Operating without a flue or chimney connection, it delivers 99.9% fuel efficiency by keeping all combustion heat in the conditioned space. The unit runs on a standing pilot with manual control and is suited for supplemental or primary zone heating in residential or light commercial applications. A built-in Oxygen Depletion Sensor (ODS) continuously monitors oxygen levels and automatically shuts the heater off if levels fall below a safe threshold. Wall mounting hardware is included; an optional floor stand is available separately.\u003c\/p\u003e\u003cp\u003eThis heater is intended for use in rooms where a flue connection is impractical or not available. Standard installation is wall mount, though the optional floor stand allows freestanding placement. A blower accessory is available separately to improve warm-air circulation throughout the space. The HRW18MN is rated for natural gas only and comes in a white finish. A thermostatic-control version of this unit, the HRW18TN, is also available. Professional installation by a certified gas technician is required, and all repairs must be performed by a qualified service contractor.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18,000 BTU infrared and radiant heat output with vent-free, 99.9% efficiency operation\u003c\/li\u003e\n\u003cli\u003eBuilt-in ODS shuts off the unit automatically when oxygen levels drop to an unsafe level\u003c\/li\u003e\n\u003cli\u003eStanding pilot ignition with manual control for straightforward, reliable operation\u003c\/li\u003e\n\u003cli\u003eWall mount kit included; optional floor stand and blower available separately\u003c\/li\u003e\n\u003cli\u003eNatural gas fuel type with a 3\/8-inch gas connection\u003c\/li\u003e\n\u003cli\u003eAHRI certified and Design Certified for verified performance standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for natural gas supply systems in residential and light commercial settings.
