EZ-Link Cable Connector 72 in

The Rheem RTG20040 EZ-Link Cable Connector joins two compatible Rheem tankless water heaters so they operate as a single unit. It is intended for installers or homeowners expanding hot-water capacity by linking a pair of supported heaters.

Includes EZ Link Cable

The kit supplies the dedicated EZ Link cable that carries the communication signals between the two heaters. No additional wiring or separate controller is provided, so the cable alone enables the paired-heater function.

Check heater compatibility before ordering

Verify that both heaters carry model prefixes RTG or RTGH, as the connector is designed only for those Rheem tankless series. The accessory does not fit other brands or Rheem series outside the stated prefixes.

Questions about this item

How often should the 72 in EZ-Link cable be inspected or replaced?

Inspect the cable and connectors during routine tankless heater maintenance; replace if the plastic jacket shows cracking, the pins are corroded, or the locking tabs no longer latch securely.

What is the first limitation when two heaters run continuously linked by this cable?

The cable itself does not limit output; the combined flow and temperature rise are constrained by each heater's own burner capacity and gas supply.

Does the connector add heat or electrical draw during all-day operation?

The passive plastic connector draws no power and generates no measurable heat; only the linked heaters consume gas and electricity.
