264973-YIM-A-0806 This product must be installed in strict compliance with the enclosed installation instructions and any applicable local, state and national codes including, but not limited to, building, electrical, and mechanical codes. The furnace and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing at pressures in excess of 1/2 PSIG. Pressures greater than 1/2 PSIG will cause gas valve damage resulting in a hazardous condition.

264973-YIM-A-0806 DUCTWORK DUCT COVERS Ductwork should be designed and sized according to the methods in Manual D of the Air Conditioning Contractors of America (ACCA) or as recommended by any other recognized authority such as ASHRAE or SMACNA. Units are shipped with the side duct openings covered and a covering over the bottom of the unit. For bottom duct application, no duct cover changes are necessary. For side duct application, remove the side duct covers and install over the bottom duct openings.

264973-YIM-A-0806 CONDENSATE DRAIN When fastening ductwork to side duct flanges on unit, insert screws through duct flanges only. DO NOT insert screws through casing. Outdoor ductwork must be insulated and water-proofed. The side condensate drain is reversible and maybe re-oriented to the rear of the cabinet to facilitate condensate piping. A condensate drain connection is available through the base pan for piping inside the roof curb. Trap the connection per Figure 16.

264973-YIM-A-0806 OPTIONAL ELECTRIC HEAT GAS PIPING The factory-installed heaters are wired for single point power supply. Power supply need only be brought into the single point terminal block. Proper sizing of gas piping depends on the cubic feet per hour of gas flow required, specific gravity of the gas and the length of run. "National Fuel Gas Code" Z223.1 (in U.S.A.) or the current Gas Installation Codes CSA-B149.
PAGE 32
264973-YIM-A-0806 TABLE 33: GAS PIPE SIZING - CAPACITY OF PIPE 4. All piping should be cleaned of dirt and scale by hammering on the outside of the pipe and blowing out loose particles. Before initial start-up, be sure that all gas lines external to the unit have been purged of air. 5. The gas supply should be a separate line and installed in accordance with all safety codes as prescribed under “Limitations”. 6.

264973-YIM-A-0806 LP UNITS, TANKS AND PIPING All gas heat units are shipped from the factory equipped for natural gas use only. The unit may be converted in the field for use with LP gas with accessory kit model number 1NP0442. All LP gas equipment must conform to the safety standards of the National Fire Protection Association. For satisfactory operation, LP gas pressure must be 10.5 inch W.C. at the unit under full load. Maintaining proper gas pressure depends on three main factors: 1.

264973-YIM-A-0806 PHASING A Predator® units are properly phased at the factory. Check for proper compressor rotation. If the blower or compressors rotate in the wrong direction at start-up, the electrical connection to the unit is misphased. Change the phasing of the Field Line Connection at the factory or field supplied disconnect to obtain proper rotation. (Scroll compressors operate in only one direction.

264973-YIM-A-0806 NOTES FOR TABLE 35 THROUGH TABLE 58: • • Blower performance includes dry coil and two-inch filters. Blower performance for gas heat includes the maximum number of heat tubes available for each tonnage. • ESP (External Static Pressure) given is that available for the supply and return air duct system. All internal resistances have been deducted from the total static pressure of the blower.

264973-YIM-A-0806 AIR BALANCE Start the supply air blower motor. Adjust the resistances in both the supply and the return air duct systems to balance the air distribution throughout the conditioned space. The job specifications may require that this balancing be done by someone other than the equipment installer. CHECKING AIR QUANTITY METHOD ONE 1. Remove the dot plugs from the duct panel (for location of the dot plugs see Figure 10). 2.

264973-YIM-A-0806 SUPPLY AIR DRIVE ADJUSTMENT EXAMPLE A 12.5 ton unit was selected to deliver 4,000 CFM with a 3 HP motor, but the unit is delivering 3,800 CFM. The variable pitch motor sheave is set at 2 turns open. Before making any blower speed changes review the installation for any installation errors, leaks or undesirable systems effects that can result in loss of airflow. Even small changes in blower speed can result in substantial changes in static pressure and BHP.

If the unit fails after five recycle attempts, the furnace is locked-out for one hour. GAS HEATING OPERATION ERRORS LOCK-OUT A one-hour lockout occurs following three retries or five recycles. During the one-hour lockout, flame detection, limit conditions, and main valves are tested. Any improper results will cause the appropriate action to occur.

264973-YIM-A-0806 POST START CHECK LIST 1. Verify proper system pressures for both circuits. 2. Measure the temperature drop across the evaporator coil. 2. Check for correct manifold gas pressures. (See ’CHECKING GAS INPUT’.) 3. Check the supply gas pressure. It must be within the limits shown on the rating nameplate. Supply pressure should be checked with all gas appliances in the building at full fire. At no time should the standby gas pressure exceed 10.5 in.

Even when the thermostat is calling for first stage heat, the unit will light on second stage and will run on Second stage for 1 minute. Allow this one-minute time period to expire and be certain the unit is running on first stage. 4. NOTE: When using natural gas, the manifold pressure for second stage (100% input) should be 3.

264973-YIM-A-0806 EXAMPLE: By actual measurement, it takes 19 seconds for the hand on a 1 cubic foot dial to make a revolution with a 192,000 Btuh furnace running. To determine rotations per minute, divide 60 by 19 = 3.16. To calculate rotations per hour, multiply 3.16 • 60 = 189.6. Multiply 189.6 • 1 (0.5 if using a 1/2 cubic foot dial) = 189.6. Multiply 189.6 • (the Btu rating of the gas). For this example, assume the gas has a Btu rating of 1050 Btu/ft.3.

The UCB will flash the last five alarms on the LED. If the compressor is locked out, cancel any call for cooling. This will reset any compressor lock outs. NOTE: While the above step will reset any lockouts, compressor #1 may be held off for the ASCD. See the next step. 10.

Check for 24 volts at the HPS2, LPS2, and FS2 terminals of the UCB. If a switch has opened, there should be a voltage potential between the UCB terminals, e.g. if LPS2 has opened, there will be 24 volts of potential between the LPS2 terminals.

If 24 volts is present at the UCB Y1 terminal and the compressor is not out due to a protective switch trip, repeat trip lock out, or ASCD, the economizer terminals of the UCB may be improperly wired. Check for 24 volts at the Y1 “OUT” terminal of the UCB. If 24 volts is present, trace the wiring from Y1 “OUT” for incorrect wiring. If 24 volts is not present at the Y1 “OUT” terminal, the UCB must be replaced. 12.

If the blower motor runs with the fan switch in the “ON” position but does not run shortly after the furnace has ignited when the fan switch is in the “AUTO” position, check the room thermostat for contact between R and G during “W1” calls. On calls for heating, the supply air blower operates but the draft motor does not (the room thermostat fan switch is in the “AUTO” position). 1. The draft motor has inherent protection.
