These continuous pilot gas controls are used in gas-fired
appliances with capacities up to 300 feet
pressure drop [5.7 meters
They include a manual valve, safety shutoff, two automatic
operators, a pressure regulator, pilot adjustment, and a con-
duit cover. See Table 1 for temperature ranges and regulator
types.
