Gas Boiler Repair: ECO Series 2 Controls
If you smell gas or a CO alarm sounds, leave the home and call the gas utility or 911 from outside.
For gas hot-water boiler repair, contact an independent heating contractor and distinguish the boiler from a steam system. The Weil-McLain ECO Series 2 manual describes hydronic control inputs and lockout records. Provide the boiler model, series, CP record and displayed fault before discussing a sensor, control or circulation repair.

ECO fault records guide a hydronic service call
Preserve the fault display and identify the installed series. The ECO low-water instructions distinguish actual system condition from the control input and its wiring. Give the contractor the symptom and available records; opening hot piping or defeating a protective input is not a homeowner observation.
According to Weil-McLain ECO Series 2 boiler manual:
Check for low water condition in system.
