Rated at 55,000 BTU\/h and 95% AFUE, it modulates deeply so it can match a small load without short-cycling, which is exactly where oversized boilers waste fuel. The low-NOx burner meets strict emissions requirements, and direct-vent sealed combustion allows PVC or polypropylene venting through a sidewall with no chimney. It is heating-only, so it pairs with an indirect tank when domestic hot water is needed, and it runs on natural gas or propane. The 24 in. by 24 in. cabinet mounts indoors on the wall and operates on standard 120V power. ENERGY STAR qualified; installation by a licensed gas heating contractor is required.\u003c\/p\u003e\u003ch3\u003eAt a glance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e55,000 BTU\/h input with 95% AFUE condensing efficiency\u003c\/li\u003e\n\u003cli\u003eDeep modulation for small, low-heat-loss spaces\u003c\/li\u003e\n\u003cli\u003eLow-NOx burner meets strict emissions requirements\u003c\/li\u003e\n\u003cli\u003eHeating-only design, pairs with an indirect DHW tank\u003c\/li\u003e\n\u003cli\u003eDirect-vent sealed combustion, no chimney required\u003c\/li\u003e\n\u003cli\u003eNatural gas or propane operation\u003c\/li\u003e\n\u003cli\u003eCompact 24 in. indoor wall-mount cabinet\u003c\/li\u003e\n\u003cli\u003eENERGY STAR qualified, 120V electronic ignition\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecification\u003c\/h3\u003e\u003ctable class=\"product-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eNavien\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eh_feceb71\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eBoiler\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInput\u003c\/th\u003e\n\u003ctd\u003e55 MBH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower source\u003c\/th\u003e\n\u003ctd\u003ePropane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCondition\u003c\/th\u003e\n\u003ctd\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp class=\"product-disclosure\"\u003eOutdoorSupply is an independent retailer.
