Dos and Don'ts of Pellet Venting


  • Do ensure proper clearance from combustibles as specified by the manufacturer to avoid fire hazards.
  • Do have your venting system professionally installed to ensure it complies with local building codes and manufacturer's guidelines.
  • Do conduct regular inspections and maintenance to ensure your venting system remains in good working condition, especially before the start of the heating season.
  • Do follow the manufacturer’s guidelines for your specific stove model and venting system to maximize efficiency and safety.
  • Do ensure there is adequate air supply for the stove to operate effectively, as insufficient air can cause poor combustion and increased emissions.


  • Don't modify or alter the venting system without consulting a professional. Unauthorized modifications can void warranties and may create safety risks.
  • Don't ignore signs of wear or damage. Regular checks can help identify issues early, preventing potential failures or hazards.
  • Don't use unauthorized fuels in your stove, as they may not be compatible with your specific venting setup and could pose safety risks or reduce system efficiency.
  • Don't obstruct the venting system’s outlets or inlets, as this can lead to dangerous accumulations of gases or hinder the performance of your stove.
  • Don't skip on using the correct type of vent pipe specified for your heating appliance, as using the wrong type can lead to inefficiencies and safety issues.

These guidelines will help ensure that your PelletVent system operates safely and efficiently, providing reliable service while minimizing the risk of fire and other hazards.
