Product Details

Rinnai Conversion Kit Liquid Propane to Natural Gas For E110SR Boilers 803000021

The Rinnai 803000021 is a genuine OEM gas conversion kit designed to convert compatible Rinnai E-Series condensing boilers from Liquid Propane (LP) to Natural Gas (NG). This kit allows qualified technicians to safely perform a field conversion when natural gas service is available or preferred.

Specifically designed for the Rinnai E110SR (E110SRP) condensing boiler, this conversion kit provides the internal components required to reconfigure the boiler’s combustion system and gas delivery settings for natural gas operation. Once installed, the unit can operate efficiently using natural gas fuel.

The kit includes a pre-programmed EE-PROM chip that updates the boiler’s internal control parameters for natural gas combustion. A precision brass orifice is also included to regulate the correct flow and pressure of natural gas into the burner.

To ensure safe installation, the kit includes both black and yellow rubber gaskets that provide a secure, leak-resistant seal during the conversion process. In addition, replacement labeling such as a boiler rating plate and gas identification stickers are included to clearly identify the unit as a natural gas appliance after the conversion is completed.

Because gas appliance conversions require accurate calibration and combustion adjustments, the Rinnai 803000021 conversion kit should be installed by a licensed HVAC technician or qualified gas professional. Proper installation ensures safe operation and compliance with manufacturer specifications.
