Carrier A10247 Important Facts DOS and Donts, Before Starting Your Furnace, Safety Considerations

IMPORTANT FACTS (DO'S AND DON'TS)

•DO: READ AND UNDERSTAND THIS MANUAL

•DO: Have your furnace and vent system inspected annually by a qualified service technician.

•DO: Inspect your filter monthly and clean or replace when needed.

•DO: Provide adequate airflow to the furnace for efficient

combustion and safe ventilation.

•DO: Keep your furnace free and clear of insulating material.

Some materials may be combustible. Examine the furnace area when the furnace is installed or when insulation is added.

•DO NOT: Enclose your furnace in an airtight room or seal it behind solid doors.

•DO NOT: Keep combustible materials, gasoline, and other

flammable liquids or vapors around your furnace.

•DO NOT: Cover your furnace in any manner.

•DO NOT: Store anything (including trash or debris) near your furnace.

•DO NOT: In any way block or restrict airflow around your furnace.

•DO NOT: In any way block or restrict airflow to your supply air and return air grills.

•DO NOT: Use your furnace room as a broom closet or a place to store any kind of chemical or cleaner.

•DO NOT: Contaminate the air used for combustion of your furnace with any kind of chemical or fumes. This could also

cause heat exchangers, metal vent systems or components to deteriorate.

NOTE: These chemicals or fumes are present in many products

around the home, such as: water softener salts, any type of

household cleaning product, any type of laundry product,

adhesives, paints, varnishes, paint strippers, waxes and plastics, etc.

During remodeling be sure the combustion air is fresh and

uncontaminated. If these compounds are burned in your furnace,

the heat exchangers and metal vent system may deteriorate.

NOTE: The qualified installer or agency must use only

factory-authorized replacement parts, kits, and accessories when

modifying this product.

This furnace contains safety devices which must be manually reset.

If the furnace is left unattended for an extended period of time,

have it checked periodically for proper operation. This precaution will prevent problems associated with no heat, such as frozen water pipes, etc. See "Before You Request a Service Call" section in this manual.

FIRE OR EXPLOSION HAZARD

Failure to follow this safety warning could result in injury, death, or property damage.

Do not keep combustible materials, gasoline, and other

flammable liquids or vapors around your furnace.

FIRE OR EXPLOSION HAZARD

Failure to follow safety warnings could result in personal

iniury, death, or property damage.

Keep insulation clear of furnace and maintain clearances shown on unit clearance label.

BEFORE STARTING YOUR FURNACE

Examine the furnace installation to determine that:

1.All flue gas carrying areas external to the furnace (i.e. china-

ney, vent connector) are clear and free of obstructions.

2.The vent connector is in place, slopes upward and is physic- ally sound without holes or excessive corrosion.

3.The return-air duct connection(s) is physically sound, is

sealed to the furnace casing, and terminates outside the

space containing the furnace.

4.The physical support of the furnace is sound without sag- ging cracks, gaps, etc. around the base.

5.There are no obvious signs of deterioration of the furnace.

SAFETY CONSIDERATIONS

Installing and servicing heating equipment can be hazardous due to

gas and electrical components. Only trained and qualified personnel should install, repair, or service heating equipment.

Untrained personnel can perform basic maintenance functions such

as cleaning or replacing air filters. All other operations must be

performed by trained service personnel. Observe safety precautions in this manual, on tags, and on labels attached to the furnace, and

other safety precautions that may apply.

Recognize safety information. This is the safety-alert symbol /_.

When you see this symbol on the furnace and in instructions or manuals, be alert to the potential for personal iniury.

Understand the signal words DANGER, WARNING, and

CAUTION. These words are used with the safety-alert symbol.

DANGER identifies the most serious hazards which will result in

severe personal iniury or death. WARNING signifies hazards

which could result in personal iniury or death. CAUTION is used

to identify unsafe practices which would result in minor personal iniury or product and property damage. NOTE is used to highlight

suggestions which will result in enhanced installation, reliability or operation.
