VR8304M Intermittent Pilot
Combination Gas Control

APPLICATION

These intermittent pilot gas controls are used in gas-
fired appliances with capacities up to 300 feet
1 inch wc pressure drop [8.5 meters
on natural gas. They include a manual valve, two
automatic operators, pressure regulator, and a pilot
adjustment. See Table 1 for temperature range and
regulator type. The VR8304M setup for natural gas
includes a 393691 LP conversion kit. The kit contains a
new cap screw, pressure regulator adjustment screw, a
tapered spring, and a conversion label. The control must
be equipped with a standard servo pressure regulator.
