What should be the air flow temperature when conducting a PDI on RV furnaces?

When conducting a Pre-Delivery Inspection (PDI) on RV furnaces, the air flow temperature should be warmer than ambient temperature. This is important because the furnace is designed to produce heat, and during the inspection, it is essential to verify that the furnace is functioning correctly and effectively heating the air. A temperature warmer than the ambient level indicates that the furnace is working as intended and is capable of raising the air temperature to a comfortable level, which is crucial for the overall performance of the RV's heating system.

In many cases, a functioning furnace should produce air that is noticeably warmer, ensuring that it can adequately heat the living space when in use. If the temperature does not exceed the ambient temperature, it could suggest a potential issue with the furnace that needs to be addressed, such as improper combustion, airflow restrictions, or malfunctioning components.

By confirming that the air flow temperature is warmer than ambient during the PDI, you can ensure the reliability and efficiency of the furnace for the end user.
