CENTRAL FURNACE

A self-contained, gas burning appliance for heating air by transfer of heat of combustion through metal to the air, and designed to supply heated air through ducts to spaces remote from or adjacent to the appliance location.

CENTRAL FURNACE Down flow forced air type

A furnace designed with air flow essentially in a vertical path, discharging air at or near the bottom of the furnace.

CENTRAL FURNACE Forced air type

A central furnace equipped with a fan or blower which provides the primary means for circulation of air.

CENTRAL FURNACE Gravity type

A central furnace depending primarily on circulation of air by gravity.

CENTRAL FURNACE Gravity type with integral fan

A central furnace equipped with a fan or blower as an integral part of its construction and operable on gravity systems only. The fan or blower is to be used only to overcome the internal furnace resistance to air flow.

CENTRAL FURNACE Horizontal forced air type

A furnace designed for low headroom installation with air flow through the appliance essentially in a horizontal path.

CENTRAL FURNACE Up flow forced air type,

A furnace designed with air flow essentially in a vertical path, discharging air at or near the top of the furnace.

CENTRAL HEATING GAS APPLIANCE

A vented gas-fired appliance comprising the following classes as defined herein: boiler, central furnace, floor furnace, or vented wall furnace.

CHIMNEYS Factory-built chimneys

Chimneys that are factory made, listed by a nationally recognized testing agency, for venting gas appliances, gas incinerators, and solid or liquid fuel burning appliances.

CIRCUIT VENT

A vent that connects to a horizontal drainage branch and vents two traps to a maximum of eight traps or trapped fixtures connected into a battery.

CISTERN

A small covered tank for storing water for a home or farm. Generally, this tank stores rainwater to be utilized for purposes other than in the potable water supply, and such tank is placed underground in most cases.

CLEANOUT

An access opening in the drainage system utilized for the removal of obstructions. Types of cleanouts include a removable plug or cap, or a removable fixture or fixture trap.

CLOSED WATER PIPING SYSTEM

A system of water piping where a check valve or other device prevents the free return of water or steam to the water main.

CLOTHES DRYER

A device used to dry wet laundry by means of heat derived from the combustion of fuel gases.

CLOTHES DRYER Type 1

Factory-built package, multiple produced. Primarily used in family living environment. Mayor may not be coin-operated for public use. Usually the smallest unit physically and in function output.

CLOTHES DRYER Type 2

Factory-built package, multiple produced. Used in business with direct intercourse of the function with the public. Mayor may not be operated by the public or hired attendant. Mayor may not be coin operated. Not designed for use in individual family living environment. May be small, medium or large in relative size.

CODE

CODE OFFICIAL

The officer or other designated authority charged with the administration and enforcement of this code, or a duly authorized representative.

COMBINATION FIXTURE

A fixture combining one sink and laundry tray or a two- or three-compartment sink or laundry tray in one unit.

COMBINATION WASTE AND VENT SYSTEM

A specially designed system of waste piping embodying the horizontal wet venting of one or more sinks or floor drains by means of a common waste and vent pipe adequately sized to provide free movement of air above the flow line of the drain.

COMBINED BUILDING DRAIN

See "Building drain, combined."

COMBINED BUILDING SEWER

See "Building sewer, combined."

COMBUSTIBLE CONSTRUCTION

A wall or surface constructed of wood, composition, or of wooden studding and lath and plaster.

COMBUSTION

The rapid oxidation of fuel gases accompanied by the production of heat, or heat and light.

COMBUSTION CHAMBER

The portion of an appliance within which combustion occurs.

COMBUSTION PRODUCTS

Constituents resulting from the combustion of a fuel with the oxygen of the air, including the inerts but excluding excess air.

COMMON VENT

A vent connecting at the junction of two fixture drains or to a fixture branch and serving as a vent for both fixtures.

CONCEALED FOULING SURFACE

Any surface of a plumbing fixture which is not readily visible and is not scoured or cleansed with each fixture operation.

CONCEALED GAS PIPING

Piping which, when in place in the finished building, would require removal of permanent construction to gain access to the piping.

CONDENSATE

The liquid which separates from a gas (including flue gas) due to a reduction in temperature. Also called condensation.

CONDENSING FURNACE

A furnace or boiler which condenses part of the water vapor generated by the burning of hydrogen in fuels and in which the fraction of the total latent heat remaining in the flue gases after condensation is less than unity.

CONDUCTOR

A pipe inside the building that conveys storm water from the roof to a storm or combined building drain.

CONFINED SPACE

A space whose volume is less than 50 cu ft per 1,000 Btu per hour (4.83 m3/kW) of the aggregate input rating of all appliances installed in that space.

CONSTRUCTION DOCUMENTS

CONTAMINATION

An impairment of the quality of the potable water that creates an actual hazard to the public health through poisoning or through the spread of disease by sewage, industrial fluids or waste.

CONTROL

A device designed to regulate the gas, air, water, or electrical supply to a gas appliance. It may be manual or automatic.

CONVERSION BURNER

A burner designed to supply gaseous fuel to an appliance originally designed to utilize another fuel.

CROSS CONNECTION

Any physical connection or arrangement between two otherwise separate piping systems, one of which contains potable water and the other either water of unknown or questionable safety or steam, gas or chemical, whereby there exists the possibility for flow from one system to the other, with the direction of flow depending on the pressure differential between the two systems.   (see "Backflow").
