CG-210 GeneraL
Installation requirements shall apply to controls, safety devices, and burners on automatically fired boilers covered by this Standard.
For information regarding boiler and/or burner installations. refer to local codes, in the absence of local codes. see NFPA 54/ANSI Z2231 (or gas-fired boilers and NFPA 31 for oil-fired boilers.
For boilers firing liquefied-petroleum gas or LP-gas air mixtures, the requirements pertaining to the storage container, the first and second stage LP.gas pressure regulators, and all components upstream of the point of gas delivery (see CG-700) are covered by NFPA 58.
CC-nO InstaLLation
(a) Installation of controls, safety devices, and burners shall be In accordance with the manufacturer’s Instructions and the applicable requirements of this Standard Diagrams detailing the wiring and piping connections for the controls and safety devices installed shall be turnished by the unit manufacturer [see CG-S1O(c)j.
(b) Installations shall provide accessibility for removing burners; adjusting, cleaning, and lubricating working parts; and replacing controls, safety devices. and other control components.
(c) For information concerning the location and installation of LP-gas air mixture boilers, refer to local building codes.
(d) When one or more modules of a modular boiler(see CG-700) are replaced, compatibility of all controls and systems shall be ensured. The replacement modules shall comply with the initial listing and shall meet the requirements of this Standard.
CG-230 Observation Ports
Observation ports shall be provided to permit direct visual inspection of the pilot, main burner flame, and boiler furnace, if required to adjust the pilot and/or main burner flame, Observation ports providing direct visual observation are not required for the following:
(a) boilers using pulse combustion that are labeled and listed by a nationally recognized testing agency.
(b) boilers providing indirect observation by reflection for visual observation or an indicator driven by a sensor. When used, a sensor and indicator shall display both the presence and absence of the pilot and/or main flame.
CC-240 Guarding
Guards shall be provided to protect personnel and protect against damage to control equipment. Guarding shall conform to applicable regulations.
drip: the container placed at a low point in a system of piping to collect condensate and from which condensate may be removed.
fan, forced draft: a fan used to supply air, under pressure, to the fuel-burning equipment of the boiler.
fan, induced draft: a fan used to exhaust gases, under suction, from the boiler.
feedback line: a section of piping or tubing that normally communicates air pressure from a point of reference to the air pressure side of a diaphragm of fuel train component. hut could contain gas under abnormal conditions; or a section of piping or tubing that communicates flue or gas pressure from one point of reference to another point of reference.
firing rate: the rate at which air, fuel, oran air-fuel mixture is supplied to a burner, expressed in volume or heat units supplied per unit of time.
ft ame failure response time: the time interval between the loss of flame and deenergizing the safety shutoff valve.
flue passages (breeching): the cavities (e.g., flue, exhaust, or vent system) that convey the products of combustion from the boiler combustion chamber to an approved location.
FM: factory mutual approvals.
fuel train: a series of valves, regulators, and controls, between the burner and the source of fuel, that regulates and controls the flow of fuel to the burner.
gas: one of the following fuel gases: natural gas, liquefied petroleum (LP) gas, LP—air mixture, manufactured gas, or mvced gas.
gas-pressure regulator, pilot: a device for controlling and maintaining a predetermined gas pressure for the pilot burner.
gas-pressure relief line: a section of pipe or tubing that conveys a release of gas from a gas-pressure relief valve.
ground: a conducting connection, whether intentional or accidental, between an electrical circuit or equipment and either the earth or a conducting body that serves in place of the earth.
grounded: connected to earth or to some conducting body that serves in place of the earth.
grounded conductor: a system or circuit conductor that is intentionally grounded.
