STEAM GENERATOR & FLUID HEATER INSTALLATION MANUAL

Vent lines are required for both the high and low gas pressure switches (1/8 inch) and vent valve (size varies with model - see generator P & ID drawing by specific model number.)

NOTE Some gas trains are ventless. But, when gas train vent lines exist, they must be vented to atmosphere.

NOTE All gas supply piping must include a minimum 12-inch drip leg immediately before Clayton’s gas train connection, and be fully self-supporting.

4.3 OIL 4.3.1 General

Clayton modulating, oil-fired, steam generators are designed with air atomizing-type oil burners. Either instrument air or compressed air is used for oil atomization. This air supply must be free of con- taminants and moisture; therefore, an in-line air dryer should be installed in the atomizing air supply line. Atomizing air supply pressure and flow requirements are provided in Table 1 of Section VI. The atomiz- ing air supply connection size for all models is 1/2 inch.

NOTE All Clayton liquid fuel systems require a fuel return line in addition to the fuel supply line. Clayton recommends fuel return lines have no isolation valve, or only valves with position open locking mechanisms.

NOTE It is the customer’s responsibility to implement and meet state, local and EPA code requirements for fuel oil storage.

4.3.2 Light Oil The Clayton light oil burner is designed for operation with No. 2 fuel oil as defined by ASTM D 396 - Standard Specifications for Fuel Oils. A Table of Specifications indicating the limits of the light oil fuel constituents and characteristics is provided, refer to Document R-8751 (Heavy Oil Specifications) at the end of Supplement III of this manual.
