scope:

This clause of part 1 is applicable except as follows:

Replacement:

This standard modifies or amends the requirements of the Part 1 standard. In Canada the Part 1 standard applicable is CAN/CSA E60730-1, Automatic electrical controls for household and similar use - Part 1: General Requirements, and in the U.S. the Part 1 standard applicable is UL 60730-1A , Automatic electrical controls for household and similar use - Part 1: General Requirements, 3rd Edition.

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.

Components can be, but are not limited to: automatic controls; pilot burners, thermoelectric devices, electrodes, ignition devices, ignition sources and flame detectors.

Throughout this standard the following terms shall be abbreviated as shown below:

1. "system" means "burner ignition system."

2. "component" means " burner ignition system component."

3. "control" means "system" or "component."

Requirements for separate ignition transformers are covered in Standard for Specialty Transformers, UL 506, and CSA C22.2 No. 13, the Standard for Luminous Tube Signs, Oil and Gas Burner Ignition Equipment, Cold-Cathode Interior Lighting.
