FURNACE AREA
Improved construction and additional insulation in homes
have reduced the heat loss and made these homes much
tighter around doors and windows so that air infiltration is
minimal. This creates a problem to supply ventilation and/or
combustion air for gas fired or other fuel burning appliances.
Any use of appliances that pull air out of the house (clothes
dryers, exhaust fans, fireplaces, water heaters, non-direct
vent furnaces, etc.) could reduce combustion air to the fur-
nace.
If fuel-burning appliances are starved for air, the flue gases
produced may not vent outdoors properly. These flue gases
may include carbon monoxide.

POISONING
HAZARD
Special warning for i n stal l ati o n of furnaces or ai r handli n g uni t s i n enclosed areas such as garages, util i t y rooms or parki n g areas. Carbon monoxi d e producing
devi c es (such as automobi l es, space heaters, gas water heaters, etc.) shoul d not be operated i n enclosed areas such as unventi l a ted garages or util i t y rooms
because of the danger of carbon monoxide (CO) poisoni n g resulting from the exhaust emi s si o ns. If a furnace or ai r handler i s i n stall e d i n an enclosed area and a
carbon monoxi d e produci n g devi c e i s operated therein, there must be adequate direct outsi d e ventil a tion. Carbon monoxi d e emissions can be (re)ci r cul a ted
throughout the structure i f the furnace or ai r handler i s operati n g i n any mode. CO can cause serious i l l n ess i n cl u ding permanent brai n damage or death.
RISQUE D' E MPOISONNEMENT AU MONOXYDE DE CARBONE
Averti s sement speci a l au sujet de l ' i nstall a tion d' a ppareil s de chauffage ou de traitement d' a i r dans des endroi t s cl o s, tets les garages, les l o caux d' e ntreti e n et l e s
Stationnements. Evitez de mettre en marche les apparei l s produi s ant du monoxyde de carbone (tel s que l e s automobi l e, l e s apparei l s de chauffage autonome,etc.)
dans des endroits non venti l és tel s que l e s d' e mpoi s onnement au monoxyde de carbone. Si vous devez faire foncti o nner ces appareil s dans un endroi t clos,
assures-vous qu' i l y ait une venti l a ti o n directe provenant de l ' e xteri e r . Les émi s sions de monoxyde de carbone peuvent etre recircul e s dans les endroi t s cl o s,
si l ' a pparei l de chauffage ou de trai t ement d' a i r sont en marche. Le monoxyde de carbone peut causer des mal a di e s graves tel l es que des dommages permanents
au cerveau et meme l a mort.

RIESGO DE INTOXICACIÓN POR MONÓXIDO DE CARBONO
Advertencia especi a l para la instalación de calentadores ó manej a doras de ai r e en áreas cerradas como estaci o nami e ntos ó cuartos de servicio. Los equipos ó
aparatos que producen monóxi d o de carbono (tal como automóvil , cal e ntador de gas, calentador de agua por medio de gas, etc) no deben ser operados en
áreas cerradas debi d o al ri e sgo de envenenami e nto por monóxi d o de carbono (CO) que resulta de l a s emisi o nes de gases de combusti ó n. Si el equipo ó
aparato se opera en di c has áreas, debe exi s tir una adecuada ventil a ci ó n di r ecta al exteri o r. Las emi s i o nes de monóxi d o de carbono pueden ci r cul a r a través
del aparato cuando se opera en cualqui e r modo. El monóxido de carbono puede causar enfermedades severas como daño cerebral permanente ó muerte.
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.
Be aware of these air starvation signals which indicate
conditions that my result in carbon monoxide or that
carbon monoxide may be present:

PELIGRO
1. Headaches, Nausea, Dizziness, Flu-like symptoms.
2. Excessive humidity, heavily frosted windows or a moist
"clammy" feeling in the home.
3. Smoke from a fireplace will not draw up the chimney.
4. Flue gases that will not draw up the appliance vent pipe.

OMBUSTION
The air for combustion and ventilation can also (where local
codes permit) be obtained from the surrounding unconfined
space or louvered closet door. Observe the following pre-
cautions concerning air availability:
• When a furnace is installed in a closet and the closet
door is louvered, DO NOT OBSTRUCT LOUVERS. Lou-
vers must be open and clear to provide combustion air
to the furnace.
• When a furnace is installed in a confined space within a
home and the air for combustion and ventilation enters
the space through ducts from the outside, be sure to
routinely check the entering and outlet, grilled openings
to verify that they are always clear and clean.
• Do not partition off a small area around the furnace uti-
lizing a non-louvered door. This could obstruct the com-
bustion air from reaching the furnace.

NDOOR
Relative humidity is the amount of water vapor in the air rela-
tive to the amount the air can hold at the same temperature.
The colder the air; the less moisture it can hold. As air is
warmed, its ability to hold moisture is increased. Relative
humidity is important to your health and home as proper
humidification helps reduce respiratory difficulties and helps
improve the indoor air quality.
A good relative humidity is one just high enough to barely
start condensation along the lower edges or lower corners
of the windows. More than that can be damaging.
Frequent fogging or excessive condensation on inside win-
dows indicates the indoor humidity level is too high for out-
door weather conditions. Damage to the building may result
if the condition persists. Condensation on inside of storm
windows indicates a poor seal inside windows. Adding
weather-stripping to tighten inside windows usually corrects
this problem.
