PELLET QUALITY IS IMPORTANT, PLEASE READ
YOUR ENVIRO PELLET STOVE HAS BEEN DESIGNED TO BURN WOOD PELLETS ONLY. DO
NOT USE ANY OTHER TYPE OF FUEL, AS THIS WILL VOID ANY WARRANTIES STATED IN
THIS MANUAL.
CAUTION: It is important to select and use only pellets that are dry and free of dirt or any impurities such as high
salt content. Dirty fuel will adversely affect the operation and performance of the unit and will void the warranty.
The Pellet Fuel Industries (P.F.I.) has established standards for wood pellet manufactures. We recommend the use
of pellets that meet or exceed these standards. Ask your dealer for a recommended pellet type.
THE PERFORMANCE OF YOUR PELLET STOVE IS GREATLY AFFECTED BY THE TYPE AND QUALITY OF WOOD
PELLETS BEING BURNED. AS THE HEAT OUTPUT OF VARIOUS QUALITY WOOD PELLETS DIFFERS, SO WILL THE
PERFORMANCE AND HEAT OUTPUT OF THE PELLET STOVE.
Since Sherwood Industries Ltd. has no control over the quality of pellets that you use, we assume no liability for
your choice in wood pellets.
P.F.I. PELLET STANDARDS:
Fines (fine particles)......1% maximum through a 1/8” screen
Bulk Density..................40 lbs. per cubic foot minimum
Size..............................1/4” to 5/16” diameter 1/2 – 1-1/2” long maximum
Ash Content..................1% maximum (Premium grade)
.................3% maximum (Standard grade)
Moisture Content...........8% maximum
Heat Content.................approximately 8200 BTU per lb. minimum
ASH: The ash content of the fuel and operation of your stove will directly determine the frequency of cleaning. The
use of high ash fuels may result in the stove needing to be cleaned daily. A low ash fuel may allow longer intervals
between cleaning.
CLINKERING: [clinkers are silica (sand) or other impurities in the fuel that will form a hard mass during the
burning process]. This hard mass will block the air flow through the Burn Pot Liner and affect the performance of
the stove. Any fuel, even approved types may tend to clinker. Check the Burn-Pot Liner daily to ensure that the
holes are not blocked with clinkers. If they become blocked, remove the liner (when the unit is cold) and clean/
scrape the clinkers out. Clean the holes with a small pointed object if required. Refer to the section Routine
Cleaning and Maintenance.
PELLET FEED RATES: Due to different fuel densities and sizes, pellet feed rates may vary. This may require an
adjustment to the slider damper setting or to the auger feed trim setting on Low.
Store pellets at least 36” (1 m) away from the pellet stove.
