Description / Abstract:

These requirements apply to field assembled boiler assemblies that are provided with or are intended for installation with single fuel-gas, single fuel-oil, or combination gas-oil burning equipment.

These requirements apply to fuel burning equipment which require flame failure and other safeguards and which are intended primarily for commercial and industrial installation.

Equipment covered by these requirements may be operated without a competent attendant being constantly on duty at the equipment while the burners are in operation.

The appliance shall be suitable for installation in accordance with the Standards for Installation of Oil-Burning Equipment, NFPA 31, and/or National Fuel Gas Code, NFPA 54, and the National Electrical Code, NFPA 70-1993.

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 fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-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 conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.

Equipment covered by these requirements shall be designed, assembled, tested, and inspected in accordance with the requirements of Section I or Section IV of the ASME Boiler and Pressure Vessel Code. Conformance with the code will be determined by application of the ²H or ²S ² stamp and, if applicable the ²A ² symbol stamp on the appropriate part of the boiler assembly.

Each field erected boiler shall undergo a final inspection following completion of field assembly, ASME code required testing and inspection, and operational testing. The inspection shall cover all points required by the authority having jurisdiction.
