This is the safety-alert symbol (A). When you see this symbol on the unit and in instructions or manuals, be alert to the potential for personal injury. 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 injury or death. Warning indicates a condition that could result in personal injury. Caution is used to identify unsafe practices which would result in minor personal injury or product and property damage. 1. The power supply (v, ph and Hz) must correspond to that specified on unit rating plate. 2. The electrical supply provided by the utility must be sufficient to handle load imposed by this unit. 3. Refer to Locate the Unit section on page 2 and Fig. 2-4 for locations of gas inlet, electrical inlets, condensate drain, duct connections and required clearances before setting unit in place. 4. Locate the unit where the vent cap will be a minimum of 4 ft from openable windows or doors. 5. This installation must conform to local building codes and with the National Fuel Gas Code (NFGC), American National Standards Institute (ANSI) Z223.1-1988 (in Canada, CAN/CGA [Canadian Gas Association] B149.1, [2]-M86) or NFPA (National Fire Protection Association) 54-1988 TIA-54-84-1. Refer to Provincial and local plumbing or wastewater codes and other applicable local codes. 6. Approved for outdoor*!nstall^tion on wood flooring or on class A, B or C roof covering materials. INSTALLATION The small-cabinet units are shipped in the downflow configuration. To convert to horizontal discharge, refer to Field Duct Connections section on page 11. The large-cabinet units have discharge openings for both downflow and horizontal discharge and are factory shipped with duct opening covers in place. See Fig. 3 for small-cabinet unit sizes and Fig. 4 for large-cabinet unit sizes. Model 584B meets the California maximum oxides of nitrogen (NOx) emission regulations. These units are equipped with an energy-saving, automatic, electric, intermittent spark ignition system that does not have a continuously burning pilot. All units are manufactured with natural gas controls. These units are designed for a minimum continuous return-air temperature of 67 F (dry bulb). All units can be connected into existing duct systems that are sized properly and designed to handle an airflow of 350 to 450 cfm for each 12,000 Btuh of rated cooling capacity. NOTE: When installing any accessory item, see the manufacturer’s installation instructions packaged with the accessory. I. LOCATE THE UNIT A. Clearance Maintain clearance around and above unit to provide minimum distance from combustible materials, proper airflow and service access. See Fig. 2-4. The condenser fan discharges through the top of the unit. Ensure that the fan discharge does not recirculate to the condenser coil. Do not locate the unit either in a corner or under a complete overhead obstruction and ensure the following clearances are provided: On roof overhangs, provide a minimum clearance of 48 in. above the top of the unit for partial overhangs (such as a normal house roof overhang). If there is a horizontal extension on the partial overhang, it must not exceed 48 inches. Fig. 2 - Service and Operational Clearances Provide a minimum clearance of 42 in. for the control box side next to a block wall or any other grounded surface. Provide a minimum clearance of 48 in. between the control box side of the unit and any electrically live parts (for example, another unit). Provide ...
