This control is a precision instrument, and should be handled carefully. Rough handling or distorting compo- nents could cause the control to malfunction.
!CAUTION
To prevent electrical shock and/or equipment damage, 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 pri- mary control to test. Short or incorrect wiring will burn out heat anticipator and could cause per- sonal injury and/or property damage.
