Reznor 269851 Conversion Kit

Professional-grade Reznor 269851 LP to Natural Gas conversion requires precise components to maintain manifold pressure and unit efficiency. This technician-ready conversion kit is engineered specifically for Reznor UDAP and UDAS series unit heaters, covering 030 and 045 input sizes. When transitioning fuel sources, achieving the correct orifice size and spring tension is critical for preventing soot accumulation or delayed ignition. This kit includes the necessary main burner orifices and the specific natural gas regulator spring (often the #393691 for single-stage VR8205 series valves) required to reconfigure the gas valve. By switching from liquid propane back to natural gas, contractors can optimize the unit heater performance while ensuring the appliance operates within manufacturer-specified manifold pressure limits (typically 3.5" w.c.). This HVAC fuel conversion package provides the exact mechanical components needed for field modification, ensuring compatible threads and flow rates for reliable HVAC repair and maintenance in commercial or residential garage applications.

• Specifically calibrated for Reznor unit heater models UDAP 30, UDAP 45, UDAS 30, and UDAS 45.
• Ensures accurate manifold pressure regulation for natural gas combustion.
• Includes high-tolerance burner orifices to maintain proper BTU input ratings.
• Facilitates a clean fuel transition without needing to replace the entire gas valve assembly.
• Designed to meet strict safety standards for HVAC gas fuel conversion.

Which heater models are compatible with this kit?
This Reznor conversion kit is designed for UDAP and UDAS power-vented and separated combustion models in the 30,000 and 45,000 BTU sizes. Always verify the serial number on your gas valve (such as Honeywell or White-Rodgers) before installation.

Does this kit include the air restrictor plate?
When converting from LP to natural gas on these smaller units, the air restrictor plate is typically removed. This kit provides the necessary spring kit and orifices to complete the process per the manufacturer's technical instructions.

Can I use this for high-altitude installations?
While this kit handles the standard fuel conversion, high-altitude adjustments (typically above 2,000 feet) may require additional de-rating or specific orifice sizing. Consult the official Reznor pressure tables for your specific elevation.
