Induced-Combustion Gas-Fired Furnaces
Application Data
Installation Guidelines Procedures
INTRODUCTION
The desire to conserve energy has created
greater use of insulation, improved vapor barriers,
weather stripping, etc. Homes are now tighter, resulting
in less natural air infiltration and inefficient furnace oper­
ation. The condition is further affected by the growing use
of kitchen and bathroom exhausts and even fireplaces.
Field studies indicate that combustion air starvation,
particularly in closet installations, points to a need for
positive furnace air supply, plus new guidelines for to­
day’s furnace applications.
A WARNING
These instructions cover minimum combustion air
requirements and venting practices. They also reflect
current conditions found in the field, and conform to
existing national standards, and safety codes. In
some instances, these instructions exceed certain
local codes and ordinances, especially those that may
not have kept pace with changing construction
practices. Carrier requires these standard pro­
cedures as a minimum for safe installation.

INSPECTION
Check available power supply to be sure it meets speci­
fications on wiring diagram and all motors in furnace.
Check available gas supply to see that it conforms to
gas specifications on AGA rating plate.
A CAUTION
Do not block openings in front of furnace or on
furnace top along side vent pipe. These openings pro­
vide air for combustion and ventilation. Never store
anything on or in contact with furnace, such as:
aerosol cans, rags, brooms and mops, cleaning tools
and aids, powders, bleaches, waxes, plastic items,
gasoline, kerosene, lighter fluids, cleaning fluids,
thinners, painting compounds or paper products.
Installation Procedures — These recommendations
apply to the installation and operation of gas furnaces
and piping systems for natural or LP (propane) gases.
Use these procedures in conjunction with your specific
furnace installation instructions.
Refer also to your gas supplier regulations and local
building, heating, plumbing and other codes for your
installation area.

FURNACE LOCATION —
COMBUSTION/VENTILATION AIR
Locate furnace close to chimney and as near to the
center of the air distribution system as possible. Install
furnace as level as possible. Provide ample space for
servicing and cleaning. Always comply with minimum
fire protection clearances shown on unit rating plate. Do
not install directly on carpeting, tile or any combustible
material other than wood flooring. Accessory eom-
bustible floor base is available from your dealer when
required.
The relief-air supply for the draft safeguard duct (draft
hood) must be in the same atmospheric pressure zone as
the combustion-air inlet supply to the furnace.
When a furnace is installed so that the supply ducts
carry air to areas outside the space containing the
furnace, the return air must also be handled by duct(s)
sealed to the furnace casing and terminating outside the
furnace location area.
All fuel-burning furnaces must be supplied with air
that enters the combustion process and then is vented to
the outdoors. Sufficient air must enter the space contain­
ing the furnace to replace the amount drawn up the vent
stack. Replacement air must be provided by means of
ducts from the outside to the furnace area or heated
spaee. Under all eonditions, enough air must be provided
to ensure there will be no negative pressure condition
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
