R020932J1, Install Manual

STEAM GENERATOR & FLUID HEATER INSTALLATION MANUAL

Gas pressure regulation is required. A regulated minimum of 2 psi gas pressure is required at the inlet to the gas train. Pressure regulators should be sized to pass 25% excess gas at full open position with minimal pressure drop. One-eighth inch vent lines are needed for both the high and low gas pressure switches.

NOTE Refer to local codes regarding vent manifolding.

4.3 OIL 4.3.1 General Clayton SigmaFire oil-fired steam generators are step-fired and designed with pressure atomiz- ing-type oil burners. A 0.5–10 psig fuel oil pressure is required at the inlet to the fuel oil pump.

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 distillate light fuel oil as defined by ASTM D 396 - Standard Specifications for fuel oils.

NOTE A fusible-link-actuated shutoff valve is required in the fuel oil supply line when a machine is installed within FM (Factory Mutual) jurisdiction. This is not within the Clayton scope of supply and must be provided by the installer.

A Clayton step-fired light-oil fuel system uses a direct-fire ignition.
