66324-YIM-B-1004 RIGGING OR HANDLING CLEARANCES Care must be exercised when moving the unit. Do not remove any packaging until the unit is near the place of installation. Rig unit with slings placed under the unit. Spreader bars of sufficient length should be used across the top of the unit. All units require certain clearances for proper operation and service. Refer to Figure 5 for the clearances required for combustion, construction, servicing and proper unit operation.

6324-YIM-B-1004 ROOF CURB On applications when a roof curb is used, the unit must be positioned on the curb so the front of the unit is tight against the curb. FILTERS Single phase units are shipped without a filter or filter racks and is the responsibility of the installer to secure a filter in the return air ductwork or install a Filter/Frame Kit (1FF0110). A filter rack and a high velocity filters are standard on three phase units. Filters must always be used and must be kept clean.

Before initial start-up, be sure that all of the 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. After the gas connections have been completed, open the main shut-off valve admitting normal gas pressure to the mains.

66324-YIM-B-1004 SEQUENCE OF OPERATION CIRCULATING FAN The unit is controlled by a conventional four wire heating/ cooling thermostat common to this class of equipment. When the thermostat calls for FAN, the thermostat terminal G is energized signaling the circulating fan to run at the heat speed 2 seconds after the G terminal is energized. HEATING When the thermostat calls for HEAT, the thermostat terminal W is energized, energizing the combustion air blower.

L IN E P R E S S U R E T A P POST-START CHECK LIST (GAS) After the entire control circuit has been energized and the heating section is operating, make the following checks: 1. Check for gas leaks in the unit piping as well as the supply piping. 2. Check for correct manifold gas pressures. See Checking Gas Input. 3.

66324-YIM-B-1004 HOT SURFACE PILOT INSTRUCTIONS 2. To check, adjust or remove the hot surface pilot assembly, CLOSE THE MAIN MANUAL SHUT-OFF VALVE AND SHUT OFF ALL POWER TO THE UNIT. ADJUSTMENT OF TEMPERATURE RISE The pilot flame should envelope 1/2 inch of the end of the flame sensor and not contain any yellow color, see Figure 7. Lift the pilot and sensor from the assembly. Care must be taken not to damage the pilot or sensor when removing this assembly.

66324-YIM-B-1004 NOTE: To find the BTU input, multiply the number of cubic feet of gas consumed per hour by the BTU content of the gas in your particular locality. (Contact your gas company for this information since it varies widely from city to city.) TABLE 11: GASE RATE - CUBIC FEET PER HOUR1 SECURE OWNER'S APPROVAL When the system is functioning properly, secure the owner's approval. Show him the location of all disconnect switches and the thermostat.

At the beginning of each heating season, make a visual check of the main burner flame. If it is not possible to adjust for the proper flame, the burners may need cleaning. 7. Replace parts in the order they were removed in steps 1 through 3. TO CLEAN BURNERS Remove them from the furnace as explained in Burner Instructions. Clean burners with hot water applied along top of the burner.
