(ITS AND ABRASION HAZARD
Failure to %11ow this caution may result in personal ir!iury.
Sheet metal parts may have sharp edges or burrs Use care and
wear appropriate protective clothing and gloves when han-
dling parts Failure to follow this caution could result in
personal injury
FURNACE RELIABILITY HAZARD
Improper installation or misapplication of _hrnace can require
excessive servicing or cause premature component failure
Application of this l\maace should be indoors with special
attention gi\en to xent sizing and material, gas input rate, air
temperature rise, unit leveling, and unit sizing
FIRE, EXPLOSION, ELECTRICAL SHOCK AND
(ARBON MONOXIDE POISONING HAZARD
Failure to follow this wariaing could result in electrical shock,
firQ personal injury, or death.
Improper installation, adjustment, alteration, service, mainte-
nancQ or use can cause carbon monoxide poisoning, explo-
sion, tire, electrical shock, or other conditions which may
cause personal ir!iu V or property damage. Consult a qualified
installer, sela-ice agency, local gas supplier, or your distribu-
tor or branch ibr information or assistance. The qualified
installer or agency must use only [i_ctory-authorized and
listed kits or accessories when modi_)ing this prodact.
Installing and servicing heating equipment can be hazardous due to
gas and electrical components. Only trained and qualified
personnel should ilistaH, repair, or service heating equipment.
Untrained personnel can perform basic maintenance _hnctions
such as cleaning and replacing air filters. All other operations must
be performed by trained service personnel. When working on
heating equipment, observe precautions in literature, on tags, and
or* labels attached to or shipped with unit and other safety
precautions that may apply.
These instructions cover the n?inin?um requirements and conform
to existing national standards and sa_kty codes. In some instances,
these instl_actions exceed certain local codes and ordinances,
especially those that may not have kept up with changing residen-
tial constl_./ction practices. We require these instl_./ctions as a
minimum %r a safe installation.
Wear safety glasses and work gloves Have a fire extinguisher
axailable during start-up and adjustment procedures and serxice
calls.
Recognize safety information. This is the safbty-alert symbol .A_
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 injm2¢ or death. WARNING signifies
hazards which could result in personal injury or death. CAUTION
is used to identii) unsaI:_ 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.
The 58MVP Multipoise Condensing Gas-Fired Furnaces are
C.S.A. (formerly AGA and CGA) design=certified %r natural and
propane gases (see I\N'nace rating plate) and for installation in
alcoves, attics, basements, closets, utility rooms, crawlspaces, and
garages. The furnace is factory-shipped [br use with natmal gas. A
C.S.A. (formerly AGA and CGA) listed gas conversion kit is
required to convert f_arnace %r use with propane gas.
See Fig. 3 for required clearances to combustibles.
Maintain a l-in. clearance fiom combustible materials to supply air
ductwork for a distance of 36 inches horizontally from the ftmaace.
See NFPA 90B or local code _br t:urther requirements.
These furnaces SHALL NOT be installed directly on carpeting,
tile, or any other combustible material other than wood flooring. In
downflow installations, factory accesso_' floor base MUST be
used when installed on combustible materials and wood flooring.
Special base is not required when this Nriaace is installed on
manufacturer's (:oil Assembly Part No. CD5 or CK5, or when (Toil
Box Part No. KCAKC is used. These fi/rnaces are suitable for
installation in a structure built on site or a manu£_ctured 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, manufactured (mobile) homes or outdoors.
This Nmace 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 fl_ese
remm air limits may affect reliability of heat exchangers, motors
and controls. (See Fig. 4.)
These Nmaces are shipped with the drain and pressure robes
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.
This Nrnace must be installed with a direct-vent (combustion air
and flue) system and a fi_ctory accessory termination kit. In a
direct-vent system, all air for combustion is taken directly fiom the
outside atmosphere and all flue products are discharged to tl_e
outside atmosphere. See fi/rnace and factoQ" accessory termination
kit instructions for proper installation.
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 instrtlctions.
Always install furnace to operate within the furnace's intended
temperature-rise range with a duct system which has an external
static press-are within the allowable range as specified in the SET
TEMPERATURE RISE section of these insm/ctions.
When a /:umace is installed so that the supply ducts cat_" air
circulated by the _imaace to areas omside the space containing tl_e
Nmace, the return air must also be handled by a duct(s) sealed to
the furnace casing and terminating outside the space containing the
i:t_rnace.

[NIT DAMAGE HAZARD
Failure to follow this caution may result in damage to unit
components.
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 t]'om personnel and hand tools
which are held during the procedure. These precautions will
help to avoid exposing the control to electlostatic discharge
by putting the t:umacQ the control, and the person at the same
electrostatic potential.
1. Disconnect all power to the furnace. Multiple disconnects may
be required. DO NOT TOU(H THE CONTROL OR ANY
WIRE CONNE(TED TO THE ( ONTROL PRIOR TO DIS-
CHARGING YOUR BODY'S ELECTROSTATI( CHARGE
TO GROUND,
2 Firefly 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 tong as you do nothing that
recharges your body with static electricity (fbr 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 f_/rnace again befbre touching
control or wires
5 Use this procedure for installed and uninstalled (ungrounded)
f_/rnaces

MINOR PROPERTY DAMAGE
Failure to fbllow this caution may result in minor property
damage.
Local codes may require a drain pan under entire furnace and
condensate trap when a condensing fhmace is used in an attic
application or over a finished ceiling.
NOTE: In (anada, installations shall be in accordance with
cun'ent NS(NGPIC andor local codes.
Step 2--Upflow Applications
An upflow furnace application is where furnace blower is located
below combustion and controls section of furnace, and conditioned
air is discharged upwards
CONDENSATE TRAP LOCATION (FACTORY-SHIPPED
ORIENTATK)N)
The condensate trap is factory installed in the blowm shelf and
factory connected for UPFLOW applications. A fi_ctow-supplied
robe is used to extend the condensate trap drain connection to the
desired furnace side for field drain attachment. See Condensate

The thrnace and its return air system shall be designed and
installed so that negative pressure created by the air circulating fan
cannot affect another appliance's combustion air supply or act to
mix products of confbustion with circulating air, and that the air
circulating fhn of the fhmace, if installed in an enclosure commu-
nicating with another fllel-burning appliance not of the direct-vent
type, shall be operable only when any door or panel covering an

--€ [;NIT DAMAGE HAZARD
This gas fire, ace may be used %r construction heat provided
that:
-The [hrnace is permanently installed with all electrical
wiring, piping, venting and ducting installed according to
these installation instructions A return air duct is provide&
sealed to the ft_raace casing, and terminated outside the space
containing the thrnace This prevents a negative pressure
condition as created by the circulating air blower, causing a
flame rollout an&or drawing combustion products into the
strncttlre.
-The furnace is controlled by a thermostat It may not be "hot
wired" to provide heat continuously to the stlt/cture without
thermostatic control.
-(Dan outside air is provided for combustion. This is to
minimize the con'osive efDcts of adhesives, sealers and other
constn_ction materials. It also prevents the entraimnent of
d_wall dust into combustion air_ which can cause fouling and
plugging of Nrnace components.
-The temperature of the return air to the /hrnace is no less
than 55°F_ with no evening setback or shutdown. The use of
the fimaace 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
construction process nmst be either changed or thoroughly
cleaned prior to occupancy.
-The Nrnace, ductwork and filters are cleaned as necessary to
remove &ywall dust and construction debris fiom all HVA(
system components after construction is completed.
