Carrier 58MVP Installation, Start-Up, And Operating Instructions Manual page 4

heating equipment, observe precautions in literature, on tags, and
on labels attached to or shipped with unit and other safety
precautions that may apply.
These instructions cover the minimum requirements 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 up with changing residen-
tial construction practices. We require these instructions as a
minimum for a safe installation.
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 the unit and in instructions or
manuals, be alert to the potential for personal injury.
Understand these signal words: DANGER, WARNING, CAU-
TION, and NOTE. These words are used with the safety-alert
symbol. DANGER identifies the most serious hazards which will
result in severe personal injury or death. WARNING signifies
hazards which could result in personal injury or death. CAUTION
is used to identify unsafe practices which may result in minor
personal injury or product and property damage. NOTE is used to
highlight suggestions which will result in enhanced installation,
reliability, or operation.
CUTS HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and
wear appropriate protective clothing and gloves when han-
dling parts.
The 58MVP Condensing Gas-Fired Furnaces are C.S.A. (formerly
AGA and CGA) design-certified for natural and propane gases
(see furnace rating plate) and for installation in alcoves, attics,
basements, closets, utility rooms, crawlspaces, and garages. The
furnace is factory-shipped for use with natural gas. A C.S.A.
(formerly AGA and CGA) listed gas conversion kit is required to
convert furnace for use with propane gas.
See Fig. 3 for required clearances to combustibles.
Maintain a 1-in. clearance from combustible materials to supply air
ductwork for a distance of 36 inches horizontally from the furnace.
See NFPA 90B or local code for further requirements.
These furnaces SHALL NOT be installed directly on carpeting,
tile, or any other combustible material other than wood flooring.
These furnaces are suitable for installation in a structure built on
site or a manufactured building completed at final site. The design
of this furnace line is NOT C.S.A. (formerly AGA and CGA)
design-certified for installation in recreation vehicles, manufac-
tured (mobile) homes or outdoors.
This furnace is designed for continuous return-air minimum
temperature of 60°F db or intermittent operation down to 55°F db
such as when used with a night setback thermostat. Return-air
temperature must not exceed 85°F db. Failure to follow these
return air limits may affect reliability of heat exchangers, motors
and controls. (See Fig. 4.)
These furnaces are shipped with the drain and pressure tubes
connected for UPFLOW applications. Minor modifications are
required when used in HORIZONTAL RIGHT, or HORIZONTAL
LEFT (supply-air discharge direction) applications as shown in
Fig. 1. See details in Applications section.
.
Fig. 4—Return-Air Temperature
Never test for gas leaks with an open flame. Use a commercially
available soap solution made specifically for the detection of leaks
to check all connections as specified in the GAS PIPING section
of these instructions.
Always install 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 in the SET
TEMPERATURE RISE section of these instructions.
CARBON MONOXIDE POISONING HAZARD
Failure to properly seal duct could result in death and/or
personal injury.
Do NOT draw return air from inside a closet or utility room
where furnace is located. Return air duct MUST be sealed to
furnace casing.
A gas-fired furnace for installation in a residential garage must be
installed as specified in the Hazardous Locations section.
The furnace is not to be used for temporary heating of buildings or
structures under construction unless the furnace installation and
operation complies with first CAUTION in the LOCATION
section of these instructions.
These furnaces are shipped with the following materials to assist in
proper furnace installation. These materials are shipped in the main
blower compartment.
