Robertshaw 780-704

IGNITION CONTROL MODERNIZATION KIT

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.
