Description
The Rinnai 104000012 is an OEM replacement Electrode Flame Rod and Gasket Kit designed to restore proper ignition and flame-sensing performance in compatible Rinnai appliances. Replacing a worn or failed flame rod and gasket is a critical step in maintaining safe, efficient burner operation — and using a genuine Rinnai kit ensures a precise fit and reliable long-term performance.
Product Overview
This kit bundles the flame rod electrode and the associated gasket into a single, convenient package. The flame rod serves as the primary flame-sensing component, confirming burner ignition to the appliance’s control system. The included gasket provides a proper seal at the electrode mounting point, preventing combustion gas leakage and maintaining system integrity.

Application
This kit is intended for qualified HVAC/R technicians and service professionals performing maintenance or repair on compatible Rinnai units. Always verify compatibility with the specific Rinnai model being serviced before installation. Refer to the appliance service manual for proper installation procedures and torque specifications.
Why Replace the Flame Rod and Gasket?
Over time, flame rods can develop carbon buildup or oxidation that impairs their ability to detect a flame signal, leading to nuisance lockouts or unsafe burner conditions. A degraded gasket can allow combustion gases to escape at the electrode port. Replacing both components together as part of routine maintenance or a service call ensures the burner control system operates as intended and helps prevent repeat service calls.
