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 (ne 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
-2-
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.

PREPARING TO USE YOUR GRILL
Important: You must season the grill before cooking any food on your grill for the first time. The unit must be
operated at maximum temperature for 1 hour with the lid closed. This allows any oil residue from the manufacturing
process to burn off and also allows the high temperature paint to cure.
Avoid placing any items on the unit during this period as the paint could be permanently damaged.

WARNING: Never leave the grill unattended while operating.
Disconnect the grill from its power source when not in use.
WARNING: DO NOT TOUCH THE AUGER

Standard Use Operating Instructions
Always make certain that the grill is setting level or is slightly tilted towards the drip bucket.
STANDARD STARTUP SEQUENCE
1. Fill the hopper with pellets. Be sure to close and latch the hopper lid. Burn only pellets that are specically
manufactured for use in pellet grills and cookers. Never leave pellets in the hopper. Only use the amount of
pellets needed to cook for any given time.
2. Open the grill lid and press the “Power” button. The “Cook” or “Smoke” mode lights will begin to ash
indicating that the grill is in its startup sequence in the respective mode. The grill will automatically light 5 to 8
minutes after pressing the “Power” button (start-up times may vary based on outside ambient temperature
and fuel quality). To prime the auger press the button located on the control panel labeled “Prime”, when
pressed it causes the auger to spin and feed pellets to the burnpot. The “Prime” button can be held in for up
to 1 minute to prime the auger tube with pellets.
NOTE: The startup mode will last approximately 15 minutes. It is normal for the grill to smoke excessively during
startup.
3. Set the control board to the desired cooking temperature using the “Cook Temp” buttons on the control
board. Temperature settings are in 5°F increments.
4. Once the grill ignites, you will hear a owing sound slightly louder than the blower motors of the grill. You
should also notice a signicant reduction in the amount of smoke being produced. Close the grill lid once
ignition has occurred.
NOTE: Allow the grill lid to remain closed during the pre-heat and as much as possible during cook time. Feed
rates during run mode are determined by temperature readings, so each time the lid is opened, the temperature
goes down, and thus, the auger feeds more. This can lead to potential overcooking of food.
5. You can easily check the actual temperature compared to the set-point temperature by using the “Display”
button on the control board. This allows you to determine when the grill has preheated to your desired
cooking temperature.
NOTE: During the startup, the grill temperature can exceed the set-point temperature. So, it is recommended that
you leave the display in “Actual” to monitor the temperature readings and avoid overcooking or burning. You
can easily tell if the grill is still in startup by the “Cook” or “Smoke” light blinking (depending on which mode you
have the grill set).
6. When startup time (15 minutes) has been met and the grill has reached its set-point temperature, you are
now ready to add food.
NOTE: As previously mentioned, keep lid closed as much as possible to maintain constant cooking temperature.
Temperature may uctuate slightly.
NOTICE !! During operation, the technology in this grill’s programming learns the fuel rate needed to sustain the
selected cooking temperature. Therefore, start-up times may vary based on outside ambient temperature and
fuel quality or type (avored or not). Using the Prime button may help facilitate a quicker start-up time.

•If you turn the grill off during “Startup” Mode, everything shuts off without a shutdown sequence.
•If the ame plate is installed improperly, a burn back may occur due to the airow restrictions at the burnpot.
• If you are in “Cook” mode and change to “Smoke” mode, the temperature will automatically go to 295°.
• If you are in “Smoke” mode and change to “Cook” mode, the temperature will automatically go to 300°.
• Temperature control doesn’t begin to read and control feed rate for 15 minutes, due to the 15 minute start
up sequence.
•Make sure to unplug your grill only after it has gone through the shutdown sequence, cooled off, and is not
in use.
•DO NOT unplug your grill during use or to shorten the shutdown sequence.
SEARING STATION
• The searing station control is operable from the toggle switch only (located next to the display board). Only
turn on the searing station for the needed time of use. Make sure to turn the searing station off when not in
use. The searing station will function even if the grill is not in operation. Always unplug the grill when not in
use.
• It is not recommend using the searing station during your general cooking needs, as it can interfere with the
temperature sensor. Only use the searing station to quickly sear your food and then turn it off. The searing
station takes approximately 5 minutes to reach a searing temperature during use in the grill “cook” settings.
SHUTDOWN SEQUENCE
1. When you are ready to turn the grill off, make sure the searing station is off. The light will be off when the
searing station is off.
2. Press the “Power” button.
3. The display will go blank and the grill will enter a shutdown mode. During the shutdown mode the blower
will continue to run until the grill has reached a safe temperature.
NOTE: The “Cook” light will remain solid and the “Smoke” light will flash during this sequence.
The Shutdown sequence can take up to 1 hr depending on the cook temperature and the outside temperature.

MEAT PROBE
This grill is equipped with a meat probe. When plugged in, the meat probe allows you to track the temperature
of the food as it cooks without having to repeatedly open the grill lid and test with an instant-read thermometer.
Proper placement is particularly important when cooking at higher heat as opposed to low and slow, because
there will be a large differential within just an inch of space in the food. When inserting the meat probe avoid
bone as this will give incorrect readings.
When placing the probe, make sure it is secure. When the thermometer nears the target temperature, spot-
check other areas to see if they are also close. When handling the meat probe be careful to remember that the
probe and its wires are hot.
To utilize your meat probe, first follow the start up instructions. Bring your grill up to the temperature you desire
to cook. Once preheating is complete, place your meat on the grill surface with the probe inserted in the
optimal place in the roast. Plug the meat probe in on the display panel. Push the DISPLAY button until both
the “Actual” and “Setpoint” lights are not lit. The temperature shown on the display will be your internal
meat temperature. The use of the meat probe will prevent you from opening and checking the internal meat
temperature, therefore preserving heat and pellet usage.
Note: These are suggested approximations only and intended as guidelines only. For best results please follow
appropriate recipe.

Troubleshooting
GRILL FEEDS PELLETS, BUT WILL NOT IGNITE
Possible Causes Possible Remedies (Unplug grill rst when possible)
Bad igniter element.
Put power directly to the igniter element. Watch the tip of the
igniter from the front of the grill. After about 2 minutes the tip
should glow. If it does not, the element is bad.
The control board is not sending power to the igniter.
Check the voltage going to the igniter during startup. It should
be 110-115 volts. If the voltage is lower than full voltage, check
the wiring. If the wiring checks out good, the board could be
bad.
POWER FAILURE DURING USE
Possible Causes Possible Remedies (Unplug grill rst when possible)
Power goes out during operation. Observe the grill to make certain unsafe burning conditions do
not occur during the outage.
To restart unit after power outage. Press the power and the prime button at the same time to
resume standard operation.
GRILL WILL NOT FEED PELLETS
Possible Causes Possible Remedies (Unplug grill rst when possible)
Thermocouple is defective.
Wait for the grill to cool for about 30 - 45 minutes. Check the
thermocouple to see if it’s bad. Check resistance with volt
meter.
Bad Auger Motor.
Remove the two retaining screws in the service panel and
swing out of the way. Remove the auger motor from the auger
shaft and try to run the unit. If the motor will turn, the shaft is
jammed on something. If the motor will not turn, the motor is
bad.
Auger Jam.
Start by emptying the hopper. Then remove the auger motor
by removing the auger pin. Remove the two screws holding
the auger bushing. Gently pull the auger shaft straight out so
that the end of the auger shaft comes out. After you have
removed the shaft, inspect it for bent ights, burrs, or broken
welds. Remove any foreign material that might have caused
the jam. Also, check the auger tube for signs of damage such
as burrs, rough spots, or grooves cut into the metal that could
have caused a jam.
Loose wire or connector. Check all wires and connectors that connect to the auger
motor, thermocouple, and the fan.
Bad control board.
If the fuse is good, the wires and connectors check out good,
and the high limit switch did not trip, test for power going to
the auger motor. If there is not a full current going to the auger
motor when the fuel feed light is on, you have a bad control
board.
