Most businesses that install a waste oil furnace are looking to save money on heating bills. While you might want to focus on the energy saving and eco-friendly benefits of switching to waste oil heating, you should make sure safety is a top priority when you’re ready to install your waste oil furnace’s chimney components.

Our Clean Energy Heating Systems Owner’s Manual provides valuable safety information and tips about installing chimney components. This handy reference guide includes specific instructions and requirements for optimal safety and performance of your waste oil furnace.

When you’re ready to install your Clean Energy furnace’s chimney components, be sure to heed these requirements and safety precautions:

  • Use double wall “Class A” insulated stack when making a penetration through the roof or side wall of your building to avoid creating a fire hazard.
  • Install proper flashing around the exterior penetration of the stack to make a watertight seal.
  • Use only a “Class A” non-restrictive stack cap.
  • The CE-140, CE-180, and CE-250 furnace models require 6” I.D. stack components.
  • The CE-330 and CE-440 furnace models require  8” I.D. stack components.
  • Make sure you have a vertical chimney of at least 10 feet.
  • Keep horizontal runs short and slope horizontal sections at no less than 1/4” per foot.
  • Keep the stack installation simple. If you have multiple turns and horizontal runs, you will reduce the natural draft of the furnace. This could damage critical burner components.
  • Install a barometric damper to monitor draft.
  • Do you have an exhaust fan in your building? If so, make sure adequate make-up air is available. Otherwise, it will create a vacuum in your building and cause a back draft at the furnace, which will damage critical burner components.

By installing and maintaining your waste oil furnace and chimney components properly, you will help maximize its performance and ensure that it gives you the biggest return on your investment.
