premium noncondensing oil- and gas-fired cast-iron water boilers. The new
oil-fired boilers have a unique three-pass cast-iron heat exchanger, designed
to resist thermal stress, maximize heat transfer and deliver Energy
Star®-qualified efficiency performance with up to 86.7 percent AFUE. A
customized Riello burner is finely tuned to optimize combustion.
The American Standard gas-fired boilers have
single-pass design, maximizing heat transfer and fuel efficiency up to 84.3
