Example text

2. Class I Locations. Class I locations are those locations in which flammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures. a. Class I, Division 1 Locations. These are Class I locations where the hazardous atmosphere is expected to be present during normal operations. It may be present continuously, intermittently, periodically, or during normal repair or maintenance operations. Division 1 locations are also those locations where a breakdown in the operation of processing equipment results in the release of hazardous vapors while providing a source of ignition with the simultaneous failure of electrical equipment.

C. Divide the total heat loss by 10,000 to obtain the total pump capacity in GPM. D. Select a circulating pump to provide the total required GPM and obtain the head created at this flow. E. Multiply the head by 100 and divide by the total length of the longest run of the hot water return piping to determine the allowable friction loss per 100 feet of pipe. F. Determine the required GPM in each circulating loop and size the hot water return pipe based on this GPM and the allowable friction loss as determined above.

F. Bidder. An individual, firm, partnership, corporation, joint venture, or any combination thereof submitting a Bid for the Work as a single business entity and acting directly or through a duly authorized representative. G. Authority Having Jurisdiction. The term authority having jurisdiction shall mean federal, state, and/or local authorities or agencies thereof having jurisdiction over Work to which reference is made and authorities responsible for “approving” equipment, installation, and/or procedures.
