Jandy® Pool/Spa Heater Igniter Replacement Kit | R0016400

Check the application

Jandy lists R0016400 for Hi-E2 350 heaters in the cited manufacturer parts list.

This listing is for the 350 application shown in the source; do not substitute it for a different heater capacity. Match the rating-plate model, serial number, fuel and installed configuration before ordering. A shared Hi-E2 name does not establish interchangeability with other heater families or every revision.

Part details

The Rev T manual lists this individual service part. The 2026 catalog instead lists R0457503 as an igniter assembly and gasket replacing R0016400 and R0205300; confirm the supplied package before ordering.

Service guidance

Heater installation and service require a qualified pool-heater professional. Follow the exact unit instructions, isolate power and gas before service, and never bypass a safety control.
