Two-Speed Heating for
Energy-Efficient Gas
Furnaces
Carrier leads the industry with our
newWeatherMaker®8000Two-Speed
Induced-Draft Gas Furnace. This
furnace can operate at 2 different speed
settings which provide outstanding
home comfort. The WeatherMaker
8000 furnace is built with the most
advanced manufacturing equipment,
processes, and technology available in
order to ensure top quality. Packed into
the cabinet are the industry’s foremost
dealer and homeowner features. The
58TUA Upflow Furnace is a great asset
to Carrier’s list of product leadership in
the gas furnace industry.
These2-speed induced-combustion,
gas-fired furnaces offer not only low
installation costs, but fuel economy as
well—delivering an Annual Fuel
Utilization Efficiency (AFUE) rating
of 80.0 percent. The Carrier
WeatherMaker 8000 Two-Speed
utilizes a hot surface, silicon carbide
ignition system to save energy and
increase reliability.
Our design uses the patented
S-shaped 4-pass heat exchanger, a soft
mount 2-speed inducer assembly, and a
2-stage slow-opening gas valve to
minimizesoundlevel. TheSuper-Sheat
exchanger provides better heat transfer
while enabling us to make a compact
furnace. This provides more room in
closet, utility room, and short basement
installations. The heat exchanger is
constructed of aluminized steel and is
backed by a 20-year Limited Warranty.
The Carrier WeatherMaker 8000
Two-Speed Gas Furnace will meet your

2
homeheatingrequirements.Thisfurnace
family provides the widest range of
heating capacities available.
The superior attention to cabinet
detail is obvious. The Carrier
WeatherMaker 8000 Two-Speed
features 1-piece, seamless, wrap-
around construction. There are no spot
welds on the exterior surfaces of the
WeatherMaker 8000 Two-Speed
Furnace.Thereisalsodoubleprotection
for the cabinet. First, a galvanized steel
substrate provides resistance to rusting.
Then the cabinet is constructed of
prepaintedsteel—thesamehigh-quality
finish found on refrigerators and
dishwashers.
Perhaps the most advanced feature
oftheWeatherMaker8000Two-Speed
is the state-of-the-art microprocessor
control center which shows true
leadership in furnace technology.
The simplified electronics in this
control provide high reliability while
performing many of the functions of
older, electro-mechanical devices in
other furnaces. Advanced features of
the control show Carrier’s true
leadership in furnace technology.
The control provides blower delay at
start-up and shutdown, while
monitoring furnace operations and
functions. In the unlikely event of a
service call, in less than a minute, the
technician can use the self-test feature
to determine if a major component has
failed. The control will check itself,
then the low and high inducers, silicon
carbide ignition, and low-, medium-,
and high-speed blower. The control
also features a 3-amp fuse that protects
the transformer and control.
Ourinduced-combustion furnace has
a patented draft safeguard switch. The
draft safeguard switch will stop furnace
operation if the vent system becomes
blocked or is not operating properly.
Best of all, the Carrier
WeatherMaker 8000 two-speed is
easily installed. Many features make
this furnace the easy choice for
replacement or new construction
markets. Left and right connections
are provided for gas and electrical
supplies. An easy-to-remove bottom,
heating and cooling blower speed
selector, cased or uncased cooling
coils, low-voltage humidifier, and
electronic air cleaner terminal
connections are among other features.

1. Two additional 7⁄8-in. dia holes are located in the top plate.
2. Minimum return-air openings at furnace, based on metal duct. If flex duct is used,
see flex duct manufacturer's recommendations for equivalent diameters.
3. Minimum return-air opening at furnace:
a. For 800 CFM–16-in. round or 141⁄2x 12-in. rectangle.
b. For 1200 CFM–20-in. round or 141⁄2x 191⁄2-in. rectangle.
c. For 1600 CFM–22-in. round or 141⁄2x 231⁄4-in. rectangle.
d. For airflow requirements above 1800 CFM, see Air Delivery table in Product Data literature for specific
use of single side inlets. The use of both side inlets, a combination of 1 side and the bottom, or the
bottom only will ensure adequate return air openings for airflow requirements above 1800 CFM.
