Continuous Pilot
Combination Gas Control
Application
These continuous pilot gas controls are used in gas-fired
appliances with capacities up to 300 feet
3
/hour at one inch wc
pressure drop [5.7 meters
3
/hour at 0.25 kPa] on natural gas.
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.
BODY PATTERN: Straight-through body pattern.
INLET X OUTLET SIZES AVAILABLE: 1/2 by 3/4 inch
and 3/4 by 3/4 inch.
ADAPTERS: Adapters available for 1/2 and 3/4 inch straight
and angle connections. Refer to Table 2.
ELECTRICAL RATINGS:
Voltage and Frequency: 120 Vac, 60 Hz.
Current Draw: 0.14A.
