    the Furnace is put back in service, (Defective Room Fan, dirty Room Fan, dirty Return Air Filter, defective Fan Limit Control or possibly a bad Control Board) 2. Proof of Fire switch also called the P.O.F. This senses the temperature rise in the exhaust system.
  • Page 32 When burning corn, wheat, rye & Distiller’s Grain pellets the burn pot should be “BALANCED”. This means the fuel that is being augered into the burn pot rapidly turns into glowing coals. If you see a lot of unburned fuel in the pot, an adjustment may be needed.
  • Page 33 If you experience problems adjusting the Furnace during the Break-In Period, contact your dealer. The figure below may be used to gage the approximate damper setting when making an adjustment. Some chimney systems will fall outside the norm, for example, a chimney with excessive draft or one with a long horizontal run. In dealing with technical support, the terminology listed in figure 16 may be used to clarify where your damper needs to be set.
  • Page 34 Terminology used when burning Grain ( corn, wheat, rye & Distiller’s Grain) 1. Balanced burn pot. This means the rapidly turns into red-hot coals once it is in the burn pot. 2. Lag time. This is the time it takes for the corn, wheat or rye to start burning and the burn pot to become balanced.
  • Page 35 e. Advance the heat setting to #5 and let the Furnace burn at this setting for ½ an hour. Check the burn pot to see if it is balanced. A small damper adjustment might need to be made at this time to make sure the “Lag time” isn’t too long. Remember: Only turn the setscrew one 1/2 turn clockwise to open the damper.

  • Page 36: Thermostat Control & Pilot Settings

    The Furnace may be controlled with a thermostat to help maintain a more constant temperature. A Multi-Fuel furnace, such as the SCF 050, will be a little slower in reacting to a thermostat than the typical Gas, Electric or Oil fired furnace. With this in mind we have incorporated 3 Pilot settings on the control board (See Point 5 on Page 25).

  • Page 37: Clinker/Ash Removal

    Once a clinker/ash has formed in the burn pot, it must be removed or the Furnace will go out. The St. Croix Burn system is designed to remove the clinker/ash without loosing the fire in the burn pot. It is a 3-part system.

  • Page 38: Daily Maintenance

    CAUTION: THE DOOR AND FRONT PART OF THE FURNACE WILL BE HOT. DO NOT TOUCH ANY PART OF THE FURNACE THAT IS HOT! Daily Maintenance Example of Schedule for dropping Clinkers and Ash from burn pot: This may be required more than once a day, depending on the burn rate of the Furnace and the quality of Corn, wheat or rye or pellets used.
  • Page 39 1. The coal Rake. The first step is to push the coal rake in and shave the coals off the top of the clinker. Once this is done open the door and add a ¼ cup of pellets on top of the coals (See figure 18). To push in the Coal rake, use the Rod Handle tool shown in figure 20 on page 39.
  • Page 40 4. The control board. Set the heat setting to #1 for a few seconds and return to the setting it was on. This initiates the time delay for dropping the clinker. 5. Dropping the coals back into the burn pot. At this time pull the coal rake back out of the burn pot to drop the coals in the pot.

  • Page 41: Periodic Maintenance

    Periodic Maintenance CAUTION: Periodic maintenance should only be done while the Furnace is shut off and cold. 1. Ashpan. Empty the ash pan when it appears full (approximately once a week). The frequency of cleaning the ash pan will depend on the quality and amount of fuel being used.
  • Page 42 3. Clean-Out Ports. The Furnace has 3 Exhaust Cleanout Ports located in the LEFT AND RIGHT lower corners of the firebox and behind the Ashpan. Remove covers and clean regularly. Figure 21 Frequency of cleaning depends on the amount of fuel being burnt and the quality of the Corn, wheat, rye or pellets.

  • Page 50: Operation

    TROUBLESHOOTING & FRQUENTLY ASKED QUESTIONS The Furnace is very trouble free in operation when properly maintained and quality pellets are used. When the Furnace fails to operate properly, troubleshooting by the operator of the Furnace is limited. Please read the following guide for answers to frequently asked questions When first starting the Furnace remember the auger tube is empty, which will delay feeding fuel to the burn pot.
  • Page 51 Solution: If the fire is out, re-light the Furnace. If the fire is still burning make sure all doors are securely latched and hold down the On/Off button (approximately 5 seconds) until Furnace starts up again. This will re-start the Furnace in the start-up program.
  • Page 52 Replace with a 250 Volt, 5 Amp fuse. 10. Why is my glass dirty? Normal operation of your St. Croix Furnace will produce a white build- up on the glass that wipes off with a dry paper towel. However extended burning on the low setting only will produce a light tan color.
  • Page 53 The default Pilot setting has an On Time of 2.5 seconds. The #1 LED light indicates the default pilot setting. This setting requires little fine tuning. Pressing the Feed Trim button once will turn the #1 and #4 LED lights on at the same time. This reduces the On Time to 2.0 seconds.
  • Page 54 12. How do I adjust the draft for the Pilot settings (#1 setting)? Not all fuel burns at the same rate. The moisture content of corn, wheat or rye greatly influences how it burns. Burning Pellets requires adjustments to the low burn to prevent Creosote from forming. Following is a description of the function of the Fan Trim button.
