Pre-lighting Instructions

Pre-lighting Instructions

During an initial start-up, or in the case where the hopper has run out of fuel, it will be necessary to prime the auger feed system.

To prime the auger feed system:

1.Fill the hopper with recommended pellet fuel and plug the stove into the wall outlet.

2.Press the "START" button on the control board to start the fuel feed. Next, press the "HEAT OUTPUT" button to position #5 (maximum feed rate).

3.Look through the combustion chamber door and when you see the first pellets dropping into the UltraGrate™, the auger is then fully primed. It will take 10 to 15 minutes to prime the auger.

4.Once the auger is primed, press the "STOP" button to turn off the auger (LED will go off).

Starting Your Pellet Stove

1.Make sure the auger is primed (see Pre-Lighting Instructions on this page), then simply push the "START" button on the control board to activate the Fastfire™ igniter.

2.While the pellets will ignite on any heat output setting, it is recom- mended that the "HEAT OUTPUT" button be set to position #3. Pellets will start feeding into the UltraGrate and should begin to ignite in approximately seven minutes. The Fastfire igniter will automatically shut off after fifteen minutes (on hot starts igniter will shut off after seven minutes).

3.After the pellets are burning well, press the "HEAT OUTPUT" selector to the desired setting. Combustion air and the pellet fuel feed rate will adjust automatically as the "HEAT OUTPUT" button is pressed. The flame should be bright yellow in color and there should be no evidence of soot formation at the top of the flame. Press the "BLOWER" speed button to increase or decrease the blower speed to the desired level

4.If operating your stove with the wall thermostat, adjust the "HEAT OUTPUT" button to the desired demand mode (#1 through #5 on the "HEAT OUTPUT" button). Next, adjust the wall mounted thermostat to the desired room temperature and your stove will automatically switch between a demand mode and stand-by mode.

Notes:

Cold Start - When the "START" button is pressed when the appliance is cold, voltage will bypass its normal circuit through the low limit thermal switch (for 25 to 35 minutes to allow adequate time for the low limit thermal switch to heat [140° F min.] which will close the circuit). The combustion and convection blowers will start at maximum speed. After approximately 10 seconds both blowers will default to settings they were at after the last shut down was completed (indicated by LED's #1 to #5). The Fastfire igniter will operate for approximately 15 minutes. The auger will turn continuously for a predetermined dura- tion at the respective Heat Output Settings, followed by the normal operating mode.

General Operating Considerations

Proper Burn Characteristics: Your flame should be bright yellow under normal operations. If your flame becomes reddish/orange, your stove probably needs routine maintenance. Excessive amounts of fly-ash build- up in the UltraGrate, clinkers in the UltraGrate, or leakage of air if the UltraGrate is not properly seated, will starve the fire for air. (See Routine Maintenance for information on cleaning the stove). If the problem per- sists, review the troubleshooting section at the end of this manual.

Manual and Automatic Operation

Your pellet stove can be operated in either the manual or automatic mode. The manual mode is used when operating without a wall thermostat. The automatic mode is used when utilizing a wall thermostat. When utilizing the thermostat capability, the burn time can be extended dramatically depending on thermostat setting. Note: It is normal for some ash to build up on the inner glass surface at the lower Heat Output settings.

Manual Operation

Pressing the "START" button will initiate the start-up cycle. The auger LED will be green to indicate the “on” status. The blower speeds and pellet feeds are fixed during this time to provide appropriate ignition. The Fastfire igniter system will light the pellets fed to the UltraGrate, after about 3 minutes. After the start-up cycle, your stove will be in the run mode. At this point the stove will operate with the heat output ("HEAT OUTPUT" button) and blower settings ("BLOWER" button) selected. These settings can be selected either during or after the start-up cycle. Pressing the "STOP" button during the run mode will initiate the shut down cycle (feeding LED will go off). The pellets will stop feeding and the blowers will run at a fixed speed for approximately 10 minutes. At this point your stove is safely shut down. The stove can be restarted by pressing the "START" button during the shut down cycle.

Automatic Operation

Your stove is capable of running in an automatic mode with the use of a wall thermostat.

For the wall thermostat to control the operation of the stove, set it to a temperature that will put it in the demand mode (calling for heat). The thermostat will establish either a demand mode or a stand-by mode. The thermostat should be set for the desired room temperature. If the room temperature drops below the level on the thermostat the stove will automatically begin the start-up cycle, as explained in the Manual Operation section.

Once the start-up cycle is completed the stove will operate at whatever heat and blower setting you have selected. For best operation under thermostat control, the medium or high settings are recommended. When the desired room temperature is reached the stove will automatically go into the shut down cycle. The pellet feed will stop and the blowers will continue for a controlled time allowing safe shut down of your stove. All lights will remain on when the thermostat is open. The "HEAT OUTPUT" and "BLOWER" settings can be changed at any time, but only take affect during the run mode. When the temperature in the room drops to the level set at the thermostat, the stove will again begin the start-up cycle and resume automatic operation in the demand mode.

Note: If the "START" button is pressed while the thermostat is in the standby mode the stove will not restart until the thermostat closes (call- ing for heat).
