The work involves responsibility for operating and repairing automatic steam-producing boilers as well as performing steamfitting and plumbing installation and repairs. Under the general supervision of a Power Plant Supervisor, an employee in this class is responsible for the safe and efficient operation of automatic high pressure steam-producing boilers, auxiliary and associated equipment at the Department of Long Term Care, Department of Corrections or the Onondaga County District Heating and Cooling Plant. The boilers may be of either the fire tube or water tube design, powered by fuel, oil or gas. Internal pressures of the various boilers range from 15 to 250 pounds per square inch. An incumbent in this class also performs various plumbing and steamfitting tasks involving replacement, repair or installation of pipes, fittings and fixtures of water, drainage and steam heating systems. Lay out is generally provided by a higher level employee. Although there may be Boiler Operators assigned to the Power Houses to monitor the boiler operation, the Boiler/Maintenance Worker must be on call during the entire shift to return immediately to the Power House from any building maintenance task to perform both routine and emergency repairs to the operating boilers or auxiliary equipment such as pumps, compressors, and motors. Work is periodically reviewed by a higher level employee through visual, performance and other checks. Supervision may be exercised over a small number of Boiler Operators and Power Plant Workers. Does related work as required.




Monitors visually gauges and meters on boilers, water tanks, fuel tanks, air compressors, turbine generators and other auxiliary equipment for proper boiler flame level and proper level, pressure and flow of water, steam and fuel (i.e. oil or gas), using standard operating procedure and one's own knowledge and judgment to determine safe and efficient operation of equipment.

Corrects routine malfunction of boilers or auxiliary equipment such as water pumps, fuel pumps and air compressors and water and fuel tank, by manipulating valves to adjust boiler flame level and the level, flow or pressure of fuel or water.

Removes boiler water sample and applies standard predesigned chemical tests by adding reagents and observing the results; based upon manufacturer's instructions and the chemical test results, determines the amount of solids, the alkalinity and hardness of the water in the boiler; and based upon the findings, adds the pre-determined amount of chemical compounds such as caustic soda, sulfite or phosphates to the boiler-fed water to correct water condition.

May oversee the participation of Boiler Operators and Power Plant Workers in monitoring the operation of boilers and auxiliary equipment, diagnosis and correction of routine equipment malfunctions, and performing standard chemical tests on boiler water.

Performs plumbing, steamfitting and electrical repair tasks on boilers and auxiliary boiler room equipment. That is, repairs and replaces water and steam pipes, gaskets, valves; repacks and reseats water and steam valves; replaces electrical contacts, relays, fuses; may rewire mechanism.

Performs preventative maintenance tasks on boilers and auxiliary and associated equipment; such as oiling and greasing machine parts, changing belts, nuts, bolts; repairs ruptures in hoses.

Repairs, maintains and installs plumbing lines, fixtures and appliances such as sinks, tubs, showers, toilets, drinking fountains, dishwashers and various team equipment used in laundries, kitchens and cafeterias. That is, repairs, replaces and rebuilds water pipes, appliances and parts such as pumps, motors, valves, faucets, traps, sewers, vents, and sink and toilet bowls. Replaces washers and leaky faucets. Unplugs toilets, drains and pipes with hand tools and power tools.

Installs, alters and repairs high and low pressure pipe systems that carry water, steam, air or other liquids or gases. Replaces corroded or leaking pipe; lays new pipe or steam line. Adjusts, cleans, reseats, repacks, rebuilds and replaces parts on steam pressure reducing valves, temperature reducing valves and steam traps.

According to plan measures, cuts, threads and bends pipe to required angle. Assembles and installs a variety of metal and non-metal pipe and pipe fittings. Joins piping by means of threaded, caulked, wiped, soldered, brazed, fused or cemented joints. Tests pipe systems for leaks by filling with liquid or air and reading pressure gauges. May weld holding fixtures to steel members.

May make visual, audial, and tactile inspections to detect malfunctions in commercial heating, ventilation, and air conditioning equipment and tell supervisor of same in order that service contractor is notified that service is needed.

May perform simple preventative maintenance tasks to commercial heating, ventilation, and air conditioning equipment, such as visually checking fluid levels, hot water pressure; adjusting thermostats, tightening fan belts.
