CG-200 GENERAL PROVISIONS CG-210 General Provisions Installation requirements shall apply to controls, safety devices, and burners on automatically fired boil- ers 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 Z223.1 for gasfired 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, Liquefied-Petroleum Gas Code. CG-220 Installation
(a) Installationofcontrols, safetydevices,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 furnished by the unit manufacturer [see CG-510(c)].
(b) Installations shall provide accessibility for removing burners; adjusting, cleaning, and lubricating work- ing 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
CG-240 Guarding Guards shall be provided to protect personnel and protect against damage to control equipment. Guarding shall conform to applicable regulations.
CG-250 Annunciator Systems Where used, annunciator systems, and their associ- ated test and acknowledgement circuits, shall have all contacts, switches, relays, and lights arranged so that safety control functions are not bypassed.
CG-260 Combustion Air
(a) The requirements of combustion air shall be in accordance with NFPA 54/ANSI Z223.1, National Fuel Gas Code, for gas-fired boilers and with NFPA 31,
Standard for the Installation of Oil-Burning Equipment, for oil-fired boilers.
(b) Louvers and grilles shall be fixed in the open posi- tion or interlocked with the equipment so that they are opened automatically during equipment operation.
The interlock shall be placed on the driven member.
(c) Fans supplying air to the boiler room for combus- tion shall be interlocked with the burner so that air flow is proven during equipment operation. CG-300 MATERIAL REQUIREMENTS CG-310 Components Each control and safety device covered by this Standard shall be accepted for the intended service by a nationally recognized testing agency such as, but not limited to, UL, FM, or
CSA. CG-400 TESTING AND MAINTENANCE CG-410 Cleaning Manufacturers of controls and safety devices requir- ing periodic service shall furnish detailed instructions covering the procedures and frequency of cleaning [see CG-510(c)].
CG-420 Testing Manufacturers of boilers and burners covered by this Standard shall furnish detailed instructions for testing controls and safety devices, both when the boiler is operating and when it is out of service [see CG-510(c)].
CG-430 Maintenance Boiler, boiler unit, and burner manufacturers shall furnishdetailedinstructions onmaintenance andservice procedures for the fuel burning system or electrically heated units, including controls and safety devices installed with the unit. These instructions shall include requirements speci- fying that cover plates, enclosures, and guards shall be maintained in place at all times, except during mainte- nance (see CG-510 and Part CM). Boiler, boiler unit, burner, and control manufacturers’ operation and maintenance instructions furnished with the equipment shall be retained and made available to the boiler operator (see CG-510).
CG-440 Operational Testing The operation of control systems and safety devices installed in accordance with this Standard shall be tested by the installing contractor prior to release to the owner/user.ASME CSD-1 pdf download.ASME CSD-1-2009 pdf free download
