Requirements for the installation of oil-burning equipment are also included in codes such as the International Mechanical Code and the Uniform Mechanical Code. 1.2 revised October 1, 2008
26、1.3 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 re or of electric shock or injury to persons shall be evaluated using appropriate additional component and en
27、d-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 conict with specic requirements or provisions of this standard does not comply with this standard. Revision of
28、 requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard. 2 General 2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 3 Glossary 3.1 F

31、bject placed in an appliance to direct the ow of air or ue gases. 3.7 BASE The main supporting frame or structure of the furnace, exclusive of legs. 3.8 BURNER A device for the nal conveyance of fuel and air to the combustion zone. 3.9 BURNER, MANUALLY LIGHTED A burner in which fuel to the main burn
32、er is turned on only by hand and ignited under supervision. OCTOBER 1, 2008 OIL-FIRED FLOOR FURNACES - UL 729 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 3.10 BURNER, MECHANICAL ATOMIZING A power-operated burner that prepares and delive
33、rs the fuel and all or part of the air by mechanical process in controllable quantities for combustion. Some examples are air atomizing, high- and low-pressure atomizing, horizontal and vertical rotary atomizing, and vertical rotary wall-ame burners. 3.11 BURNER, MECHANICAL DRAFT A burner that inclu
34、des a power-driven fan, blower, or other mechanism as the principal means for supplying air for combustion. 3.12 BURNER, NATURAL DRAFT A burner that principally depends upon the natural draft created in the ue to induce into the burner the air required for combustion. 3.13 BURNER, VAPORIZING A burne
35、r consisting of a fuel-vaporizing bowl or other receptacle to which liquid fuel may be fed in controllable quantities; the heat of combustion is used to vaporize the fuel, with provision for admitting air and mixing it with the fuel vapor in combustible proportions. 3.14 CASING An enclosure forming
36、the outside of the appliance, no parts of which are likely to be subjected to intense heat. 3.15 CENTRAL HEATING APPLIANCE A stationary indirect-red vented appliance comprising the following categories: boilers, central furnaces, oor furnaces, and recessed heaters. A oor mounted unit heater to be co
37、nnected to a duct system is categorized also as a central heating appliance. 3.16 CHIMNEY CONNECTOR The pipe that connects a solid or liquid fuel-burning appliance to a chimney. 3.17 COMBUSTIBLE MATERIAL Combustible material as pertaining to materials adjacent to or in contact with heat-producing ap
38、pliances, chimney connectors and vent connectors, refers to material made of or surfaced with wood, compressed paper, plant bers, or other material that will ignite and burn. Such material is to be considered as combustible even though ameproofed, re-retardant treated, or plastered. 3.18 COMBUSTION
39、The rapid oxidation of fuel accompanied by the production of heat or heat and light. 3.19 COMBUSTION CHAMBER The portion of an appliance within which combustion occurs. 3.20 COMBUSTION (FLAME) SAFEGUARD A safety combustion control. 3.21 CONSTANT LEVEL VALVE A device that maintains a constant level o
40、f fuel in a reservoir for delivery to the burner. 3.22 CONTROL A device intended to regulate the fuel, air, water, or electrical supply to the controlled equipment. It may be automatic, semiautomatic, or manual. 3.23 CONTROL, LIMIT An automatic safety control responsive to changes in liquid level, p
41、ressure, or temperature, for limiting the operation of the controlled equipment. 3.24 CONTROL, SAFETY An automatic control, including a relay, switch, or other auxiliary equipment used in conjunction therewith to form a safety control system that is intended to reduce the likelihood of operation of
42、the controlled equipment that may result in a risk of re or injury to persons. 3.25 CONTROL, PRIMARY SAFETY An automatic safety control intended to reduce the likelihood of abnormal discharge of fuel at the burner in case of ignition failure or ame failure.
