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 hand-tighten the wing nut.
