VR8300/VR8301
Continuous Pilot Combination
Gas Control
Application
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.
BODY PATTERN: Straight-through body pattern.
INLET X OUTLET SIZES AVAILABLE: 1/2 x 1/2 in., 1/2 x
3/4 in., and 3/4 x 3/4 in. (factory-installed inlet flange).
ADAPTERS: Adapters available for 1/2 and 3/4 inch straight
and angle connections. Refer to Table 4.
ELECTRICAL RATINGS:
Voltage and Frequency: 24 Vac, 50/60 Hz.
Current Draw: 0.70A.
CAPACITY: See Table 1.
