Instructional Notes

The feed system is accessed on the right side of the unit. There are two hooks the assembly hangs from at the top and there is a single phillips screw that holds the assembly in place located at the bottom of the motor mount. The hollow feed spring (auger) pulls pellets up the feed tube from the hopper area and drops them down the feed chute into the fire pot.

• The whole assembly can be removed by disconnecting the power at the molex connection, loosening the phillips head screw under the motor on the motor bracket and, pulling the feed assembly out of the feed tube.
• The power can be reconnected for testing once the assembly is out of the machine.
• NOTE*- To test the assembly out of the feed tube, stuff a rag into the top of the feed tube where the assembly was mounted to simulate a closed off top which will allow the pressure/ vacuum switch to close once the stove is powered on.

Troubleshooting Notes

Mt Vernon/ Edge 60 Troubleshooting Manual.PDF

If you keep getting random error codes for 'AUGER JAMMED' but ONLY after the unit has started and achieved fire.

1. Check the auger spring set screw is tight. If it is not loose, replace the optical sensor, SRV7034-038.
2. If your feed auger spring is bent, replace it, part SRV7001-046

If you are getting a MIN FP TEMP Error Code: UNIT IS OUT OF FUEL OR CHECK FOR PROPER FUEL SETTINGS. THIS CODE WOULD DISPLAY ANYTIME THE FIRE GOT UNDER 500 DEGREES DURING ITS NORMAL RUN MODE.

1. Confirm that your fuel setting is correct for the fuel you are using.
2. Check the auger spring set screw, make sure it is tight.
3. Check the collar set screw, make sure it is tight. If it is loose, verify that there is 13" of depth from the motor mount to the end of the spring and then tighten the set screw.
4. If both of these set screws are tight and there is 13" of depth, remove the feed system from the feed tube, seal the top of the feed tube with a rag and run start-up with the feed system removed.
5. With the feed system removed try to run the unit so that you can watch the rotation of the feed spring. It should be rotating CW with the spring pointed away from you. If the motor is rotating CCW or starts CW then switches to CCW, with the feed system pulled from the stove, replace the optical sensor, part SRV7034-038.
6. Remove the vacuum hose from the drop tube and make sure there is no obstruction. If there is anything blocking, or partially blocking the inlet, clear it with some wire from a paper clip.
7. Verify that you are getting at least 3v of power to the motor across the black and white wires in the harness, if you are, replace the feed motor, SRV7000-313.
