What You Need to Do to Start Your Green Mountain Grill
How to start a Green Mountain Grill the right way is key to getting steady heat, clean ignition, and great flavor from every cook. Following the correct startup sequence protects your grill, improves efficiency, and prevents temperature issues over time.
Placing the grill in a safe location, powering it up correctly, allowing it to preheat fully, and shutting it down properly all play a major role in performance and longevity. Even small mistakes—like skipping the initial burn or interrupting Fan Mode—can lead to long-term maintenance problems.
From our hands-on experience with every GMG model, following the proper steps gives you predictable temperatures, better pellet usage, and smoother day-to-day operation. This improved guide walks you through the entire startup process so your grill runs exactly the way it should from the very first cook.

How to Start a Green Mountain Grill (Step-by-Step)
Below is the full process for both the initial startup and the standard daily startup sequence. These steps apply to all current GMG models and help prevent ignition problems and performance issues.
Step 1: Prepare Your Grill
Before powering on your Green Mountain Grill, place it in a safe, level, well-ventilated outdoor area at least 48 inches away from walls, structures, or overhangs to ensure proper airflow and reduce fire risk.
Next, ensure the hopper lid, grease tray, ash cleanout, and rear vents are in their proper positions. Proper setup prevents airflow issues and helps the ignition cycle run smoothly.
Taking a minute to prep the grill helps ensure reliable ignition and smooth airflow throughout the cook.
Step 2: Power It On
Plug in the grill and verify that the display reads “OFF.” If the display is blank, press and hold the red power button for 7 seconds until “OFF” appears.
This confirms the controller is active and ready for startup. Always use a dry and stable power source to avoid electrical problems outdoors.
Step 3: First Startup
If this is your first time using the grill, you must prime the auger before switching to standard operation. Press the red power button once—“0” will appear, then progress to “1.” When it does, unplug and replug the grill.
The display should return to “OFF,” confirming the auger is primed and ready for normal use. After this, you can use the standard startup method for all future cooks.
Step 4: Standard Startup
With the grill plugged in and the display showing “OFF,” press the red power button to start the unit. The grill will automatically run through the 0–1–2–3 startup cycle before heating to 150°F.
If the display is blank when plugged in, hold the red power button for 7 seconds until “OFF” appears, then press it again to begin the startup cycle.
Step 5: Initial Burn
Before your first cook, set the temperature to 350°F and let the grill run for 30 minutes with the lid closed. This burns off manufacturing oils and protective coatings.
A light odor or smoke during this cycle is normal. Once complete, allow the grill to cool before your first real cook.
Step 6: Adjusting Temperature & Cooking
Once the grill reaches 150°F, you can adjust the temperature using the control panel or the GMG app. Higher-quality pellets deliver more consistent performance and steadier heat.
Let the grill stabilize at the selected temperature before adding food. Once preheated, load your meats, vegetables, or pizzas and let the GMG handle the rest.
Step 7: Proper Shutdown
When the cook is finished, press the red power button once to enter Fan Mode. This clears ash from the firebox and cools the grill safely.
Never unplug the grill or interrupt Fan Mode. When the display reads “OFF,” hold the red power button for 7 seconds until the screen goes blank. The grill is now fully powered down.
Conclusion
Learning how to start a Green Mountain Grill correctly ensures stable temperatures, clean ignition, and longer grill life. Preparing the grill, completing the full startup sequence, preheating to 150°F, and using proper shutdown procedures all contribute to smoother cooks and better results.
By following these steps, you avoid common issues and set yourself up for consistent, enjoyable grilling every time. For pellets, accessories, or help choosing the right GMG model, visit DDR BBQ Supply.
How to Start a Green Mountain Grill (FAQs)
How long does a Green Mountain Grill take to heat up?
Most GMG units reach cooking temperatures (225°F–350°F) in 15–20 minutes. Cold weather can extend this slightly. Always let the grill reach 150°F before setting your target temperature.
Why is my Green Mountain Grill making a huffing or whirring noise?
The combustion fan cycles on and off to adjust airflow and maintain temperature. A light “huffing” or “whirring” sound is completely normal and indicates the grill is regulating oxygen levels properly.
How often should I clean the ash from my grill?
Clean the ash every two to three bags of pellets (80–100 lbs). Removing excess ash improves airflow, ignition reliability, and temperature stability.
