Do I have to vent my pellet stove insert? Do I have to vent my pellet stove insert?
Yes, a pellet stove insert has to be vented because, while they do not create a visible smoke like traditional wood burning fires, they do create waste substances. These waste substances are include water vapors, exhaust gas and fine ash. The correct vent to use for a pellet stove insert is a PL Vent Pipe. These are tightly joined so that the exhaust gas cannot leak out. Alternatively, if you have a working chimney, this can be used as a vent, depending on its condition. A poorly conditioned chimney will need to be lined with a metal liner. However, you must stay clear of using PVC or plastic piping, as these materials will melt when exposed to the heat.
