This is a state-of-the-art PID
(calculus-based) computer that will keep
your grill at a reasonably steady
temperature with a 150°-550°F range, and
equipped with WiFi Smart Control, dual
meat probes, and a USB charging port.
Prime models run on 12V direct current
(DC), a much safer and optimized power
source that allows for our micro-adjusted
variable speed fan and auger motor for
more precise temp control, greater fuel
economy, and less waste.
12V DIRECT POWER DIGITAL CONTROL BOARDWIFI SMART CONTROL
This micro-adjusted variable speed fan is
located under the hopper and blows air
into the firebox to create initial combustion
and allows for precise temp control.
The Venturi-Style design is lined with
vertical vents creating a burn pot cyclone
of airflow for maximum heat distribution
and complete combustion with minimal
waste. The igniter at the base, ignites the
pellets to start the fire.
COMBUSTION FAN
The sensor sends data to the computer
ten times per second which averages the
readings over slightly longer periods of
time and adjusts the air and pellet flow to
maintain accurate temps in the cavity.

The grease tray slopes downhill from left
to right carrying the drippings from your
food into the grease bucket.
The auger is found at the bottom of the
hopper and feeds pellets into the firebox.

DO NOT over tighten the adjustment rod.
ALWAYS close all lids and doors before starting the grill.
ALWAYS allow the grill to reach 150°F before adjusting the temperature.
ONLY perform these steps on the very first startup
or to fill the auger and recharge the firebox if the
grills runs out of pellets during a cook.

To use this feature, just plug the connector into the receptacle on the front of the
controller.
Lift the stainless flap on the left side of the grill and push the probe through the hole.
Then, insert the probe into the center of the food you are cooking. Press either the
Probe 1 or 2 button to display the temperature of that probe. This process takes a
minute or two to stabilize.
To return to the grill temperature display, simply press the probe button again.
If you do not have the probe installed in the control panel, then your digital
display will read “NFD” (no food) when you press either probe button. The
probe is not suitable for reading temperatures above 257°F (150°C).
The PT200 Platinum Sensor sends data to the computer. This “brain” analyzes the data and adjusts the airflow and pellet
fuel flow to maintain the set temperature. Many things affect the data gathered by the sensor – opening the lid, wind,
grease splatter, humidity, altitude, and gravity (if the grill is not on level ground).
The computer analyzes all the erratic information and averages it over time. Then, it displays the best result as the most
accurate representation of the grill’s current temperature. This is why an instantaneous air temperature reading from a
third-party product does not provide much useful information.
Huffing noises are normal.
The combustion fan, inside the hopper, will turn off and on regularly to provide the
correct amount of oxygen to the fire to maintain the set temperature.
Press the red power button to switch the grill into fan mode. DO NOT unplug the grill or press the power button while it is
in fan mode. Fan mode is important as it not only cools down the grill properly but also blows ash out of the firebox for
your next cook. Once fan mode is complete and the display reads “oFF”, hold down the power button for 7 secs until the
screen goes dark. At this point the grill as successfully powered down. You can leave the grill plugged in for quicker power
up next time or unplug it if you prefer.
Plug in the grill. The display should read “off”. Press
the red power button to turn the unit on. The unit will
go through it’s 0-1-2-3 process and heat up to 150°F.

The beauty starts at the core of the
PRIME series’ 12V Direct Power
design. Direct Current allows for a
micro-adjusted variable speed fan and
auger motor that creates more precise
temp control, greater fuel economy, and
less waste along with increased motor
RPM’s for quicker pellet feed and faster
startups.
The motor turns an auger that feeds
pellets into a firebox. There, an igniter
in the bottom automatically lights the
pellets, and a combustion fan
provides oxygen to start the fire.
The Venturi-Style firebox design is lined
with vertical vents that create a burn
pot cyclone of airflow for maximum heat
distribution and complete combustion
with minimal waste.
The heat shield that covers the firebox distributes the heat to both sides of the grill, flowing up into the convection-style
grill chamber. The thermal sensor mounted inside the grill sends data to the on-board computer ten times every second,
and the digital controller adjusts the air and pellet flow to maintain the temperature you set.
• Clean the grates and grease tray regularly. You can use a wire brush to clean the stainless steel grates. Alternatively,
you can use an old camper’s trick of wadding a piece of aluminum foil and rubbing it lightly on the grates to clean it.
• As with any barbecue, the potential for a grease fire exists. To reduce this possibility, regularly clean the grease tray to
prevent flammable buildup. An easy way to do this is to line the tray with aluminum foil or use our Drip EZ Grease Tray
Liners. Use multiple sheets on the tray and then just peel one off each time you cook. If you are going to line your tray
with aluminum foil, make sure it does not cover the thermal sensor hole on the left.
• Chimney cap. Wipe down the underside of the cap regularly to prevent grease drip.
• Drip system. Make sure the trough where grease drains into the discharge spout is clean and free of debris.
• Place grill on level ground. The grill should be kept as level as possible so that the grease flows into the trough and
out into the bucket and also to insure that the sensor reads evenly, as hot air displaced to one side or the other will
cause irregular operation.
• Clean ash out of the firebox periodically. If ash covers the igniter, the grill may not light. When you clean out the ash
from your firepot, it is not necessary to add in more pellets afterwards. The auger will add in the correct amount of
pellets in the start-up cycle.
• Regularly clean the inside of your grill. Remove grease with hot, soapy water or a grill cleaner. Keep liquids away
from the auger tube and the pellets. Liquids will drain through the bottom hole. Alternatively, just turn the grill on at
500°F for an hour or more to bake off most internal residues.
• Clean the grill lid window. The window will discolor over time. The best way to clean the window is with steel wool.
• Protect your grill. Use a grill cover as much as possible. Water may be able to get in through the hopper in wet
conditions. Make sure to check for wet pellets if your grill gets left out in the rain. As stated, pellets and water do not
mix. Your hopper will, for the most part, stay dry in most weather, but a driving rain may cause adverse results.
• Service? Answers to most common questions can be found on our website greenmountaingrills.com/support.
While you will hopefully have no problems, machinery can fail. Fortunately, each part on the grill is modular, so you can
easily replace one if necessary.
AshVac
Use this method to easily clean out the firebox without removing any internal parts.
Open the ash clean-out door located on the right side of the grill. Place the end of
the vacuum hose over the hole of the clean-out tube that runs into the base of the
burn pot. This will remove most of the excess ash from the firebox.
THIS DOOR MUST BE CLOSED WHEN OPERATING THE GRILL.
Keep the inside of the grill clean using a Shop-Vac. This will take
only a few minutes. Remove the interior parts and vacuum any ash
and residue out of the base of the grill and the firebox.

GREASE FIRE CAUTION
ALWAYS ENSURE THAT THE GRILL IS COLD
AND THE FIRE IS OUT BEFORE CLEANING.

• Smoke Flavor: You will get more smoke flavor at low temperatures than at high ones. If you wish to infuse a piece of
meat with a smoky flavor, cook it at 150°–160°F for an hour or so before you turn up the grill to finish it off.
• Let Meat Rest. Beef, pork, poultry, and fish will generally continue to cook after you remove them from the grill as the
hot outer part of the meat influences the cooler interior. While it seems possible to eat immediately upon finishing your
grilling, that seldom works out as a practical matter. Plan for the internal temperature to rise about 5 degrees after you
take it off the grill. Also, resting allows the juices to redistribute more evenly throughout the meat.
• Spritz! GMG sells a very nice stainless steel spritz bottle for about $10. You will use it on the meats you’re cooking
regularly. Pork butts and picnic roasts, steaks, burgers, chops, and ribs will all benefit from regular, generous spritzing.
A good staple mixture is apple juice plus 2–3 tablespoons of Worcestershire.
• Be Creative! You can cook almost anything on this grill. Try pizza, bread, marinated vegetables, casseroles, and corn
bread, as well as steaks, roasts, hams, pork chops or tenderloins, wild game, fish, and poultry. Cook anything outside in
this appliance that you would cook in your kitchen oven.
• Low Temperature Smoking: For anything you plan to smoke for several hours, we recommend marinating it in sugar
or salt or both, in the refrigerator for several hours beforehand. This will normally cure the meat and should make it
safe. We do not recommend smoking poultry below 185°F for health reasons. Cooking it at or above that temperature
will still impart a rich, smoky flavor.
• General Cooking Guide. If you’re new to pellet grilling, this will help you to get started. These are basic guidelines and
temps/times can vary depending on the size of what you’re cooking, the initial temperature of the food when you put it
in, how often you open the lid, and other variables. ALWAYS COOK MEAT TO A SAFE INTERNAL TEMPERATURE.
RECIPES ARE ONLY GUIDELINES.

GENERAL OPERATING TIPS
• Setting the Temperature: Do not push any buttons until the computer finishes the 0-1-2-3 cycles and automatically
goes to 150°F (66°C). Once it reaches 150°F (66°C), you can change to your desired setting.
• Time to Reach Temperature: It should take about 15–20 minutes from the time you first turn the grill on until it achieves
the temperature you set. Make sure not to adjust the temperature until it reaches 150°F first. Time to heat up will vary
based on the temperature of the climate you live in.
• Temperature Range: You can set the grill as low as 150°F or as high as 550°F.
• Grill Ready: Wait until the grill heats up before cooking. Aside from the soot contained in earlier smokes, the grill will not
cook evenly until it gets hot, just as with a charcoal or gas grill. A slowly blinking light on the digital control panel
indicates that the grill has achieved the target temperature, while no light means the grill is still heating or cooling.
• Heat Distribution: If you are experiencing larger left-to-right temperature discrepancies, the heat shield can be moved
along the belly of the grill left or right to assist with these differences. See our recommended heat shield positioning in
the assembly guide and prefire section.
The grill temperature will climb fairly rapidly. The temperature, however, falls much more slowly. This is because the fire
must be kept going at all costs, which results in a fairly slow fall in inside temperature. Here, too, you can speed the
process by opening the lid to let excess heat escape.
• Controller Functions: In case you have an interest in controller functions, the chart below shows each ignition state
and its function in the 1-2-3 startup cycle.
• During Cycle 0, the controller feeds the right amount of pellets into the firebox. Cycle 1 turns on the igniter. At cycle 2 the
fan turns on, and remains on with the igniter for combustion.
DO NOT INCREASE TEMPERATURE YET.
• The grill needs to make P.O.F (Proof of Fire) which is 5 degrees above ambient temperature. At that point the board will
turn the igniter off and start the auger motor to guide the grill up to 150°F. It is imperative for the grill lid to be closed for
this to happen.
ONCE THE GRILL HAS REACHED 150°F, YOU MAY INCREASE TO YOUR DESIRED TEMPERATURE.
• If there is not a 5° increase within 20 minutes the grill will display FAL. At this point see page 78 of the troubleshooting
section.
• Temperature Variances: The temperature on the digital readout reflects the temperature at the grilling surface on the
left side of the grate where the thermal sensor protrudes into the grill cavity. You may notice differences between the
dome thermometer and the digital readout, depending on the quantity of cold food inside the grill or how often you open
and close the lid or how much wind is present. This is normal.
Please understand that if you cook, for instance, a stand-up chicken, the temperature at the top of the cavity may be
somewhat less than at the grilling surface in the winter and perhaps higher in the summer. You might have decided to
cook the chicken at 275°F, but you notice that the temp on the dome thermometer (if your grill has one) only reads
250°F. Since most of your chicken is well above the cooking surface, you may want to adjust the digital temp of the
grilling surface up to about 300°F to achieve your target cooking temperature of 275°F at the chicken level or vice-versa
if the dome thermometer reads higher.
• Weather: You will likely want to keep your grill out of rain and snow when not in use. In a heavy driving rain, water can
invade the auger tube that will then magically change pellets to sawdust and then expand and dry into something akin to
concrete. This makes for an unpleasant repair. Melting snow can also cause the same problem. A grill cover will clearly
help the situation, but the garage seems more foolproof.
• Grilling in Various Temperatures: Because we know that you will use the grill in a variety of weather conditions, we
tend to overshoot the initial default temperature of 150°F by 20–25 degrees on warm days. We do this so that it does
not take interminably long on a cold day to reach its target temperature. The grill will eventually cool back down to 150°F
on its own, or you may speed the process by simply opening the lid to let out excess heat.
Once your outside temperatures drop below 35°F (2°C), the Turbo mode kicks in to accelerate the volume of pellets and
air so that you do not have to wait so long for the grill to heat up as you otherwise would without it.
• Thermal Blanket: Tests from users have indicated that you can reduce your pellet consumption by 40%–50% in very
cold weather by using a GMG thermal blanket. If you grill regularly in cold weather, this investment will likely pay off
handsomely. Do not use the thermal blanket in the summertime, as it provides no noticeable benefit and may actually
work against you on very warm days.
• Keep the Lid Closed When Cooking. The grill cooks with convection heat, so an open lid only dissipates heat into the
atmosphere. “If you’re lookin’, you’re not cookin’.”
• Pellet Checking: Be sure to keep pellets in the hopper! Check your hopper occasionally so that your grill does not go
out in the middle of cooking your meal.
• Pellet Storage: Store your pellets in a cool, dry place. Do not allow them to get wet, as they will turn back into sawdust.
• Bypass Mode for Hot Restarts: Occasionally, you may experience a power outage while the grill is in use, or someone
accidentally turns the grill off, or you undercook something and want to resume cooking for a little longer.
ONLY use this procedure if power is lost and a fire is still in the grill or for testing parts.
Use this method if you still have some fire left in the firebox, which is usually no longer than about 6–7 minutes later. If
you have run the fan mode for more than about 3–4 minutes, this will not work.
If necessary, make sure the grill is plugged in first. When the digital readout displays off, press the red power button to
turn the grill back on. Once the display reads “0” hold the power button for approximately 7 seconds, or until the digital
readout displays a temperature. Now adjust the temperature to your desired setting.
• Powering Down: Simply press the red power button and your grill will automatically go into fan mode. Allow fan mode to
complete which takes about 15 mins. Once the fan mode is complete the display will read “oFF” and you can press and
hold the power button for about 7 secs until the display goes dark, at which point the grill has successfully powered
down. You can leave the grill plugged in for easier power up of your next cook or unplug it if you prefer.

TROUBLESHOOTING
Grill doesn’t turn on when you press the power button.
Check to make sure the power cord is plugged in. When the AC adapter is plugged into the wall, check that the
light on the adapter comes on.
Inspect both ends of the male-to-male power cord to ensure the connections aren't compromised.
Check the circuit breaker and/or GFCI on the circuit the adapter is plugged into. Plug a small appliance into the
same outlet to see if you have electricity.
Unplug the grill. Remove the control panel. Check for loose wires connected to the wiring harness. Disconnect and
reconnect the wiring harness to ensure a secure connection.
Grill doesn’t come up to temperature.
If grill remains at ambient temperature...
Check the firebox to see if it has overflowed with pellets. If it has, clean it out and start over. This overfill can result
from turning the grill off without using the fan mode or from charging the firebox when it does not need to be
charged. Reread the section on “Priming the Firebox” to understand that. You only need to prime the firebox the
first time you use the grill or on any subsequent occasions when it runs out of pellets and the auger runs until
empty.
If grill lights, but does not reach set temperature...
Check the combustion fan to ensure it spins freely and there is no damage to the blades.
Ensure the heat shield is properly installed.
Erratic temperature.
If the digital display reads “SEN” or shows rapid fluctuation in temperature (faster than the grill could realistically
increase/decrease its internal temperature) call our technical support 530-347-9167 opt. 1.
Otherwise, check to make sure you do not have aluminum foil on the grease tray that is blocking the thermal
sensor. It is okay to wrap your tray in foil. However it must be wrapped tight to the metal, and the hole as well as
the half-moon cutout must be punched out of the foil to ensure proper airflow.
A simple way to check the thermal sensor is to look at the initial temperature reading the grill gives after the
0-1-2-3 start-up process. This temperature should be close to the ambient air temperature since the grill has not
yet had a chance to heat up.
Improper shield placement will result in issues coming to temperature. When using the heat shield adjustment rod,
a centered heat shield should be positioned approximately at the “0” mark on the rod. The depth to which the rod is
threaded into the receiving nut varies, so some experimenting might be needed to find the perfectly adjusted “0”
point on your rod.
Ensure the grease tray is installed correctly. See the previous page for proper installation.
Smoke is coming out of the hopper.
Make sure your burn pot is empty of ash and pellets.
Make sure the hopper lid stays closed when you have the grill on. Press firmly down on each of the corners of the
lid to make certain it is closed tight. If a corner of the lid sits up even 1/8 inch while the lid is flat, a warped hopper
lid is your issue.
You can test this by running 2 sheets of tin foil over your hopper then closing the lid down on top of the foil to make
a temporary seal, hopefully preventing smoke from traveling through your hopper.
Ensure the combustion fan spins freely and is not damaged.
Ensure the pellet dump door is closed tight.
If all else fails, the square gasket seal between the hopper and auger may be the culprit. You can seal with
high-temp silicone.
Low pellet alarm beeps continuously.
Fill the hopper with pellets so that their level is above the low pellet sensor. If this does not solve the problem,
unplug the grill then disconnect the alarm from and reconnect it to the back of the control panel. If the beeping
persists, your alarm is broken and needs to be replaced. Contact our technical support 530-347-9167 opt. 1. In the
meantime, you can stop the beeping by unplugging the low pellet alarm from the circuit board and leaving it
disconnected.
*The low pellet alarm is not necessary for the grill’s functionality. You can leave the alarm disconnected and
continue cooking.
Ensure the grease tray is installed correctly.
Improper shield placement will result in issues coming to
temperature. When using the heat shield adjustment rod,
a centered heat shield should be positioned approximately
at the “-0.5” mark on the rod. The depth to which the rod is
threaded into the receiving nut varies, so some
experimenting might be needed to find the perfectly
adjusted center point on your rod.

TROUBLESHOOTING
No pellets in the firebox.
Assuming that you’ve charged the firebox so that there are pellets in the auger tube, turn the grill on and press the
power button to send the control to cycle 0. Examine the auger bit through the firebox to see if it’s turning.
If it is and there aren’t any pellets coming through, they are bridged up over the auger’s intake. Turn the grill off, sift
the pellets around inside the hopper, and put the grill back into cycle 0. Wait until the pellets emerge into the
firebox. It may take up to 2 full cycle 0’s to get pellets all the way through the auger tube. Once they emerge, turn
the grill off and start it again all the way through the 0-1-2-3 cycles to fire it up.
It may take more if the auger is not turning. Listen for the auger motor. If the auger motor is engaged and the auger
bit is not turning, then there is a broken linkage between the motor and the auger shaft. Call technical support on
530-347-9167, opt. 1.
I have uneven heating.
Uneven heat can be corrected by making small adjustments to your heat shield placement. Try sliding the shield
toward the hot side in ¼ inch increments while taking note of the temperature changes. Using the Heat shield
adjustment rod, a centered heat shield should be positioned approximately at the “0” mark on the rod. The depth to
which the rod is threaded into the receiving nut varies, so some experimenting might be needed to find the
perfectly adjusted “0” point on your rod. Once you find the best heat shield placement, we encourage you to mark
that distance on the heat shield adjustment rod. That way, you can subsequently repeat the positioning whenever
the grill is relocated or the burn pot is cleared internally.
Loud clicking sound when the auger is running.
This is typically the sound of a stripped/slipping gear within the auger’s gearbox. Auger assembly replacement will
be needed.
Grill didn’t light (FAL message).
There may be too much ash in the firebox. Wait until it cools off, and clean out the ash. Alternatively, pellets may
have overfilled the firebox. Never turn the grill off and on repeatedly as this will overfill the firebox with pellets. Each
time the grill displays “0” on start-up, it feeds a full load of pellets into the burn pot. The igniter won't light the pellets
unless air can flow freely through the combustion chamber.
The combustion fan may not have been operating. Check to make sure that the fan blades turn freely and the fan
runs on cycles 2 and 3 of the 0-1-2-3 sequence.
The auger might not have turned pellets into the burn pot. Refer to “No pellets in the firebox” above.
If there isn’t any ash or pellet buildup, the fan works properly, and fresh pellets are feeding in, your igniter is most
likely out and the grill will require a replacement.
*The grill can be manually lit if the igniter is out. Charge the burn pot with a handful of pellets, and light them with a
propane torch or. Once the pellets are able to maintain a flame by themselves, plug the grill in so it displays “off.”
Hold the “power” button for 10 seconds. The grill will initially display “0” but then skip to a temperature reading
while turning on the fan and auger. Let the grill come to 150 then select your grilling temperature like normal.
Auger is jamming.
Turn the grill into cycle 0 by pressing the “power” button (first stage of the normal start-up procedure), and listen for
the auger motor. If the motor engages, look inside your burn pot toward the end of the auger bit to determine if the
auger is spinning. If the auger is spinning but you don’t have pellets feeding into the burn pot, you have pellets
bridged up over the intake of the auger tube. Turn the grill off, sift the pellets around inside the hopper, and put the
grill back into cycle 0. Wait until the pellets emerge into the firebox. It may take up to 2 full cycle 0’s to get pellets
all the way through the auger tube.
If you have determined that your auger does not turn when the auger motor is engaged, you can try to work the
affected pellets through the auger tube to clear out the jam. Remove the grease tray and heat shield from the body
of the grill. Remove all the pellets from the hopper and the firebox.
Once the auger tube is clear, you will need to refill it with fresh pellets by running cycle 0 a few more times after the
hopper has been filled. Once you see fresh pellets coming out, turn off the grill and start it up again through the
entire 0-1-2-3 process with the heat shield and grease tray installed.
Combustion fan doesn’t seem to be working properly.
There’s no need for concern if your fan is not blowing at a constant speed. It will run at many RPMs in order to
maintain the most stable temperature.
The fan should run continuously from cycle 2 on start-up until the grill completes the fan mode.
First, unplug the grill. Then, using your finger, flick the fan to make sure it spins freely and does not appear to have
any visible damage. If there is any damage to the blades, your grill will require a new combustion fan.
Check the wires leading to the combustion fan to make sure those connections are secure and undamaged.
