover off of the threaded stud and lift upward.
•Inspect and clean the inner chamber as necessary. See Fig. 20.
•There is a removable plate in this area that deflects fines into the auger. To remove this plate, roll it out under the pusher arm.
•Reinstall the cover making certain it is centered on the feeder body and
