Automatic Electrical Controls for Household and Similar Use – Part 2: Particular Requirements for Burner Ignition Systems and Components
UL 372
1 Scope and normative references
This clause of part 1 is applicable except as follows:
1.1 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.
1.1.1 Replacement:
This standard applies to inherent safety; to the manufacturer’s declared operating values, operating times and operating sequences where such are associated with burner safety and to the testing of systems and components used in, on, or in association with burners.Requirements for specific operating values, operating times, and operating sequences are given in the standards for appliances and equipment.
1.1.2 Replacement:This standard applies to manual controls when such are electrically and/or mechanically integral with automatic systems.
1.1.3 Not Applicable.
1.1.4 Not Applicable.
1.1.5A Addition:
This standard applies to each component of an automatic burner ignition system shall be capable of operation throughout an ambient temperature range of 32?F (0?C) to 125?F (51.5?C). The manufacturer is allowed to specify temperatures below 32?F (0?C) and above 125?F (51.5?C).
a) For gas fired equipment rated 400,000 Btu/hr (117 228 W) or less, Tmin, and Tmax are as specified in 1.1.5A; and
b) For burner controls for all other equipment, Tmax, declared at less than 150?F (65.5?C) shall be tested at 150?F (65.5?C) or higher as specified by the manufacturer.
1.3 Not Applicable.
1.3A Addition:
Compliance with this Part 2 standard does not imply that such a control is acceptable for use on fuel burning appliances or equipment without supplemental test with the device(s) applied to the particular appliance or equipment design.
1.3A.1 All specifications as to construction set forth herein may be satisfied by the construction actually prescribed or such other construction as will provide at least equivalent performance.
1.3A.2 If a value for measurement as given in this standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.
1.4 Replacement:This standard applies also to controls incorporating electronic devices, requirements for which are contained in annex h, Requirements for electronic systems and components.
