Basic start up operation is as follows (with therm ostat jum ped):

1)From “Off” press operating button (Low). DC controller energizes the 115VAC relay completing the igniter high voltage connection. Igniter tem perature imm ediately rises from room tem perature.

2)Com bustion fan starts at 1 m inute along with feed m otor for 1 ½ minutes providing start up fuel.

3)Pellets start to ignite approx. 3 to 4 m inutes. Feed motor starts at 4 minutes to provide additional start up fuel.

4)At 7 m inutes unit should have flam e in burn pot. If no tem perature rise is noted by T-1 (sensor) at 20 m inutes heater starts shut down process.

TROUBLESHOOTING IGNITER SYSTEM

The igniter system incorporates a cartridge style high wattage 115VAC igniter located at the bottom of the pellet burn pot. This system is continuously cooled by incoming com bustion air and provides years of general service. However, for the igniter to work properly the burner pot must be cleaned as required to allow the pellets to fall onto the igniter. Generally, this is accomplished during norm al cleaning which would include rem oving the burn pot and brushing the ash from the pot and igniter. Rem oving the screen from below the ignitor and brushing all ash from the burn pot holder will also aid in the starting process.

Check the igniter rod surface for disintegration or obvious damage. If any white ceram ic material is showing through the SS protective cover the igniter should be replaced.

Once the burn pot is cleaned and the igniter inspected the rem aining system checks are electrical. A sim ple check of the system may be accomplished on a cold heater by placing a gloved hand on the igniter rod and pressing one of the operating button (Low). The igniter will start to get hot im m ediately (2 minute tem perature 500°F). If not

tem perature rise is noted then continue with electrical trouble shooting.

GENERAL INFORMATION

Your EASYFIRE Pellet Heater is equipped with the Autolite Autom atic ignition and operating system .

The AutoLite system is integrated into the heater to allow for autom atic start up using a heating elem ent located in the burn pot. This elem ent starts the initial fire required to burn the wood pellets. The system operates on 115VAC power supplied through a separate fuse for seven minutes during the initial heater start up. After the seven minute period the AutoLite system is deactivated and the heater operates based on the EasyFire digital control system requirem ents. If the house AC power should quit, the AutoLite system will not be available. however, with the optional battery attached the heater can be manually lit.
