Capacities and Specifications
Lower gas supply pressure configurations available for New York City requirements
Firing rates based on altitudes to 2000ft. above sea level.
* For firing rates at higher altitudes, consult factory.
Gas input based on natural gas at 1,000 Btu/cu.ft. and 0.60 gravity
Oil input based on 140,000 Btu/gal. on M, 145,000 Btu/gal. on MM and 150,000 Btu/gal. on ME series.
Boiler overall efficiency of 80% estimated.
* Industrial Combustion does not guarantee overall boiler efficiency.
Gas pressure based on zero furnace pressure.
* For total pressure at manifold, add furnace pressure.
Impeller and motor HP is based on altitude up to 2,000 ft. above sea level, and up to 1.5″ W.C. furnace pressure.
* For higher altitude or 50 Hz applications, consult factory.
