282911-YIM-A-0207 GENERAL APPROVALS YORK Model DNH units are cooling/heating air conditioners designed for outdoor installation. Only gas piping, electric power and duct connections are required at the point of installation. Design certified by CGA and AGA listed as follows: 1. For use as a forced air furnace with cooling unit. 2. For outdoor installation only. The gas-fired heaters have spark to pilot ignition. The tubular heat exchangers are aluminized steel. 3.
282911-YIM-A-0207 INSTALLATION LIMITATIONS Excessive exposure of this furnace to contaminated combustion air may result in equipment damage or personal injury. Typical contaminants include: permanent wave solution, chlorinated wastes and cleaners, chlorine based swimming pool chemicals, water softening chemicals, carbon tetrachloride, halogen type refrigerants, cleaning solvents (e.g.

282911-YIM-A-0207 GAS PIPING TABLE 5: NATURAL GAS PIPE SIZING CHART1 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 National Fuel Gas Code Z223.1 or CAN/CGA B149.1 or .2 should be followed in all cases unless superseded by local codes or gas company requirements. Refer to Tables 5 and 6.
282911-YIM-A-0207 FLUE VENT HOOD If flexible stainless steel tubing is allowed by the authority having jurisdiction, wrought iron or steel pipe must be installed at the gas valve and extend a minimum of two (2) inches outside of the unit casing. The flue vent hood with screen is not shipped attached. This hood must be installed to assure proper unit operation.

282911-YIM-A-0207 SEQUENCE OF OPERATION The unit is controlled by a conventional heating/cooling thermostat common to this class of equipment. If the pressure switch is lost during an ignition trial period, the control immediately de-energizes spark and gas. The control begins pressure switch proving before an inter-purge and reignition attempt. HEATING PILOT FLAME STABILIZATION PERIOD The control board begins a call for heat when W1 is energized (connected to R).
282911-YIM-A-0207 High heat If the W2 terminal was energized more than 1 second before W1 at the start of the call for heat, and remains continuously energized through the call for heat, the control considers it to be connected to a single stage thermostat and implements a 10 minute Auto staging feature. The 2nd stage thermostat call is ignored until 10 minutes into steady heat (9 minutes after high heat warm-up ended).
282911-YIM-A-0207 of the unit wiring diagram. 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 and energizing the blower. After a cool fan off delay timing of 30 seconds the circulating fan is de-energized. CIRCULATING FAN When the thermostat calls for FAN, the thermostat terminal G is energized signaling the circulating fan to run at the cool speed. 2.
282911-YIM-A-0207 2. Turn off all electric power to the appliance if service is to be performed. 3. Remove the control access panel. 4. Turn the gas valve switch to the OFF position. DO NOT FORCE. 5. Replace the control access panel. POST-START CHECK LIST (GAS) After the entire control circuit has been energized and the heating section is operating, make the following checks: 1. Line Pressure Tap ½ NPT Check for gas leaks in the unit piping as well as the supply piping. (Inlet) 2.
282911-YIM-A-0207 The temperature rise (or temperature difference between the return air and the heated air from the furnace) must lie within the range shown on the rating plate and the data in Tables 3 and 4. 3 8" min. After the temperature rise has been determined, the CFM can be calculated as follows: After about 20 minutes of operation, determine the furnace temperature rise.
