It delivers supplemental or primary space heating without any flue or venting requirement, making it practical for rooms where duct or venting work is not feasible. The unit operates at 99.9% thermal efficiency, and its standing pilot ignition with push-button piezo start keeps it fully functional during power outages. A factory-installed Oxygen Depletion Sensor (ODS) automatically shuts the unit off before oxygen levels drop to an unsafe concentration. Installation and service must be performed by a certified gas technician.\u003c\/p\u003e\n\u003cp\u003eThe HRW25ML is suited for residential and light-commercial applications where supplemental zone heating is needed without electrical dependency. It ships with a wall-mount kit included; an optional floor stand is available separately. The unit is available in a white finish and is offered in LP only. A thermostatic-control version is available under model HRW25TL. An optional blower can be added for improved air circulation. LP installations require a 100-pound or larger propane tank and an external regulator providing an output of 11 to 14 inches water column (w.c.). This product cannot be shipped to the state of California.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e25,000 BTU\/h infrared and radiant heat output with 99.9% thermal efficiency\u003c\/li\u003e\n  \u003cli\u003eVent-free design eliminates flue or chimney requirements\u003c\/li\u003e\n  \u003cli\u003eOxygen Depletion Sensor shuts off heater before oxygen reaches an unsafe level\u003c\/li\u003e\n  \u003cli\u003eStanding pilot with push-button piezo ignition operates without electrical power\u003c\/li\u003e\n  \u003cli\u003eWall-mount kit included; optional floor stand and blower sold separately\u003c\/li\u003e\n  \u003cli\u003eEvery unit is test-fired at the factory before shipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with liquid propane gas supply only.
