Auto-Ignition Cycle
The Ignition cycle is around a 10 minute cycle. At the beginning, the combustion
blower, igniter, and feed motor all come on. After 3 to 5 minutes, the feed motor
stops. Now the burn pot is loaded with fuel.
The heated air from the igniter passes through the bottom row of holes, and
heats the pellets to their ignition point. As the pellets are heating up, they
will produce some smoke. Now is a good time to check for leaks in the
venting system! When the gases get hot enough to ignite, the smoke will
change to flame and the fire is started.
As the fire burns and the exhaust temperature increases, the feed motor will
run to keep the temperature increasing. When the exhaust temperature
reaches around 140, the igniter will shut off.
