The 200°F (93°) - Reset the sensor and determine whether it was the convection blower or 160°F (71°C)
high limit tem- temperature sensor failure. Bypass the 160°F (71°C) sensor. Does the convection perature sensor blower not come on high? If no than replace the blower.

The heater will | - Disconnect one of the brown wires from the exhaust temperature sensor and if the unit |
not turn off | continues to operate, contact your local dealer for service. |
| - Compare the wiring diagram to the start control module and the connections to the |
| 140°F (60°C) temperature sensor. Check the connections. |
| - Remove one of the brown wires from the 140°F (60°C) temperature sensor. The heater |
| should be shut down right away as long as the start button was not pressed within 15 |
| minutes of this test. If the heater shuts down within 15 minutes, replace the 140°F |
| (60°C) sensor. If the heater does not shut down in 15 minutes, test the switch. |
| - The heater must be cold to test the switch. Pull the plug, then plug the heater back in. If |
| the heater fails to start, replace the switch. |

The heater keeps - Due to different installation set ups, length and size of venting and fuel quality, the low
going out feed setting from the factory will not always be correct. It may be necessary to experiment with feed rate vs air control. (For example, #2 may be your lowest setting).
-If the heater goes out and leaves fresh unburned pellets or
-Check to see if the air control rod is in the correct position.
-Turn the feed rate up slightly (poor quality pellets will require slightly higher settings).
-Check to see if the heater needs a more complete cleaning as well as the burn pot, venting, etc...
-Was there a power failure?
-Contact your local dealer for service
-If the heater goes out and there are no pellets in the liner, the auger is stopping.
-See "The auger motor will not function normally" and "The exhaust blower will not function normally".
Excessive carbon build up in the firebox, low heat out put
-Check quality of pellets. Even pellets from the same manufacturer can vary in quality since the materials they use to form pellets may also vary.
-Moisture content of pellets too high. Pellets must be stored in a dry place. Areas such as a garage are too damp causing pellets to absorb moisture.
Unit is burning | - Check that all exhaust and intake pathways are clear of any obstructions. |
dirty and lazy | - Burn pot is clean. |
| - Pellets are dry. |
| - Venting and terminal are clear of obstructions. |
| - Exhaust blower is operation and is clean. |
