Troubleshooting & Frequently Asked Questions - St. Croix SCF-Revolution Installation & Operation Manual

TROUBLESHOOTING & FRQUENTLY ASKED QUESTIONS
The Furnace is very trouble free in operation when properly maintained and quality fuel is 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
1. When first starting the Furnace remember the auger tube is empty, which will delay feeding fuel
to the burn pot. This will in some cases prevent the Furnace from starting.
Solution: First allow the Revolving drum to rotate after turning the furnace on. Prime the
burn pot if the auger tube is empty.
2. My Furnace keeps overloading the burnpot. First check the moisture content of your corn. It
should be 15% or less. 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.
3. 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?
a.
b.
c.
d.
e.
f.
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.
4. My Furnace isn't burning and the number 3 LED light is blinking. This diagnostic light
indicates that the Proof of Fire Switch no longer senses a fire in the Furnace. First check to see if
there are pellets in the hopper. If there are pellets in the hopper, why did the Furnace 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 board)
The vacuum switch is defective.
The vacuum hose is disconnected
The vent system is plugged with fly-ash.
