  2. If you would the pellet pipe inside your home to be black, consider painting it with high temperature paint.
  3. Some pellet experts mention that when a pellet vent pipe increases from 3″ to 4″ and / or has a vertical rise (including past the roof) – a pellet stove operates cleaner and more efficiently.
  4. Because the exhaust of a pellet stove is often off-center, some customers will angle the first part (45 degree and / or Tee) so that the vertical rise appears in the middle of the pellet stove instead of off to one side for cosmetic reasons.
