Reznor 1036549R Conversion Kit
When you are tasked with converting a Reznor UDAP or UDAS unit heater from liquid propane (LP) to natural gas, the Reznor 1036549R Conversion Kit is the essential OEM solution for 300, 350, and 400 series models. This kit is specifically engineered to handle the high BTU demands of these large-scale warehouse and industrial heaters, ensuring the manifold pressure and thermal output align with factory benchmarks. As a technician, you know skipping a proper conversion leads to soot buildup and unstable combustion; this package includes the precise burner orifices and gas valve regulator springs (typically for Honeywell or Robertshaw valves) required for a safe, code-compliant changeover.
Installation involves removing the manifold assembly and replacing the existing LP orifices with the natural gas orifices provided. Because this kit often services multiple cabinet sizes, always verify your specific unit heater model number against the orifice markings to ensure the correct firing rate. Adjusting the manifold gas pressure to the standard 3.5" w.c. for natural gas is critical for maintaining energy efficiency and preventing heat exchanger fatigue in high-capacity Reznor HVAC systems.
Key Benefits- Precise Fuel Transition: Engineered specifically for Reznor UDAP/S 300-400 units to ensure balanced air-to-fuel ratios.
- OEM Reliability: Guaranteed fit for Honeywell and Robertshaw gas valves found in Reznor 300-400 MBH series heaters.
- Combustion Safety: Provides the correct orifice sizing to prevent over-firing and ensure clean natural gas combustion.
- Universal Application: Compatible with both standard power vent and separated combustion unit heaters within the specified size range.
Is this kit compatible with UDX or UDZ models?
Yes, the Reznor 1036549R is the correct conversion part for modern UDX and UDZ series as well as legacy UDAP and UDAS models in the 300 to 400 size bracket.
Do I need to change the burner air restrictors during this conversion?
When converting from LP to natural gas on certain 300-400 size models, any existing air restrictor plates must typically be removed to allow for the lower-density gas flow, though you must always refer to the included technical wiring and manifold diagram for your specific serial range.
What is the proper manifold pressure after installing this kit?
For standard natural gas conversions, the manifold pressure should be set to 3.5 inches water column (w.c.) to ensure the heater reaches its rated BTU input without compromising the burner assembly.
