OPERATING INSTRUCTIONS

CONTROL BOARD FUNCTIONS

1.AUGER TRIM:

Used to change feed rates on LOW ONLY for poorer quality fuels. Push the Auger Trim button until the number 1 and 5 lights appear on the Heat Level Indicator. This will increase the feed rate to 4 seconds ON time Auger pulse. This is done only on LOW to allow the burning of poor quality fuels. Push the button until the number 1 and 4 lights appear, this will reduce the Auger On time to 2 sec- ond. This setting is for high-grade fuel only. Push the button until just the number 1 light is on, this is for a three (3) second on time (standard setting).

2.CONVECTION BLOWER CONTROL:

Used to turn the convection blower ON/OFF. Leave the convection blower ON for peak efficiency.

3.AUGER PULSE LIGHT:

This light will fl ash in conjunction with the auger. The light comes on when auger turns.

4.MANUAL AUGER FEED:

If the unit runs out of fuel, this button can be used to “prime the auger system”. This button will turn off after 60 seconds and then must be released and pressed again.

5.SYSTEM LIGHT:

Responsible for signaling the state of the control board. When the light is fl ashing during start-up, the stove is in an automatic start mode. When the light is solid, the Heat Level Setting can be altered.

6.ON/OFF BUTTON:

Used to turn the unit ON and OFF.

7.HEAT LEVEL ADJUSTMENT:

When pressed, will change the heat setting of the unit from low to high.

8.HEAT OUTPUT INDICATOR:

Shows the present heat output setting.

9.CONTROL MODE SWITCH:

Used to set the unit’s controls to one of three mode settings; manual,

high/low, or auto/off.

AUTOMATIC SAFETY FEATURES

A.The stove and insert have a low limit safety switch located on the housing of the exhaust blower. If the exhaust temperatures drop below 120°F (49°C) the unit will shut down and will be required to go through a full start up procedure again.

The most common cause for this is an empty hopper. This switch should only be by-passed for testing purposes by a technician.

B.The stove and insert have a high limit safety switch located just below the hopper behind the external body panels. If the temperature of this switch reaches 200°F (93°C), the auger will stop feeding fuel and as the exhaust temperatures drop below 120°F (49°C), the unit will shut down.

The 200°F (93°C) switch is a manual reset and should only be reset by a service person who can first diagnose the reason for failure.

The two most likely causes are Convection Fan failure or High Limit Switch failure. Either one needs to be properly diagnosed and rectified. Since this is a safety switch it should never be by-passed for any reason other than the service technician to test the operation.
