Safety Considerations; Clearances To Combustibles; Electrostatic Discharge (Esd) Precautions - Bryant D Series Installation, Start-Up, And Operating Instructions Manual

This forced air furnace is equipped for use with natural gas at altitudes 0 - 10,000 ft (0 - 3,050m), except 140 size Furnaces are only approved for altitudes
0 - 7,000 ft. (0 - 2,135m).
An accessory kit, supplied by the manufacturer, shall be used to convert to propane gas use or may be required for some natural gas applications.
This furnace is for indoor installation in a building constructed on site. This furnace may be installed in a manufactured (mobile) home when stated on rating
plate and using factory authorized kit.
This furnace may be installed on combustible flooring in alcove or closet at minimum clearance from combustible material.
This appliance requires a special venting system. Refer to the installation instructions for parts list and method of installation. This furnace is for use with
schedule-40 PVC, PVC-DWV, CPVC or ABS-DWV pipe, and must not be vented in common with other gas-fired appliances. Construction through which
vent/air intake pipes may be installed is maximum 24 inches (600 mm), minimum 3/4 inches (19 mm) thickness (including roofing materials).
Furnace must be installed level, or pitched forward within 1/2 inch
of level for proper drainage. Failure will result in equipment or
property damage. See Installation Manual for IMPORTANT unit
support details on horizontal applications

SAFETY CONSIDERATIONS

Installing and servicing heating equipment can be hazardous due to
gas and electrical components. Only trained and qualified person-
nel should install, repair, or service heating equipment. Untrained
personnel can perform basic maintenance functions such as clean-
ing and replacing air filters. All other operations must be per-
formed by trained service personnel. When working on heating
equipment, observe precautions in literature, on tags, and on labels
attached to or shipped with unit and other safety precautions that
may apply.
Follow all safety codes. In the United States, follow all safety
codes including the National Fuel Gas Code (NFGC) NFPA
54-1999/ANSI Z223.1-1999 and the Installation Standards, Warm
Air Heating and Air Conditioning Systems (NFPA 90B)
ANSI/NFPA 90B. In Canada, refer to the current edition of the
CAN/CGA-B149.1- and .2-M95 National Standard of Canada,
Natural Gas and Propane Installation Codes (NSCNGPIC). Wear
safety glasses and work gloves. Have a fire extinguisher available
during start-up and adjustment procedures and service calls.
Recognize safety information. This is the safety-alert symbol
When you see this symbol on unit or in instructions and manuals,
be alert to potential for personal injury.
Understand the signal words DANGER, WARNING, and CAU-
TION. These words are used with the safety-alert symbol. DAN-

CAUTION: Electrostatic discharge can affect electronic
components. Take precautions during furnace installation
and servicing to protect the furnace electronic control.
Precautions will prevent electrostatic discharges from
personnel and hand tools which are held during the
procedure. These precautions will help to avoid exposing
the control to electrostatic discharge by putting the
furnace, the control, and the person at the same electro-
static potential.
