Maintenance - burn Pot
burn Pot cleaning and Maintenance
1. Scrape the top holed surface and sides of the burn
pot. (Fig 39) It is not necessary to completely remove
all loose material from the burn pot. The excess will be
pushed out during the next use.
danger
Disconnect the power to the unit before
removing cover.
2. Loosen the (2) wing thumb screws on the lower front
angle of the burn pot. (Fig. 39)
3. Lift off the clean-out cover (Fig.40) to open the bottom
clean-out chamber. (Fig.41)
4. Clean ash buildup from inside the chamber while
cover is off. Use the scraper to tap on the top front
edge of the burn pot. This will help knock pieces of ash,
loosened by the scraping process, down through the
holes. It also helps knock scale off of the igniter element.

The igniter is made to be removable for service
by insulated male/female wire connectors. These
connections between the hot leads (the wires inside the
burn pot) and the cold leads (the wires from the control
board) are always pulled to the rear of the feeder body.
(not coiled inside the burn pot.)
It is very important that these connections are to the
inside rear of the feeder body. Also, the extra wire of
the igniter wire service loop must be pulled out through
the rear of the feeder and tied up so that it will not be
damaged by any moving parts.
note: the hot lead/cold lead connection must
always be pulled to the rear of the feeder body
before operation.
warning
use caution when cleaning burn pot clean-
out chamber. do not damage the high
temperature igniter wires.
creosote Formation and the need For removal:
Whenever wood is burned, there is a potential for
creosote formation. The venting system should be
inspected periodically during the heating season to
determine if a creosote buildup has occurred. If a
significant layer of creosote has accumulated (3 mm
or more), it should be removed to reduce the risk of a
chimney or venting system fire.
