Description
FTXL boilers have a top-mounted, micro-metal fiber burner, with a blower/gas valve assembly that drives heat energy downward, through stainless steel fire tubes, with exhaust venting through the bottom of the unit. With up to 10:1 modulation turn-down, the burner automatically changes its firing rate as building heat loads vary. An FTX1000 fires at its maximum 999,000 Btu/hr rate when heat load is highest, then gradually “turns down” to as low as 10% (99,900 Btu/hr) as load decreases. A modulating system runs smoothly and efficiently, without frequent on/off cycling.
