VR8300A Continuous Pilot Combination
Gas Control
APPLICATION
These continuous pilot gas controls are used in gas-fired
appliances with capacities up to 200 cfh at 1 in. wc
pressure drop (5.7 cmh at 0.25 kPa) on natural gas.
Included are a manual valve, safety shutoff, two automatic
operators, and a pressure regulator. See Table 2 for
temperature range and regulator type.
The VR8300 setup for natural gas includes a 39369 LP
Conversion Kit. The kit contains a new cap screw, a
pressure regulator adjustment screw, a tapered spring and
a conversion label. The control must be equipped with a
standard servo pressure regulator. Step-opening gas
controls cannot be converted.

inlet flange).
Adapters:
Adapters available for 1/2 and 3/4 in. straight and angle
connections. Refer to Table 3.
Electrical Ratings:
Voltage and Frequency: 24 Vac, 50/60 Hz.
Current Draw: 0.70A.
Capacity:
a
Capacity based on 1000 Btu/cu ft, 0.64 specific gravity natural gas at 1 in. wc pressure drop (37.3 MJ/cu m, 0.64 specific
