Important Information

Addendum to the Installation, Start-up, and Operating and

Maintenance Instructions

Series 110 or Series B 33 1/3” Mid-Efficiency Furnaces

This furnace is equipped with the White-Rodgers Series G valve. This instruction

sheet is to familiarize you with Series G gas valve and to be used to check and

adjust gas pressure for proper installation and start-up.

This sheet will be used to complete the “Adjustments” section of the “Start-up Procedures”

section of the Installation, Start-up, Operating and Maintenance Instructions.

See Fig. 1 for two-stage gas valve. This version of the G valve has standard 1/8” NPT inlet and

outlet pressure taps that are removed with a 3/16” hex head wrench for connection to a

manometers and Low Gas Pressure Switch (when used). For conversions to propane gas, refer to

the instructions in the Natural to Propane Conversion Kit, KGANP3001ALL.

. 1-Two-Sta

e Gas Valve

The major difference in the two-stage G valve, besides the compact design, is the location of the

Low and High stage regulators. Both regulators are located on top of the valve and are marked

“Lo” and “Hi” next to the regulator seal caps. Both regulator springs are adjusted with a standard

3/16” or smaller flat-tipped screwdriver.

The other difference is the G series valve IS NOT a dual-fuel gas valve. Conversions to propane

will require the replacement of BOTH regulator adjustment springs. The Low stage and High

stage springs are identical to each other and the 2 springs are included in the Natural to Propane

Conversion Kit, KGANP3001ALL

IMPORTANT:

This sheet MUST be inserted into the Installation, Start-up, Operating and Maintenance

Instructions and left with the furnace.

ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS

PROCEDURE

FURNACE RELIABILITY HAZARD

Improper installation or service of furnace may cause prema-

ture furnace component failure.

Electrostatic discharge can affect electronic components.

Follow the Electrostatic Discharge Precautions Procedure

listed below 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. Multiple disconnects may

be required. DO NOT TOUCH THE CONTROL OR ANY

WIRE CONNECTED TO THE CONTROL PRIOR TO DIS-

CHARGING YOUR BODY’S ELECTROSTATIC CHARGE

TO GROUND.

2. Firmly touch the 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 to

recharge 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 (and recharge your body with

static electricity), firmly touch a clean, unpainted metal

surface of the 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 4 before bringing the control

or yourself in 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

GENERAL

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in personal injury

or death, and furnace damage.

Corrosive or contaminated air may cause failure of parts

containing flue gas, which could leak into the living space.

Air for combustion must not be contaminated by halogen

compounds, which include fluoride, chloride, bromide, and

iodide. These elements can corrode heat exchangers and

shorten furnace life. Air contaminants are found in aerosol

sprays, detergents, bleaches, cleaning solvents, salts, air

fresheners, and other household products. Do not install

furnace in a corrosive or contaminated atmosphere. Make

sure all combustion and circulating air requirements are met,

in addition to all local codes and ordinances.

The following types of furnace installations may require OUT-

DOOR AIR for combustion due to chemical exposures:

• Commercial buildings

• Buildings with indoor pools

• Laundry rooms

• Hobby or craft rooms, and

• Chemical storage areas

If air is exposed to the following substances, it should not be used

for combustion air, and outdoor air may be required for combus-

tion:

• Permanent wave solutions

• Chlorinated waxes and cleaners

• Chlorine based swimming pool chemicals

• Water softening chemicals

• De-icing salts or chemicals

• Carbon tetrachloride

• Halogen type refrigerants

• Cleaning solvents (such as perchloroethylene)

• Printing inks, paint removers, varnishes, etc.

• Hydrochloric acid

• Cements and glues

• Antistatic fabric softeners for clothes dryers

• Masonry acid washing materials

All fuel-burning equipment must be supplied with air for fuel

combustion. Sufficient air must be provided to avoid negative

pressure in the equipment room or space. A positive seal must be

made between the furnace cabinet and the return-air duct to

prevent pulling air from the burner area and from draft safeguard

opening.

FIRE, INJURY OR DEATH HAZARD

Improper location or inadequate protection could result in fire

or explosion.

When the furnace is installed in a residential garage, the

burners and ignition sources must be located at least 18 inches

above the floor. The furnace must be located or protected to

avoid damage by vehicles. When the furnace is installed in a

public garage, airplane hangar, or other building having a

hazardous atmosphere, the furnace must be installed in

accordance with the NFGC or NSCNGPIC. (See Fig. 5.)

PERSONAL INJURY AND/OR PROPERTY DAMAGE

HAZARD

Improper use or installation of this furnace can cause prema-

ture component failure.

This gas furnace may be used for construction heat provided

that:

-The furnace is permanently installed with all electrical

wiring, piping, 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 no less

than 55 degrees F, 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 gas input rate has been set to the

nameplate value.

-The filters used to clean the circulating air during the

construction 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.

-Verify proper furnace operating conditions including igni-

tion, gas input rate, air temperature rise, and venting accord-

ing to these installation instructions.

FIRE, INJURY, OR DEATH HAZARD

Failure to follow this warning could result in unsafe furnace

operation.

Do not install the furnace on its back or hang furnace with

control compartment facing downward. Safety control opera-

tion will be adversely affected. Never connect return-air ducts

to the back of the furnace. (See Fig. 6.)

LOCATION RELATIVE TO COOLING EQUIPMENT

The cooling coil must be installed parallel with, or on the

downstream side of the unit to avoid condensation in the heat

exchangers. When installed parallel with the furnace, dampers or

other flow control must prevent chilled air from entering the

furnace. If the dampers are manually operated, they must be

equipped with means to prevent operation of either unit unless the

damper is in the full-heat or full-cool position.

AIR FOR COMBUSTION AND VENTILATION

Provisions for adequate combustion, ventilation, and dilution air

must be provided in accordance with:

U.S. installations: Section 8.3 of the NFGC, Air for Combustion

and Ventilation, and applicable provisions of the local building

codes.

Canadian installations: Part 7 of the NSCNGPIC, Venting

Systems and Air Supply for Appliances and all authorities having

jurisdiction.

FURNACE CORROSION HAZARD

Failure to follow this caution may result in furnace damage.

Air for combustion must not be contaminated by halogen

compounds, which include fluoride, chloride, bromide, and

iodide. These elements can corrode heat exchangers and

shorten furnace life. Air contaminants are found in aerosol

sprays, detergents, bleaches, cleaning solvents, salts, air

fresheners, and other household products.

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in personal injury

or death.

The operation of exhaust fans, kitchen ventilation fans,

clothes dryers, attic exhaust fans or fireplaces could create a

NEGATIVE PRESSURE CONDITION at the furnace.

Make-up air MUST be provided for the ventilation devices, in

addition to that required by the furnace. Refer to Carbon

Monoxide Poisoning Hazard warning in venting section of

these instructions to determine if an adequate amount of

make-up air is available.

The requirements for combustion and ventilation air depend upon

whether or not the furnace is located in a space having a volume

of at least 50 cubic feet per 1,000 Btuh input rating for all gas

appliances installed in the space.

• Spaces having less than 50 cubic feet per 1,000 Btuh require

the OUTDOOR COMBUSTION AIR METHOD.

• Spaces having at least 50 cubic feet per 1,000 Btuh may use the

INDOOR COMBUSTION AIR, STANDARD or KNOWN-

AIR INFILTRATION METHOD.

Outdoor Combustion Air Method

1. Provide the space with sufficient air for proper combustion,

ventilation, and dilution of flue gases using permanent hori-

zontal or vertical duct(s) or opening(s) directly communicat-

ing with the outdoors or spaces that freely communicate with

the outdoors.

2. Fig. 7 illustrates how to provide TWO OUTDOOR OPEN-

INGS, one inlet and one outlet combustion and ventilation air

opening, to the outdoors.

a. One opening MUST commence within 12″(300 mm) of

the ceiling and the second opening MUST commence

within 12″(300 mm) of the floor.

b. Size openings and ducts per Fig. 7 and Table 2.

c. TWO HORIZONTAL DUCTS require 1 square inch of

free area per 2,000 Btuh (1,100 mm

/kW) of combined

input for all gas appliances in the space per Fig. 7 and Table

d. TWO OPENINGS OR VERTICAL DUCTS require 1

square inch of free area per 4,000 Btuh (550 mm

/kW) for

combined input of all gas appliances in the space per Fig.

7 and Table 2.

3. ONE OUTDOOR OPENING requires:

a. 1 square inch of free area per 3,000 Btuh (734 mm

/kW)

for combined input of all gas appliances in the space per

Table 2 and

b. Not less than the sum of the areas of all vent connectors in

the space.
