The GC124 heat exchanger construction consists of flexible GL-180M cast iron, designed to resist thermal shock for long life and a high silicone cast iron surface for excellent corrosion resistance. Standard equipment includes high precision castings with threaded steel nipples, Honeywell aquastat, tridicator gauge, 30 psi relief valve and a circulator with a 3 inch whip and a built in draft hood with integral draft diverter. All piping connections are in the rear for a finished appearance with its deluxe, heavy gauge blue enameled jacket.
