The Combustion Engine is a wireless, rechargeable fan that controls the temperature of your charcoal grill or smoker for you. It mounts to your grill&apos;s air intake and adjusts airflow automatically (more air means a hotter fire, less air means a cooler one) so your grill holds the temperature you set. This guide gets you from the box to your first cook.<hr><h2 dir="ltr" id="isPasted">What&apos;s in the box</h2><ul><li dir="ltr" style="font-size: 14px;">Combustion Engine blower unit (the fan)</li><li dir="ltr" style="font-size: 14px;">The Standard Mount</li></ul>(If your grill needs a grill-specific adapter, that&apos;s ordered separately.

To get accurate, automatic temperature control, pair the Engine with a Giant Grill Gauge or a Predictive Thermometer so it can read your grill temperature and adjust airflow to match your target.<ul style="font-size: initial;"><li dir="ltr" style="font-size: 14px;">A Giant Grill Gauge is ideal.&#xA0;It measures the temperature inside your grill most accurately, exactly the reading the Engine needs to hold a steady temp.</li></ul></li><li style="font-size: 14px;">The Combustion app (needed to set up). You&apos;ll use the app once to set the Engine up and choose which device it controls (your Giant Grill Gauge or Predictive Thermometer). After setup, the dial&apos;s manual fan mode runs on its own. But the app is what coordinates the Engine with your gauge or probe, so keep it connected for automatic temperature control, monitoring, graphing, and alerts.</li></ul><hr><h2 dir="ltr" id="isPasted">Setting up your first cook</h2><ol><li dir="ltr" style="font-size: 14px;">Charge the Engine fully before your first cook. (Approx 70-90 min via USB-C PD, 4.5 h via standard 5V USB-C. )</li><li dir="ltr" style="font-size: 14px;">Set up the Engine&#xA0;in the Combustion app and select your control device, either a&#xA0;Giant Grill Gauge&#xA0;or a&#xA0;Predictive Thermometer.</li><li dir="ltr" style="font-size: 14px;">Install the Engine on your grill&apos;s lower air intake using the correct mount or adapter. On Big Green Egg and most kamado grills, the mount uses the existing vent openings and snaps into place with a clip. If you&apos;re using the universal bracket, tighten it only finger-tight with a slight additional turn. Overtightening can deform the bracket and reduce airflow.</li><li dir="ltr" style="font-size: 14px;">Position your Giant Grill Gauge or Predictive Thermometer&#xA0;away from the incoming air from the Engine. Avoid placing it directly in front of the air inlet, as this can cause unnecessary temperature swings and reduce control accuracy.</li><li dir="ltr" style="font-size: 14px;">Close all other bottom air vents.&#xA0;The Engine should be the only source of incoming air. Make sure the ash drawer and any additional lower vents are fully closed.</li><li dir="ltr" style="font-size: 14px;">Adjust the top vent. On a kamado, leave it only slightly open. On a kettle grill, open it a bit more. The grill still needs an exhaust path, but not a fully open chimney.</li><li dir="ltr" style="font-size: 14px;">Light the charcoal and allow the fire to become established. For faster startup, use the Engine&apos;s manual fan mode to build the fire, then switch to automatic temperature control once the coals are burning well.</li><li dir="ltr" style="font-size: 14px;">Set your target temperature using either the control dial or the Combustion app.</li><li dir="ltr" style="font-size: 14px;">Let the Engine take over. It automatically adjusts airflow to bring your grill to the target temperature and keep it there. As the cook progresses, the Engine learns how your grill behaves and fine-tunes its control for even more stable temperatures.</li></ol>Big Green Egg tip:&#xA0;For the best airflow, run the Engine with the Egg&apos;s vent screen removed.<hr><h2 dir="ltr" id="isPasted">Using the dial</h2>The dial is your main control during a cook, and you turn it to Off when you&apos;re done. There are three ways to run the Engine:<ul><li dir="ltr" style="font-size: 14px;">Manual fan mode: you set the fan speed by hand. Great for getting the fire going before you switch to a temperature. This mode runs from the dial on its own.</li><li dir="ltr" style="font-size: 14px;">Temperature presets: pick a numbered target on the dial and the Engine holds it (with a Giant Grill Gauge or Predictive Thermometer connected).</li><li dir="ltr" style="font-size: 14px;">App mode: set a precise target and monitor from your phone.</li></ul>The temperature-holding modes rely on your Giant Grill Gauge or Predictive Thermometer, coordinated through the Combustion app.<hr><h2 dir="ltr" id="isPasted">How the Engine holds your temperature</h2>In automatic mode, the Engine reads your grill temperature from your Giant Grill Gauge (recommended) or Predictive Thermometer and pulses air into the fire to match your target. It learns your grill by running short test cycles: it blows a bit of air, measures how your grill&apos;s temperature responds, then fine-tunes its air pulses to hold your target. So control tightens as the cook goes on, and you don&apos;t have to tell it what kind of grill you have.One thing worth knowing: the Engine adds air to raise the temperature, but it can&apos;t actively cool your grill down. If you overshoot your target, it eases off the air and lets the fire settle rather than forcing the temperature down. Setting your top vent correctly helps it hold a tight temperature.<hr><h2 dir="ltr" id="isPasted">Turning the Engine off</h2>Turn the dial to Off. The fan stops, and an internal door closes to limit air draw through the unit. When you&apos;re done cooking, you can remove the blower from the mount for charging and storage.<hr><h2 dir="ltr" id="isPasted">Cooking at high heat (protect your adapter)</h2>The Engine can be set up to 575&#xB0;F, but for high-temperature cooks it&apos;s important to keep the mount away from direct contact with the coals. The adapter is made from high-temperature plastic that begins to soften around 450&#xB0;F and can melt if a hot coal lands on it.<ul><li dir="ltr" style="font-size: 14px;">At 500&#xB0;F and above, keep the mount or bracket&#xA0;3 to 4 inches away from the hot coals. On a Weber Kettle, place the coals on the opposite side of the grill from the mount.</li><li dir="ltr" style="font-size: 14px;">Do not attach the Engine while adding lit coals. A falling coal can melt the adapter almost instantly. Install the mount first, then add the coals.</li></ul>If the adapter becomes scorched, it&apos;s usually only cosmetic and won&apos;t affect the Engine itself. However, if the adapter melts significantly, it will need to be replaced, so a little care during setup goes a long way.<hr><h2 dir="ltr" id="isPasted">Cleaning, storage &amp; travel</h2><ul><li dir="ltr" style="font-size: 14px;">Cleaning:&#xA0;The Engine is weather-resistant, with built-in drain holes, but it is&#xA0;not fully waterproof. Wipe it clean with a damp cloth or a sponge and a little dish soap. Do not hose it down or submerge it in water.</li><li dir="ltr" style="font-size: 14px;">Storage:&#xA0;After each cook, remove the blower unit from the mount and recharge it so it&apos;s ready for your next use.</li><li dir="ltr" style="font-size: 14px;">Travel: Before packing the Engine, place a piece of tape over the control dial to prevent it from turning on accidentally. The battery has passed UN38.3 transportation testing, so it is safe to bring on commercial flights.</li></ul><hr><h2 dir="ltr" id="isPasted">If the Engine can&apos;t reach your target temperature</h2><ul><li dir="ltr" style="font-size: 14px;">Check that every other vent is sealed.&#xA0;If air is leaking in elsewhere, the Engine can&apos;t control the fire.</li><li dir="ltr" style="font-size: 14px;">Make sure your top vent is open a little but not wide open.</li><li dir="ltr" style="font-size: 14px;">Add charcoal if your fire is dying. A fading fire is the most common reason the Engine can&apos;t reach a higher target.</li></ul><hr><h2 dir="ltr" id="isPasted">FAQ</h2>Can I use the Engine without the app?You&apos;ll need the Combustion app for the initial setup and to choose which device controls the Engine. After that, you can use the dial&apos;s&#xA0;manual fan mode&#xA0;without the app. However,&#xA0;automatic temperature control, monitoring, and remote access&#xA0;require the app because it coordinates communication between the Engine and your Giant Grill Gauge or Predictive Thermometer.Does the Engine send my grill temperature to the app?Yes. When paired with a Giant Grill Gauge or Predictive Thermometer, the Engine works with the Combustion app to display both your&#xA0;grill temperature&#xA0;and&#xA0;food temperature&#xA0;in one place, making it easy to monitor your cook.Do I need a separate thermometer to use the Engine?Not if you&apos;re using&#xA0;manual mode. In manual mode, the Engine functions as a variable-speed fan that you control with the dial. For&#xA0;automatic temperature control, however, you&apos;ll need either a&#xA0;Giant Grill Gauge&#xA0;or a&#xA0;Predictive Thermometer&#xA0;so the Engine has a grill temperature to regulate. The Giant Grill Gauge is the recommended option because it provides the most accurate measurement of your grill&apos;s internal temperature.What happens if the Engine loses its connection during a cook?If the connection is lost, place the Engine and its paired Giant Grill Gauge or Predictive Thermometer next to each other for about&#xA0;30 seconds, then power the Engine off and back on. This will usually re-establish the connection. We&apos;re aware that occasional signal drops can happen in some setups, and we&apos;re continuing to improve connection reliability through firmware updates.<hr> <h2 id="isPasted">Still stuck?</h2>If your Engine will not hold a temperature, will not connect, or is behaving in a way this guide does not cover, email support@combustion.inc&#xA0;and include:<ul><li style="font-size: 14px;">Which grill or smoker you have, and which mount or adapter you are using</li><li style="font-size: 14px;">Whether you are controlling it with a Giant Grill Gauge or a Predictive Thermometer</li><li style="font-size: 14px;">Where the dial is set, and what the Combustion app is showing</li><li style="font-size: 14px;">The firmware version on your Engine</li><li style="font-size: 14px;">A photo of the Engine mounted on your grill, with the vents visible if you can</li></ul>The Engine is our newest product, and that level of detail genuinely helps.

It uses a&#xA0;variable-speed fan that delivers up to&#xA0;15 CFM of airflow, pulsing air into the fire based on live temperature feedback instead of running continuously. When you need maximum heat,&#xA0;Max Sear mode runs the fan at full power to bring the grill up to temperature as quickly as possible.For&#xA0;automatic temperature control, the Engine must be paired with either a&#xA0;Giant Grill Gauge or a&#xA0;Predictive Thermometer&#xA0;to provide the grill temperature. The Giant Grill Gauge offers the most accurate measurement of the grill&apos;s internal temperature, making it the preferred control device. Without one of these devices, the Engine operates only in&#xA0;manual mode as a variable-speed fan and cannot maintain a target temperature.Because the Engine regulates temperature by controlling airflow to the fire, it can&#xA0;raise and maintain your target temperature but cannot actively cool the grill. If the grill gets too hot, the Engine simply reduces or stops airflow and allows the fire to settle naturally.<hr><h2 dir="ltr" id="isPasted">Battery &amp; charging</h2>The Combustion Engine is powered by a built-in&#xA0;1,500 mAh, 3-cell rechargeable lithium-ion battery. Because the fan pulses air only when needed instead of running continuously, a full charge typically provides&#xA0;about 24 hours of normal cooking. If the fan runs at full speed continuously, battery life is approximately&#xA0;2.5 hours. Actual runtime depends on cooking conditions, with colder weather or a struggling fire requiring the fan to work harder.The Engine charges via&#xA0;USB-C and is compatible with any standard USB-C charger, including&#xA0;5V chargers and&#xA0;USB Power Delivery up to 15V.<hr><h2 dir="ltr" id="isPasted">Connectivity</h2>The Combustion Engine communicates over&#xA0;Bluetooth. During setup, you&apos;ll use the Combustion app to pair the Engine and choose which device will control it, either a&#xA0;Giant Grill Gauge or a&#xA0;Predictive Thermometer.For automatic temperature control, the&#xA0;Combustion app acts as the coordinator, relaying temperature data from your Giant Grill Gauge or Predictive Thermometer to the Engine. Because of this, the app needs to remain connected while the Engine is operating in automatic mode.If you&apos;re using the Engine in&#xA0;manual fan mode, the control dial works independently and does not require the app after the initial setup.<hr><h2 dir="ltr" id="isPasted">Durability</h2>The Combustion Engine is&#xA0;weather-resistant, with built-in drain holes, but it is&#xA0;not fully waterproof. If it gets caught in an unexpected rain shower during a long cook, it should continue operating normally. However, do not hose it down or submerge it in water.To clean the Engine, simply wipe it with a damp cloth or use a sponge with a small amount of dish soap. After each cook, remove the blower unit from the mount and store it in a dry place until your next use.<hr><h2 dir="ltr" id="isPasted">Temperature unit options</h2>The Engine comes in a Fahrenheit version and a Celsius version, priced identically. Pick whichever matches how you cook.<hr><h2 dir="ltr" id="isPasted">FAQ</h2>How long does the battery last? The Engine typically runs for&#xA0;about 24 hours on a full charge during normal cooking because the fan only runs when needed. If the fan operates continuously at full speed, battery life is approximately&#xA0;2.5 hours. Runtime will be shorter in cold weather or when the fire requires more airflow to maintain temperature.Can I use it while it&apos;s charging? Yes. The Engine can operate while connected to a&#xA0;USB-C charger, making it ideal for especially long cooks.How powerful is the fan? The Engine&apos;s variable-speed fan delivers up to&#xA0;15 CFM&#xA0;of airflow. It also includes a&#xA0;Max Sear mode that runs the fan at full power for rapid heat-up. During normal cooking, the fan pulses at lower speeds as needed to maintain your target temperature.Is it waterproof? No. The Engine is&#xA0;water-resistant, with built-in drain holes, but it is&#xA0;not fully waterproof. It can handle an unexpected rain shower during a cook, but it should not be hosed down or submerged in water. Clean it with a damp cloth or a sponge and mild dish soap.Can I travel or fly with it? Yes. The Engine&apos;s battery has passed UN38.3 transportation testing, making it safe for air travel. Before packing it, place a piece of tape over the control dial to prevent it from turning on accidentally during transport.<hr> <h2 id="isPasted">Still have a question?</h2>If there is a specification here you need and cannot find, email support@combustion.inc and ask.

<h2 dir="ltr" id="isPasted">Which mount do I need for my Combustion Engine?</h2>The Combustion Engine mounts on your grill&apos;s lower air intake vent, which is where it controls your fire by pushing air in. Finding your fit is a two-step process:<ol><li dir="ltr" style="font-size: 14px;">See if one of our existing mounts fits.&#xA0;Print our life-size Mount Fitment Guide and hold your grill&apos;s intake opening against the shapes.</li><li dir="ltr" style="font-size: 14px;">If none fit, measure your opening. Use our Mounting Plate Fitment Guide and send us the numbers, and we&apos;ll match a stocked plate or help make a custom one.</li></ol>Every Combustion Engine order also includes a Standard Mount, which fits many common grills.<hr><h2 dir="ltr" id="isPasted">Start with the included Standard Mount</h2>Every Combustion Engine comes with a Standard Mount, a plastic duct with a compressible silicone gasket and a metal mounting bracket. It fits most grills with an adjustable bottom-vent opening, as long as the opening is at least 0.75 inches. That covers a lot of common grills, including the Weber Smokey Mountain,&#xA0;PK Grills, and similar grills with an open bottom vent. (Weber Kettles usually need a small drilled hole. See Step 3.)Fitting the mount: don&apos;t over-tighten it; finger-tight plus a slight turn is enough. Over-tightening can deform the bracket and restrict airflow. The silicone gasket leaves a small gap that closes as you tighten; a little air leakage is fine, and you can fill any larger gaps with foil or high-temp flue tape.<hr><h2 dir="ltr" id="isPasted">Add a grill-specific adapter if you have a Kamado</h2>If you have a ceramic kamado, you&apos;ll want one of the optional mounting adapters (sold separately).

Older kettles&#xA0;with a rotating vent door often already have holes you can use; newer kettles have a bowl-shaped bottom that needs a custom-drilled hole. Once the hole is made, close the ash-catcher vent and seal any other openings so all the air comes through the Engine. High-temp flue/chimney tape works well for a non-permanent seal.When cooking hot, keep the coals on the opposite side of the kettle from the mount so they don&apos;t sit against the adapter.(This is the one grill where you may need to modify your equipment. If you&apos;d rather not drill, reach out, and we&apos;ll help you weigh your options.)<hr><h2 dir="ltr" id="isPasted">&quot;My grill isn&apos;t listed. Will the Engine work?&quot;</h2>Very possibly!

Send us your grill&apos;s make/model and a photo of the intake, and we&apos;ll point you to the right one.<hr><h2 dir="ltr" id="isPasted">FAQ</h2>Does the included Standard Mount fit my grill?If your grill has an adjustable bottom-vent opening of at least 0.75 inches (like a Weber Smokey Mountain or PK Grill), yes. Weber Kettles usually need a small drilled hole first (see Step 3). Ceramic kamados and Big Green Eggs use a grill-specific adapter instead (see the table above).How do I know which adapter to pick?Match your grill in the adapter table, or print the life-size Mount Fitment Guide at 100% and hold your intake against the shapes. Still unsure? Measure your opening with the Mounting Plate Fitment Guide and send us the numbers.My grill isn&apos;t a Weber or a Big Green Egg. Can I still use the Engine?Very likely. Check the adapter table and life-size guide first; if nothing fits, measure your opening and we&apos;ll match a stocked plate or make a custom one.Do I have to drill or modify my grill?Most kamados and adjustable-vent grills work as-is. Weber Kettles are the exception: they usually need a ~3/4&quot; hole drilled in the bottom grate (older models with a rotating vent door may already have usable holes). For unusual grills, we&apos;ll sort out a plate rather than have you modify the grill.<hr> <h2 id="isPasted">Still not sure?</h2>If you have worked through the fitment guides above and still cannot tell which mount you need, send your grill&apos;s make and model plus a photo of the intake area to support@combustion.inc, and we will tell you which one to order.
