a.
Unburned fuel in the burnpot means the fire went out before the auger quit
feeding.
A power Failure could also cause this. If the furnace is still hot when the power comes
back on, the feed system will resume. If the fire had gone out in the pot, the feed would
continue to run until the Proof of Fire switch dropped out and shut the Furnace down.
Solution: Too much Combustion Air on the pilot setting. Adjust the air damper. (See section
covering an Unbalanced Burnpot). Corn/Pellets would still feed until the P.O.F. switch
eventually shuts the Furnace down. Adjust the damper. (See Damper Adjustment in the
Operations Manual)
b.
If all the fuel is burned up means the auger quit feeding fuel while there was
still a fire in the burnpot. Check to see if there is fuel in the hopper. If the hopper
is empty, fill the hopper and re-light the Furnace.
If there is fuel in the hopper check to see if there is an obstruction in the auger system or
if the auger set screw is loose.
Solution:
Remove obstruction and re-light the Furnace or tighten the setscrew on the auger
shaft.

My Furnace isn't burning and the #4 LED light is blinking. This means the high Limit has
shut the Furnace down. The Convection Blower could be defective or may need cleaning. The
high limit switch may be also defective. It is best to call your dealer for support when trying to
troubleshoot the High Limit Switch. Do not use your Furnace if the High Limit switch frequently
trips.
6.
I turned the Furnace on with the On/Off switch and nothing happens. First check to see if
the Furnace is plugged in and the receptacle has power to it.
Solution:
Check the fuse on the back of the control board. Replace with a 125 Volt, 5 Amp
fuse.
7.
Why is my glass dirty? Normal operation of your St. Croix Corn/Pellet 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 tan color. These types of build-up on the glass are normal. A
heavy black build-up on the glass could indicate a problem.
Solution:
Adjust the combustion air setting to the proper setting. If this doesn't seem to
help, make sure the clean out cover plates are installed in the Furnace. It also
could be an indication that the Furnace is getting plugged and needs a good
cleaning. Refer to the section in the manual that covers the Daily, Periodic and
Yearly Maintenance of the Furnace.
