A U Tube manometer having a scale range from 0 to inches of water should be used for this measurement. The manifold pressure must be measured with the burners operating. To adjust the pressure regulator, remove the adjustment screw or cover on the gas valve. Turn out (counterclockwise) to decrease pressure, turn in (clockwise) to increase pressure. Only small variations in gas flow should be made by means of the pressure regulator adjustment. In no case should the final manifold pressure vary more than plus or minus 0. inches water column from the specified nominal pressure. Any major changes in flow should be made by changing the size of the burner orifices. The measured input rate to the furnace must not exceed the rating specified on the unit rating plate. or natural gas, the manifold pressure must be between. and.8 inches water column (.5 nominal). or propane gas, the manifold pressure must be between 9.7 and 0. inches water column (0.0 nominal). as Input (Natural as Only) heck To measure the gas input use a gas meter and proceed as follows:. Turn off gas supply to all other appliances except the unit.. ith the unit operating, time the smallest dial on the meter for one complete revolution.

Thermometers must not be able to sample temperature directly from the unit heat exchangers, or false readings could be obtained.. All registers must be open; all duct dampers must be in their final (fully or partially open) position and the unit operated for 5 minutes before taking readings.. The temperature rise must be within the range specified on the rating plate. NOTE: Air temperature rise is the temperature difference between supply and return air. ith a properly designed system, the proper amount of temperature rise will normally be obtained when the unit is operated at rated input with the recommended blower speed. If the correct amount of temperature rise is not obtained, it may be necessary to change the blower speed. A higher blower speed will lower the temperature rise. A slower blower speed will increase the temperature rise. NOTE: lower speed MUST be set to give the correct air temperature rise through the unit as marked on the rating plate.

NOTE: Heating airflow must be adjusted to provide the temperature rise shown on rating plate. *P0***A ONL: Low stage airflow is approximately 75% of high stage cooling airflow. Example: High stage cooling airflow is 800 M. Low stage cooling airflow is 0.75*800 M = 50 M. The adjustment factors for the ADJUST function are A =, =.0 (+0%) and = 0.85 (-5%). The D tap for the ADJUST function has no effect on airflow. Example: Airflow tables indicate 5 M. ith the ADJUST set to tap, the M becomes.0*5 M = 58 M. Dehumidification The E EM motor has the capability to provide increased dehumidification during cooling operation. This is accomplished by lowering the airflow to approximately 85% of the nominal cooling airflow. Example: Unit is operating at 00 M and humidistat calls for dehumidification. esulting airflow is 0.85* 00 M = 90 M. To make use of this feature, a VA humidistat which opens on humidity rise is required. onnect humidistat to the HUMIDISTAT/HUM terminal on the low voltage terminal board (see wiring diagram in the appendix). lip the HUM/ PJ jumper on the low voltage terminal board.

ANOMAL OPEATION - HEATIN Internal ontrol ailure If the integrated ignition control in this unit encounters an internal fault, it will go into a hard lockout and turn off the diagnostic LED. If diagnostic LED indicates an internal fault, check power supply to unit for proper voltage, check all fuses, circuit breakers and wiring. Disconnect electric power for five seconds. If LED remains off after restoring power, replace control. External Lockout An external lockout occurs if the integrated ignition control determines that a measurable combustion cannot be established within three () consecutive ignition attempts. If flame is not established within the seven (7) second trial for ignition, the gas valve is deenergized, 5 second inter-purge cycle is completed, and ignition is reattempted. The control will repeat this routine three times if a measurable combustion is not established. The control will then shut off the induced draft blower and go into a lockout state. If flame is established but lost, the control will energize the circulator blower at the heat speed and then begin a new ignition sequence. If flame is established then lost on subsequent attempts, the control will recycle for four () consecutive ignition attempts (five attempts total) before locking out. 5
