Cook With Confidence. Taste the Difference.

If you care enough about your outdoor cooking space to build a BBQ island or complete outdoor kitchen, then you care enough to appreciate the advantage of a Yoder Smokers YS640s.

Get more from the cooking you do every day—more options, more consistency, more genuine wood-fired flavor—by opting for an American-made Yoder Smokers.

Why Yoder Smokers? It’s the food.

Ask any Yoder Smokers YS640s owner what the best thing about their grill is, and they’ll tell you, it’s the food. There’s science behind why—why food cooked on Yoder Smokers pellet grills turns out more delicious, more often. And while you (probably) won’t be regaling your friends and family with stories about temperature stability and airflow next Fourth of July, those are some of our favorite stories, so here goes. A bit of the tech behind the unbeatable flavor:

• Temperature Stability - Industry-leading tech and construction prevent severe temperature fluctuations in the YS640s, providing a consistent cooking environment.
• Superior Airflow - The key to both a quality fire and evenly cooked food, the exceptional airflow from one end of the YS640s to the other infuses the food with rich flavor. 
• Precision Monitoring - Dual food probes deliver precise temperature readings to the grill’s display panel and your mobile device, so you know exactly when your food is done without needing to open the grill lid to check.

Seamless Outdoor Kitchen Integration

Developed for built-in applications, this kit is easy to place into (or on) an existing outdoor kitchen or island. Because it’s being placed directly into an existing kitchen structure, this model does not include a cart or stand. The bottom of the grill will simply seat into your non-combustible countertop material when installed correctly, creating a clean, intentional look. Your outdoor cooking space will look like it was designed for you specifically (because it was).

• Available with left-side or right-side hopper placement
• 10” recommended hopper-side clearance for serviceability
• 12” minimum cooking chamber clearance from combustible materials

Cook Any Style, Across the Temperature Spectrum (Smoke-Sear, 150º-600º F)

Truly a do-it-all grill, the YS640s excels at various cooking methods. It can smoke, sear, and roast from its standard setup, with oven-style baking possible when utilizing the included 2-piece second shelf. And with the quick and easy removal of a small access door, you can cook over direct flame at higher temps for a grilling experience that combines the convenience of gas grilling with the flavor-rich results of cooking over wood or charcoal. Additionally, some optional accessories allow you to expand your cooking even further:

• Yoder Smokers Wood-Fired Oven - An insert that rivals the best stand-alone wood-fired ovens on the market, the Yoder Smokers Wood-Fired Oven efficiently cooks everything from blistered, pillowy Neapolitan pizzas to crispy wings to roasted vegetables.
• GrillGrate Set for Yoder Smokers YS640s - Anodized aluminum GrillGrates, which quickly reach temperatures above 650º F, enhance your grill’s searing capabilities and reduce flare-ups almost completely, producing steakhouse-quality grill marks, textured crusts, and intense caramelization.
• Yoder Smokers Pellet Grill Rotisserie Kit - Chickens, turkeys, and prime ribs all develop a textured outside and tender inside with the self-basting magic of rotisserie cooking. Cook low and slow at 275–350°F, or move over direct fire for higher heat and more crust.

WiFi-Control from Anywhere

The Yoder Smokers YS640s features Yoder Smokers’ next-generation Adaptive Control System. It connects to both Bluetooth devices and your home Wi-Fi network via the FireBoard app on mobile devices. Once connected, you can remotely control your grill's temperature, monitor food with the two included temperature probes, change cooking programs to hold your grill at a set temperature once your food is done, and more—all from your phone.

• User-friendly mobile app is easy to set up and use
• Built-in temperature probes let you track food doneness and cook with confidence
• Monitor and adjust grill temperature on your mobile device

Ease of Use

While the YS640s is technologically advanced, it’s also incredibly easy to use. To start it, simply load the pellet hopper, power on the grill, fire it up with the simple push of a button, and set it to your desired cooking temperature. The grill will automatically run its ignition program and should reach the desired cooking temperature within 10-20 minutes.

We mean it when we say “hands-free” grilling with no babysitting involved. There’s no need to open the lid for temperature checks, which speeds up cooking and frees you up for other activities. You can trust that the YS640s is completing the task at hand, but for added peace of mind, simply check in via the Fireboard app to ensure your cook is proceeding as planned.

• Easy cleanup - simply brush the grates while they are still warm to remove grease and debris.
• Once the grill has cooled, dump any ash from the burn pot and wipe down the grill’s exterior. 
• When necessary, deep cleaning your Yoder Smokers Pellet Grill will keep it running and looking fantastic.

Fast Ignition, Efficient Burn, and Reliable Performance

Engineering details ensure you can trust the YS640s during long cooks and won’t have to constantly babysit your grill. Its high-capacity hopper holds a 20-pound bag of pellets and can run for approximately 10+ hours at 225°F. The high-airflow burn grate improves efficiency and prevents clogging by carrying ash away from the burn pot. The ceramic ignition system lasts five times longer than conventional contact igniters, heats up twice as fast, and generates 100% more heat using an induction lighting system that helps prevent failed ignitions.

• Built around a powerful microprocessor, the ACS board monitors multiple input variables to maintain precise, consistent grill temperatures. It intelligently responds to sudden temperature changes caused by opening the grill lid, adding cold meat, weather fluctuations, or shifts in pellet burn rates when changing pellet types mid-cook.
• Pellets last longer thanks to a more stable cooking environment inside the grill.

Temperature Control and Airflow that Make a Difference

Both the physical control panel and the mobile app allow you to adjust the temperature of the YS640s in 5°F increments. The controller is constantly monitoring the grill’s temperature and adjusts the pellet feed to maintain the target temperature with ±5 °F accuracy. And the grill’s consistent left-to-right airflow helps prevent temperature swings and soot buildup, improving performance and delivering delicious results.

• Ball-bearing fans enhance grill performance in cold weather. 
• An optional thermal jacket accessory helps retain heat and improve fuel efficiency in below-freezing temperatures.

1,070 Square Inches of True Cooking Freedom

With 1,070 square inches of total cooking space (640 square inches on the primary grate + 430 square inches on the upper shelf), the YS640s Built-In is the perfect size for large family meals or gatherings with numerous friends. The dual-level cooking area opens the door to multi-zone cooking, allowing you to sear meat over the firebox while baking a side dish on the modular 2-piece upper shelf. Offering flexibility to cook nearly anything an oven can handle — with added flavor — the YS640s can accommodate:

• 8-10 Racks of ribs at one time.
• 6-8 Pork shoulders at one time.
• 3-4 Packer briskets at one time.

Installation & Cut-Out Requirements for the YS640s Built-In

With three versatile installation options — surface mount, center mount, and notch mount — this kit is customizable to your space and style. The YS640s built-in model features a vented valance that fastens directly to the countertop, promoting airflow to dissipate heat and protect adjacent countertops from excess heat exposure.

Shipping and Assembly Instructions

Quick-Start Tips & Best Practices

The YS640s startup process is a breeze. Simply load up the pellet hopper, power up the grill, and hit the “START” button. The auger will immediately begin to move pellets into the burn pot. And finally, the ceramic igniter will power on to initiate the induction heat combustion process.

Visible flames will appear within four minutes, while the fans and auger work together to fuel the fire and help bring the grill up to its target temperature. For best results:

• Clean the burn pot of any ash or debris after each use so that it is ready for the next cook.
• Allow the grill to reach the desired temperature before putting food on to cook. 
• Take weather conditions into consideration, as the heat-up process will take longer when temperatures are low.
