CHECK SAFETY CONTROL CIRCUIT, after burner adjustments are made, for satisfactory
operation.
1. Pilot: With main burner operating, turn the pilot gas adjusting screw clockwise
until pilot gas is turned off. See figures 14, 15, & 16 on pages 14 & 15. Within 90 seconds
the main gas control should close, shutting off the gas to the main burner.
2. High limit control (figure 22 on page 19). Remove cover and note temperature setting.
Decrease this setting to minimum and operate boiler. When the boiler water temperature
exceeds the control temperature setting, the control will open the circuit, closing the
automatic main gas valve.
