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.

removed to reduce the risk of a chimney or venting system
