The Fenwal 35-63J101-011 Ignition Control Board replaces the following Johnson Ignition Controls.

G770KGA-1, G770KGA-2, G770KGA-3, G770KHA-2

APPLICATIONS

The Fenwal 35-63J series Intermittent Pilot Ignition Control (35-
63J) is a microprocessor based ignition control suitable for
replacing many existing intermittent pilot ignition controls from
various manufacturers.

The 35-63J is a direct form, fit, and functional replacement for
the discontinued Johnson G77x Series controls. The 35-63J is
available in a number of timing configurations that match popular
G77x applications. This provides a much better solution than a universal
type aftermarket control.

The 35-63J is suitable for many types of heating applications
including commercial cooking, furnaces and boilers. It is also great for water
heaters that require intermittent pilot ignition, burner supervision
through flame rectification, and safety shutoff. It can be used with
with Natural, LP, and the mixed gases that are used in
gas-fired appliances.

The microprocessor circuit design of the 35-63J provides precise,
repeatable timing and operating sequences. High-energy
spark output and excellent flame sense characteristics provide
reliable burner operation. The on-board diagnostics with LED
output make troubleshooting easy and ensure safe and efficient
operation.


FEATURES
- Safe start and full-time flame sensing
- Wide variety of prepurge and interpurge timings
- Single or three trials for ignition
- Diagnostic LED with Fenwal error codes
- Three ground terminals for ease of wiring
- Remote or local flame sense options
- Automatic 5 min or 1 hour reset after lockout options.
