Combustion Air (Your Safety) - International comfort products N9MP1 User Manual

!
Read this manual and follow its instructions and
adhere to all Cautions and Warnings in the manual
and on the unit. Consult a qualified service techni-
cian for installation, 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. However,
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 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. Therefore, to help alert
people of potentially dangerous carbon monoxide levels,
you should have carbon monoxide detectors listed by a na-
tionally recognized agency (e.g. Underwriters Laboratories
or International Approval Services) installed and main-
tained 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 can 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 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. Do not use this unit if any part has been under water. Im-
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 pro-
vide air to the unit. Air must be provided for proper com-
bustion and ventilation of flue gases.
4. Familiarize yourself with the possible air starvation sig-
nals. These are outlined in the Combustion Air section.
5. Check the combustion air supply. Some models use air
drawn from outside, See Figure 2. 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.

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 addition-
al insulation is added since some insulation materials
may be combustible. Furnace must be kept free and clear
of exposed or loose insulation materials in the area of instal-
lation.
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 fur-
nace.
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 them off be-
fore 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
recommended that you have a qualified service agency per-
form a complete check on the unit before each heating sea-
son. See unit Maintenance "Service Technician Checks".
Combustion Air ( Your Safety)
!
All fuel- -burning appliances must be provided with
enough fresh air for proper combustion and ven-
tilation 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 re-
modeling which result in lower energy costs for heating and cool-
ing. 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 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 ''clammy'' feeling in the structure .
