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 No.
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 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 would 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.

ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS

Electrostatic discharge can affect electronic components.
Take precautions during furnace installation and servicing to
protect the furnace electronic control. Precautions will pre-
vent 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
electrostatic potential.
1. Disconnect all power to the furnace. DO NOT TOUCH THE
CONTROL OR ANY WIRE CONNECTED TO THE CON-
TROL PRIOR TO DISCHARGING YOUR BODY'S ELEC-
TROSTATIC CHARGE TO GROUND.
2. Firmly touch a clean, unpainted, metal surface of the furnace
chassis which is close to the control. Tools held in a person's
hand during grounding will be satisfactorily discharged.
3. After touching the chassis you may proceed to service the
control or connecting wires as long as you do nothing that
recharges your body with static electricity (for example; DO
NOT move or shuffle your feet, DO NOT touch ungrounded
objects, etc.).
4. If you touch ungrounded objects (recharge your body with
static electricity), firmly touch furnace again before touching
control or wires.
5. Use this procedure for installed and uninstalled (ungrounded)
furnaces.
6. Before removing a new control from its container, discharge
your body's electrostatic charge to ground to protect the
control from damage. If the control is to be installed in a
furnace, follow items 1 through 5 before bringing the control
or yourself into contact with the furnace. Put all used AND
new controls into containers before touching ungrounded
objects.
7. An ESD service kit (available from commercial sources) may
also be used to prevent ESD damage.
The 58MVP Multipoise Condensing Gas-Fired Furnaces are CSA
(A.G.A. and C.G.A.) certified for natural and propane gases and
for installation in alcoves, attics, basements, closets, utility rooms,
crawlspaces, and garages. The furnace is factory-shipped for use
with natural gas. A manufacturer's accessory gas conversion kit is
required to convert furnace for use with propane gas.
These furnaces SHALL NOT be installed directly on carpeting,
tile, or any other combustible material other than wood flooring. In
downflow installations, a manufacturers accessory floor base
MUST be used when installed on combustible materials and wood
flooring. Special base is not required when this furnace is installed
.
on manufacturer's Coil Assembly Part No. CD5 or CK5, or when
Coil Box Part No. KCAKC is used. The design of this furnace line
is not CSA (A.G.A. and C.G.A.) certified for installation in mobile
homes, recreation vehicles, or outdoors. These furnaces are suit-
able for installation in a residence built on site or a manufactured
residence completed at final site.
These furnaces are shipped with the drain and pressure tubes
connected for UPFLOW applications. Minor modifications are
required when used in DOWNFLOW, HORIZONTAL RIGHT, or
HORIZONTAL LEFT (supply-air discharge direction) applica-
tions as shown in Fig. 1. See details in Applications section.
These furnaces are shipped with the following materials to assist in
proper furnace installation. These materials are shipped in the main
blower compartment.
Installer Packet includes:
Installation, Start-Up, and Operating Instructions
Service and Maintenance Instructions
User's Information Manual
Warranty Certificate
Loose Parts Bag includes:
Pressure tube extension
Collector box or condensate trap extension tube
Inducer housing drain tube
1/2-in. CPVC street elbow
Drain tube coupling
Drain tube coupling grommet
Vent and combustion-air pipe support
Combustion-air pipe perforated disk assembly
Condensate trap hole filler plug
Vent and combustion-air intake hole filler plug
This furnace must be installed with a direct-vent (combustion air
and flue) system and a factory accessory termination kit. In a
direct-vent system, all air for combustion is taken directly from the
outside atmosphere and all flue products are discharged to the
outside atmosphere. See furnace and factory accessory termination
kit instructions for proper installation.
Before installing the furnace in the United States, refer to the
current edition of the NFGC and the NFPA 90B. For copies of the
NFGC and NFPA 90B, contact the National Fire Protetion
