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- 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
40°F. This switch shuts off the heating elements and
automatically resets when the temperature falls to 00°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.
