Cleaning the heat Exchanger System

1. Remove brick panel and flame guide. (See Pg 24.)
2. Remove the ash pan. See Page 21.
3. Remove flue baffles located on each side of the
burnpot, see Fig. 48 & 49. 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. 49.
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. 50 & 51. 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.
52.
8. Scrape all of the heat exchanger surfaces. (Be sure
to clean any internal ledges where fly ash could have
collected.)
