Whenever adding fuel, take the opportunity to clean the burn
pot.
(Weekly at minimum)
• Scrape the top holed surface and sides of the burn pot
down to auger tube Figure 5.1. It is not necessary to
completely remove all material from the burn pot. The
excess will be pushed out during the next use.
• With the fire out and burn pot cold, use the supplied
allen wrench to remove any build-up that may have
accumulated in the holes of the burn pot grate. Simply
push the allen wrench down through each hole ensuring
it is clear of any build-up paying attention not to damage
the igniter element in the process.
Monthly, or after each ton of fuel burned:
• Loosen the (2) wing thumb screws on the lower front angle
of the burn pot. Figure 5.2
• Lift off the clean-out cover to open the bottom clean-out
chamber. Figure 5.3
• 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.
Figure 5.3
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 inside 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.
