Monthly Cleaning- continued:
1. Remove flue baffles located on each side of the burnpot.
Figures 5.9 & 5.10. The baffle is held in place by inserting
the tab into the slot (located toward the outside of the
firebox) and resting on the hook tab located beside the
burnpot.
2. Pull the pointed end of the baffle slightly front with one
hand while pushing up from below with the other hand.
Figure 5.10.
3. With the baffle released from the tabs, rotate the pointed
end toward the door opening. Lift baffle up and out.
The right and left baffle are interchangeable.
4. Now remove the heat exchanger baffle plates. Figure 5.11.
To remove the left plate, slide the center lock to the right.
To remove the right plate, slide the center lock to the left.
(The right and left plates are interchangeable.)
This will allow access to all of the rear vertical heat exchanger
surfaces.
5. With all four baffle plates removed, cleaning can be
performed with the arrow end of the scraper. Figure 5.12.
6. Scrape all of the heat exchanger surfaces. (Be sure
to clean any internal ledges where fly ash could have
collected.)
