The fire tube heat exchanger and 4.5 gallon water volume smooth out temperature swings in radiant floor and baseboard systems, and the burner modulates deep enough to keep the unit running steadily on mild days rather than short-cycling. At 95% AFUE with direct-vent sealed combustion, it vents through a sidewall in PVC, CPVC or polypropylene and needs no chimney. The boiler runs on natural gas or propane, mounts on the wall in a 33-1\/2 in. tall by 17-3\/10 in. deep cabinet, and is ENERGY STAR qualified and suitable for residential and light commercial work. Installation must be performed by a licensed gas heating contractor.\u003c\/p\u003e\u003ch3\u003eAt a glance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e175,000 BTU\/h input, 95% AFUE condensing combi-boiler\u003c\/li\u003e\n\u003cli\u003e5.4 GPM domestic hot water with 15:1 turndown\u003c\/li\u003e\n\u003cli\u003eFire tube heat exchanger with 4.5 gal water volume\u003c\/li\u003e\n\u003cli\u003eDirect-vent sealed combustion, sidewall or vertical venting\u003c\/li\u003e\n\u003cli\u003eNatural gas or propane operation\u003c\/li\u003e\n\u003cli\u003eResidential and light commercial applications\u003c\/li\u003e\n\u003cli\u003eENERGY STAR qualified with electronic ignition\u003c\/li\u003e\n\u003cli\u003eWall-mount cabinet, 33-1\/2 in.
