Carrier continues to lead the industry
with our new WeatherMaker® 8000
Two-Speed Induced-Combustion Gas
Furnace. Our furnace operates at 2
different speeds which provide
outstanding home comfort. This
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.
These 2-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 engineers have incorporated the
patented S-shaped 4-pass heat
exchanger, a soft mount 2-speed
inducer assembly, and a 2-stage slowopening gas valve to minimize sound
level. The Super-S heat exchanger
provides better heat transfer while
enabling us to make a compact furnace,
providing 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
Form 58TMA-8PD
EAC-1
PARK
3-amp fuse that protects the transformer
and control. Our control is backed by a
3-year Limited Warranty.
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, blower
speed selector, cased or uncased
cooling coils, low-voltage, humidifier,
and electronic air cleaner terminal
connections are among other features.
This furnace is designed for
multipoised downflow, right horizontal,
or left horizontal applications.

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. 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 component-test
feature to determine if a major
component has failed. The control will
check itself; then the low and high
inducer; silicon carbide ignition; low-,
medium-, and high-speed blower.
Another benefit of the control is the
PR1
your home heating requirements.
This furnace 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, wraparound construction. There are no spot
welds on the exterior surfaces of the
furnace. There is also double protection
for the cabinet. First, a galvanized steel
substrate provides resistance to rusting.
Then the cabinet is constructed of
prepainted steel—the same high-quality
finish found on refrigerators and
dishwashers.
Perhaps the most advanced feature of
the Carrier WeatherMaker 8000 Two-

Available in programmable and nonprogrammable models, Carrier thermostats
maintain a constant, comfortable temperature
level in the home.
For the ultimate in home comfort, Carrier’s 2, 4
and 8-zone systems allow temperature control
of individual “zones” of the home. This is accomplished through a series of electronic dampers
and remote room sensors. The 4-zone system
is shown.

By adding moisture to winter-dry
air, a Carrier humidifier can often
improve comfort and keep
furniture, rugs, and draperies in
better condition. Moisturizing
household air also helps to retain
normal body heat and provides
comfort at lower temperatures.
