Organization: UL
Publication Date: 11 February 1994
Status: active
Page Count: 94
scope:

These requirements cover primary safety controls for gas, gas-oil, and oil-fired appliances. These safety controls are intended to sense the presence or absence of flame and, in the event of ignition failure or unintentional flame extinguishment, cause safety shutdown.

These requirements are not intended to include those primary safety controls for gas appliances that are of the type intended primarily for use with gas appliances having inputs of 400,000 Btu per hour (120 kW) or less per individual combustion chamber.

Requirements for the installation and use of primary safety controls are included in Standards of the National Fire Protection Association, such as those for the installation of:

Oil-Burning Equipment, ANSI/NFPA 31-1987,

National Fuel Gas Code, NFPA 54, ANSI Z223.1-1988,

Ovens and Furnaces, ANSI/NFPA 86-1990, and

Furnace Explosions/Implosions in Multiple Burner Boiler-Furnaces, ANSI/NFPA 85C-1991.

Requirements for the installation of oil-burning equipment are included in codes such as:

The BOCA National Mechanical Code,

The Standard Mechanical Code, and

The Uniform Mechanical Code.

A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
