The G234X and G334X 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. They each have staggered contoured fins for optimum heat transfer and efficient operation, high precision castings with steel push nipples, sectional construction, and deluxe, heavy gauge blue enameled jacket for a clean finished appearance. There is a full 3" of thermal insulation for minimal standby heat loss coupled with an integral draft diverter for low profile. All models are easily converted to propane, and they also offer low emissions with Premixed Burner Technology.
