create hazards for you, the owner.

A. The U.S. Consumer Product Safety Commissionrecom-

mends that users of gas--burning appliances installcar-

bon 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, water heaters, furnaces, gas--fired fireplaces,

wood fireplaces, and several other items. Carbon mon-

oxidecancauseseriousbodilyinjuryand/ordeath. Car-

bon 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.

Therefore, to help alert people of potentially dangerous

carbon monoxide levels, you should have carbon mon-

oxide detectors that are listed as complying with a stan-

dard 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. Therecanbenumeroussourcesoffireorsmokeinabuilding

Combustion Air (Your Safety)

CARBON MONOXIDE POISONING HAZARD

Lack of combustion air could result in carbon

monoxide gas which could cause death or serious

personal 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

arelocated,andotherappliancesinthesamespace

may also be using indoor air for ventilation and/or

combustion.

!WARNING

Itmayalsomeanyourappliancesmaynotbegettingenough airfor

combustion and ventilation of flue gases. The use of exhaustfans,

fireplaces,clothesdryers,andotherappliancesconsumeairorvent

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 gasesproperly. The follow-

ingaresignsthatyourappliancesmaynotbegettingenough

air for proper combustion.

Be aware of these signals;

1. Headaches--Nausea--Dizziness

2. Excessive humidity--heavily frosted windows ora moist

“clammy” feeling in the structure.

3. Smoke from the fireplace won’t draw up the

chimney.

CARBON MONOXIDE POISONING HAZARD.

Carbon monoxide poisoning could result in death

from asphyxiation or serious personal injury.

If you experience headaches, nausea, or

dizziness, carbon monoxide may be present.

Leave the house immediately and call your gas

supplier.

RNING

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,orremodelthestructure,acombustionaircheckMUSTbe

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. Onapplianceswithadrafthood,checkforspillagebyholding

CARBON MONOXIDE POISONING HAZARD.

Carbon monoxide poisoning could result in death

from asphyxiation or serious personal 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 2²

²²

²) near the

appliance until a permanent combustion air duct is

installed. Contact a qualified service agency.

!WARNING

If draft hood spillage is indicated:

1. Check for plugged vent connectors and chimneys. Repair

stoppage and test again.

2. If you have a fireplace, open a windowor door near thefire-

place and then check for spillage.

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

aroundthefurnace.ThisductorintakeMUSTcomplywithlo-

cal and state building codes or in their absence with theNa-

tional 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.

Indoor Humidity (Your Comfort)

Relativehumidityis importantto yourhealth. Properhumidification

helps cut down incidences of respiratory illness. Air that is too wet

may damage thebuilding structure. Air that is toodry is uncomfort-

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

1. Look for frequent fogging or excessive condensation on the

insideofwindows.This indicates theindoorhumidity levelis

too high for outdoor weather conditions.

2. Drop three ice cubes into a glass of water and stir. If, within

threeminutes,moisturedoesnotformontheglass,the airis

toodryanda humidifierwouldbebeneficial.(Donotperform

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

rate results.)

Agoodrelativehumidityisonejusthighenoughtobarelystartcon-

densation along the lower edges or lower corners of the windows,

when it is cold outside. More than that can be damaging.

Ifthehumidityistoohigh,trythesesuggestionstolowerthehumid-

ity:

1. Reduce setting or discontinue use of humidifier.

2. Use range and bathroom exhaust fans while cooking and

bathing. Open a door or window fora few minutes to bringin

cool drier air.

3. Cook with pans covered.

4. Take shorter baths or showers with cooler water.

5. Installafreshairintakeduct.Cold,dryairbroughtinfromout-

side to the furnace area lowers the indoor humidity level.

6. Have appliances checked. A malfunctioning appliance can

except as permitted below.

Ifacleanable(high--velocity)filter(s)istobereplacedwithadispos-

able (low--velocity) filter(s), the airflow area of the filter(s) must be

doubled (i.e., a second filter of the same size must be installed so

thatonlyhalfoftheairgoesthrougheachfilter). Asecondreturn--air

duct to the furnace may be required in which to install the second

filter. Modification ofa furnace installation shall comply with the lo-

cal installation code and the furnace installation instructions, and

shall be made only by a Qualified Service Agency.

NOTE: Some filters are marked with an arrow to indicate the

properdirectionofairflowthroughthefilter. Theairflowdirec-

tion will be towards the blower motor. Make sure filter is

installed correctly.

Filter Replacement -- Upflow

The filter may be installed inside the bottom of the furnace blower

compartment,orthefilter(s)rackmaybeinstalledunderthefurnace

or on either or both sides of the furnace. A plastic end cap(s) is in-

serted in the filter rack(s) after the filter(s) is installed. The end cap

keepsairfromescaping aroundtheopen end of the filterrack. See

Figure 7andFigure 8forsideandbottomlocations.Rackendcap

is similar for bottom mounted filter rack.

Filter rack(s) attached to the outside of the furnace is made sothe

filter simply slides out one end for removal.

RISK OF REDUCED FURNACE LIFE

Use of excessively dirty and/or restrictive air

filters may increase furnace operating

temperatures and shorten the life of the furnace.

Filters specified for the furnace are rated at a

maximum of 600 FPM air velocity and sized for the

furnace’s airflow rate. Replacement filters must be of

equivalent type, size, and rating except as described

below.

Disposable, low--velocity filters may be used to replace

washable, high--velocity filters, providing they are sized

for 300 FPM or less.

Ifyouareuncertainofthe type ofreplacement filtertouse,

consult the furnace installer or a qualified service agency

for assistance.
