Fuel and Fuel Storage
Pellet fuel quality can uctuate from manufacturer to
manufacturer,andevenfrombagtobag.
Hearth&HomeTechnologiesrecommendsusingonlyfuel
thatiscertiedbythePelletFuelsInstitute(PFI).
FuelMaterial
• Madefromsawdustand/orotherwoodby-products
• Sourcematerialtypicallydeterminesashcontent
HigherAshContentMaterial
• Hardwoodswithhighmineralcontent
• Barkandleavesassourcematerial
• “Standard”gradepelletsandotherbio-mass
LowerAshContentMaterial
• Softwood;pine,r,etc.
• Materialswithlowermineralcontent
• “Premium”gradepellets
Clinkers
Minerals and other non-combustible materials, like sand,
willturnintoahardglass-likesubstancewhenheated.
Treesfromdifferentareaswillvaryinmineralcontent.For
this reason, some fuels will produce more clinkers than
others.
Moisture
Always burn dry fuel. Burning fuel with high moisture
contenttakesenergytodryandtendstocooltheappliance
thus,robbingheatfromyourhome.Damppelletfuelcould
turnbackintosawdustwhichdoesnotowproperlythrough
thefeedsystem.
Size
• Pellets are either 1/4 inch or 5/16 inch (6-8mm) in
diameter
• Lengthshouldbenomorethan1-1/2inches(38mm)
• Pellet length can vary from lot to lot from the same
manufacturer
Performance
• Higherashcontentrequiresmorefrequentmaintenance.
• “Premium” grade pellets will produce the highest heat
output.
• Burning pellets longer than 1-1/2 inches (38mm) can
causeinconsistentfeedingand/orignition.
Werecommendthatyoubuyfuelinmulti-tonlotswhenever
possible. However, we do recommend trying different
brands prior to purchasing multi-ton lots, to ensure your
satisfaction.
CAUTION! Tested and approved for use with wood pellets
ONLY.Burningofanyotherfuelwillvoidyourwarranty.
When changing from “Premium” grade pellets to a
“Standard”or“Economy”gradefuel,theFEEDADJUSTER
will likely need adjusted to a lower setting. When under
maximumdemand,ensurethereisnounburnedfuelbeing
pushedintotheashpan.
Storage
• Woodpelletsshouldbeleftintheiroriginalsealedbag
untilreadytouse,topreventmoisture.
• Donotstorefuelwithinthespeciedclearanceareas,or
inalocationthatwillinterferewithroutinecleaningand
maintenanceprocedures.
