To start using the grill, pour wood pellets into a hopper (pellets are usually are made from compressed sawdust). Press the start button to ignite the pellets, which are fed into the fire box with an auger, where a controlled number of pellets are lit and burned (depending on the temperature setting selected). The auger adjusts the number of pellets entering the fire box to maintain the desired temperature.
Purchased my grill last fall at Costco, overall it works OK, some meats like Lamb Chops are just delicious. However, customer service seems to be deteriorating as the company is having success. My kids recently purchased me an add on to my Pro 34, a cold smoker. Traeger sells this but does not support it. The installation instructions are incomplete, I was sent parts that do not go with the unit, then customer service couldn't figure it out, this went on for weeks. After getting it installed, I asked for some instructions or recipes on how to use it, there are none. The old cover does not fit now, and Traeger does not sell one to go with a unit with a cold smoker, or plan on doing so. After a web search, I found one at Charbroil that kinda fits. Also, I just saw the same model at Orchard Supply, it now comes with more shelves and upgrades which I now have to buy as extras.
***Update: 11/2014: It's been a year now and I still adore this little grill. I've got a kamado and 3 different kettles and this is by far the most convenient and easy to use. The smoke rings this guy puts on a brisket are amazing and the flavor is the perfect balance of wood flavor without overpowering the meat. I've researched about 15 different pellet grills and I still can't find a better value than what this grill offers
I was so excited to get this grill for the weekend. It was easy to assemble and get going. It has a great place for me to keep my bbq tools and a front rack to set stuff down so I am able to easily put things on and off the grill. We made steak and lobster tails and they could not have turned out better and it came with a cookbook to know exactly how to do it!
Although these are marketed as grills, they do much more, including baking or roasting. Because they heat by convection, you might not get the grill marks that a gas or charcoal grill will give you, but you also won’t have the flame-up problems. While many pellet grills offer high cooking temperatures, the maximum depends on ambient temperature and wind. Many users wrap their grills in special insulating covers to help maintain heat, reduce fuel use, and reach the higher temperatures they desire.
