Honeywell VR8345 Installation Instructions Manual

VR8245 and VR8345 Universal
Electronic Ignition Gas Controls
APPLICATION
The universal electronic ignition gas controls are used in
gas-fired appliances with capacities up to 300 cu ft/hour
at 1 inch wc pressure drop [8.5 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.
Size (Inlet x Outlet)
