VR8245 and VR8345 Electronic Ignition
Gas Controls
APPLICATION
The electronic ignition gas controls are used in gas-fired
appliances with capacities up to 415 cu ft/hour at 1 inch
wc pressure drop [11.8 cu m/hour at 0.25 kPa] for
natural gas. These gas controls will operate with a direct
spark (DSI), hot surface (HSI) or intermittent pilot
ignition. The control includes a manual valve, two
automatic operators, a pressure regulator, pilot
adjustment, pilot plug, conduit cover and ignition
adapter. Refer to the following list for the specifications.
