Fuel quality is important, please read the following:
Your Enviro pellet stove has been designed to burn ¼” (6mm) dia wood pellets and other 

organic fuels. DO NOT use this appliance as an incinerator. DO NOT use unsuitable and non 

recommended fuels, including liquid fuels 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 fuel being 

burned. As the heat output of various quality fuels differs, so will the performance and heat 

output of the pellet stove.
CAUTION:
 It is important to select and use only fuel 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.
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 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. 
FUEL FEED RATES: Due to different fuel densities and sizes, fuel feed rates may vary.  This may require 

an adjustment to the slider damper setting or to the auger feed trim setting.
Since Sherwood Industries Ltd. has no control over the quality of fuel that you use, we assume no liability 

for your choice in fuels.
FILLING FUEL HOPPER: Open lid on top of unit, check hopper for foreign objects, empty the bag into 

the hopper, and ensure hopper lid closes completely.
Store fuels in a dry location at least 36” (1 m) away from the pellet stove, and clear of the 

space required for charging and ash removal.  
WARNING: Parts of the appliance, especially the external surfaces, will be hot to touch 

when in operation so use due care.
FLAMMABLE LIQUIDS:
  Never  use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter 

fluid, or similar liquids to start or “freshen up” a fire in the heater.  Keep all such liquids well away from 

the heater while it is in use.
