MULTIPLE FURNACES IN COMMON DUCT WORK
Multiple furnaces connected to common duct work, either supply, return, or both supply and return
must be wired so that all furnace blower motors are energized at the same time.
Failure to turn all blowers on at the same time can cause a reversal of air flow in those
units where the blower motor is not operating. This reversal of air flow can cause premature blower,
blower motor, wiring and or heat exchanger failure.
Please consult the factory for specific wiring instructions for your application.
