SERIES 35-63J
INSTALLATION INSTRUCTIONS FOR REPLACING JOHNSON CONTROLS G77X
AND OTHER MODELS WITH FENWAL SERIES 35-63J IP IGNITION CONTROL
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 popu-
lar G77x applications providing a better solution than a univer-
sal type aftermarket control. The most common applications are
listed in "Control Cross Reference" on page 2.
The 35-63J is suitable for many types of heating applications
including commercial cooking, furnaces, boilers, and water
heaters that require intermittent pilot ignition, burner supervi-
sion through flame rectification, and safety shutoff. It is
designed for use with Natural, LP, and mixed gases used in
gas-fired appliances.
The microprocessor circuit design of the 35-63J provides pre-
cise, 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.

ROLLOUT SWITCH Some control applications may have a separate rollout switch directly connected to the old ignition control. In this case, the Vent Damper rollout switch (normally closed) should be connected directly to the THS terminal on the 35-63J. Verify the rollout switch is wired in series (downstream) with the thermostat signal. -
