Product Data
A11263
The 59TP5A Two--stage Multipoise Performance™Boost
Condensing Gas Furnace features two--stage heating comfort along
with SEER--boosting year--round electrical efficiency. The
Comfort Heat TechnologyRtwo--stage gas valve is at the heart of
the comfort provided by this furnace, along with the
electrically--efficient basic ECM blower motor, and two--speed
inducer motor. With an Annual Fuel Utilization Efficiency (AFUE)
of up to 96.7%, this Performance™Series two--stage gas furnace
provides exceptional savings when compared to a standard furnace.
This gas furnace also features 4--way multipoise installation
flexibility, and is available in five model sizes. The 59TP5A can be
vented for direct vent/two--pipe, ventilated combustion air, or
single--pipe applications. All units meet California Air Quality
Management District emission requirements. All sizes are design
certified in Canada.

Venting System Length Calculations
The maximum length for each vent pipe (inlet or exhaust) equals the Maximum Equivalent Vent Length (MEVL) from Table 1 or Table 3
minus the number of elbows multiplied by the deduction for each elbow in Table 2.
Standard vent terminations and concentric vent terminations count for zero deductions.
Example
A direct--vent 60,000 Btuh furnace installed at 2100 ft. (640 M ) with 2--in. (51 mm) vent piping. Venting system includes, FOR EACH
PIPE, (3) 90_long radius elbows, (2) 45_long radius elbows and a concentric vent kit.
Maximum Equivalent Vent Length =127 ft. (From Table 1)
Deduct (3) 90 long radius 3 x 3 ft. =- 9 ft. (From Table 2)
Deduct (2) 45 long radius 2 x 1.5 ft. =- 3 ft. (From Table 2)
Maximum Vent Length =115 ft. For EACH vent or inlet pipe

*Not all families have these models.
Notes:
1. 3 --- and 4 --- in. Vent pipe systems require long radius elbows.
2. Total equivalent vent lengths under 10’ for 40,000 require the use of an outlet choke plate at altitude 0 to 2,000 ft (0 to 610M).
Failure to use an outlet choke when required may result in flame disturbance or flame sense lockout.
3. Vent sizing for Canadian installations over 4500 ft (1370m) above sea level are subject to acceptance by the local authorities having jurisdiction.
4. NA --- Not allowed; pressure switch will not close, or flame disturbance may result.
5. Do not use pipe size greater than those specified in table or incomplete combustion, flame disturbance, or flame sense lockout may occur.
6. Size both the combustion ---air and vent pipe independently, then use the larger diameter for both pipes.
7. Assume the two 45_elbows equal one 90_elbow. Wide radius elbows are desirable and may be required in some cases.
8. Elbows and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count.
9. The minimum pipe length is 5 ft. (1.5 M) for all applications.
10. Use 3 ---in. (76 mm) diameter vent termination kit for installations requiring 4 ---in. (102 mm) diameter pipe.

RETURN AIR TEMPERATURE
This furnace is designed for continuous return--air minimum temperature of 60_F(15_C) db or intermittent operation down to 55_F(13_C)
db such as when used with a night setback thermometer. Return--air temperature must not exceed 80_F(27_C) db. Failure to follow these
return air limits may affect reliability of heat exchangers, motors and controls.

Concentric Vent Kit
A93086
A concentric vent kit allows vent and combustion--air pipes to
terminate through a single exit in a roof or side wall. One pipe
runs inside the other allowing venting through the inner pipe and
combustion air to be drawn in through the outer pipe.

Downflow Subbase
A88202
One base fits all furnace sizes. The base is designed to be installed
between the furnace and a combustible floor when no coil box is
used or when a coil box other than a Carrier cased coil is used. It is
CSA design certified for use with Carrier branded furnaces when
installed in downflow applications.
