3 Maintenance

3.1 Air Filter

The Phoenix FireBird is equipped with a pleated fabric air filter that must be checked regularly. The standard filter is a MERV-11 high efficiency filter. Operating the FireBird with a dirty or obstructed filter will reduce airflow eventually causing the heating element to shut off. Installing a clean filter or removing the obstruction to restore airflow will allow the heating element to operate again.

The filter can generally be vacuumed clean several times before needing replacement. Replacement filters can be ordered from the factory or purchased locally if available.

WARNING: DO NOT operate the unit without the filter or with a less effective filter as the heating coils inside the unit could become clogged and require disassembly to clean.

4 Service

WARNING: Servicing the Phoenix FireBird with its high voltage circuitry presents a health hazard which could result in death, serious bodily injury, and/or property damage. Only qualified service people should service this unit.

Do not operate the unit without the front panel in place. High voltage is present, heater burnout may result.

4.1 Technical Description

The Phoenix FireBird uses a two stage wound nichrome heating element to provide two heat settings depending on application requirements or available power. One element provides low power operation and both elements together provide high power operation. The heating elements and the blower are operated by a 24VAC control circuit and a number of relays and contactors. For safety, there is an air pressure switch that will shut the heating elements off or prevent the heating elements from coming on if airflow is restricted at either the inlet or the outlet. An additional safety switch limits the incoming air temperature to 140°F. This switch shuts off the heating elements and automatically resets when the temperature falls to 100°F.

4.2 Troubleshooting

NOTE: High Power setting requires an external 50A circuit. Connecting to a 30A circuit with unit set to High Power will result in an external circuit breaker trip.

Blower not running

1.Unit unplugged, no power to outlet

2.Power switch not working or set to “THERMOSTAT” and no thermostat connected, or thermostat not calling for heat

3.Blower Relay not operating

4.Wiring fault inside device

5.Defective blower or blower capacitor

Blower running but no heat

1.Airflow restricted at inlet or outlet

2.High temperature limit reached (140°F)

3.Heating contactor(s) not operating

4.Wiring fault inside device

5.Defective heating element, pressure switch, or temperature limit switch
