3. For normal installations, use moisture-resistant No. 14
wire suitable for at least 167°F (75°C) if using a flame
safeguard primary control, or for at least 194°F (90°C) if
using a flame safeguard programming control.
4. For high temperature installation, use moisture-resistant
No. 14 wire selected for a temperature rating above the
maximum operating temperature.
5. Check the power supply circuit. The voltage and
frequency must match those of the valve.
6. Refer to Fig. 5 or 6 for typical field wiring connections.
Follow the burner manufacturers wiring diagram if
provided.
7. Make wiring connections inside the actuator housing
(Fig. 7):
a. Loosen the cover screw in the front of the actuator
housing, and remove the housing cover.
b. If a conduit is required, run the conduit through the
opening in the actuator housing, and run the
external wires through the conduit.
c. Using solderless connectors, connect the external
wires to the two 6 in. (152.4 mm) black leadwires
(from the coil).
d. Locate the connections inside the actuator housing.
e. Replace the housing cover, and tighten the cover
screw holding it to the actuator housing.
8. Recheck the wiring circuits before putting the valve into
service.
