SPECIFICATION
PELLET SPECS Pellet Fuels Institute
The Pellet Fuels Institute has designated the
standards listed below for pellets.
Compliance to the standards by pellet
manufacturers is voluntary.

PREMIUM GRADE: Less than 1% inorganic
ash content.

COMMERCIAL GRADE: More than 3%
inorganic ash content.
DIMENSION: Diameter of 1/4 inch to 5/16 inch
LENGTH: Less than or equal to 1.5”.
FINES CONTENT: Not more than 0.5% by
weight; must pass through 1/8-inch screen.
SODIUM ADVISORY: Natural uncontaminated
wood has less than 300 ppm of water-
soluble sodium. Larger amounts may be
found in funnels made from particleboard,
agricultural residues, paper and other
materials, and wood contaminated with salt.

NOTE: Burning of biomass such as wood pellets also emits CO2; however, unless there has been a
change in land use, it is considered that CO2 emitted from biomass is removed from the air by new growth,
and therefore it should not be included as a CO2 contributor.

2015 Heating pellet test results
As you know GLRE Lumber Jack makes 2 premium heating pellets. We have settled on the exact formula and sort the
tree species to get the exact same formula each pellet run and it has paid off for us we are known for consistently
providing the same pellet product batch to batch. Again this year we have tested these formulas for both our Lumber
Jack (Green Bag) blend pellet and our 1st Choice all hardwood pellet.

Your latest test results are as follows:
USR:W215-0806-02-1st Choice hardwood
USR:W215-0806-01-Lumber Jack Blend
