Introduction

The entire family of United States Stove Company would like to thank you for purchasing your new pellet burning 

grill. 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 

out of your pellet grill.

THIS GRILL IS DESIGNED FOR THE USE OF PELLETIZED FUEL THAT IS SPECIFICALLY FORMULATED FOR COOKING. THE 

USE OF PELLETS NOT FORMULATED FOR COOKING 

WILL NOT GIVE SATISFACTORY RESULTS.

Use only wood cooking pellets specified by the manufacturer. It is important to use only cooking pellets that 

are 

dry and free from dirt or other impurities. The cooking pellet industry has established standards for wood 

pellet manufacturers. We recommend that cooking pellets used in all U.S. Stove pellet burning grills 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

WARNING: Never leave the 

grill

 unattended while operating. 

Disconnect the 

grill

 from its power source when not in use.

U.S. Stove Company cannot control the quality of cooking pellets you choose to use in your pellet grill and 

assumes no responsibility for that choice.

YOUR GRILL REQUIRES PERIODIC MAINTENANCE AND CLEANING (SEE "MAINTENANCE"). FAILURE TO MAINTAIN 

YOUR GRILL MAY LEAD TO IMPROPER AND/OR UNSAFE OPERATION.

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 grill. 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 Grill. 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 base build up may block air flow through the burn pot, which will significantly affect 

the performance and efficiency of your Pellet Grill. 

INSPECT THE BURNER POT FOR HARD MASS BUILD UP OR 

OTHER BLOCKAGE DAILY. IF NECESSARY, ALLOW THE BURNER POT TO COOL THEN CLEAN THE BURNER POT.

REMOVE ACCUMULATED CREOSOTE OR GREASE TO REDUCE THE RISK OF FIRE. 

When wood pellets are burned 

slowly, they produce tar and other organic vapors that combine with expelled moisture to form creosote. The 

creosote vapors condense in a relatively cool oven flue and exhaust hood of a slow burning fire. As a result 

creosote residue accumulates on the flue lining and exhaust hood. When ignited, creosote makes an extremely 

hot fire.

ASHES SHOULD BE PLACED IN A METAL CONTAINER WITH A TIGHT-FITTIMG LID. THE CLOSED CONTAINER OF ASHES 

SHOULD BE PLACED ON A NON-COMBUSTIBLE FLOOR OR ON THE GROUND, AT LEAST 25 FEET FROM ANY 

COMBUSTIBLE MATERIALS, PENDING FINAL DISPOSAL. WHEN THE ASHES ARE DISPOSED BY BURIAL IN SOIL OR 

OTHERWISE LOCALLY DISPERSED, THE ASHES SHOULD BE RETAINED IN A CLOSED CONTAINER UNTIL ALL CINDERS 

HAVE THOROUGHLY COOLED.

 DO NOT PLACE ANY OTHER WASTE IN THE SAME CONTAINER.

          

 WARNING:

STORE COOKING PELLETS A MINIMUM OF 

3

 FEET (

1

 METER

) AWAY FROM THE PELLET GRILL. 

RADIANT HEAT CAN IGNITE THE FUEL.
