ALWAYS keep the entire grill a minimum of 48″ from all combustibles.
DO NOT use in any enclosed area or any area without adequate ventilation.
IMPORTANT: DO NOT OVER TIGHTEN the adjuster handle when installing. For proper heat shield positioning, use the marks on the handle. The grill wall should align with the -0.5 mark on the handle which should set the heat shield 9.25 in. from the left inside grill wall. See diagram below. The bottom of the heat shield has a V shape which is designed to split your rising heat left and right so ultimately you want this centered over the firebox. Positioning is crucial and can significantly influence internal temps and left to right hotspots.
VERY IMPORTANT: Install the grease try with the full circle cutout on the left, near the thermal sensor (hopper side) and the half-moon cutout on the right into the grease trough (chimney side). This ensures proper travel of grease into your grease trough. See diagram below.
For easy clean up, use our Drip EZ Grease Tray Liners or wrap the grease tray in tin foil. MAKE SURE not to cover up the circle on the left side near the thermal sensor.
ALWAYS close all lids and doors before starting the grill. This ensures proper airflow.

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 half inch adjustment can create a 50° difference. 9.25 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 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 blades do not spin, gently tap on the blades to release any debris. Replace if necessary
- 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.
Are you using a dark pellet, for example charcoal blend? If so, these pellets do not reflect light. You will need to disconnect the sensor when using these pellets.
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.
Simply press the red power button to switch it into fan mode.
NEVER just unplug the grill while it is on or in fan mode. Fan mode is very 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 has successfully powered down. You can leave the grill plugged in for quicker power up next time or unplug it if you prefer.

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.
Pellet bridging is the build up of pellets over the auger intake at the bottom of the hopper. This is a common symptom of loss of positive pressure.
Condensation can accumulate in the bottom of the hopper and in the auger tube causing pellets to stick together and build up. A few things to look out for:
- Make sure there is positive pressure by ensuring the hopper lid and pellet dump door are tightly closed.
- Make sure the type of pellets you’re using are not over 1 1/4 long. Longer pellets are prone to bridging.
- Pellets should have a shinny coating. If the shinny finish has worn down the pellets are deteriorating and will cause bridging.
Jammed Auger can be caused by a couple things:
Inorder to diagnose and resolve, first 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 firebox 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 firebox, 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 try and heat shield from the body of the grill. Remove all 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 properly.
There’s no need for concern if your fan is not blowing at a constant speed. The variable speed fan will run at various different RPM’s and pulsate in order to maintain the most stable and precise temperature. The fan should run continuously from cycle 2 on start-up until the grill completes the fan mode on power down.
To check if it’s running properly:
- Power down and unplug the grill once it has properly cooled down.
- 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 which is easily replaced.
- Check the wires leading to the combustion fan to make sure those connection are secure and undamaged.
Simply press the red power button to switch it into fan mode.
NEVER just unplug the grill while it is on or in fan mode. Fan mode is very 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 has successfully powered down. You can leave the grill plugged in for quicker power up next time or unplug it if you prefer.
