INSTALLATION (cont’d)
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.
SYSTEM WIRING
To prevent electrical shock and/or equipment dam-
age, disconnect electrical power to system at main
fuse or circuit breaker box until installation is
complete.
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.
