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-BI49.1- 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 adjustraent procedures and service calls. Recognize safety information. This is the safety-alert symbolz_ x.

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 win 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

¥!_['ff:.llii[*l_'l

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 coturol, 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), FgraJy touch furnace again before touching control or wires.

5. Use this procedme 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.

LOCATION

Step 1---General

When a furnace is installed so that supply ducts carry air to areas outside the space containing the furnace, return air must also be

handled by ducts sealed to furnace casing. The ducts terminate outaide the space containing the furnace to ensure there will not be a negative pressure condition within equipment room or space.

Furnace may be located in a confined space without special provisions for dilution or ventilation air. This furnace must be

installed so electrical components are protected from water.

UPFLOW OR DOWNFLOW

NOTE: For proper furnace operation, install furnace so that it is level or pitched forward within 1/2 in. to ensure proper condensate drainage from secondary heat exchangers.

HORIZONTAL

A93025

MAX 857=

If these furnaces are used during construction when adhe- sives, sealers, and/or new carpets are being installed, make

sure all combustion and circulating air requirements are followed. If operation of furnace is required during construc-

tion, use clean outside air for combustion and ventilation. Compounds of chlorine and fluorine, when burned with

combustion air, form acids which will cause corrosion of heat exchangers. Some of these compounds ,are found in paneling,

dry wall adhesives, paints, thinners, masonry cleaning mate- rials, and many other solvents commonly used in the con-

struction process.

Excessive exposure to contaminated combustion air will result in safety and performance related problems.

Provide ample space for servicing and cleaning. Always comply with minimum fire protection clearances shown on unit's clear-

ance to combustibles label. (See Fig. 3.) Locate furnace where available electric power and gas supplies meet specifications on

furnace rating plate.

MIN 557=

A93042

NOTE: These furnaces are designed for a minimum continuous return-air temperature of 60°F or intermittent operation down to 55°F such as when used with a night setback thermostat. Return-air temporature must not exceed a maximum of 85°F. Failure to follow these return-air temperature limits may affect reliability of heat exchangers, motors, and controls.

Locate furnace as close to center of air distribution system as possible.

Locate furnace so combustion-air pipe lengths are not exceeded.

Refer to Table 6.

Step 2--Low-Fire Only Installation

This 58MVP furnace can be installed to operate in the low-fire only heating mode when sized using the low-fire heating capacity.

This is accomplished by placing setup switch SW-2 in the ON position to provide only low-fire-heat operation. See Fig. 25 and

Table 10. With this setup, high-fire operation will not occur.

When the model no. on the furnace rating plate is followed by an asterisk (*), the furnace has an alternate low-fire only efficiency

rating as listed in the GAMA and CEC directories. This alternate

rating will be listed as the furnace model number followed by an

(-L) suffix.

18-IN. MINIMUM

TO BURNERS

A93044

When furnace is installed in a residential garage, it must be installed so that burners and ignition sources are located a

minimum of 18 in. above floor. The furnace must be located or protected to avoid physical damage by vehicles. When

furnace is installed in a public garage, airplane hangar, or other building having a hazardous atmosphere, unit must be installed in accordance with requirements of National Fire

Protection Association, Inc.

¥__

The furnace can operate in the high-fire mode when certain fault conditions occur. The following precautions should be taken:

1. Size gas piping based on the high-fire input.

2. Check the high-fire input and adjust it per the main literature instructions.

NEVER assume the high-fire input rate is not important for low-fire-only installation.

Step 3--Furnace Location Relative to Cooling Equipment

The cooling coil must be installed parallel with or on downstream

side of furnace to avoid condensation in heat exchanger. When installed parallel with a furnace, dampers or other means used to

control flow of air must prevent chilled air from entering furnace. If dampers are manually operated, they must be equipped with a

means to prevent operation of either unit unless damper is in full-heat or full-cool position.

Step 4--Hazardous Locations

INSTALLATION

Step 1--Leveling Legs (If Desired)

When furnace is used in upflow position with side inlet(sL leveling legs may be desired. (See Fig. 12.) Install field-supplied,

corrosion-resistant 5/16-in. machine bolts and nuts.

5/16_

1¾"

A89014

Fig. 12--Leveling Legs

NOTE: The maximum length of bolt should not exceed 1-1/2 in.

1. Position furnace on its back. Locate and drill a 5/16 in. diameter hole in each bottom corner of furnace. (See Fig. 12.)

Holes in bottom closure panel may be used as guide locations.

2. For each hole, install nut on bolt and then install bolt and nut in hole. (Install flat washer if desired.)

3. Install another nut on other side of furnace base. (Install flat washer if desired.)

4. Adjust outside nut to provide desired height, and tighten inside

nut to secure arrangement.

NOTE: Bottom closure mttst be used when leveling legs are used.

See Bottom Closure Panel section.

Step 2--Installation in Upflow or Downflow Applications

NOTE: This furnace is approved for use on combustible flooring

when manufacturer's accessory floor base, Part No.

KGASB020 IALL, is used. Manufacturers accessory floor base in not required when this furnace is installed on manafacturer's Coil

Assembly Part No. CD5 or CK5, or Coil Box part No. KCAKC is used.

I. Determine application being installed from Table 1.

2. Construct hole in floor per dimensions specified in Table l and Fig. 13.

3. Construct plenum to dimensions specified in Table l and Fig.

13.

4. If downflow subbase (KGASB) is used, install as shown in Fig. 14.

If coil assembly CD5 or CK5 or Coil Box KCAKC is used, install as shown in Fig. 15.

NOTE: Remove furnace perforated, discharge duct flanges when they interfere with mating flanges on coil on downflow subbase.

To remove furnace perforated, discharge duct flange, use wide duct pliers or duct flange tool to bend flange back and forth until

it breaks off. Be careful of sharp edges. (See Fig. 16.)

Do not bend duct flanges inward as shown in Fig. 16. This will affect airflow across heat exchangers and may cause limit

cycling or premature heat exchanger failure. Remove duct flange completely or bend it inward a minimum of 210 ° as shown in Fig. 16.

Step 3--Installation in Horizontal Applications

These furnaces can be installed horizontally in either horizontal left or right discharge position. In a crawlspace, furnace can either be hung from floor joist or installed on suitable blocks or pad.

Furnace can be suspended from each corner by hanger bolts and angle iron supports. (See Fig. 17.) Cut hanger bolts (4 each 3/8-in.

all-thread rod) to desired length. Use l X 3/8-in. flat washers, 3/8-in. lockwashers, and 3/8-in. nuts on hanger rods as shown in

Fig. 17. Dimples are provided for hole locations. (See Fig. 2.)

The entire length of furnace MUST be supported when

furnace is used in a horizontal position to ensure proper draining. When suspended, bottom brace supports sides and

center blower shelf. When unit is supported from the ground, blocks or pad should support sides and center blower shelf

8J'ea.

AIR DUCTS

Step 1--General Requirements

The duct system should be designed and sized according to

accepted national standards such as those published by: Air

Conditioning Contractors Association (ACCAJ, Sheet Metal and Air Conditioning Contractors National Association (SMACNA) or

American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE). Or consult factory The Air Systems Design

Guidelines reference tables available from your local distributor. The duct system should be sized to handle the required system

design CFM at the design static pressure.

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 a duct(s) sealed to the furnace casing and terminating outside the space containing the furnace.

Secure ductwork with proper fasteners for type of ductwork used. Seal supply- and return-duct connections to furnace with code

approved tape or duct sealer. Flexible connections should be used between ductwork and furnace to prevent transmission of vibration. Ductwork passing

through unconditioned space should be insulated to enhance system performance. When air conditioning is used. a vapor

barrier is recommended. Maintain a I-in. clearance from combustible materials to supply air

ductwork for a distance of 36 in. horizontally from the furnace. See NFPA 90B or local code for further requirements.

Step 2--Ductwork Acoustical Treatment

Metal duct systems that do not have a 90 degree elbow and 10 fi of main duct to the first branch take-off may require internal

acoustical lining. As an alternative, fibrous ductwork may be used if constructed and installed in accordance with the latest edition of

SMACNA construction standard on fibrous glass ducts. Both acoustical hning and fibrous ductwork shall comply with NFPA 90B as tested by UL Standard 181 for Class 1 Rigid air ducts.

Step 3--Supply Air Connections

UPFLOW FURNACES Connect supply air duct to 3/4-ni. flange on furnace supply-air

outlet. The supply-air duct attachment must ONLY be connected to furnace supply-/outlet-air duct flanges or air conditioning coil casing (when used). DO NOT cut main furnace casing to attach supply side air duct, humidifier, or other accessories. All accesso-

ries MUST be connected external to furnace main casing.

DOWNFLOW FURNACES Connect supply-air duct to supply-air opening on furnace. The

supply-air duct attachment must ONLY be connected to furnace supply/outiet or air conditioning coil casing (when used), when

installed on non-combustible material. When installed on combus- tible material, supply-air duct attachment must ONLY be con-

nected to an accessory subbase or factory approved air condition- ing coil casing. DO NOT cut main furnace casing to attach supply

side air duct, humidifier, or other accessories. All accessories

MUST be connected external to furnace main casing. HORIZONTAL FURNACES

Connect supply-air duct to supply air opening on furnace. The

supply-air duct attachment must ONLY be connected to furnace supply/outlet or air conditioning coil casing (when used). DO NOT cut main furnace casing to attach supply side air duct, humidifier•

or other accessories. All accessories MUST be connected external to furnace main casing.

Step 4,--Return Air Connections

UPFLOW FURNACES The return-air duct must be connected to bottom • sides (left or

right), or a combination of bottom and side(s) of main furnace casing as shown in Fig. 1. Bypass humidifier may be attached into

unused side return air portion of the furnace casing. DO NOT connect any portion of return-air duct to back of furnace casing.

DOWNFLOW AND HORIZONTAL FURNACES The return-air duct must be connected to return-air opening provided as shown in Fig. 1. DO NOT cut into casing sides or back

to attach any portion of return-air duct. Bypass humidifier connec- tions should be made at ductwork or coil casing sides exterior to

furnace.
