NOTE: Shaded parts in Fig. 39, 40, 41, 42, and 43 are considered to be termination. These components should NOT be counted when determining pipe diameter. Roof termination is preferred since it is less susceptible to damage, has reduced chances to take in contaminants, and has less visible vent vapors.
b. Termination kit should be positioned where vent vapors will not damage plants/shrubs or air conditioning equipment. c. Termination kit should be positioned so it will not be affected by wind eddy (such as inside building comers) or that may allow recirculation of flue gases, airborne leaves, or light snow.
An external trap is not required when connecting the field drain to this condensate trap. The field drain connection (condensate trap or drain tube coupling) is sized for l/2-in. CPVC, 1/2-in. PVC, or 5/8-in. ID tube connection. Drain pipe and fittings must conform to ANSI standards and ASTM D1785, D2466 or D2846.

1. Fold heat tape in half and wrap on itself 3 times. 2. Locate heat tape between sides of condensate trap back. (See Fig. 50.) 3. Use wire ties to secure heat tape in place. Wire ties can be positioned in notches of condensate trap sides. (See Fig. 50.
PROCEDURE 1—SELF-TEST MODE The control center goes through a brief self-test whenever 115-v or 24-v power is interrupted. The self-test takes approximately 2 sec to complete. After power is restored, red (microprocessor) LED briefly comes on. Then green LED comes on for 1 sec, followed by 1 sec where both yellow and green LEDs are on.
2. Blower on —The blower motor is turned on IMMEDIATELY and slowly increases to maximum speed as soon as a call for heat is received. No blower calibration occurs. 3. Electronic Air Cleaner —The EAC-1 terminal does not operate in emergency heat mode.
8. Electronic Air Cleaner —The EAC-1 terminal is energized whenever blower operates. 9. Inducer speed operation —If cycle starts in low heat, inducer speed reduces slightly after the flame sense. If cycle starts in high heat, inducer speed increases 15 sec after flame sense.
1. Leave 115-v power to furnace turned on. 2. Remove main furnace door. 3. Remove blower access panel. 4. Move setup switch SW-6 to ON position. 5. Manually close blower access panel door switch. Use a piece of tape to hold switch closed. WARNING: Blower access panel door switch opens 115-v power to control center.
The DEHUM output on the thermidistat control or the humidistat output, is connected directly to the DEHUM terminal on the furnace control. In addition, the DE jumper located next to the DEHUM terminal must be removed to enable the DEHUM input (See Fig.
NOTE: The CF switches are factory set to provide continuous fan airflow equal to low-heat mode. 5. Replace main furnace door and blower access panel. C. Setup Switches (SW) The control center has 8 setup switches that may be set to meet the application requirements.
2. Locate setup switches on control center. (See Fig. 31.) 3. See Table 11 for setup switch description. (See Fig. 30.) 4. Replace main furnace door and blower access panel. NOTE: If a bypass humidifier is used, setup switch SW-3 (BPH) should be in ON position.
Furnace input rate must be within ±2 percent of input on furnace rating plate. 1. Determine natural gas orifice size and manifold pressure for correct input. a. Obtain yearly heat value average (at installed altitude) from local gas supplier. b. Obtain yearly specific gravity average from local gas supplier.
NOTE: DO NOT set low-heat manifold pressure less than 1.3-in. wc or more than 1.7-in. wc for natural gas. If manifold pressure is outside this range, change main burner orifices. CAUTION: DO NOT bottom out gas valve regulator adjusting screw. This can result in unregulated manifold pressure and result in excess overfire and heat exchanger failures.
j. Remove jumpers R to W/W1 and R to W2. 3. Verify natural gas input rate by clocking gas meter. NOTE: Be sure all pressure tubing, combustion-air and vent pipes, and burner enclosure front are in place when checking input by clocking gas meter. a. Calculate high-altitude adjustment (if required).
CANADA At installation altitudes from 2000 to 4500 ft, this furnace must be derated 5 percent by an authorized Gas Conversion Station or Dealer. To determine correct input rate for altitude, see example above and use 0.95 as derate multiplier factor. b.
m. Move setup switch SW-2 to OFF position and jumper R and W2 thermostat connections. (See Fig. 31.) This keeps furnace locked in high-heat operation. Repeat items h through k for high-heat operation. EXAMPLE: (High-heat operation at 0-2000 ft altitude) Furnace input from rating plate is 100,000 Btuh.
Furnace must operate within the temperature rise ranges specified on the furnace rating plate. Determine the air temperature as follows: 1. Place thermometers in return and supply ducts as close to furnace as possible. Be sure thermometers do not ’see’ heat exchangers so that radiant heat does not affect thermometer readings.
2. See thermostat manufacturer’s instructions for adjusting the heat anticipator and for varying heating cycle length. NOTE: When using an electronic thermostat, set cycle rate for 3 cycles per hr. 3. Return setup switch SW-2 to OFF position and replace thermostat on subbase.
3. Turn on 115-v power to furnace. 4. Set thermostat to call for heat. When pressure switches are functioning properly, fault code 42 will flash on control center approximately 10 sec after thermostat switch is closed. If either a fault code 31 or 32 is flashed when ICM inducer motor is disconnected, the furnace will shut itself down immediately.
