These continuous pilot gas controls are used in gas-fired
appliances with capacities up to 200 cu ft/hour at 1 in. wc
pressure drop [5.7 cu m/hour at 0.25 kPa] on natural gas.
They include a manual valve, safety shutoff, single auto-
matic operators, and a pressure regulator. See Table 3 for
temperature ranges and regulator types.
