Fig. 13ÐTypical Gas Pipe Arrangement

Canadian installations, all electrical connections must be made in accordance with Canadian Electrical Code CSA C22.1, or authori- ties having jurisdiction.

NOTE: Proper polarity must be maintained for 115-v wiring. If polarity is incorrect, control status code indicator light will flash rapidly and furnace will not operate.

The cabinet MUST have an uninterrupted or unbroken ground according to NEC ANSI/NFPA 70-1999 and Canadian Elec- trical Code CSA C22.1 or local codes to minimize personal injury if an electrical fault should occur. This may consist of electrical wire or conduit approved for electrical ground when installed in accordance with existing electrical codes. Do not use gas piping as an electrical ground. Failure to follow this warning could result in electrical shock, fire, or death.

24-V WIRING

Make field 24-v connections at the 24-v terminal strip. (See Fig. 14.) Connect terminal Y as shown in Fig. 15 for proper operation in cooling mode. Use AWG No. 18 color-coded wire only.

The 24-v circuit contains an automotive-type, 3-amp fuse located on the main control board. Any direct shorts during installation, service, or maintenance could cause this fuse to blow. If fuse replacement is required, use ONLY a 3-amp fuse of identical size.

ACCESSORIES

1.Electronic Air Cleaner (EAC)

Two spring clamp terminals (for 12 gage maximum, solid or stranded wire), marked EAC-1 and EAC-2, are provided for EAC connection. (See Fig. 14.) These terminals are energized with 115v (1.5-amp maximum) during blower motor opera- tion. To connect EAC power leads to furnace control board, strip approximately 1/8 in. of insulation from wire. Open terminal by depressing switch arm with a screwdriver or finger, and insert wire as shown in Fig. 16.

2.Humidifier (HUM)

Screw terminals (HUM and COM-24V) are provided for 24-v humidifier connection. The terminals are energized with 24v (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 11ÐVenting

→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- structions (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.
