Codes And Standards - Carrier Series 100 Installation, Start-Up, And Operating Instructions Manual

Combustion products must be discharged outdoors. Connect this
furnace to an approved vent system only, as specified in the
Combustion Air and Vent piping sections of these instructions.
Never test for gas leaks with an open flame. Use a commercially
available soap solution made specifically for detection of leaks to
check all connections as specified in the GAS PIPING section of
these instructions.
Always install the furnace to operate within the furnace's intended
rise range with a duct system which has an external static pressure
within the allowable range as specified in the SET TEMPERA-
TURE RISE section of these instructions. See furnace rating plate.
When a furnace is installed so that supply ducts carry air circulated
by the furnace to areas outside the space containing the furnace,
the return air shall also be handled by ducts sealed to the furnace
casing and terminating outside the space containing the furnace.
A gas-fired furnace for installation in a residential garage must be
installed as specified in the Hazardous Locations section of these
instructions.
→
The furnace may be used for construction heat provided that the
furnace installation and operation complies with the first CAU-
TION in the LOCATION section of these instructions.
→
This gas furnace may be used for construction heat provided that:
• The furnace is permanently installed with all electrical wiring,
piping, air filters, venting and ducting installed according to
these installation instructions. A return air duct is provided,
sealed to the furnace casing, and terminated outside the space
containing the furnace. This prevents a negative pressure
condition as created by the circulating air blower, causing a
flame rollout and/or drawing combustion products into the
structure.
• The furnace is controlled by a thermostat. It may not be "hot
wired" to provide heat continuously to the structure without
thermostatic control.
• Clean outside air is provided for combustion. This is to
minimize the corrosive effects of adhesives, sealers and other
construction materials. It also prevents the entrainment of
drywall dust into combustion air, which can cause fouling and
plugging of furnace components.
• The temperature of the return air to the furnace is maintained
between 55°F (13°C) and 80°F (27°C), with no evening setback
or shutdown. The use of the furnace while the structure is under
construction is deemed to be intermittent operation per our
installation instructions.
• The air temperature rise is within the rated rise range on the
furnace rating plate, and the firing rate has been set to the
nameplate value.
• The filters used to clean the circulating air during the construc-
tion process must be either changed or thoroughly cleaned prior
to occupancy.
• The furnace, ductwork and filters are cleaned as necessary to
remove drywall dust and construction debris from all HVAC
system components after construction is completed.
• After construction is complete, verify furnace operating condi-
tions including ignition, input rate, temperature rise and vent-
ing, according to the manufacturer's instructions.
→
The furnace shall be installed so that the electrical components are
protected by water.
These furnaces are shipped with the following materials to assist in
proper furnace installation. These materials are shipped in the main
blower compartment.

When this furnace is installed with a direct vent (combustion-air
and vent) system, a factory accessory termination kit MUST be
used. In a direct-vent system, all air for combustion is taken
directly from the outdoor atmosphere and flue gases are discharged
to the outside atmosphere. See furnace and factory accessory
vent-air intake termination kit instructions for proper installation.
For accessory installation details, refer to accessory installation
instructions.

CODES AND STANDARDS

Follow all national and local codes and standards in addition to
these instructions. The installation must comply with regulations
of the serving gas supplier, local building, heating, plumbing, and
other codes. In absence of local codes, the installation must
comply with the national codes listed below and all authorities
having jurisdiction.
In the United States and Canada, follow all codes and standards for
the following:
Step 1—Safety
• US: National Fuel Gas Code (NFGC) NFPA 54-2002/ANSI
Z223.1-2002 and the Installation Standards, Warm Air Heating
and Air Conditioning Systems ANSI/NFPA 90B
→
• CANADA: National Standard of Canada, Natural Gas and
Propane Installation Code (NSCNGPIC) CSA B149.1-05
Step 2—General Installation
• US: NFGC and the NFPA 90B. For copies, contact the National
Fire Protection Association Inc., Batterymarch Park, Quincy,
MA 02269; or for only the NFGC contact the American Gas
Association, 400 N. Capitol, N.W., Washington DC 20001
• A manufactured (Mobile) home installation must conform with
the Manufactured Home Construction and Safety Standard,
Title 24 CFR, Part 3280, or when this standard is not
applicable, the Standard for Manufactured Home Installation
(Manufactured Home Sites, Communities, and Set-Ups),
