Exemption for Propane-Converted Gas Appliances from Nitrogen Oxide Rules

This law states that rules limiting the sale or use of gas furnaces and water heaters based on nitrogen oxide emissions do not apply if the appliance is installed with a kit to run only on propane.

What This Bill Does

  • Creates an exception for regulations prohibiting or restricting the sale or use of gas-fired appliances based on oxides of nitrogen limits.
  • Applies this exemption only when the appliance is installed with a conversion kit specifically for propane firing.

Who It Names or Affects

  • Air pollution control districts
  • Air quality management districts
  • The State Air Resources Board

Terms To Know

Limits and Unknowns
