The air handling capacity of this furnace is designed for cooling airflow. Refer to Table 12 for expected airflows at various external duct static pressures.

LOCATION

Step 1—General

This furnace is not water tight and is not designed for outdoor installation. This furnace shall be installed in such a manner as to protect electrical components from water. Outdoor installation would lead to a hazardous electrical condition and to premature furnace failure.

Do not use this furnace as a construction heater. Use of this furnace as a construction heater exposes furnace to abnormal conditions, contaminated combustion air, and lack of air filters. Failure to follow this warning can lead to premature furnace failure and/or vent failure which could result in a fire hazard and/or bodily harm.

For attic installation, it is important to keep insulation 12 in. or more away from any furnace openings. Some types of insulating materials may be combustibles and may cause a fire hazard and property damage.

This furnace is approved for reduced clearances to combustible construction, therefore, it may be installed in a closet or similar enclosure. Since this unit may be installed in an upflow, counterflow, or horizontal position, it may be located in a basement or on the same level as area to be heated. In any case, unit should always be installed level.

In a basement, or when installed on floor (as in a crawlspace), it is recommended that unit be installed on a concrete pad that is 1 in. to 2 in. thick.

When installed in counterflow position, furnace must not be installed on combustible flooring, unless approved subbase is used. Also, since flue pipe is in a counterflow position, Downflow Conversion/Vent Guard Kit MUST be used. (Also, read page 9.)

When installed in a horizontal position, furnace may be suspended by using an angle iron frame, as long as total weight of both furnace and frame are allowed for in support calculations. (Other methods of suspending are acceptable.) When installed in the Horizontal Position, this furnace must not be installed on combustible flooring, unless the approved Horizontal Subbase is used.

The required minimum clearances for furnace are specified in Table 1.

The furnace should be located as close as possible to chimney or vent in order to keep vent connections short and direct. The furnace should also be located as near as possible to center of air distribution system.

Step 2—Location Relative to Cooling Equipment

When installing furnace with cooling equipment for year-round operation, the following recommendations must be followed for series or parallel airflow:

1. In series airflow applications, coil is mounted after furnace in an enclosure in supply-air stream. The furnace blower is used for both heating and cooling airflow.

The coil MUST be installed on air discharge side of furnace. Under no circumstances should airflow be such that cooled, conditioned air can pass over furnace heat exchanger. This will cause condensation in heat exchanger and possible failure of heat exchanger which could lead to a fire hazard and/or a hazardous condition which may lead to bodily harm. Heat exchanger failure due to improper installation may not be covered by warranty.

2. In parallel airflow applications, dampers must be provided to direct air over furnace heat exchanger when heat is desired and over cooling coil when cooling is desired.

IMPORTANT: The dampers should be adequate to prevent cooled air from entering furnace. If manually operated, dampers must be equipped with a means to prevent operation of either cooling unit or furnace unless damper is in full cool or heat position.

INSTALLATION

Step 1—Air for Combustion and Ventilation

Installation of this furnace in an area where it will receive contaminated combustion air must be avoided. Such contamination would include the following: ammonia, chlorine, hydrogen sulfide, halogenated hydrocarbons, carbon tetrachloride, cleaning solvents, hydrochloric acid, water softening chemicals, and similar chemicals. Failure to follow this warning will lead to premature rusting of heat exchanger and possible premature furnace failure and/or vent failure which could result in fire hazard and/or bodily harm.

Do not block combustion-air openings in the furnace. Any blockage will result in improper combustion which may result in a fire hazard and/or cause bodily harm.

Step 2—General

This furnace should be installed in a location in which facilities for ventilation permit satisfactory combustion of oil, proper venting, and maintenance of ambient temperature at safe limits under normal conditions of use. The location should not interfere with proper circulation of air within the confined space. (See NFPA-31, Section 1.5.)

In addition to air needed for combustion, process air shall be provided as required for: cooling of equipment or material, controlling dew point, heating, drying, oxidation or dilution, safety exhaust, and odor control.

In addition to air needed for combustion, air shall be supplied for ventilation, including all air required for comfort and proper working conditions for personnel.

The barometric draft regulator (included with furnace) shall be installed in same room or enclosure as furnace in such a manner as to prevent any difference in pressure between regulator and combustion-air supply.

Air requirements for operation of exhaust fans, kitchen ventilation systems, clothes dryers, and fireplaces shall be considered in determining the adequacy of a space to provide combustion-air requirements.

The lack of a proper amount of combustion air can lead to serious furnace operational problems. Some of these problems are:

1. Excessive oil burner after-drip, and oil fumes.

2. Sooting.

3. Melted oil burner ignitor/relay control.

4. Air band or air turbulator settings more open than normal.

5. Lockouts on start-up.

The requirements for combustion and ventilation air depend upon whether furnace is located in a CONFINED or UNCONFINED space.

Step 3—Unconfined Space

An unconfined space must have at least 50 cu ft for each 1000 Btuh of total input for all the appliances (such as furnaces, clothes dryers, water heaters, etc.) in the space.

In unconfined spaces in buildings of conventional frame, brick, or stone construction, infiltration MAY be adequate to provide air for combustion, ventilation, and dilution of flue gases. This determination must be made on an individual installation basis and must take into consideration the overall volume of unconfined space, the number of windows and ventilation openings, the number of doors to the outside, internal doors which can close off unconfined space, and overall tightness of building construction. Consideration must also be given to the amount of storage items (furniture, boxes, etc.) within the unconfined space which take away from the air volume. (See Table 2.)

Many new buildings and homes (and older ones that have been weatherized) MUST BE considered as being of tight construction, therefore, infiltration will not be sufficient to supply necessary air for combustion and ventilation.

91,000 607 105,000 700 119,000 793 140,000 933 154,000 1026

A building can be considered as being of tight construction when:

• Walls and ceilings exposed to outside atmosphere have a continuous water vapor retarder with a rating of 1 perm or less with openings gasketed or sealed, and/or

• Weatherstripping has been added on operable windows and doors and/or

• Caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and fuel lines, and at other openings.

If combustion and ventilation air must be supplied to an unconfined space from outside, an opening with a FREE AREA of not less than 1 sq in. per 1000 Btuh of total input of all appliances within unconfined space (but not less than 100 sq in.) must be provided. This opening must be located such that it can not be blocked at any time.

Step 4—Confined Space

A confined space has a volume of less than 50 cu ft per 1000 Btuh of the total input rating for all appliances installed in that space.

When furnace is installed in a closet or enclosure, 2 ventilation openings, with OPEN AREA as dimensioned in example below are required for combustion air. The openings should be located about 6 in. from top and bottom of enclosure at front of furnace. (See Table 3.)

NOTE: In calculating free area, consideration shall be given to

blocking effect of louvers, grilles, or screens protecting openings. Screens used shall not be smaller than 1/4-in. mesh and shall be readily accessible for cleaning. If free area through a louver or grille is known, it shall be used in calculating size and free area specified. If design and free area are not known, it may be assumed that wood louvers have 20 percent free area and metal louvers and grilles have 60 percent free area. Louvers shall be fixed in open position or interlocked with furnace so they open automatically at furnace start-up and remain open during furnace operation.

The size of the openings depends upon whether the air comes from outside of the structure or an unconfined space inside the structure.
