User's Information Manual

Read this manual and follow its instructions and ad- here to all Cautions and Warnings in the manual and

on the unit.

Consult a qualified service technician for installa- tion, adjustment and maintenance.

Failure to observe and follow Cautions, Warnings and instructions may result in death, bodily injury or property damage.

Safety Rules

Your unit is built to provide many years of safe and dependable service providing it is properly installed and maintained. Howev-

er, abuse and/or improper use can shorten the life of the unit 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

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

ter heaters, furnaces, gas--fired fireplaces, wood fire- places, and several other items. Carbon monoxide can

cause serious bodily injury and/or death. Therefore, to help alert people of potentially dangerous carbon monoxide lev- els, you should have carbon monoxide detectors listed by a nationally recognized agency (e.g. Underwriters Laborato-

ries or International Approval Services) installed and maintained in the building or dwelling (see Note below).

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

building or dwelling. Fire or smoke can cause serious bodily injury, death, and/or property damage. Therefore, in order to alert people of potentially dangerous fire or smoke, you

should havefire andsmoke detectors listed by Underwriters Laboratories installed and maintained in the building or dwelling (see Note below).

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

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

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

should do the the following:

1. Thoroughly read this manual and labels on the unit. This will help you understand how your unit operates and the hazards involved with gas and electricity.

2. D° n°t usethis unit if any part has been under water" Irn mediately call a qualified service technician to inspect the unit and to replace any part of the control system and any gas control which has been under water.

3. Never obstruct the vent grilles, or any ducts that provide air to the unit. Air must be provided for proper combustion and ventilation of flue gases.

4. Familiarize yourself with the possible air starvation sig- nals. These are outlined in the Combustion Air section.

Check the combustion air supply. Some models use air drawn from outside, See Figure 3. Other models and other

appliances use combustion air from inside the structure. Air starvation signals are given on this page. If any of the sig- nals are noticed, perform a combustion air check as shown on page 4 or call a service technician. If you add weather

stripping, storm windows, insulation, an additional fuel burning appliance, or remodel the structure, a combustion

air check MUST be accomplished after the addition

441 02 2001 07

6. Maintain safety and service clearances from the unit. These are listed on Unit Clearance Label on the cabinet.

Keep the unit 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 unit.

7. Examine the furnace area when the furnace or addi- tional insulation is added since some insulation materi-

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

installation.

8. 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 furnace.

9. Familiarize yourself with all controls. Make sure you know how to shut off the gas and the electrical power to the unit. If the unit 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 themoff before performing service or maintenance on the unit.

10. Establish a regular service and maintenance schedule. This will ensure efficient and safe operation of the unit. It is recommendedthat youhavea qualified service agency

perform a complete check on the unit before each heating season. See unit Maintenance "Service Technician

Checks". Combustion Air ( Your Safety)

Combustion Air ( Your Safety)

All fuel-burning appliances must be provided with enough fresh air for proper combustion and ventila-

tion 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 ventilation and/or

combustion.

Lack of combustion air will result in carbon monox- ide gas which could cause death or serious bodily

injury.

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. Theuse of exhaust fans, fireplaces, clothes dryers, and other appliances

consume air or vent it outside. If the appliances or heating unit can't get enough air, two condi-

tions may result:

1. The appliance or heating unit may produce carbon monox- ide gas.

Carbon monoxide or "CO" is a colorless and odorless gas produced when fuel is not burned completely or when the

flame does not receive sufficient oxygen.

2. The appliance may not vent flue gases properly.

The following 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 "clamm_ the structure.

User's Information Manual

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

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

Leave the house immediately and call your gas sup- plier.

Carbon monoxide poisoning can result in death from asphyxiation or serious bodily injury.

Combustion Air Checks

If any of the signals are noticed, perform a combustion air check or call a service technician. If you add weather stripping, storm win-

dows, insulation, an additional fuel burning appliance, or remodel the structure, a combustion air check MUST be accomplished af-

ter 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 inches from the draft hood opening.

Reference Figure 1 which shows a water heater draft

hood.

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

If draft hood spillage is indicated:

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

2. If you have a fireplace, open a window or door near the fire- place and then check for spillage. If spillage stops, do not

use the fireplace until you can supply fresh air by a perma- nent 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.

4. Spillage means air starvation and a fresh air duct or air in- takes must be installed to provide air directly to the area

around the unit. These MUST comply with local and state building codes or in their absence with the National Fuel Gas Code NFPA 54 ANSI Z223.1, current edition or in Can- ada the National Standard CAN/CGA 1-B149.

Indoor Humidity (Your Comfort)

Relative humidity is important to your health. Proper humidification

helps cut down incidences of respiratory illness. Air that is too wet may damage the building structure. Air that is too dry is uncomfort- able. A quick way to test for proper humidity is as follows:

1. 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.

2. 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 perform this test in the kitchen, cooking vapors may produce inaccu-

rate results.)

A good relative humidity is one just high enough to barely start con- densation along the lower edges or lower corners of the windows,

when it is cold outside. More than that can be damaging. If the humidity is too high, try these suggestions to lower the humid-

ity:

Reduce setting or discontinue use of humidifier.

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 unit area lowers the indoor humidity level.

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

7. Ifthe problem continues, consult a heating contractor about adding a heat recovery ventilator or air to air heat exchang-

er.

About Your Unit

Draft hood spillage means there is not enough air

for proper combustion and carbon monoxide may

be present. Keep awindow open (a minimum of 2") near the ap-

pliance until a permanent air duct is installed. Con-

tact a qualified service agency. Carbon monoxide poisoning can result in death

from asphyxiation or serious bodily injury.

Figure 2 shows the location of the components in the unit.

Circulating Air Blower

The blower circulates room air through the unit, air ducts, and into the rooms of the structure. The blower can be set at the thermostat

for automatic or manual operation. In manual mode the blower op- erates continuously. In automatic, the blower does not come on

until a preset time after the gas valve is energized. When the struc- ture reaches the temperature set on the thermostat, the unit will

shut off. The blower will continue to run until the unit cools down.
