It delivers 150,000 BTU\/h input using natural gas and operates on a 115\/1\/60 volt supply. The unit achieves 83 percent thermal efficiency through an aluminized steel tubular heat exchanger paired with in-shot burner technology. A single-stage gas control and direct spark ignition system handle combustion sequencing. An integral power venter and combustion air pressure switch are built in. Licensed HVAC technicians and mechanical contractors are the intended installers for this type of equipment.\u003c\/p\u003e\n\u003cp\u003eThis unit heater is rated for elevations from 0 to 4,999 feet and is suited for warehouses, garages, manufacturing facilities, and similar commercial or light commercial spaces. A key design feature is convertible venting: the xf150a1ns111 ships ready for either standard combustion venting or separated combustion venting without any field modification to the unit. Separated combustion venting is recommended in environments with dust, high humidity, mildly corrosive conditions, or slightly negative building pressures. The unit ships with individually adjustable and removable horizontal louvers for directional airflow control and mounts via a 2-point suspension system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e150,000 BTU\/h natural gas input with 83 percent thermal efficiency\u003c\/li\u003e\n  \u003cli\u003eConvertible venting: standard combustion or separated combustion without unit modification\u003c\/li\u003e\n  \u003cli\u003eAluminized steel tubular heat exchanger with in-shot burner technology\u003c\/li\u003e\n  \u003cli\u003eODP (Open Drip Proof) propeller motor with integral overload protection\u003c\/li\u003e\n  \u003cli\u003eDirect spark ignition and high-limit switch for reliable, safe operation\u003c\/li\u003e\n  \u003cli\u003e20-gauge steel cabinetry with baked enamel finish and isolated control panel\u003c\/li\u003e\n  \u003cli\u003e10-year warranty on heat exchanger, burner, and flue collector\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM unit heater for commercial and light commercial gas heating systems requiring a propeller-type, tubular heat exchanger configuration rated for natural gas service at low-to-moderate elevations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed HVAC or mechanical contractor in accordance with local mechanical codes, the IFGC, and the manufacturer installation instructions. Shut off the gas supply and disconnect electrical power before servicing or making any field connections. When configuring for separated combustion, connect combustion air piping to the rear inlet collars as specified in the installation manual. Verify venting material and configuration comply with local code requirements before startup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Capacity\u003c\/strong\u003e: 150,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThermal Efficiency\u003c\/strong\u003e: 83 percent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSupply Voltage\u003c\/strong\u003e: 115\/1\/60 (115 volts, single phase, 60 Hz)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Control Stages\u003c\/strong\u003e: 1 Stage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: ODP (Open Drip Proof) Propeller Motor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat Exchanger Material\u003c\/strong\u003e: Aluminized Steel Tubular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCabinet Material\u003c\/strong\u003e: 20-Gauge Steel with Baked Enamel Finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIgnition Type\u003c\/strong\u003e: Direct Spark\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVenting Type\u003c\/strong\u003e: Standard or Separated Combustion (convertible)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElevation Rating\u003c\/strong\u003e: 0 to 4,999 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: 2-Point Suspension\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat Exchanger Warranty\u003c\/strong\u003e: 10 years\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: xf150a1ns111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sterling","offers":[{"title":"Default Title","offer_id":51138783150386,"sku":"XF150A1NS111","price":1599.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305531114.jpg?v=1778263325","url":"https:\/\/voomisupply.com\/products\/sterling-xf150a1ns111-gas-unit-heater-150000-btu-h","provider":"Voomi Supply","version":"1.0","type":"link"}
