ACCESSORIES

1.Electronic Air Cleaner (EAC)

Connect an accessory Electronic Air Cleaner (if used) us- ing 1/4-in female quick connect terminals to the two male 1/4-in quick-connect terminals on the control board marked EAC-1 and EAC-2. The terminals are rated for 115VAC, 1.0 amps maximum and are energized during blower motor operation. (See Fig. 33.)

2.Humidifier (HUM)

Connect an accessory 24 VAC, 0.5 amp. maximum hu- midifier (if used) to the 1/4-in male quick-connect HUM terminal and COM-24V screw terminal on the control board thermostat strip. The HUM terminal is energized when gas valve relay (GVR) is energized. (See Fig. 33.)

NOTE: A field-supplied, 115-v controlled relay connected to EAC terminals may be added if humidifier operation is desired during blower operation.

NOTE: DO NOT connect furnace control HUM terminal to HUM (humidifier) terminal on Thermidistat, Zone Controller or similar device. See Thermidistatt, Zone Controller, thermostat, or controller manufacturer’s instructions for proper connection.

VENTING

The furnace shall be connected to a listed factory built chimney or vent or a clay-tile lined masonry or concrete chimney. Venting into an unlined masonry chimney or concrete chimney is prohibited. When an existing Category I furnace is removed or replaced, the original venting system may no longer be sized to properly vent the attached appliances. An improperly sized Category I venting system could cause the formation of condensate in the furnace and vent, leakage of condensate and combustion products, and spillage of combustion products into the living space.
