The Reznor 270613 Combustion Air Inlet-Adapter designed to provide fresh air from the outside into the combustion chamber of the HVAC system. It also eliminates the use of indoor air by the heater and avoids the formation of negative pressure and back-drafting. This better combustion increases fuel conversion and decreases gas emissions. The adapter used to prevent the accumulation of dust, debris, and other materials that compromise the efficiency. It is useful in sealed combustion applications that protect the burner from indoor air and, therefore, increase the safety of the system.
