WARNING
!
EXPLOSION HAZARD!
NEVER USE AN OPEN FLAME TO DETECT GAS
LEAKS. EXPLOSIVE CONDITIONS MAY OCCUR.
USE A LEAK TEST SOLUTION OR OTHER AP-
PROVED METHODS FOR LEAK TESTING. FAILURE
TO FOLLOW THIS WARNING COULD RESULT IN
PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
▲
CAUTION
!
To prevent shortening its service life, the Furnace
should NOT be used as a "Construction Heater" during
the finishing phases of construction until the require-
ments listed in item 9, a-h of the safety section of this
publication have been met. Condensate in the pres-
ence of chlorides and fluorides from paint, varnish,
stains, adhesives, cleaning compounds, and cement
create a corrosive condition which may cause rapid
deterioration of the heat exchanger.
▲
WARNING
!
SAFETY HAZARD
DO NOT USE SEMI-RIGID METALLIC GAS CONNEC-
TORS (flexible GAS lines) within the Furnace cabinet.
Failure to follow this warning could result in property
damage, personal injury or death.
▲
CAUTION
!
Do NOT install the furnace in a corrosive or
contaminated atmosphere.
Failure to follow this caution could result in early
equipment failure.
NOTE: The furnace must be installed level. The only
allowable variation would be slightly to the left and/
or forward in upflow installations or slightly toward
the front in horizontal
necessary for proper condensate drainage.

WARNING
!
SAFETY HAZARD
DO NOT INSTALL THE FURNACE DIRECTLY ON CAR-
PETING, TILE OR OTHER COMBUSTIBLE MATERIAL
OTHER THAN WOOD FLOORING. FOR VERTICAL
DOWNFLOW APPLICATIONS, SUBBASE
(BAYBASE205) MUST BE USED BETWEEN THE FUR-
NACE AND COMBUSTIBLE FLOORING. WHEN THE
DOWNFLOW FURNACE IS INSTALLED VERTICALLY
WITH A CASED COIL, A SUBBASE IS NOT REQUIRED.
FAILURE TO FOLLOW THE WARNING EXACTLY COULD
RESULT IN SERIOUS PERSONAL INJURY, PROPERTY
DAMAGE OR DEATH.
The following safety practices and precautions must be
followed during the installation, servicing, and opera-
tion of this furnace.
1. Use only with the type of gas approved for this Fur-
nace. Refer to the furnace rating plate.
2. Install this furnace only in a location and position
as specified in "Location and Clearances" on page 6
of these instructions.

3. Provide adequate combustion and ventilation air to
the Furnace space as specified in "Air for Combus-
tion and Ventilation" of these instructions.
4. Combustion products must be discharged outdoors.
Connect this furnace to an approved vent system
only, as specified in the "Venting" section (pages 15-
27), of these instructions.
5. Never test for gas leaks with an open flame. Use a
commercially available soap solution made specifi-
cally for the detection of leaks to check all connec-
tions, as specified in the "Gas Piping" section start-
ing on page 34.
6. Always install the furnace to operate within the
furnace's intended temperature-rise range with a
duct system which has an external static pressure
within the allowable range, as specified on the unit
rating plate. Airflow with temperature rise for cfm
versus static is shown in the Service Facts accom-
panying this Furnace.
