How to Vent High Efficiency Furnace Outside
When wondering how to vent high efficiency furnace outside, it is critical to understand the importance of high-efficiency venting. A byproduct of burning natural gas is combustion gases. It is imperative to vent these dangerous combustion gases out of your home. A conventional gas furnace expels combustion gases through a vertical exhaust system attached to the furnace. Typically made of metal, the exhaust system removes the combustion gases. However, residual heat, mixed in with the combustion gases, is also lost through the ventilation. High-efficiency furnaces capture the residual heat lost through the venting process and extract the heat before venting a highly corrosive condensate made up of carbon dioxide and water. The corrosive condensate would ruin the venting equipment used in conventional gas furnace ventilation. Instead, high-efficiency furnaces use PVC pipes to remove the corrosive liquid.
Other Aspects Involved in the Venting ProcessYou now have a rough idea of how to vent high efficient furnace outside. However, there are other aspects you should consider in the venting process. Following, we discuss some of these aspects.
Electronic ignitionYour furnace should possess the electronic ignition mode. The electronically controlled ignition system uses a resistant heating element, similar to the bulb filament. In this paragraph, I will discuss a few reasons why a resistant heating element is beneficial:
- Its hot surface ensures the furnace burner ignites.
- It provides better safety options and better performance as opposed to the furnace’s pilot light.
- Because of its high operating efficiency, it gives the user energy-saving possibilities.
