It operates on 115-volt single-phase, 60 Hz power and delivers 82 percent thermal efficiency through an in-shot burner configuration with direct spark ignition (DSI). A power vent system handles flue gas exhaust, making placement more flexible than gravity-vent alternatives. At 195 pounds, this is a substantial suspended or wall-mounted unit intended for installation by licensed HVAC professionals in warehouses, garages, loading docks, and similar high-volume spaces.\u003c\/p\u003e\n\u003cp\u003eThis unit heater is suited for commercial and light-industrial heating applications where a high-output gas-fired suspended heater is required. The single-stage heat output provides straightforward on\/off operation appropriate for spaces that do not require modulating heat control. The open drip-proof (ODP) motor construction suits indoor environments where occasional moisture exposure is possible but direct water contact is not expected. The 10-year heat exchanger warranty provides long-term coverage on the core thermal component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e150,000 BTU\/h natural gas input for high-capacity space heating\u003c\/li\u003e\n  \u003cli\u003e82 percent thermal efficiency with in-shot burner design\u003c\/li\u003e\n  \u003cli\u003eDirect spark ignition (DSI) for reliable, pilot-free startup\u003c\/li\u003e\n  \u003cli\u003ePower vent exhaust for flexible installation positioning\u003c\/li\u003e\n  \u003cli\u003eSingle-stage operation on 115-volt, single-phase, 60 Hz power\u003c\/li\u003e\n  \u003cli\u003e10-year heat exchanger warranty\u003c\/li\u003e\n  \u003cli\u003eOpen drip-proof (ODP) motor construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM unit heater for commercial and industrial gas heating applications requiring a 150,000 BTU\/h single-stage natural gas suspended heater with power vent exhaust.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the manufacturer instructions. Shut off and lock out electrical power and close the gas supply valve before servicing or mounting. Power vent units require proper venting pipe sizing and termination per the installation manual to prevent flue gas recirculation. At 195 pounds, two-person rigging and appropriate structural support are required for safe suspended mounting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeating Capacity\u003c\/strong\u003e: 150,000 BTU\/h (150 MBH)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIgnition\u003c\/strong\u003e: Direct Spark Ignition (DSI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBurner Type\u003c\/strong\u003e: In-Shot\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVenting\u003c\/strong\u003e: Power Vent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEfficiency\u003c\/strong\u003e: 82 percent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 115 volts, Single Phase, 60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: Open Drip-Proof (ODP)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat Exchanger Warranty\u003c\/strong\u003e: 10 years\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit Weight\u003c\/strong\u003e: 195 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STERLING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: tf150a1ns111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sterling","offers":[{"title":"Default Title","offer_id":51138665906482,"sku":"TF150A1NS111","price":1073.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305531311.jpg?v=1778261456","url":"https:\/\/voomisupply.com\/products\/sterling-tf150a1ns111-unit-heater-150000-btu-h-natural-gas","provider":"Voomi Supply","version":"1.0","type":"link"}
