Operator: Save these instructions for future use!
If in doubt about whether your wiring is millivolt, line, or
low voltage, have it inspected by a qualified heating and
air conditioning contractor, electrician, or someone famil-
iar with basic electricity and wiring.
Do not exceed the specification ratings.
All wiring must conform to local and national electrical
codes and ordinances.
PRECAUTIONS
This control is a precision instrument, and should be
handled carefully. Rough handling or distorting compo-
nents could cause the control to malfunction.
To prevent electrical shock and/or equipment dam-
age, disconnect electric power to system, at main
fuse or circuit breaker box, until installation is
complete.
Do not short out terminals on gas valve or primary
control to test. Short or incorrect wiring will burn
out heat anticipator and could cause personal
injury and/or property damage.
