Introduction
The entire family of United States Stove Company thanks you for purchasing your new pellet burning room heater.
At U.S. Stove, we build all of our products with a hands‐on approach to detail and quality. Our old world team of
Craftsmen take great pride in their superior workmanship to ensure you have years of trouble free use of your
pellet heater.
U.S. Stove Pellet Burning Room Heaters have been tested and listed for installation in residential, mobile home
and alcove installations. U.S. Stove Pellet Burning Room Heaters are available in free standing pedestal and
fireplace insert versions.
U.S. Stove Pellet Burning Room Heaters have been certified to:
ASTM E1509‐04, ULC/ORD‐C1482‐M90, ULC‐S627‐00, & ULC‐S628‐00
The performance of your Pellet Stove Room Heater can be affected by the type of pellet fuel you choose to burn in
it. It is important to use only pellet fuel that is dry and free from dirt or other impurities. The Pellet Fuel Industry
has established standards for wood pellet manufacturers. We recommend that pellet fuel used in all U.S. Stove
Pellet Burning Room Heaters meet or exceed the following specifications:
Fines (fine particles): Maximum through a 1/8" screen
Bulk Density: Minimum 40 lbs per cubic foot
Size: Maximum 3/8" Diameter by 1‐1/2" length
Ash Content: 1% Maximum (Premium grade)
3% Maximum (Standard grade)
Moisture Content: 8% Maximum
Heat Content: Minimum 8,200 btu’s per hour
It is important to note that the ash content of the fuel and frequency of operation will determine the frequency of
which you will be required to clean your Pellet Stove. A high ash fuel may result in daily cleaning, while a low ash
content fuel may result in less frequent cleaning.
Occasionally impurities in the fuel will cause a hard mass build up in the burn pot of your Pellet Stove. Impurities
such as silica can virtually form little glass balls when subjected to the high heat generated in the burn pot. When
allowed to collect, a hard bass build up may block air flow through the burn pot, which will significantly affect the
performance and efficiency of your Pellet Stove. It is a good idea to check the burn pot for any hard mass buildup
or other blockage on a daily basis, and if necessary let the burn pot cool and then clean the burn pot.
U.S. Stove Company realizes that it cannot control the quality of pellet fuel you choose to use in your Pellet
heater; U.S. Stove assumes no responsibility for that choice.
CAUTION: BE SURE TO STORE PELLET FUEL A MINIMUM OF 3' (914.5MM) AWAY FROM THE PELLET HEATER.
RADIANT HEAT CAN IGNITE THE FUEL.
Please note that the rating label is located on the inside of the hopper lid on freestanding models and on the
back side of the ash pan cover for insert models.
