Troubleshooting Tips and Instructions
When troubleshooting a Triangle Tube Prestige boiler, a methodical approach is essential․ Here are some tips and instructions to help you identify and resolve common issues⁚
- Check for Power⁚ Begin by verifying the presence of 120 volts at terminals L and N of the 120V terminal strip․ If there is no power, check the external power supply, external fuse or breaker․ If the internal fuse F1 is blown, replace it․
- Control Module Display⁚ The control module display provides valuable information about the boiler’s status; If the display is blank, check the wiring connections and the internal fuse F1․ If the display shows a number of 1 to 8 for the first digit followed by 2 or 3 digits (boiler temperature), the boiler is in normal operating mode․
- Check for Lockouts⁚ The boiler may enter a lockout mode for safety reasons․ A Soft Lockout will display a code, while a Hard Lockout will display an “E” followed by an error code․ Consult the “Soft Lockout Error Code” and “Hard Lockout Error Code” sections of this guide for specific troubleshooting instructions․
- Inspect the Combustion System⁚ Ensure the burner is operating correctly․ Check for proper gas pressure, airflow, and flame ignition․ Verify that the flue is clear and free of obstructions․
- Verify the Blower⁚ The blower is responsible for providing air to the burner; Ensure the blower motor is working and that the blower assembly is not blocked․ If the control module detects blower operation when it should not be, inspect the wiring harness and blower assembly․
- Check the Aquastat⁚ The aquastat controls the water temperature․ If the aquastat is malfunctioning, it can cause the boiler to overheat or fail to reach the desired temperature․ Inspect the aquastat and wiring, and ensure it is secure and in good condition․
- Inspect the DHW Sensor⁚ The DHW sensor measures the temperature of the domestic hot water․ Verify that the DHW sensor is properly connected and functioning correctly․ Ensure the DHW operating signal selection is set correctly․
- Purging the System⁚ Ensure the boiler and heating system have been properly purged and there is no entrapped air․ Inspect and verify heating system piping and its components․ Ensure piping is per the recommendations given in the Prestige Installation Manual or per other approved/recognized designed configurations․
Remember, always disconnect the power supply to the boiler before servicing and never bypass any boiler controls or devices except for momentary testing during troubleshooting․

Soft Lockout Error Code
A soft lockout error code on a Triangle Tube Prestige boiler indicates a minor issue that prevents the boiler from starting or continuing operation․ The boiler will remain in a shutdown mode until the condition is corrected․ Unlike a hard lockout, which requires a manual reset, a soft lockout will automatically reset after a specific time period, typically 150 seconds, allowing the boiler to restart․ The control module displays a soft lockout error code as a “b” followed by a two-digit number․ Here’s a breakdown of common soft lockout error codes and their possible causes⁚
- b-116⁚ This code indicates a low voltage issue․ The control module requires an incoming voltage of 120V and a frequency of 60Hz․ Check the voltage supply and wiring to the control module․ Ensure proper connections and replace any damaged wiring․
- b-119⁚ This code signals a problem with the LWCO (Low Water Cut-Off) device․ The LWCO device is responsible for shutting down the boiler if the water level falls below a safe level․ Inspect the LWCO device for proper operation and ensure it’s securely installed․ Check the wiring to the LWCO for any damage or loose connections․
- b-29⁚ This code indicates a blower malfunction․ The blower assembly is crucial for air circulation within the boiler․ Inspect the blower assembly for any obstructions, damage, or signs of wear․ Check the wiring to the blower for proper connections and replace any damaged wires․
For any soft lockout error code, it’s important to carefully examine the boiler’s operation and the relevant components․ Refer to the Prestige Boiler Installation and Maintenance Manual for detailed troubleshooting procedures and specific instructions for each error code․ If you are unable to resolve the issue, contact a qualified service technician for assistance․
Hard Lockout Error Code
A hard lockout error code on a Triangle Tube Prestige boiler indicates a serious issue that compromises the boiler’s safe operation․ The boiler will shut down completely and remain in a lockout state until the problem is addressed and the control module is manually reset․ A hard lockout is displayed on the control module as an “E” followed by a two-digit error code․ Here’s a guide to common hard lockout error codes and their potential causes⁚
- E-02⁚ This code signals a failed ignition attempt․ The boiler is unable to ignite the burner properly․ Check for a clear gas supply to the boiler, ensuring the gas valve is open and the gas pressure is sufficient․ Inspect the ignition system, including the electrodes and the igniter, for any damage or blockage․ Ensure the proper type of gas is being used, and verify that the gas regulator is correctly sized for the boiler․
- E-06⁚ This code indicates an internal failure within the control module․ The control module is responsible for managing the boiler’s operation and detecting errors․ If the control module is faulty, it can trigger a hard lockout․ Try resetting the control module and retrying the ignition sequence․ If the problem persists, contact Triangle Tube Technical Support for further assistance․
- E-07⁚ This code points to an internal failure within the control module, similar to E-06․ Reset the control module and attempt to restart the boiler․ If the error code reappears, contact Triangle Tube Technical Support for guidance․
- E-15⁚ This code indicates a problem with the IDWH (Indirect Domestic Hot Water) sensor․ The IDWH sensor monitors the temperature of the hot water in the indirect tank․ Inspect the IDWH sensor for damage or loose connections․ Ensure the sensor is properly installed and the wiring is secure․ If the sensor is faulty, replace it using Triangle Tube’s PSRKIT22, IDWH Sensor Kit․ Reset the control module and test the boiler’s operation․
Addressing hard lockout error codes requires careful troubleshooting and potentially professional intervention․ Consult the Prestige Boiler Installation and Maintenance Manual for detailed instructions specific to each error code․ If you’re unable to resolve the issue, contact a qualified service technician to diagnose and repair the problem․
