Position your heat shield so the “V” on the bottom is centered over the firepot. This piece will split your rising heat left and right, so proper placement is crucial.
If your grill seems to run hotter than what it displays, or if it has a hot right side, move your heat shield further to the right. If the grill is running cooler, move it to the left. A general rule is half an inch for every 50 degrees of difference you experience. Once the perfect placement is achieved, measure the shields distance to the left wall of the grill for future reference.
- The bottom tray has the half moon cut out that wraps around the thermal sensor on the left. The top tray has two handles on either end, and sits flush against the bottom tray, sliding left and right to open and close the holes.
- Here, you can see the correct positioning of the bottom portion of the two part grease tray with the half moon cut out to the left around the thermal sensor.
- This grease tray system was designed so the top tray can move left and right to open and close the holes. For indirect heating you will want the holes closed, this is best for temperatures 350 degrees or less. If you want to sear your meat you will want to have the holes open, allowing direct heat to your meat.
- You can use aluminum foil with this system, we recommend wrapping the top tray.
- Angle the grease tray and insert it down into the grill. Be sure that the side with the finger hole is on the left.
- The right side of the tray needs to hang over the grease trough shown in the picture.
- The left side of the tray (side with the hole) has a flange on it that fits over the mounted bracket on the left side of the grill. (Note: Be sure that the grease tray is not touching the thermal sensor located inside the grill on the left wall. If you choose to cover your tray in foil, be sure that both the thermal sensor and the hole in the grease tray are not obstructed with foil.)
We use two finger widths as a general rule for cap height. If you are experiencing any temperature or combustion related issues, raise your cap up all the way to give your grill enough space to release exhaust.
To adjust, loosen nut at base of the screw, then adjust the nut on the top of the chimney cap either up or down. Tighten set screw to secure in place.
After every cook, drop the temp to 150 degrees on the digital readout, then press the down arrow one more time. The LCD screen will read “fan” and run a timed cycle to blow out all the excess ash. Once the fan cycle is complete the grill will display “off” and is ready to be used again.
You will need to periodically clean out the burn pot for the grill to run efficiently. A general rule is to clear any ash from the pot after every bag of pellets you burn.
- Line up hinge pegs on the tray with the hinge receivers attached to the right side of the grill. (See photo)
- Secure table into brackets, then lift tray up and attach the support arm.
- Push down abruptly on the top of the tray to snap into place.
Hang the grease bucket on the hook underneath the side tray table on the right. If you like, you may line the grease bucket with foil for easy cleaning.
To install the chimney you will need a 10mm wrench or socket. Tighten the chimney securely to the side of the grill. Make sure that the gasket goes between the chimney and the grill itself.

Your grill’s password is the grill’s serial number found on the green plate located on back of your grill. It should be 8 characters.
First confirm the grill is plugged in and has power. The grill display should read “off”.
In order to connect via WiFi Mode you must first establish a point-to-point connection to your grill’s network. See the previous section on how to connect via point-to-point.
Track the internal temp of your food with our dual meat probes. Monitor multiple meats at the same time or if you’re cooking a large cut of meat, keep track of outer and inner temps simultaneously.
Grill is off.
Fan Mode is on.
Grill is attempting to update.It will count from 0-100 and either display SUC for a successful update or FAL for update failure. See the FAL section below for more info.
Updates were successful.
Ignition Failure or Firmware Update Failure:
If you see the FAL code displayed shortly after turning the grill on you are experiencing an Ignition Failure which can be due to one of the following situations:
- Firebox is overloaded with pellets or ash. Remove the internal components and clean out the firebox completely.
- The auger is not feeding clean dry pellets into firebox during cycle 0. Once the internal parts are removed and firebox is cleaned out, turn the grill on and wait to verify that pellets are being properly fed through the auger tube and into the firebox.
- Heat shield is installed incorrectly. Reference the proper heat shield installation section under Assembly/Setup.
- Grease tray is installed incorrectly. ALWAYS make sure the hole is on the left near the thermal sensor and the half moon cut-out is on the right going into the grease trough.
- If steps 1-4 have been confirmed you may have a faulty igniter that needs to be replaced.
Firmware Update Failure:
This can be due to one of two things:
- The network and/or password is incorrect. Make sure to correctly input the network and password. It is case sensitive.
- Your grill is too far away from your router. Try to make sure it is within 20 feet of your router.
No Food Found. This can be due to the food probe not being completed inserted into the control board. Make sure the probe is securely inserted into the control board. If you’re still seeing NFD you may have a faulty food probe which can be replaced.
While all bbq’s have hotspots, GMG gives you some control over your heat distribution through the adjustable heat shield technology. Majority of bbq’s tend to have hot spots. Don’t worry, we’ve made it very easy to correct this even mid-cook. The heat distribution can be corrected by making small adjustments to your heat shield placement with the external adjustment handle.
GENERAL RULE OF THUMB: If your grill seems to run hotter on the right side, slightly adjust your heat shield to the right and vice versa. Generally a quarter an inch adjustment can create a 50° difference. 4.25 in. from the left wall is the sweet spot to start out at which should align the right outside grill wall with the -0.5 mark on the adjustment handle. Keep in mind this is a starting position, environmental factors like ground levelness, alltitude, humidity, etc play a role in the way heat distributes through your grill. Fortunately the adjustable technology allows you to customize your heat distribution to what works best for you.
PRO TIP:Once you find the best heat shield placement for your grill, we encourage you to measure the distance from the shield to the left wall of the grill, that way you can repeat that positioning after every time the grill is relocated or parts are removed for cleaning.
Possible causes (you may see an FAL code display on control board screen when this occurs):
- There could be too much ash in the firebox. ALWAYS make sure the grill is cool before removing any internal parts. Remove the parts and clean out the firebox of all ash and/or pellets.
- Pellets may have overfilled the firebox. Never turn the grill off and on repeatedly, as this will fill the firebox with pellets. The igniter cannot light the pellets unless air can flow freely through the combustion chamber.
- Combustion fan is not operating correctly. Check the fan located underneath the hopper to make sure the fan blades turn freely and that it runs on cycle 2 of the 0-1- 2-3 sequence. If the fan is not turning on in cycle 2 it may need to be replaced.
- The auger is not feeding pellets into the firebox. Make sure you grill is off and cooled off. Remove the internal parts, make sure the firebox is cleared and turn it back on. Check to see if pellets are feeding through the auger tube during cycle 0. If they’re not you may have a jammed auger. Refer to the “My auger is jammed” section below.
- If there is no ash buildup, the fans work properly, and fresh pellets are feeding in, your igniter is out and the grill will require a replacement igniter.
No worries, you probably just need to refill your hopper with pellets. If the hopper is full and the alarm is still beeping, you can disconnect and reconnect the alarm from the back of the control panel. If the beeping persists, your alarm is broken and can be replaced.
NOTE: The low pellet alarm is not necessary for the grills functionality. You can leave the Alarm disconnected and continue cooking with no issues.
If you using charcoal pellets or very dark colored wood pellets, this can
When your grill goes through its startup process, it is not unusual to see a great deal of smoke especially when the fans start the fire. Once you reach the default temperature of 150 degrees, you are in a smoke setting. Traditional smoke settings will go up to 225 degrees. In this range of temperatures, you will see a steady flow of smoke as the grill is feeding more pellets into the firebox at the loss of temperature. As your grill is maintaining temps, you will not see as much smoke. As you increase the temperature controller above 225 all the way up to 550 degrees, you will see even less smoke as you reach into barbecue temperatures, due to the high flame.
Note: Generally, you get more smoke at lower temps than at high ones. That being said, pellets burn extremely efficiently because of their shape and density, so they will not produce as much smoke as a stick burner.
This can be due to a few things. ALWAYS make sure your grill is powered down and cooled off before checking internal parts.
The GMG hopper box is pressurized for both safety and performance. This positive pressure should prevent any burn back from going back through the auger and into the hopper as long as the lid is closed. If the lid closed and you’re still receiving smoke into the hopper it could be due to:
- Make sure the hopper lid is closed tightly on all 4 corners. If a corner of the lid sits up even 1/8 in. while the lid is flat, a warped hopper lid is your issue and should be replaced.
- Make sure the chimney cap is raised to the maximum height as the grill needs proper airflow and positive pressure out through the chimney.
- Make sure the grease tray is installed correctly with the hole on the left
- Clean out your pellet hopper. Saw dust can accumulate at the bottom of the hopper blocking the positive pressure vents.
- If you’re using any after market products, make sure they are not disrupting the positive pressure airflow.
- Ensure the pellet dump and AshVac doors are closed tightly as this ensures proper airflow.
- If all else fails, the square gasket seal between the hopper and auger may be the culprit. You can seal with high-temp silicone.
This can be due to a few things. First there are 4 different points of connection from the outlet to you grill. Make sure each is securely fastened.
If all connections are secure you may need to check your power source. It is possible your GFCI or breaker has tripped, cutting power to the grill.
If you confirm power to the outlet, it’s time to check out the control panel on your grill. ALWAYS MAKE SURE YOU UNPLUG YOUR GRILL before you start looking over any parts.
- Unscrew the 2 hexabolts on the front control panel and pull the panel out towards you. You may let the panel hang.
- Take a look on the back of the “Power” button and make sure the wire clips have not come loose.
If this hasn’t solved your issue you will need to check the fuse.
- One of the red wires coming from the main plug on the control board has a black fuse holder.
- Using two hands rotate the fuse holder counter clockwise until it opens.
- Inspect that the fuse is not burnt, broken, and that the filament is intact.
At times, the wires underneath your hopper assembly will shift and block your combustion fan. Take a look underneath your grill for a wire obstruction and simply move it away from your combustion fan blade. This will end the clicking noise.
If your grill is making a clicking noise and the auger does not run, most likely there is a stripped gear in the gearbox, and the auger motor will have to be replaced.
