When operating control (A) calls for heat, it energizes main gas valves (B), starting burner operation.
The burners will operate until operating control (A) is satisfied. The high limit control (C), will stop burner
operation in case of excessive steam pressure (steam boiler) or excessive boiler water temperature (water boiler).
Low water cut-off (D) will stop burner operation if the water level in boiler drops below the lowest safe level.
The pilot safety switch (E), connected to main gas valve (B), prevents operation of the main burners in case the
pilot flame becomes extinguished. Pilot safety switch (E) provide for 100% shut-off of gas supply.
