INTRODUCTION
PRODUCT FEATURES
Use only wood cooking pellets specified by the
manufacturer. It is important to use only cooking pellets
that is 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:
Use ONLY pelletized fuel formulated for cooking
Do Not Use Cooking Pellets Labeled as Having
Additives
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
Use only wood pellets formulated for cooking in this
pellet grill.
It is important to note that the ash content of the fuel and
the frequency of operation will determine the frequency
of required cleaning for this pellet grill. A high ash fuel
may result in daily cleaning, while a low ash fuel may
result in less frequent cleaning.
Occasionally, impurities in the fuel will cause a hard mass
build up in the burn pot of this 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 aect the
performance and eciency of this pellet grill. 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 cooking pellets you choose to use in your
pellet grill; U.S. Stove assumes no responsibility for
that choice.
CAUTION: BE SURE TO STORE COOKING PELLETS A
MINIMUM OF 3 FEET (914.5mm) AWAY FROM THE
PELLET GRILL. RADIANT HEAT CAN IGNITE THE
FUEL.

• Creosote-Formation and need for removal. 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, this
creosote makes an extremely hot fire. When grease
or creosote has accumulated, it should be removed to
reduce risk of fire.
• Do not use accessories not specified for use with this
appliance.
• Follow these guidelines to prevent this colorless,
odorless gas from poisoning you, your family or others.
• Know the symptoms of carbon monoxide poisoning:

the blood’s ability to carry oxygen. Low blood oxygen
levels can result in loss of consciousness and death.
• See a doctor if you or others develop cold or flu-like
symptoms while cooking or in the vicinity of this
appliance. Carbon monoxide poisoning, which can
easily be mistaken for a cold or flu, is often detected
too late.
• Alcohol consumption and drug use increase the eects
of carbon monoxide poisoning.
• Carbon monoxide is especially toxic to mother and
child during pregnancy, infants, the elderly, smokers,
and people with blood or circulatory system problems,
such as anemia, or heart disease.

STANDARD USE & OPERATING INSTRUCTIONS
Make sure the grill is always sitting level.
STANDARD STARTUP SEQUENCE
1. Fill the hopper with pellet fuel. Never leave pellets
in the hopper and only use the minimum amount of
pellets needed for cooking. Be sure to close and latch
the hopper lid. Only burn pellet fuel that is specifically
manufactured for use in pellet grills and cookers.
2. Open the grill lid and press the “Power” button. The
three dots between the numbers on the temperature
readout will begin to flash; showing that the grill is in
startup-sequenceinthecorrespondingmode.Thegrill
will automatically light 5 to 8 minutes after pressing
the “Power” button. Remember, start-up times may
vary based on outside ambient temperature and fuel
quality). Prime your auger press the button found on
the control panel labeled “Prime.” When pressed, the
auger spins and feeds pellet fuel to the burn pot. Hold
the “Prime” button in for up to 1 minute to prime the
auger tube with pellets.
NOTE: The startup mode will last approximately 15
minutes. Excessive smoke during startup is typical.
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 can hear a flowing sound
slightly louder than the blower motor of the grill. At
this point, the grill produces significantly less smoke.
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. Each time the lid opens, the
temperature goes down, causing the auger to feed
more. This can lead to potential overcooking of food.
5. Check the actual temperature compared to the set-
point temperature by using the “Display” button
on the control board. The display button helps to
determine when the grill has preheated to the desired
cooking temperature.
NOTE: During the startup, the grill temperature can
exceed the set-point temperature. It is advisable
to keep the display in “Actual” mode to check the
temperature readings and avoid overcooking or
burning. It is easy to tell if the grill is still in startup
by the “Cook” or “Smoke” light blinking. The grills
settings will determine which light blinks.
6. Once the 15 minute startup time is met, and the grill
has reached its set-point temperature, the grill is
ready to have food added.
NOTE: As previously mentioned, keep the lid closed
as much as possible to maintain constant cooking
temperature. The temperature may fluctuate 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 (flavored or not).
Using the “Prime” button may help facilitate a quicker
start-up time.
STANDARD SHUTDOWN SEQUENCE
1. To turn the grill o, make sure the searing station is
o. The light will be o when the searing station is o.
2. Press the power button.
3. The word “Cool” will show on the display, and the grill
will enter a shutdown mode. The blower will continue
to run until it has reached a safe temperature.
NOTE: The “Cook” light will stay solid, and the
“Smoke” light will flash during the shutdown
sequence. Shutdown sequence can take up to 1 hour
depending on the cooking temperature and the outside
temperature.
DO NOT TURN THE GRILL OFF BY UNPLUGGING IT.

OPERATING TIPS
screen.
• When the grill is turned on, there will be three flashing
lights found between the numbers of the display. The
three lights will continue to flash until the grill reaches
180°F, then the startup sequence will be finished.
• Grill operating temperatures are 180°F to 500°F.
• When the grill is first turned on, the control board will
go to 350°F on the first ignition. If the grill has been
used, the control board will go to the last setting used.
• “Smoke” mode ranges from 180°F to 230°F. The
concentration of smoke will vary depending on
the temperature selected. There will be a higher
concentration of smoke at lower settings than there
is when operating at higher temperatures for “Smoke”
mode.
• The combustion blower is on constantly during “Cook”
mode and does not vary in speed.
• If the grill is turned o during “Startup” mode,
everything shuts o without a shutdown sequence.
• If the flame plate is installed improperly, a burn back
may occur due to the airflow restrictions at the burn
pot.
• If the grill is in “Cook” mode and change to “Smoke”
mode, the temperature will automatically go to 180°F.
• If the grill is in “Smoke” mode and change to “Cook”
mode, the temperature will automatically go to 450°F.
• Temperature control doesn’t begin to control the feed
rate for 15 minutes, due to the 15-minute start-up
sequence.
• Make sure to unplug the grill only after it has gone
through the shutdown sequence, cooled o, and is not
in use.
• DO NOT unplug the grill during use or to shorten the
shutdown sequence.
SEARING STATION
• The searing station control is operable from the toggle
switch only (found next to the display board). Only turn
on the searing station for the needed time of use. Make
sure to turn the searing station o 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.
• Using the searing station during general cooking
needs is not recommended, as it can interfere with the
temperature sensor. Only use the searing station to
quickly sear the food and then turn it o. The searing
station takes approximately 5 minutes to reach a
searing temperature during use in the “Cook” settings.
MEAT PROBE
The grills meat probe will track the temperature of the
food as it cooks without having open the grill lid several
times to test the food with an instant-read thermometer.
The correct placement of the meat probe is especially
important when cooking at a higher heat as opposed to
low and slow; because there is such a large dierence
within just one inch of space in the food. When inserting
the meat probe, avoid the bone because it will give
inaccurate readings. After inserting the probe, make sure
it is secured into place. As the thermometer nears its
target temperature, spot-check other areas to see if they
are also close. Be careful, the meat probe and its wires
are hot.
To use the meat probe, first follow the startup
instructions in this manual. Bring the grill up to the
desired temperature. Once preheating is complete, place
the meat onto the grill surface with the probe inserted
into the best section of meat. Plug the meat probe into
the display panel and push the “Display” button until
both the “Actual” and “Setpoint” lights are not lit. The
temperature shown on the display will be the internal
meat temperature. Using the meat probe will prevent
the need of opening and checking the internal meat
temperature, therefore preserving heat and pellet usage.

Fuel other than wood pellets is being
burned in the grill
This pellet grill is designed and tested to use cooking wood pellets. Check
for signs of fuel other than wood pellets. No other types of fuel have been
approved for this pellet grill. If there are signs of other types of fuel being
used, stop using them immediately.
Power surge or brown out situation A power surge, spike, or voltage drop could cause the thermocouple to
malfunction. Use a surge protector
Thermocouple is malfunctioning If the other items check out good, replace the thermocouple.
TROUBLESHOOTING
GRILL FEEDS PELLETS, BUT WILL NOT IGNITE
Possible Causes Possible Remedies (Unplug grill first 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 first when possible)
Power goes out during operation Observe the grill to make certain unsafe burning conditions do not occur
during the outage.
Restarting the unit after a power outage Press the power and the prime button at the same time to resume
standard operation.

TROUBLESHOOTING
GRILL WILL NOT FEED PELLETS
Possible Causes Possible Remedies (Unplug grill first 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 six retaining screws in the service panel. 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 the shaft is removed, inspect it for bent flights, 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 fan.
Bad control board
If the fuse and the wires and connectors check out good, and if 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,
the control board is bad.
