In NFPA 54, what are thermostats designed to do?

Thermostats are specifically designed to control the temperature settings of appliances, particularly those that use gas for heating. In the context of NFPA 54, which deals with the National Fuel Gas Code, thermostats play a crucial role in ensuring that appliances operate within safe and efficient temperature ranges.

By regulating the temperature, thermostats help maintain comfort levels in residential and commercial spaces while also preventing overheating, which could pose safety hazards. Moreover, proper temperature control contributes to operational efficiency, helping to ensure that appliances burn fuel correctly and minimize unnecessary fuel consumption.

While other devices may address air quality, fuel efficiency, or humidity levels, the direct function of a thermostat is to manage and maintain temperature settings, making it a vital component in the safe and effective use of gas appliances.
