User's Information Manual

DEATH, PERSONAL INJURY AND/OR PROPERTY DAMAGE HAZARD

Failure to observe and follow Cautions, Warnings

and instructions could result in death, bodily injury or property damage.

Read this manual and follow its instructions and adhere to all Cautions and Warnings in the manual

and on the furnace.

Consult a qualified service agency for

installation, adjustment and maintenance.

SafetyRules

Your furnace is built to provide many years of safe and depend- able service providing it is properly installed and maintained.

However,abuse and/or improper use can shorten the life of the furnace and create hazards for you, the owner.

A. The U.S. Consumer Product Safety Commission recom-

mends that users of gas-burning appliances install carbon monoxide detectors. There can be various sources of car-

bon monoxide in a building or dwelling. The sources could be gas-fired clothes dryers, gas cooking stoves, water

heaters, furnaces, gas-fired fireplaces, wood fireplaces, and several other items. Carbon monoxide can cause seri-

ous bodily injury and/or death. Carbon monoxide or"CO" is a colorless and odorless gas produced when fuel is not

burned completely or when the flame does not receive suf- ficient oxygen.

Therefore, to help alert people of potentially dangerous carbon monoxide levels, you should have carbon monox- ide detectors that are listed as complying with a standard by a nationally recognized agency (e.g. ANSI/UL

2034-2002, CSA 6.19-01, or International Approval Ser- vices 6-96) installed and maintained in the building or dwelling (see Note below).

B. There can be numerous sources of fire or smoke in a build-

ing or dwelling. Fire or smoke ca n cause serious bodily inju- ry, death, and/or property damage. Therefore, in order to

alert people of potentially dangerous fire or smoke, you should have fire and smoke detectors that are listed by Un-

derwriters Laboratories installed and maintained in the building or dwelling (see Note below).

Note: The manufacturer of your furnace does not test any de-

tectors and makes no representations regarding any brand or type of detector.

C. To ensure safe and efficient operation of your furnace, you

should do the following:

1. Thoroughly read this manual and labels on the fur- nace. This will help you understand how your furnace oper-

ates and the hazards involved with gas and electricity.

2. The furnace area must be kept clear and free of com- bustible materials, gasoline, and other flammable va- pors and liquids.

3. Do not use this furnace if any part has been underwa- ter. A flood-damaged furnace is extremely dangerous. At- tempts to use the furnace can result in fire or explosion. Immediately call a qualified service agency to inspect the

furnace and to replace all control system parts, electrical parts, and gas controls which have been wet or the furnace,

if deemed necessary.;

44102 201004

4. Never block or obstruct the openings on the furnace, or any ducts that provide air to the furnace. Air must be

provided for proper and safe operation of the furnace for combustion and ventilation of flue gases. See the "Com-

bustion Air (Your Safety) section of this manual.

5. Familiarize yourself with the possible air starvation signals. These are outlined in the Combustion Air section.

6. Check the combustion air supply. Some models use air drawn from outdoors, See Figure 4. Other models and oth-

er appliances use combustion air from inside the structure. Air starvation signals are given in the following "Combus-

tion Air (Your Safety)" section of this manual. If any of the signals are noticed, perform a combustion air check as shown in the following Combustion Air Checks section of this manual or call a qualified service agency. If you add

weather stripping, storm windows, insulation, an additional fuel burning appliance, or remodel the structure, a combus-

tion air check MUST be accomplished after the addition

7. Maintain safety and service clearances from the fur- nace. These clearances are listed on the furnace rating

plate. Keep the furnace area clean and free of combustible materials at all times. Never store gasoline, paint, aerosol cans, waxes, bleaches, dry cleaning fluid or items such as paper or rags near the furnace.

8. Examine the furnace area when the furnace or addi- tional insulation is added since some insulation mate-

rials may be combustible. Furnace must be kept free and clear of exposed or loose insulation materials in the area of

installation.

9. Check the return air duct connection. The duct connec- tion must be physically sound, sealed to the furnace casing

and must terminate outside the space containing the fur- Race.

10.Should the gas supply fail to shut off or if overheating occurs, shut off the gas valve to the furnace before

shutting offthe electrical supply. Read the label on the front of the furnace and the Operating Your Furnace sec- tion of this manual for steps to turn off the furnace.

11.Familiarize yourself with all controls. Make sure you know how to shut off the gas and the electrical power to the

furnace. Read the label on the front of the furnace and the Operating Your Furnace section of this manual for steps to

start and turn off the furnace. If the furnace is to be shut down for an extended length of time (example; remodeling project), turn off both the gas and the electrical power. For

safety, always turn them off before performing service or maintenance on the furnace.

12. Establish a regular service and maintenance sched- ule. This will ensure efficient and safe operation of the fur-

nace. It is recommended that you have a qualified service agency perform a complete check on the furnace before

each heating season. See furnace Qualified Agency

Checks and Combustion Air Checks section of this manu-

al.

13. Monthly Inspection. A properly adjusted gas furnace should not require cleaning at frequent intervals, but it

should be inspected regularly to ensure safe and efficient operation. A brief monthly inspection is recommended that does not require disassembly. Examine the furnace instal-

lation to determine that:

a. All flue gas carrying areas external to the furnace (i.e.

chimney, vent connector) are clear and free of obstruc- tions.

b. The vent connector is in place, slopes upward and is

sound without holes or excessive corrosion.

User's Information Manual

c. (Upflow or downflow installations with duct connection

at bottom only.) The physical support of the furnace is sound without sagging, cracks, gaps, etc., around the

base so as to provide an air seal between the support and the base.

d. There should be no obvious signs of deterioration of the

furnace.

e. Check that the pilot and burner flames are in good ad-

justment. To inspect the Pilot and Main Burner flames it

will be necessary to remove the Iouvered door on the

front of the furnace, except for furnaces not having any louvers in the doors. The doors of these furnaces must

remain installed (to prevent changes in flame appear- ance) while inspecting the Pilot and Main Burner flames through the view port in the door. Contact a qualified service agency at once if an abnormal flame appear-

ance is identified. Main Burner Flame: Check for the following:

• Stable and blue flames. See Figure 1.

• Flames extending directly from burner into heat exchanger.

• Flames do NOT touch sides of heat exchanger.

NOTE: Dust may cause orange tips or wisps of yellow, but flames MUST NOT have solid, yellow tips.

Combustion Air (Your Safety)

CARBON MONOXIDE POISONING HAZARD

Lack of combustion air could result in carbon monoxide gas which could cause death or seri-

ous bodily injury.

All fuel-burning appliances must be provided with enough fresh air for proper combustion and ventilation of flue gases.

Some models use air from the space in which

they are located, and other appliances in the

same space may also be using indoor air for ven-

tilation and/or combustion.

10-10-78

• Check main burner flames monthly.

Pilot Burner Flame: While the main burner is ON, the flame should envelop the upper part of the Flame Sen-

sor, as shown in Figure 2.

f. With the equipment shutoff valve turned OFF, remove

the burner compartment door of the furnace to use a flashlight to inspect the visible parts of the burners and igniter. Check for loose soot and give particular atten-

tion to obvious deterioration from corrosion or other sources. If soot or deterioration is found inside the fur- nace, DO NOT OPERATE FURNACE; call a qualified service agency.

g. Inspect the drain line and overflow line monthly (con-

densing furnace and/or air conditioning cooling coil at- tached to furnace).

New materials and methods are being used in construction and remodeling which result in lower energy costs for heating and

cooling. It may also mean your appliances may not be getting enough air for combustion and ventilation of flue gases. The use of exhaust fans, fireplaces, clothes dryers, and other appliances

consume air or vent it to the outdoors. If the gas appliances or heating furnace can't get enough air, two

conditions may result:

1. The appliances or furnace may produce carbon monoxide gas.

2. The appliance may not vent flue gases properly. The fol- lowing are signs that your appliances may not be getting

enough air for proper combustion.

Be aware of these signals;

1. Headaches-Nausea-Dizziness

2. Excessive humidity-heavily frosted windows or a moist "clammy" feeling in the structure.

3. Smoke from the fireplace won't draw up the chimney.

User's Information Manual

CARBON MONOXIDE POISONING HAZARD. Carbon monoxide poisoning could result in death

from asphyxiation or serious bodily injury.

If you experience headaches, nausea, or dizziness, carbon monoxide may be present.

Leave the house immediately and call your gas supplier.

Combustion Air Checks

If any of the above signals are noticed, perform a combustion air check or call a qualified service agency. If you add weather strip- ping, storm windows, insulation, an additional fuel burning ap-

pliance, or remodel the structure, a combustion air check MUST be accomplished after the addition.

Make the inspection as follows:

1. Close all doors and windows. If you have a fireplace, start a fire and wait until flames are burning vigorously.

2. Turn on all exhausting devices, such as: kitchen and bath- room exhaust fans and dryers (gas or electric).

3. Turn on all vented gas appliances, such as: heating equip- ment (includes any room heaters) and water heaters.

4. Wait ten (10) minutes for drafts to stabilize.

5. On appliances with a draft hood, check for spillage by hold- ing a lighted match 2" from the draft hood opening. Refer-

ence Figure 3, which shows a water heater draft hood.

Water Heater Draft Hood

Vent Pipe _---L / Draft Hood

f --=/

If draft hood spillage is indicated:

1. Check for plugged vent connectors and chimneys. Repair stoppage and test again.

2. Ifyou have a fireplace, open a windowor door near the fire- place and then check for spillage.

If spillage stops, do not use the fireplace until you can sup- ply fresh air by a permanent duct.

3. If you have kitchen and bathroom exhaust fans, turn them OFF and check for spillage.

If spillage stops, do not use exhaust fans until you can sup- ply fresh air by a permanent duct. Circuit breakers for fans should be turned off and marked as to why they are off.

4. Spillage means air starvation and that an outdoor air duct or air intake must be installed to provide air directly to the area around the furnace. This duct or intake MUST comply

with local and state building codes or in their absence with the National Fuel Gas Code NFPA 54/ANSI Z223.1-2002

in the U.S., or the National Standard of Canada, Natural Gas and Propane Installation Code CSA B-149.1-00 in

Canada.

IndoorHumidity(YourComfort)

Relative humidity is important to your health. Proper humidifica- tion helps cut down incidences of respiratory illness. Air that istoo

wet may damage the building structure. Air that is too dry is un-

comfortable. A quick way to test for proper humidity is as follows:

Look for frequent fogging or excessive condensation on the inside of windows. This indicates the indoor humidity

level is too high for outdoor weather conditions.

Drop three ice cubes into a glass of water and stir. If, within three minutes, moisture does not form on the glass, the air

is too dry and a humidifier would be beneficial. (Do not per- form this test in the kitchen, cooking vapors may produce

inaccurate results.)

A good relative humidity is one just high enough to barely start condensation along the lower edges or lower corners of the win- dows, when it is cold outside. More than that can be damaging.

A. Match flame pulls toward draft hood.

This indicates no spillage and that appliance is getting enough air for combustion. Return exhausting devices and

appliances to the condition in which you found them.

B. Match goes out or flame wavers away from draft hood. This

indicates spillage and that appliance is not getting enough air for combustion.

CARBON MONOXIDE POISONING HAZARD. Carbon monoxide poisoning could result in death

from asphyxiation or serious bodily injury. Draft hood spillage means there is not enough air

for proper combustion and carbon monoxide may

be present.

Keep a window open (a minimum of 2" ) near the

appliance until a permanent combustion air duct

is installed. Contact a qualified service agency.

441 02 2010 04

If the humidity is too high, try these suggestions to lower the hu- midity:

1. Reduce setting or discontinue use of humidifier.

2. Use range and bathroom exhaust fans while cooking and bathing. Open a door or window for a few minutes to bring

in cool drier air.

3. Cook with pans covered.

4. Take shorter baths or showers with cooler water.

5. Install a fresh air intake duct. Cold, dry air brought in from outside to the furnace area lowers the indoor humidity lev-

el.

6. Have appliances checked. A malfunctioning appliance can contribute water vapor to the structure.

7. If the problem continues, consult a heating contractor about adding a heat recovery ventilator or air-to-air heat exchanger.
