Post-Purge Timer:

This furnace is equipped with a post-purge timer located in the blower compartment on the control panel. It is pre-set at the factory for a 4 minute post-purge. This is designed to ensure that no residual heat or combustion odors permeate back into the home. The 4 minutes has been deemed sufficient, however if you experience the need for a longer post-purge, the device has 3 selectable settings; 4 minutes, 5 minutes and 7 minutes. By simply turning the knob to one of the remaining selections the post-purge time will be effected.

Electronic Air Cleaner (EAC) and Humidifier Installation:

The fan timer on this unit has designated terminals to control the operation of an electronic air cleaner and/or humidifier. These terminals provide line voltage for the control of these accessories, refer to Figure 8 on the next page. Connection between EAC and N6 provides a switched 115 vac to power an electronic fan cleaner. The same-switched 115 vac is available between Fan and N7 and may be used in conjunction with a humidistat to control a humidifier. These terminals are energized whenever the blower is active.
