INSTALLATION INSTRUCTION
GENERAL
YORK Model DEG units are single package air conditioners with
gas heat designed for outdoor installation on a rooftop or a slab.
The units are completely assembled on rigid, permanently
attached base rails. All piping, refrigerant charge, and
electrical wiring is factory-installed and tested. The units
require only electric power, gas piping and duct connections
at the point of installation.
The gas-fired heaters have aluminized steel tubular heat
exchangers and spark ignition with intermittent pilot.
This appliance is not to be used for temporary heating of
buildings or structures under construction.
INSPECTION
As soon as a unit is received, it should be inspected for possible
damage during transit. If damage is evident, the extent of the
damage should be noted on the carrier's freight bill. A separate
request for inspection by the carrier's agent should be made in
writing. Refer to Form 50.15-NM for additional information.

Page 4: Ductwork 3
The supply and return air duct systems should be designed for the CFM and static requirements of the job. They should NOT be sized to match the dimensions of the duct connections on the unit. CAUTION: When fastening ductwork to the side duct flanges on the unit, insert the screws through the duct flanges only. -

NOTE: Install filters so that “Air Flow” arrows point toward the unit. 8. Install filter cover over the end of the hood with one screw (center of hood), securing filters into position. CAUTION: When proceeding with Steps 9 and 10, extreme care must be exercised while turning both the set point and minimum position adjusting screws to prevent twisting them off. -

035-14832-003-A-0204 TABLE 8 - STATIC RESISTANCES DESCRIPTION 1, 2 Economizer Bottom Duct Connections Deduct these resistance values from the available external static pressure shown in the respective Blower Performance Table. The pressure thru the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return air duct system is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation. -

Page 13: Operation
035-14832-003-A-0204 COOLING SYSTEM The cooling section is a complete factory package utilizing an air-cooled condenser. The system is factory-charged with Refrigerant-22. The compressor is hermetically sealed and internally sprung. The compressors have inherent (internal) protection. If there is an abnormal temperature rise in the compressor, the protector will open to shut down the compressor. -
Page 14: Safety Controls (Heating)
SAFETY CONTROLS (Heating) The control circuit includes the following safety controls: 1. Limit Control (LS). This control is located inside the heat exchanger compartment and is set to open at the temperature indicated in Table 12. It resets automatically. The limit switch, operates when a high temperature condition, caused by inadequate supply air flow occurs, thus shutting down the ignition control and closing the main gas valve. -
Page 15: Pilot Checkout
035-14832-003-A-0204 PILOT CHECKOUT The pilot flame should envelope 3/8 inches of the end of the flame sensor. Refer to Figure 12. To adjust pilot flame, (1) remove pilot adjustment cover screw, (2) adjust the screw for the proper pilot flame, (3) be sure to replace cover screw after adjustment to prevent possible gas leakage. -
Page 16: Checking Gas Input
NOTE: The tubes must be inserted and held in a position per- pendicular to the air flow so that velocity pressure will not affect the static pressure readings. 3. Using an inclined manometer, determine the pressure drop across a dry evaporator coil. Since the moisture on an evaporator coil may vary greatly, measuring the pressure drop across a wet coil under field conditions would be inac- curate. -
Page 17: Normal Maintenance
035-14832-003-A-0204 NORMAL MAINTENANCE CAUTION: Prior to any of the following maintenance proce- dures, shut off all power to the unit to prevent per- sonal injury. Periodic maintenance normally consists of changing or cleaning filters and (under some conditions) cleaning the main burners. FILTERS - Inspect once a month. -
Page 18: Troubleshooting
WARNING: Troubleshooting of components necessarily re- quires opening the electrical control box with the power connected to the unit. Use extreme care when working with live circuits! Check the unit nameplate for the correct line voltage and set the volt meter to the correct range before making any connections with line terminals. - Page 19 035-14832-003-A-0204 TROUBLESHOOTING - Continued. 6. The pilot burner ignites but the sparker continues to spark and the main burners do not ignite. a. Make the same checks and adjustments as described in Item 5. b.Make sure that the pilot burner is not bent or damaged. c.
