* Permissible limits of the voltage range at which the unit operates satisfactorily.
† Time-delay type is recommended.
‡ Length shown is as measured 1 way along wire path between unit and service panel for maximum 2 percent voltage drop.
2. Humidifier (HUM)
Quick-connect terminal (HUM) and screw terminal (C
24V) are provided for 24-v humidifier connection. The termi-
nals are energized with 24-v 0.5-amp maximum after inducer
motor prepurge period.
DO NOT connect furnace control HUM terminal to HUM
(humidifier) terminal on Thermidistat™, Zone Controller or
similar device. See Thermidistat, Zone Controller, thermostat,
or controller manufacturer's instructions for proper connec-
tion. A failure to follow this warning could result in fire.
NOTE: A field-supplied, 115-v controlled relay connected to
EAC terminals may be added if humidifier operation is desired
during blower operation.

Step 9—Venting
Refer to the national or local installation code such as NFGC in the
-
United States or the NSCNGPIC in Canada for proper vent sizing
and installation requirements. Use the enclosed Installation In-
struction (Single-Stage Vent Tables for Category I Fan-Assisted
Furnaces) for a quick, easy reference.
After fully assembling the vent connector to the furnace flue collar,
securely fasten the vent connector to the collar with two field-
supplied, corrosion-resistant, sheet metal screws located 180° apart
and midway up the collar.
The horizontal portion of the venting system shall maintain a
minimum of 1/4-in. upward slope per linear ft and it shall be
rigidly supported every 5 ft or less with hangers or straps to ensure
that there will be no movement after installation.
