They may be used where a competent attendant will not be
23、 constantly on duty in the room where the appliance is located, while the appliance is in operation. They are required to be equipped with automatic primary safety controls to prevent abnormal discharge of oil at the burner in case of ignition failure or ame failure. They are not intended for use in
24、 spaces in which ammable vapors or gases may be present. 1.2 Requirements for the installation and use of oil-burning equipment are included in the Standard of the National Fire Projection Association for the Installation of Oil-Burning Equipment, NFPA No. 31. 1.3 A product that contains features, c
25、haracteristics, components, materials, or systems new or different from those covered by the requirements in this Standard, and that involves a risk of re, electric shock, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements to determine tha
26、t the level of safety as originally anticipated by the intent of this Standard is maintained. A product whose features, characteristics, components, materials, or systems conict with specic requirements or provisions of this Standard shall not be judged to comply with this Standard. Where appropriat
27、e, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this Standard. 1.3 revised November 17, 1999 2 Components 2.1 Components of an oil burner, except as specied herein, or a gas burner as well as burner a
28、nd stove accessories such as constant-level oil valves, metering valves, re pots, etc.; electrical components and materials such as attachment plugs, industrial control equipment, switches, transformers, electrically operated valves, wires, etc.; and other components or parts shall comply with the r
29、equirements for those components, except that such requirements may be modied if appropriate for the particular application. 3 Units of Measurement 3.1 If a value for measurement is followed by a value in other units in parentheses, the second value may be only approximate. The rst stated value is t
30、he requirement. 4 Glossary 4.1 AIR SHUTTER An adjustable device for varying the size of the air inlet or inlets regulating primary or secondary air. 4.2 ANTIFLOODING DEVICE A primary safety control which causes the fuel ow to be shut off upon a rise in fuel level or upon receiving excess fuel, and w
31、hich operates before the hazardous discharge of fuel can occur. 4.3 APPLIANCE FLUE The ue passages within the appliance. 4.4 AUTOMATICALLY LIGHTED APPLIANCE An appliance in which fuel to the main burner is normally turned on and ignited automatically. 4.5 BAFFLE An object placed in an appliance to d
32、irect or to retard the ow of air of ue gases. NOVEMBER 17, 1999 OIL-BURNING STOVES - UL 896 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 4.6 BASE The main supporting frame or structure of an assembly. 4.7 BURNER A device for the nal conv
33、eyance of fuel or a mixture of fuel and air to the combustion zone. 4.8 BURNER, MECHANICAL-ATOMIZING TYPE A power-operated burner which prepares and delivers the oil and all or part of the air by mechanical process in controllable quantities for combustion. Some examples are air atomizing, high- and
34、 low-pressure atomizing, horizontal rotary, vertical rotary atomizing, and vertical rotary wall-frame burners. 4.9 BURNER, MECHANICAL-DRAFT TYPE A burner which includes a power-driven fan, blower, or other mechanism as the principal means for supplying air for combustion. 4.10 BURNER, NATURAL-DRAFT
35、TYPE A burner which depends principally upon the natural draft created in the ue to induce into the burner the air required for combustion. 4.11 BURNER, VAPORIZING TYPE A burner consisting of an oil-vaporizing bowl or other receptacle to which liquid fuel may be fed in controllable quantities; the h
36、eat of combustion being used to vaporize the fuel, with provision for admitting air and mixing it with the oil vapor in combustible proportions. 4.12 CASING An enclosure forming the outside of the appliance, no parts of which are likely to be subjected to intense heat. 4.13 COMBUSTIBLE CONSTRUCTION
37、As pertaining to materials adjacent to or in contact with heat producing appliances and ue pipes, steam pipes, and warm air ducts connected thereto, combustible construction shall mean structures made of or surfaced with wood, compressed paper and plant bers, or other material that will ignite and b
38、urn, whether plastered or unplastered. Plastered construction having combustible supports, regardless of the type of lath employed, and gypsum or other wallboard surfaced with combustible material, are classied as combustible construction. 4.14 COMBUSTION As used herein, the rapid oxidation of fuel
39、accompanied by the production of heat, or heat and light. Complete combustion of a fuel is possible only in the presence of an adequate supply of oxygen. 4.15 COMBUSTION CHAMBER The portion of an appliance within which combustion occurs and which is usually part of the heat exchanger. 4.16 CONSTANT-
40、LEVEL VALVE A device for maintaining within a reservoir a constant level of fuel for delivery to the burner. 4.17 CONTROL A device designed to regulate the fuel, air, water, or electrical supply to the controlled equipment. It may be automatic, semi-automatic, or manual. 4.18 CONTROL, LIMIT An autom
41、atic safety control responsive to changes in liquid level, pressure, or temperature; for limiting the operation of the controlled equipment. 4.19 CONTROL, PRIMARY SAFETY The automatic safety control intended to prevent abnormal discharge of oil at the burner in case of ignition failure or ame failur
