Pellet stove pipe placement and sizing
Pellet stove installation tips for the pellet stove pipe classified as a environment friendly heater
The pellet stove pipe classified always as a very important part of the pellet stove installation. The pellet stove pipe harnesses the heat of the fire to create what's called a stack effect and as the warm air from the fire in the pellet stove rises, cooler house air rushes into the wood-burning appliance through a pellet stove vent, providing the oxygen the fire needs to burn. Starting a fire in pellet stoves with a good hot burn will encourage this healthy draft to flow.
Also, between the higher and lower pressure zones of the home lies a neutral pressure zone. The neutral pressure zone tends to move toward the largest air leak. When the top of the pellet stove pipe classified as the outlet is located above the home ceiling (as it should be), the pipe's neutral pressure zone is above the neutral pressure zone of the house. Such proper pellet stove pipe placement creates a gentle flow of air into the appliance and out the pipe even when no fire burns.
Pellet stove pipe classified for inside use?
If you are designing or building a new home, consider a pellet stove installation where the pellet stove pipe is placed inside your home. A more traditional pellet stove pipe classified for outside use, constructed along the outside of a home, will lose valuable heat to the cold, outside air. If the chimney air temperature falls below that of the inside air, the cold, smelly chimney air will be pulled into the house by the low pressure of the stack effect. In such a scenario, the house has become a better chimney than the pipe. So when a fire is lit, smoke fills the room.
Matching the size of the pellet stove pipe with your pellet stove during your pellet stove installation
You should have pellet stove pipes classified to match the size of the pellet stoves, meaning the flue size should match the stove outlet. If the pipe is bigger than the stove or fireplace outlet, exiting exhaust slows, increasing creosote buildup and decreasing efficiency.
High-performance chimneys are also insulated. Older masonry chimneys can be relined to safely and efficiently connect them to newer high-efficiency, wood-burning appliances.
Again, the pellet stove chimney liner should be continuous from the appliance outlet to the pipe top. It is not uncommon to pay as much for the pellet stove pipe as for your pellet stove.
Consider also in your pellet stove installation
Free-standing woodstoves exhaust into a connecting pipe, which then connects into the pellet stove chimney. If the connecting pipe is longer than 8 feet (as in a vaulted ceiling), you should consider investing in double-layer pipe with 1-inch airspace between pipe layers.
Efficient modern pellet stoves produce large amounts of heat. Much of this heat can radiate from a longer length of single-layer pipe, slowing down the draft, which can impact the overall efficiency of your wood-burning system.
A big thank you to the US Department of Energy for their help with the data for this pellet stove information.
