3.Remove flue baffles located on each side of the burnpot, see Fig. 49 & 50. The baffle is held in place by inserting the tab into the slot (located toward the outside of the firebox) and resting it on the hook tab located beside the burnpot.
4.Pull the pointed end of the baffle slightly front with one hand while pushing up from below with the other hand. See Fig. 50.
5.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.
6.Now remove the heat exchanger baffle plates. See Fig. 51 & 52. 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.
7.With all four baffle plates removed, cleaning can be performed with the arrow end of the scraper. See Fig. 53.
8.Scrape all of the heat exchanger surfaces.(Be sure to clean any internal ledges where fly ash could have collected.)
