Installation, Operation and Service Instructions
Important Instructions – Read and Save These Instructions
The FireBird portable, heavy duty electric heater features a built-in 50-amp twist lock receptacle designed to work with
standard 30 or 50 amp power sources—select the setting using the HIGH/LOW switch.
At the 50-amp setting, the FirebBird produces 3ꢀ,000 BTU’s—thats 360 CFM with a 80°F temperature rise. In an area
with below freezing temperatures the FireBird can produce 360 CFM of air over ꢀ00 degrees. Using the 30-amp setting the
FireBird produces ꢀ8,000 BTU’s—giving a 46°F temperature rise. Internal temperature cutouts prevent the FireBird from
overheating an area while the FireBird’s externally located thermostat terminals provide a means to control the heat from
anywhere in the drying space.

Master POWER Switch: The master power switch located
on the back of the FireBird can be used to turn the unit
ON, OFF, or set the unit to be controlled by an external
thermostat.
When set to ON, the FireBird will energize the blower
relay and heater elements(s) continuously. In this mode,
the heaters are thermostatically limited to ꢀ40 degree F
incoming air temperature with an automatic switch.
2 Operation
2.1 Transporting
The Phoenix FireBird must always be upright when
transported by vehicle. It may be tipped onto its handle
and back for loading and moving by hand. The Phoenix
FireBird features a high-impact plastic skid plate which
protects the unit while navigating obstacles such as curbs,
stairways, and while loading into vehicles.
When set to THERMOSTAT, the blower and heater will run
when the thermostat terminals (located under the lid) are
connected by a switch, remote thermostat, timer, etc.
HIGH/LOW POWER Switch: This switch selects either
high or low power operation. If this switch is set to HIGH
POWER operation, the FireBird MUST be connected to a
minimum 50 Amp source.
2.2 Electrical Requirements
The Phoenix FireBird requires 220/240VAC. The FireBird
outlet is 240VAC with ground. When properly installed,
it provides a ground connection through the cord to the
heater to protect the operator from electric shock. The
Phoenix FireBird comes equipped with two 8’ long cords
for connection to grounded residential range and dryer
receptacles. An accessory extension cord is also available
(see Accessories).
2.5 Hour Meter
The digital hour meter measures the cumulative time that
the unit is turned on to tenths of an hour. It stores and
displays the total when the unit is unplugged. It resets to
zero after 99,999.9 hours of operation.
2.6 Remote Thermostat Connection
To connect a remote thermostat, switch, or timer control,
first locate the thermostat terminals under the lid of
the FireBird. There are 2 spring loaded terminals for
connecting thermostat wiring. Any dry-contact switch,
thermostat, or other type of control that connects the
terminals together will cause the heater to run. The
thermostat circuit is low voltage (24VAC). DO NOT
CONNECT POWER TO THE THERMOSTAT TERMINALS.
2.3 Ducting
The Phoenix FireBird can be ducted at the inlet, the
outlet or both using the included round outlet adapter.
The FireBird lid and outlet adapter are designed to
accommodate ꢀ2” flexible duct. When selecting flexible
ducting keep in mind anticipated outlet temperatures. Air
temperature increase is typically 50 to 80 degrees F for
low and high power settings respectively. Adding ducting
decreases airflow which can increase outlet temperatures
by up to 20 additional degrees F.
Always press terminal levers to release spring pressure
before disconnecting thermostat wiring. Failure to do
so will lead to excessive wear on spring loaded terminal
connector.

Blower not running
3 Maintenance
ꢀ. Unit unplugged, no power to outlet
3.1 Air Filter
2. Power switch not working or set to “THERMOSTAT” and
no thermostat connected, or thermostat not calling for
heat
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.
3. Blower Relay not operating
4. Wiring fault inside device
5. Defective blower or blower capacitor
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.
Blower running but no heat
ꢀ. Airflow restricted at inlet or outlet
2. High temperature limit reached (ꢀ40°F)
3. Heating contactor(s) not operating
4. Wiring fault inside device
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.
5. Defective heating element, pressure switch, or
temperature limit switch

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.

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.
