Goodman Mfg GPG13 installation manual Venting, Condensate Drain, Normal Sequences of Operation

VENTING

NOTE: Venting is self-contained. Do not modify or block.

FLUE HOOD INSTALLATION

Install the flue hood and bug screen prior to operation of the unit.

To install the flue hood cover and bug screen:

1.Remove the flue hood and bug screen from inside the heat exchanger compartment.

2.Slide the bug screen over the flanges of the flue hood and attach the flue hood and screen to the unit with the sheet metal screws provided.

CONDENSATE DRAIN

CONDENSATE DRAIN CONNECTION

A 3/4” NPT drain connection is supplied for condensate piping. An external trap must be installed for proper condensate drainage.

NORMAL SEQUENCES OF OPERATION

HEATING

This unit is equipped with an ignition control that automatically lights the main burner. DO NOT attempt to light the main burners by any other method.

1.Thermostat calls for heat. The induced draft blower energizes for a 15-second pre-purge.

2.The spark igniter and gas valve energizes for 7 seconds. NOTE: The igniter produces a very intense electrical spark that ignites the gas.

3.The 30-second HEAT FAN ON delay time begins. *PG13(48,60)***1A ONLY: Heat on delay begins when thermostat calls for heat. ECM motor is energized approximately 45 seconds later. NOTE: ECM motor may operate at approximately 100 CFM or less during the 45 second on delay period. ECM motor will energize at heating speed after the 45 second delay regardless of the status of the main burner flame.

4.The unit delivers heat to the conditioned space until the thermostat is satisfied.

5.The gas valve deenergizes. The induced draft blower continues operation for a 29-second post-purge.

6.Ignition control begins timing the HEAT FAN OFF delay. There is an adjustable HEAT FAN OFF delay of approximately 120/135/150 seconds (factory set at 150). After the HEAT FAN OFF delay time has elapsed, the blower will deenergize. This allows any additional heat in the heat exchanger to be transferred to the conditioned space. *PG13(48,60)***1A ONLY: HEAT FAN OFF delay is fixed at 180 seconds. Airflow level is 50% of nominal heating airflow.

COOLING

1.Thermostat calls for cooling. The compressor and outdoor fan are energized.

2.Approximately seven seconds later, the indoor fan starts.

3.The unit will deliver cooling to the conditioned space until the thermostat is satisfied.

4.The compressor and outdoor fan will be deenergized when the thermostat opens.

5.The indoor fan continues to run for approximately 60 seconds after the thermostat is satisfied. This allows

additional cooling from the indoor coil to be transferred to the conditioned space. Then, the indoor fan stops.

*PG1348***1A ONLY:

1.Thermostat calls for cooling. Outdoor fan and compressor are energized. ECM motor is energized almost immediately for 30 seconds at 50% of the nominal airflow. Airflow then increases to nominal airflow.

2.The unit will deliver cooling to the conditioned space until thermostat is statisfied.

3.The outdoor fan and compressor will be de-energized when thermostat opens.

4.ECM motor continues to operate for approximately 60 seconds at 50% of nominal airflow after thermostat opens.

*PG1360***1A ONLY:

1.Thermostat calls for low stage cooling. Outdoor fan and low stage compressor are energized. ECM motor is energized almost immediately for 30 seconds at 50% of the nominal low stage airflow. Airflow then increases to nominal low stage airflow.

If thermostat calls for high stage cooling, outdoor fan and low and high stage compressor is energized. ECM motor is energized almost immediately for 30 seconds at 50% of the nominal high stage airflow. Airflow then increases to nominal high stage airflow.

2.The unit will deliver cooling to the conditioned space until thermostat is satisfied.

3.The outdoor fan and low stage compressor (or low and high stage compressor) will be de-energized when thermostat opens.

4.ECM motor continues to operate for approximately 60 seconds at 50% of nominal low stage airflow (or high stage airflow if thermostat call was for high stage cooling) after thermostat opens.
