Arrived on site for a reported boiler leak and an unresponsive upstairs thermostat. Upon inspection, the source of the leak was identified as the boiler vent piping. The existing venting was removed and replaced with new Z-Vent piping from the boiler discharge to the vertical connection in the garage. All vent connections were properly sealed, and correct pitch was verified throughout. At this time, no leaks are present. Further troubleshooting revealed the thermostat wiring between the relay board and the upstairs thermostat had no continuity. The thermostat wire was traced and found to be spliced to another wire. The splice was repaired, restoring proper continuity between the relay board and the upstairs thermostat. During testing, a delay was observed between the thermostat opening and closing the call for heat. This was discussed with Ziggy, and he was advised to monitor the thermostat for any additional signs of failure. The system is currently operating properly.
