A brochure is available on the RV Series forced draft gas, oil, and dual-fuel fired steam and hot water boilers. The boilers are available in eight standard sizes from 3.5 million to 8 million Btuh. All models have at least 5 square feet of heating surface per boiler horsepower. The manufacturer states the flexible water tube design eliminates the possibility of damage from so-called thermal shock. The combustion chamber, tubes, and burner head are completely accessible from one side, simplifying maintenance and minimizing floor space, the company says. Tubes are individually replaceable without welding or rolling, and there are never more than two tube configurations, the manufacturer states.
