INSTALLATION - OIL BUW..,'=g 701j 410T (Burners, Controls, Apparatus, ate) 1. Combustion Safeguards. Each oilburner shell be provided with an approved automatic combustion safeguard which will effectively proven-c the abnormal discharge of oil in case of ignition failure or flame failure. a. Heat vaporization burners shall be provided with an approved constant level and anti- flooding device. b. Oil burners other than heat vaporization burners whose firing rate does not exceed five (5) gallons per hour shall be provided with an approved combustion safeguard device whose main burner trial- for - ignition or flame failure timing period does not exceed two (2) minutes. c. Oil burners whose firing rate exceeds five (5) gallons per hour shall be provided with an approved combustion safeguard whose main burner, trial- for - ignition timing does not exceed sixty (60) seconds, d hex- �16')"aesortde. 2. Domestic Type Rotary Vaporization Burners. Domestic Type vaporization burners which operate on the vertical rotary principal shall be pre - vided with constant level device arranged.so as to prevent an abnor- mal supply of oil to the burner. 3. Limit Controls. till oil burning equipment shall be provided with an approved means of automatically shutting off the burner when the limits of temperature and /or pressure here inafter.specified are ex- ceedod; except that this requirement shall not apply to oil fired foom heaters. In the case of a heat vaporization burner, this control may place the burner on low -flame operation. a. The setting of the limit control on a mechanical warm air furnace shall not exceed 20OF except by special permission of the Department. b. The setting of the limit control on a gravity warm air furnace shall not exceed 300F. c. The setting of the limit control on a steam boiler shall not exceed the allowable working pressure of the boiler. d. The setting of the limit control on a boiler or heater used in connection with a hot water heating or a hot water supply system shall not exceed 20OF except by special permission of the Department. 4. Low Water Fuel Cutoff. As required by the American Society of Mechanical ngineers boiler Code, a low water fuel cutoff shall be installed in accordance therewith on all oil fired steam boilers. 5. Limit Control & Low Mater Fuel Cutoff in 114ain Circuit. Limit Controls and low water fuel cutoffs which, by operating, interrupt the electric power supply to the burner shall be so arranged as to open the main line current supply to the burner, whether the switch- ing is integral with the sensing element or remote from same. 6. Combustion air - Oil Interlock. In installations equipped with forced or induced draft fans, or both, approved means shall be provided to immediately shut off the oil supply upon air supply failure. Controls actuated by failure of the power supply to the blower motor do net meet this requirement. This does not apply to heat vaporization burners listed by Underwriters' Laboratories, Inc.
