Kelly O'Brien, service operations manager of Guardian Environmental Services, Livonia, Mich., repaired Schultz's 20-year-old boiler. The boiler, located in the basement of her 100-year-old home, needed work partly because of years of neglect.
As part of the service call, O'Brien replaced the thermocouple, cleaned the burner section, and adjusted the manifold gas pressure. He partially drained the boiler, checked the pressure relief and fill pressure, and checked the boiler limit switch.
