EF AutoLite Igniter
Replacement Instruction
WARNING - ELECTRIC SHOCK POTENTIAL.
All repairs must be accomplished with the
115VAC and 12 DC power disconnected from
heater.
GENERAL INFORMATION
Your EASYFIRE Pellet Heater is equipped with the Autolite
Automatic ignition and operating system.
The AutoLite system is integrated into the heater to allow for
automatic start up using a heating element located in the
burn pot. This element 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 requirements.
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.
Basic start up operation is as follows (with thermostat
jumped):
1) From “Off” press operating button (Low). DC controller
energizes the 115VAC relay completing the igniter high
voltage connection. Igniter temperature immediately
rises from room temperature.
2) Combustion fan starts at 1 minute along with feed motor
for 1 ½ minutes providing start up fuel.
3) Pellets start to ignite approx. 3 to 4 minutes. Feed motor
starts at 4 minutes to provide additional start up fuel.
4) At 7 minutes unit should have flame in burn pot. If no
temperature rise is noted by T-1 (sensor) at 20 minutes
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
combustion 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 normal
cleaning which would include removing the burn pot and
brushing the ash from the pot and igniter. Removing 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 ceramic material is showing through
the SS protective cover the igniter should be replaced.
Once the burn pot is cleaned and the igniter inspected the
remaining system checks are electrical. A simple 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
immediately (2 minute temperature 500°F). If not
temperature rise is noted then continue with electrical
trouble shooting.
