4.14 GAS VALVE ACTUATOR REPLACEMENT

If you need to replace the gas valve actuator, see TID-0092 for Actuator Replacement Kit P/N
27086-TAB. If you are replacing a newer actuator (P/N 124138), the wiring is unchanged.
However, complete the instructions below only if you are replacing an older actuator (P/N
69171, shown in Figure 4-15 below) to change the wiring to accept the new actuator.
Changing The Wiring From Old To New Gas Valve Actuator Instructions
1. Remove the new actuator cover, punch out the holes in the plastic to accommodate the
wiring, then insert the wires through wire conduit and wire it as follows:
•
Wire Terminals 4, 5, N, N, L and L identically to the old actuator.
•
Remove & dispose of the two wires attached to Terminals 1 and 2 and wire nut, and the
wire connecting Terminal 3 to the Low Gas Pressure Switch (three dashed lines).
Remove and Discard Both
Terminals 1, 2 & 3
appear only on older
actuator P/N 69171

2. Disconnect Wire 153 (dotted line) from Terminal 3 and connect it to the Low Gas Pressure
Switch.
