I. Low Fuel Sensor
Thereisalowfuelsensorinthehopperthattellsthecontrol
that the fuel level in the hopper has dropped below the
sensor.Whenthishappens,theLowFuellightontheWall
Controlwillstarttoblink.Youthenknowthatitistimetoll
thehopperwithpellets.
Note:Testing the low fuel sensorcanbedoneby turning
theFEEDADJUSTERknobto“Test”.ThePOWERlightwill
gooffwhenthesensorisuncoveredandwilllightwhenthe
sensoriscoveredagain.
Note: TheLOWFUELlightontheFurnaceControlwilllight
atthesametime.OnlytheLOWFUELlightontheFurnace
Controlwillremainlitforthreeminutesafterthesensoris
coveredwithpellets.SeeNotebelow.
Note: TheLowFuellightindicatesthatthereispowergoing
totheauxiliaryleadsinthecircuitbreakerjunctionbox.(120
VAC60HzMax.1Amp.)Theauxiliarypowerleadscouldbe
usedifabulkhopperandaugersystemwereinstalled.(see
wiringdiagramonpage36)
Type of Fuel
Pelletizedwoodonly.
Note:Thelowertheashcontentofthepelletsmeansless
heatexchangersurfacecleaningthatwillbeneeded.The
cleaner thesesurfaces are kept, the moreefcient the
furnacewillbe.
