Start- -Up, Adjustment, And Safety Check; General - Carrier 140/E Series Installation, Start-Up, Operating And Service And Maintenance Instructions

1. For common vent, vent connector sizing and vent material: United States- -- -use the NFGC Canada- -- -use the CAN/CSA- -B149.1- -05
2. Immediately increase to 5- -in. (102 mm) or 6- -in. (152 mm) vent connector outside furnace casing when 5- -in. (127 mm) vent connect-
or is required, refer to Note 1 above.
3. Side outlet vent for upflow and downflow installations must use Type B vent immediately after exiting the furnace, except when
KGAVG0101DFG, Downflow Vent Guard Kit, is used in the downflow position.
4. Type- -B vent where required, refer to Note 1 above.
5. A 4- -in.(102 mm) single- -wall (26 ga. min.) vent must be used inside furnace casing and when the KGAVG0101DFG Downflow Vent
Guard Kit is used external to the furnace.
6. Accessory Downflow Vent Guard Kit, KGAVG0101DFG required in downflow installations with lower vent configuration.
7. Chimney Adapter Kit may be required for exterior masonry chimney applications. Refer to Chimney Adapter Kit, KGACA02014FC
or KGACA02015FC, for sizing and complete application details.
8. Secure vent connector to furnace elbow with (2) corrosion- -resistant sheet metal screws, spaced approximately 180_ apart.
9. Secure all other single wall vent connector joints with (3) corrosion resistant screws spaced approximately 120_ apart. Secure Type- -B
vent connectors per vent connector manufacturer's recommendations.
10. The total height of the vent and connector shall be at least seven feet for the 154,000 Btuh gas input rate model when installed in a
downflow application with furnace elbow turned to left side with the connector elbow outside furnace casing pointing upward. (See
Fig. 39.)
The horizontal portion of the venting system shall slope upwards
not less than 1/4- -in. per linear ft. (21 mm/m) from the furnace to
the vent and shall be rigidly supported every 5 ft. (1.5 M) or less
with metal hangers or straps to ensure there is no movement after
installation.
Sidewall Venting
This furnace is not approved for direct sidewall horizontal
venting.
In the U.S.: Per section 12.4.3.1 of the NFPA 54/ANSI
Z223.1- -2006, any listed mechanical venter may be used, when
approved by the authority having jurisdiction.
In Canada: Per section 8.24.2 of the CAN/CSA- -B149.1- -05,
any listed mechanical venter may be used, when approved by the
authority having jurisdiction.
Select the listed mechanical venter to match the Btuh input of the
furnace being vented. Follow all manufacturer's installation
requirements for venting and termination included with the listed
mechanical venter.

General

WARNING
!
FIRE HAZARD
Failure to follow this warning could result in personal injury,
death or property damage.
This furnace is equipped with manual reset limit switches in
the gas control area. The switches open and shut off power to
the gas valve, if a flame rollout or overheating condition
occurs in the gas control area. DO NOT bypass the switches.
Correct problem before resetting the switches.
Venting Notes for Fig. 37- -49
1. Maintain 115- -v wiring and ground. Improper polarity will
result in rapid flashing LED and no furnace operation.
2. Make thermostat wire connections at the 24- -v terminal
block on the furnace control. Failure to make proper con-
nections will result in improper operation. (See Fig. 26.)
3. Gas supply pressure to the furnace must be greater than
4.5- -in. wc (0.16 psig ) but not exceed 14- -in. wc (0.5
psig).
4. Check all manual- -reset switches for continuity.
5. Replace blower compartment door. Door must be in place
to operate furnace.
6. Setup switch descriptions The variable speed furnace con-
trol has DIP switches to select thermostat staging, blower
off delay timings, air flow selection and other operational
or service related functions. (See Fig. 27, 59 and Table 8.)
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care
and wear appropriate protective clothing, safety glasses and
gloves when handling parts, and servicing furnaces.
