About venting your stove

A properly designed and installed ventilation system for a pellet, or wood stove will meet three basic criteria.

Firstly, the waste gas from the combustion of fuel will not accumulate inside your home. Second, the installation of the ventilation system will not damage the structural integrity of the home. Finally, the oxygen consumed for the ventilation process must be able to be restored.
                                                                                                                                  An effective ventilation system for a pellet stove will safeguard the structure it is installed in from overheating the surrounding fixtures, such as frames and walls. High heat over a prolonged amount of time can cause surrounding materials to dry out, which lowers the combustion threshold, which will, in turn cause burning, even if direct flame is not applied.  

A trained installer is aware of the “combustion clearance” for different types of ventilation. Careful installation will ensure that your pellet stove operates in a safe and effective manner. By reducing the temperature of the waste gases, and by careful design, utilizing intervening air pockets.
                                                                                                                       Condensation of water vapor can cause damage to the stove, the vents, furnishings, and the building itself if not properly vented. If flue gasses cool too much before being vented, condensation may occur, causing damage to the system.
                                                                                                                                 The most crucial piece of the ventilation puzzle involves providing an adequate oxygen supply for the home’s inhabitants. Combustion of any material consumes and transforms oxygen. An adequate oxygen supply is also essential for complete and efficient combustion of fuel sources. Factors to be taken into account when installing a new pellet stove include the size of the space to be heated, as well as the natural ventilation properties of the house, or the lack thereof.

It is important to be aware of the fact that there are a number of situations that can cause negative pressure inside a home, such as other vented appliances, like clothes dryers, hot water tanks, and bathroom exhaust fans.
