Triton Service Manual SVC1020T ; Rev 4 80 and 100 gallon chassis Safety Functions of the Controls Flame Detection Proof of flame is accomplished by flame rectification via a burner sensor electrode and earth ground. The presence of a flame is measured via a flame rod that points into the flame.
(27 attempts at ignition) and post purge. Condensate Removal Tube with Exhaust Tee Assembly An important part of the Triton is the condensate removal tube that comes included in the exhaust T. During main burner, water vapor is created. As the heat is transferred into the water thru the flue bundles, this water vapor condenses and becomes a liquid.

Page 32
Triton Service Manual SVC1020T ; Rev 4 80 and 100 gallon chassis Troubleshooting Error Codes Error A001 Ignition Lockout (continued) Gas Valve Checking Procedure • Cycle power and/or clear any alarms on the display. • Locate the large black wiring harness plugged into the top of the gas valve.
Triton Service Manual SVC1020T ; Rev 4 80 and 100 gallon chassis Troubleshooting Error Codes Error A002 Flame is Not Stable This alarm code means the unit had flame rectification within one heating cycle; but lost the flame rectification signal three times within one call for heat. Causes of this issue are: Incorrect gas pressure or gas supply issues, incorrect vent terminations, restricted exhaust vent, dirty flame rod.
Triton Service Manual SVC1020T ; Rev 4 80 and 100 gallon chassis Troubleshooting Error Codes Error A004 PoF Open During Heating The Proof of Fan pressure switch is open during heating. You can clear this error code by pressing clear button on the current alarm screen.

Gas Pressure Checking Procedures Gas Pressure Checking Procedure The Triton water heaters use a negative pressure gas valve so we do not check the manifold gas pressure. Our only checks are to confirm the inlet gas pressure is within minimum and maximum limits and verify the inlet pressure does not have more than a 1.5”w.c.
2.Locate the adjusting screw on the gas valve. (See pics below for reference) 3. Turn the Triton ON and demand heat. 4. If the unit does not go to main burner, turn unit OFF; turn the screw counterclockwise a 1/8 turn and restart the unit.
Triton Disassembly and Repair On the next few pages we have included instructions for replacing most repair parts on the Triton water heater. To further aid in the repair process we have also created some repair videos that can be accessed through the hyperlinks below.
Triton Service Manual SVC1020T ; Rev 4 80 and 100 gallon chassis Disassembly and Repair Ignition Control Board 1. Disconnect power to the water heater. 2. Remove all Molex connections to the control board. Wires are colored and the board locations have numbers to reconnect.

It is important to understand that Rheem in no way supports BACnet itself. We are only able to provide direction within our product to the location for data input. For example, if a a BACnet Facilitator called needing to input their configurations, we would be asked to direct him or her to the location in our menu to enter their configurations.
Page 56
Triton Service Manual SVC1020T ; Rev 4 80 and 100 gallon chassis BACnet Configurations • To access the menu containing BACnet configurations, the caller will select the “settings” icon in the bottom left of their display screen as pictured below.

The BACnet Facilitator will have the BACnet MAC Address. This does not come from us. If the caller is an end user, he/she will need to contact a BACnet Facilitator. The Baud Rate should only in very rare circumstances be adjusted. Rheem support does NOT under any circumstances provide advice for this setting.
