2. Firmly touch a clean, unpainted, metal surface of the furnace chassis which is close to the control. Tools held in a person’s hand during grounding will be satisfactorily discharged.
CAUTION: Application of this furnace should be in- doors with special attention given to vent sizing and material, gas input rate, air temperature rise, and unit sizing. Improper installation or misapplication of the furnace can require excessive servicing or cause prema- ture component failure.
I. LOCATION A. General CAUTION: DO NOT install furnace in a corrosive or contaminated atmosphere. Make sure all combustion and circulating air requirements are followed. DO NOT use this furnace during construction when adhesives, sealers, and/or new carpets are being installed and curing.
c. If furnace is installed to obtain return air is taken directly from hallway or space adjacent to furnace, all air for combustion must come from outdoors. 2. Air from outside the structure requires 1 of the following methods: a. If combustion air is taken from outdoors through 2 vertical ducts, the openings and ducts MUST have at least 1 sq in.
IV. FILTER ARRANGEMENT WARNING: Never operate unit without a filter or with filter access door removed. A failure to follow this warning could result in fire, personal injury, or death. The 2 factory-supplied filters are shipped in the blower compart- ment.
WARNING: Use the proper length of pipes to avoid stress on gas control manifold. A failure to follow this warning could result in a gas leak causing fire, explosion, personal injury, or death. CAUTION: Use a backup wrench at furnace gas control when connecting gas pipe to furnace to avoid damaging gas controls or manifold.
Install accessible manual shutoff valve upstream of furnace gas controls and within 72 in. of furnace. A 1/8-in. NPT plugged tapping is provided on gas value for test gage connection.
A terminal block (EAC-1 [hot] and EAC-2 [neutral]) is provided for EAC connection. (See Fig. 10.) The terminals are energized with 115v, 1-amp maximum during blower motor operation. 2. Humidifier (HUM) Screw terminals (HUM-1 and C OM ) are provided for 24-v humidifier connection.
The gas service pressure must not exceed 0.5 psig (14-in. wc), and be no less than 0.16 psig (4.5-in. wc). Thermostat wire connections at R and W/W1 are the minimum required for gas heating operation. W2 must be connected for 2-stage heating thermostats.

a. Inducer prepurge period—As inducer motor IDM comes up to low speed or high speed, the low-heat pressure switch contacts LPS (or LPS and HPS) close to begin a 15-sec prepurge period. b. Ignitor warm-up—At the end of prepurge period, hot surface ignitor HSI is energized for a 17-sec ignitor warm-up period.
(3.) When thermostat is satisfied, R to G-and-Y cir- cuits are opened. The outdoor unit stops, and furnace blower motor BLWM continues operating on high-cool speed for an additional 90 sec. b. Two-Speed Cooling Outdoor Unit (See Fig. 12 for thermostat connections.
b. When installed with a heat pump, furnace control CPU automatically holds blower off time to 22 sec during HSI ignitor on period. After 17 sec of HSI ignitor on period, a trial-for-ignition sequence occurs as described above for gas heating.
g. Turn high-heat adjusting screw (5/64 hex Allen wrench) counterclockwise (out) to decrease input rate or clock- wise (in) to increase rate. NOTE: DO NOT set high-heat manifold pressure less than 3.2-in. wc or more than 3.8-in. wc for natural gas. If manifold pressure is outside this range, change main burner orifices.

a. Place duct thermometers in return and supply ducts as near furnace as possible. Be sure thermometers do not see heat exchangers so that radiant heat will not affect thermometer readings.
17. The thermostat anticipator should NOT be in this circuit while measuring current. If thermostat has no subbase, thermostat MUST be disconnected from R and W/W1 wires during current measurement. Return SW-2 to final desired location after completing reading.
