Sterling HVAC 11261R06045 Conversion Kit

The Sterling HVAC 11261R06045 Conversion Kit is a field-proven solution for transitioning natural gas to liquid propane (LP) on standing pilot equipment. This OEM gas conversion kit is engineered for a broad range of Sterling unit heaters, specifically the QV, QVS, QVB, QVD, and QVF series ranging from 100 to 250 MBH. As a specialized NG to LP conversion set, it includes high-precision main burner orifices, a specific pilot burner orifice, and the necessary gas valve conversion components to maintain manifold pressure stability. Utilizing a standing pilot conversion kit ensures that older millivolt or standard pilot systems maintain safe combustion characteristics after the fuel swap. For contractors managing HVAC fuel conversion projects, this kit provides a direct fit to Dayton and Sterling equipment, eliminating the need for generic drilling or manifold modifications. The technical conversion plate and notice of conversion label included are essential for meeting local mechanical codes and ensuring future serviceability by identifying the current gas type and orifice sizing.

• Compatible with Sterling QV100 through QV250 series and equivalent Dayton unit heaters.
• Includes 10 main burner orifices and a dedicated pilot burner orifice for complete fuel reconfiguration.
• Designed strictly for standing pilot systems; not for use with direct spark or hot surface ignition models.
• Includes official conversion labels and plates to satisfy inspection requirements and safety standards.
• Maintains OEM performance specs by providing the correct liquid propane orifice sizes for specific BTU inputs.

• How do I confirm if my unit is a standing pilot model? Check your burner assembly for a continuous pilot flame or a gas valve with an "OFF-PILOT-ON" knob. This kit is incompatible with DSI or HSI electronic ignition boards.
• What manifold pressure is required after conversion? While specific to the unit heater model, most LP conversions for these heaters require adjusting the regulator to roughly 10" W.C. Always verify with the manufacturer's technical plate.
• Can this kit be used for high-altitude applications? Standard orifices are sized for 0-2000 feet. Installations at higher elevations require further derating per the National Fuel Gas Code.
