PILOT GAS CONNECTION

Install fitting into pilot gas outlet (see fig. 2), turning until finger-tight. Insert clean, deburred tubing all the way through the fitting. While holding the tubing securely, slowly tighten fitting until you feel a slight "give". Tighten the fitting an additional 1 1⁄2 turns.

ENERGY CUT OFF (E.C.O.)

CONNECTION

A five-function valve uses the 2 E.C.O. terminals that are connected to the magnetic assembly where the thermo- couple connects to the 36C valve line interrupter. An E.C.O. device is mounted in the furnace near the limit control and a lead assembly is connected to the E.C.O. terminals on the 36C valve.

INSTALLATION (cont’d)

THERMOCOUPLE CONNECTION

The thermocouple connection should be clean to ensure good electrical contact.

Run the thermocouple nut into the power unit tapping as far as possible by hand. Then use a small wrench to set the nut with a 1⁄4 to 1⁄2 additional turn. Do not overtighten.

Connect leads from E.C.O. terminals to E.C.O. device on furnace. Test E.C.O. device for continuity. If there is no continuity, power unit will not hold in.

If the furnace does not have an E.C.O. device, use the jumper provided in the pack.

SYSTEM WIRING

!CAUTION

To prevent electrical shock and/or equipment damage, disconnect electrical power to system at main fuse or circuit breaker box until installation is complete.

NOTE

All wiring should be installed in accordance with local and national electrical codes and ordinances.

Always check that the electrical power supply used agrees with the voltage and frequency shown on the gas control.

The typical wiring diagram shows only the terminal iden- tification and wiring hook up. Always refer to wiring instructions provided by Equipment Manufacturer for sys- tem hookup operation.
