Page 7: Boiler Description
1.1 Boiler/Water Heater Description The Gasmaster GMI 2M (2ML) is a gas-fired water tube boiler and water heater with nominal input rating of 2,000,000 Btu/hr. Each unit has five stainless steel coiled tubes (SA-249 Type 316L), 1.25” (1.50”) diameter and 0.065” wall thickness. All five coils are held parallel vertically by means of four stainless steel ready rods and adjustment nut assemblies. -
