Rheem Triton Quick Start Guide
[Peel here to open]
A Successful Install STARTS HERE
Before starting, gather required additional tools: a multimeter, a manometer, and an optional combustion analyzer.
Key initial steps for a successful installation:
- Inspect Shipment: Check for any damage that may have occurred during shipping or handling.
- Prepare Thermal Expansion Tank: Ensure the thermal expansion tank is properly sized for the application and pressurized to the building static water pressure.
- Locate Exhaust Tee & Neutralizer: The exhaust tee and neutralizer are shipped with the water heater in a separate box and need to be connected for proper operation.
Step 1: Connect the Inlet and Outlet
Five water inlet and outlet connections are located at the top, side, and bottom for easy piping.
- Two 2" Water Connection Ports on Front
- Two 2" Water Connection Ports on Back
- One 1-1/2" Water Connection Port on Top
A diagram shows a Rheem Triton water heater. Connections are labeled: Gas Connection [?], Electric Connection [⚡], 3 Hot Water Connections [?], 2 Cold Water Connections [?], Air Intake [?], and Exhaust [?].
Step 2: Connect the Gas Line
For best performance:
- Ensure that all gas connections, regulator(s), and meter are sized properly for the BTU/h rating (See Installation Manual for charts).
- Regulator should be a minimum of 8 feet from the water heater.
- If installing more than one water heater, make sure each water heater has a regulator.
- Check all connections and fittings for leaks.

Step 3: Hook Up the Intake and Exhaust
For optimum performance, proper venting is essential. Here are a few tips for installation:
- Calculate total equivalent feet.
- 90° and 45° elbows reduce the equivalent vent length by the specified values.
- Ensure that vent runs are sloped (1/4" per foot rise recommended).
- Install condensate drain / loop for air intake.
- Rheem recommends long sweep elbows when possible.
Diagrams show different venting components and configurations:
- Elbow Types & Equivalents:
- Short Sweep 90° Elbow: 10' Straight Equivalent
- Standard Sweep 90° Elbow: 8' Straight Equivalent
- Long Radius Sweep 90° Elbow: 5' Straight Equivalent
- Standard 45° Elbow: 2.5' Straight Equivalent
Venting Configurations:
- Direct Vent Vertical Vent Horizontal Intake
- Direct Vent Horizontal Vent Vertical Intake

- Remember that the condensate trap is part of the exhaust tee and does not require extra plumbing.
- Recommended minimum 3" vertical drop for every 4 ft. of horizontal run.
- Plumb the condensate line for the proper size and run to avoid air bubbles, which can prevent drainage.
Step 4: Connect the Electrical
To ensure proper ignition:
- Ensure all electrical connections are secure.
- Use correct polarity.
- Connect to a 120VAC – 50/60 Hz power supply.
- Ensure water heater is properly grounded back to the main breaker box with minimum 12 gauge wire.
- Ensure breaker is sized properly for 7 AMP service per water heater.
A diagram shows the electrical connection points on the water heater, including a switch connection.
- Connect the yellow wires from the water heater to the exhaust pressure switch.
- Connect the white wires from the heater to the flue temperature sensor.
Step 5: Complete the Setup
Once power is applied to the water heater and the ‘On’ button is pressed, the LCD will automatically begin the Startup Wizard:
- Set the Time and Date.
- Schedule Hours of Operation for the business – Enables Triton to save energy and money when the business is not operating.
- Connect to WiFi – Enables users to receive leak and diagnostic alerts, usage reports and more.
Follow the on-screen instructions to complete setup.
