The Cyclone Xi features power-vent and power direct vent design, allowing combustion air to be drawn from the
equipment room conventionally or directly from the outdoor atmosphere through a sealed intake air pipe.
Vent systems can be terminated vertically through the ceiling or horizontally through a sidewall.
*Chart applies to BTH-120 through BTH-250 models only.
*4˝ PVC required on BTH-300 through BTH-500 for up to 70 equivalent feet of venting.
6” PVC Required for longer installations

Revolutionary Heat Exchanger And Burner Systems
The internal helical heat exchanger keeps the hot flue gasses
inside the heater longer, producing an extra-high rate of heat
transfer, resulting in higher thermal efficiency. All Cyclone Xi
models employ an ingenious top-mounted down-fire pre-mix
burner, resulting in even higher efficiencies.
