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.
