[header] How to start a pellet stove [title] Read the instruction manual first. [step] An automatic start pellet stove doesn't require an igniter, like a lighter or match, in order to get started. Read the instruction manual so you know where to pour the pellets and any other details or warnings you need to know. <sep> (A) [substeps] The instruction manual will tell if you have an automatic or manual start pellet stove. Automatic pellet stoves will have a control panel with an on/off button or switch. (B) [substeps] If you are trying to start a pellet stove from scratch, always refer to the instruction manual to help you develop an optimal fuel start. [title] Fill the ring at the bottom of the opening to prevent your stove from falling off. (C) [substeps] To begin working inside the stove, retrieve an empty can about 2 inches (5.1 cm) in diameter. At this length, you will pour the pellets into the hopper, or bucket inside the hopper. (D) You also may want to refer to the stove's instruction manual to find out exactly how much of each pellet you'll need. You may want to write down the instructions inside the manual so you can refer to them throughout the cooking process.
