Abstract
A method of operating a HVAC system is provided. The method includes transferring heat between airflow and a heating element in the duct system. The heating element is configured to receive a fuel and ignite the fuel to heat the heating element. The method includes measuring a change in at least one gas property value of the airflow in the duct system using a leak detection sensor, where the change in the at least one gas property value is indicative of a gas leaked into the duct system. The method includes determining a concentration of the leaked gas based at least in part upon the change in the at least one gas property value and determining that the concentration as measured by the leak detection sensor has a negative value, where the negative value is indicative of the leaked gas comprising fuel.
