TROUBLE SHOOTING

DIAGNOSTIC FEATURES

The control board is equipped with 4 green Input Status LEDs and 1 red Board Status LED. These are intended to provide a quick view into furnace performance without requiring a voltmeter.

The green Input Status LEDs are driven by the “Y”, “W”, “G”, and “DEHUM” inputs and are located directly below those inputs. They will light to indicate the presence of these signals.

The red Board Status LED has two functions:

It will light when the board recognizes a valid input signal and will stay lit until all valid signals are removed. This is intended to show that the board is functioning and able to respond to input signals.

It will flash rapidly while 120VAC is missing from the LIMIT switch. This is intended to give a quick visual indication of the High Limit switch.

N.STARTUP PROCEDURES:

A.Heating System

1.Initial Startup:

: Turn off power to furnace. Before the oil piping system is placed into service, it must have been leak tested by a qualified heating contractor.

: For initial start-up of the appliance after installation, it may be necessary to purge the air out of the oil line. A qualified heating contractor should do this.

Review the following items before the initial startup. It may be helpful to review the Sequence of Operations in Section VIII of this manual, also.

a.Check all wiring for loose connections and proper hook-up. Refer to the connection diagram.

b.Leak test all field oil piping connections. Generally, this will involve pressurizing the oil piping with air while being careful to isolate the oil tank at high test pressures. A qualified heating contractor should perform this service.

c.Check to see that the vent terminal is correctly installed and the terminal openings are clear and free from blockage.

d.Make sure the air filter is in place and relatively clean of dirt and debris.

e.Make sure the thermostat is set in the heating mode of operation.

For Your Safety Read Before Operating:

: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life.

•This appliance does not have a pilot light. It is equipped with an ignition system that automatically lights the burner. Do not attempt to light the burner by hand.
