Pellet cookers usually have an auger or another feed mechanism that pushes the pellets into a burn pot typically about the size of a beer can ripped in half. An igniter rod sits in the bottom of the pot and when you turn on the grill it glows like the element on an electric stove. As the pellets ignite, a fan blows to feed them oxygen, and the igniter shuts off. The Traeger L'il Tex, an inexpensive model, draws 300 watts an hour while the igniter rod is on in the first four minutes, then it drops down to 50 watts an hour for the duration of the cook session, less than a standard light bulb.

The Smart Smoke technology is one of the most convenient and easy to use features on the grill. It contains a dual LED temperature readout that keeps the heat at a constant temperature. This means you have more time for socializing and can sit back and relax. The temperature ranges from 160 to 500 degrees Fahrenheit. The grill uses a pellet feeder system that burns slowly to add intense flavor to your food. It also uses an electric auto-start ignition that requires the grill be plugged into a standard 120v outlet.

I watched the Traeger infomercial on T.V. Seemed easy enough. Ha! QVC ran a similar infomercial on their channel, seemed really easy. Ha! Like a fool and his money are soon departed, I jumped in and bought one. When it came in the mail, I started to assemble it. What a joke! No instructions came with it to tell me where the nuts and screws went. Called the manufacturer. The lady said they had many complaints with the QVC orders, she would email me a copy of the instructions. Well I finally put it together. Performed the (curing and start up method). Bought a nice pork shoulder and started grilling. It is interesting that both infomercials say set the temp and WALK AWAY!!! What a joke, I sat and watched the grill like a hawk for 3 hours, everything was good. I figured I would go eat lunch, ha! What a mistake. When I came back (20 min.) the grill had turned itself off and had an error on the screen.
The small burn pot is covered with a large deflector plate that absorbs the heat and spreads it out below the cooking surface making them essentially wood-fired convection ovens. Flare-ups are a thing of the past. You need to keep the plate clean because it is right below the food and if you leave sauce and grease on there, it can smolder and leave soot on your food. Carbon buildup will also diminish its heat transmission.
I have owned my YS640 for about 9 months now. Before I bought this I researched smokers/grills for about 2 years because I had very little experience with them & cooking in general. With the help of a few good websites I have produced some great food. There is a ton of room to cook on & the heat stays pretty much where you want it. Only a few issues I have had is that where the stack mounts to the side of the grill it drips. I did have a scratch on mine from the shipper & when I called about it I was sent a can of matching high temp paint very quickly. One thing that I like the most about this smoker is it is heavy. You can tell that this thing was built to last.
Joe Traeger first introduced the concept of Pellet Grill in 1980’s. Pellet grills are a rage amongst backyard grillers because they can grill, roast and smoke all in one. Since it uses indirect electric heat, there are no chances for it to burn into flames, unlike a gas grill. It is the perfect cooking appliance for a novice chef, looking to experiment with different dishes. Which is actually one of the primary reason for its unbelievable popularity.
So, when their patent expired in 2006, large companies capitalized on that one and Traeger began facing cut-throat competitions. Within two years, a few companies had already begun producing some of the best pellet grills with more advanced designs and features. By 2014, around 27 companies had already penetrated the market and newer brands were coming out almost every month. Now, with so many companies already in the market, some of them are creating strategic alliances with other brands producing different grilling equipment.

Pellet grills preheat quickly, so you can start cooking almost immediately, and the pellets are available in a number of woods, for different smoke flavors. The smoke has a subtle wood-fired flavor with less of the acrid flavor that comes from standard wood or charcoal. For the maximum smoke flavor, it’s best to cook at a temperature lower than 250 degrees, while higher temperatures cook faster with less smoke.
