Q
UALITY
:
Pellet quality is important, please read the following:
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.
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.
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
manufacturers. We recommend the use of pellets that meet or exceed these standards. Ask your dealer
for a recommended pellet type.
P.F.I. PELLET STANDARDS:
Fines (fine particles)......1% maximum through a 1/8” screen
Bulk Density..................40 pound per cubic foot minimum
Size..............................1⁄4” to 5/16” diameter 1⁄2 – 11⁄2” long maximum
Ash Content..................1% maximum (Premium grade)
..................3% maximum (Standard grade)
Moisture Content...........8% maximum
Heat Content.................approximately 8200 Btu per pound 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.
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.
Store pellets at least 36” (1 m) away from the pellet stove.
