SCF 050 CORN FURNACE Installation & Operations Manual

1. A closer look at the Control Board to the right in figure 14 will explain how the board ON OFF works There are five buttons labeled 1 through 5 a slide switch labeled 6 and a LED Light bar with 5 Heat Settings The LED Light bar is also used during the Diagnostic process see page 28 for more details The buttons on the board function as follows Refer to Figure 14 The touch pad buttons are labeled with the white numbers 1 through 5 1 The Heat Level button 1 will advance the setting between level 1 and 5 Once you reach level 5 it will drop back to level 1 Each level has a LED light to indicate where Figure 14 the board is set SCF 050 Manual 25 Sold and serviced by www PelletKing com 603 424 1183 2 The On Off button 2 turns the Furnace On and Off It will also reset the board after the board has sensed a problem and is flashing a Diagnostic code 3 The auger button 3 will allow the customer to manually auger corn into the burn pot on start up when needed This is particularly helpful in priming the Auger Tube when it is empty 4 The Draft Trim button 4 allows for adjusting the Exhaust fan voltage on Heat Level 1 only Push the button and the all of the LED Lights in the light bar will flash once This decreases the voltage approximately 5 volts below the default setting Push the button a second time and all of the LED Lights in the light bar will flash twice This increases the voltage approximately 5 vol

3. Also make sure you are using clean corn Otherwise this is mainly caused by improper combustion See Damper Adjustment section of the Operations Manual Besides the damper adjustment there are several areas that can have an effect on the combustion process Solution Check all Gaskets Doors and door Latching Systems for air leaks Any leaks in these areas will negatively affect the burn process and cause the pot to overload Also make sure the slide out bottom is closed all the way If this is left open combustion air will leak out the bottom of the pot area instead of being used in the combustion process 3 My Furnace runs for approximately 6 to 10 hours and then overloads the Burnpot What s wrong Solution This most likely means the combustion process is taking place on top of the Coal Rake During normal burning of corn the Coal Rake must be pulled out of the burnpot This causes the pot to fill up prematurely and overload The coal rake will be damaged if left in the pot for long periods of time 4 My Furnace isn t burning and the number 2 LED light is blinking This diagnostic light indicates the vacuum switch no longer senses negative pressure in the firebox area of the Furnace What caused the Furnace to go out The door of the unit was left open longer than 60 seconds See solution The ash pan door was left open for longer than 60 seconds See solution The combustion fan is not running Defective fan or control bo

5. Proper installation is essential for safety effective Operation Warranty Coverage Insurance requirements and to meet Local Building Codes Installation Requirements are described in the first section of this manual Verify the installation is correct before firing up the furnace for the first time When burning corn care should be taken in how the venting system is installed To burn corn the moisture content should be 15 or less This is much higher that the moisture content of wood pellets and can result in condensation forming in the venting system in certain installations The chimney system should stay within the warm envelope of the house as much as possible Only penetrate the exterior of the home where the exhaust system will terminate REMEMBER Condensation from a corn furnace is detrimental to the venting system Only buy venting systems that are warranted with burning corn PREVENTING CHIMNEY FIRES Chimney fires can be prevented by properly operating the Furnace and by periodic inspection and cleaning of the chimney When wood is burned it produces tar and other organic vapors which combine with expelled moisture to form creosote The creosote vapors condense in the relatively cool chimney flue associated with a slow burning fire As a result creosote residue accumulates on the flue lining When ignited this creosote can result in an extremely hot chimney fire The chimney and chimney connector should be inspected at least once ev

13. the burn pot rapidly turns into glowing coals If you see a lot of unburned corn in the pot an adjustment may be needed In an unbalanced pot the corn will quickly stick together and prevent the proper flow of combustion air The pot will overload and the fire will go out When burning pellets make sure to check for the formation of creosote in the unit and venting system Constantly running the Furnace on a low setting with too much combustion air may cause creosote to form Burn pot temperatures can be too cool when burning on low with too much draft Once the damper is adjusted for your installation it should not be necessary to make any further adjustments to the damper The combustion air is automatically increased every time the feed rate is advanced on the control board If you notice a difference in the operation of the Furnace first check to see if the Furnace needs cleaning Then check to see if there is a change in the fuel you are burning The moisture content of your corn may be too high or the quality of the pellets you are burning may have changed Break in requires the burning of 15 bushel of corn or 15 bags of pellets or a continuous burn for two weeks 0 D E The setscrew is a useful tool in Sms making adjustments to the Air Intake damper Adjust the damper by turning the screw one half turn clockwise and place the damper blade against the screw Wait 10 minutes to allow the burn to adjust to the new setting Making to
