Product Description
Robertshaw - 780-704 Convert "D" and "K" Series heat sensing/flame switch pilot ignition systems to "flame rectification" without replacing the existing gas valve. Use the cross-reference for the selection of the proper Modernization Kit. These modernization Kits are designed to replace the obsolete "D" and "K" Series Pilot Ignition Control Units. Included in each kit is a universal pilot mounting bracket with factory installed electrode and sensor, ignition control unit, wiring harness and complete-in-depth instructions.
NOTE: The 780-704/705 modernization kits DO NOT include a new gas valve. They are designed to utilize the existing gas valve. The existing gas valve is at least 12 years old or older. We suggest that a complete new 712 series kit with a new gas valve be considered before using the 780-704 or 780-705 modernization kit.
