This standard applies to newly produced automatic burner ignition systems and system components constructed entirely of new, unused parts and materials for the automatic control of burners for one or more of the following fuels:

Oil; Natural gas; Manufactured gas; Mixed gas; Liquefied petroleum gas; or LP gas-air mixtures.

This standard is applicable to a complete burner ignition system, a separate programming unit, an oxygen depletion safety shutoff system and components that perform one or more of the following functions: a. Ignite the fuel at the main burner(s), or at the pilot burner(s) so it can ignite the main burner(s); b. Prove the presence of either the ignition source, the main burner flame, or both; c. Automatically act to shut off the fuel supply to the main burner(s), or to the pilot and main burner(s), when the supervised flame or ignition source is not proved; and d. Automatically act to shut off the gas supply to the pilot and main burner(s), when the oxygen content of the room in which the equipment is installed is reduced below a predetermined level.
