2.1 Transporting
The Quest Power Electric Heat EHS 20 Pro must always be upright when transported by
vehicle. EHS 20 is equipped with rubber corners to permit stacking for storage. If units are
transported, they need to be secured with restraining straps to prevent damage and possible
injury.
2.2 Electrical Requirements
The Quest Power Electric Heat EHS 20 Pro requires a 120VAC outlet to power the onboard blower, control
and first heater circuit. Three additional heating elements are separately powered by additional cords and
receptacles.
120VAC heating elements each require cord connection to appropriate receptacles rated at 15A or more.
One cord and receptacle are required per heating element. Power cords should be appropriately sized
(typically #12 minimum). Each heater cord should have a three-blade grounding-type plug as shown. An
adapter is available for connecting to two-slot receptacles. The green grounding lug extending from the
adapter must be connected to a permanent ground such as a properly grounded outlet box. The adapter
should not be used if a three-slot grounded receptacle is available.

2.3 Ducting
The Quest Power Electric Heat EHS 20 Pro can be ducted at the inlet, the outlet or both. The Power Electric
Heat EHS 20 Pro inlet and outlet duct are designed to accommodate 8” flexible duct. When selecting
flexible ducting keep in mind anticipated outlet temperatures. Air temperature increase is typically 50
to 80 degrees F. Adding ducting decreases airflow which can increase outlet temperatures by up to 40
additional degrees F.
NOTE: It is strongly discouraged to use Mylar ducting as this could burn and cause a fire.
2.4 Control Panel
Fan Mode Switch: This switch allows the user to operate in ‘FAN ON’ or ‘FAN AUTO’ mode. In ‘FAN ON’
mode, the blower will remain on whenever the unit is energized. This mode is recommended for normal
operation where constant air circulation is desired. In ‘FAN AUTO’ mode, the blower will only energize
when there is a demand for heat from the remote thermostat connection. To use this mode, the CONTROL
POWER switch must be set to ‘THERMOSTAT CONTROLLED.’ This mode is recommended for applications
that do not require constant air circulation during heating.
Control Power Switch: The CONTROL POWER switch performs two functions. It controls the master power
to the Compact 20, and it allows the user to select from an internal or external thermostat. In ‘ALWAYS
ON’ mode, the Compact 20 uses an internal thermostat preset at 140F. Heat will continue to be produced
until the air flowing into the inlet reaches 140F. In ‘THERMOSTAT CONTROLLED’ mode, the Compact 20
looks for a closed circuit at the THERMOSTAT connection on the front of the control panel. Any dry contact
switch or the included remote thermostat with 25’ of wire can perform this function.
Start/Reset Switch: The START/RESET Switch is used to enable the Compact 20 to produce heat. If at any
time power to the control circuit is lost or if a fault condition occurs, the Compact 20 will go into the
FAULT/NOT RUNNING mode. Pushing the START/RESET switch will energize the control circuit and restart
the Compact 20.

Quest Power Electric Heat EHS 20 Pro
Installation, Operation and Maintenance Instructions
OK/Running Lamp: The OK/RUNNING lamp will illuminate when the control circuit is energized. If the
lamp is lit, the Compact 20 is under the control of either the internal or external thermostat (depending
on which thermostat is selected with the control power switch). In this state, the heater will be on until it
reaches cycling temperatures (130F-140F) and will then self-regulate at this range.
FAULT/NOT RUNNING Lamp: If the FAULT/NOT RUNNING lamp is lit, the contactor control circuit is
not energized, which will disable the heater circuits and no heat will be produced.
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.
Heat ON/OFF Switches: These switches individually control the heating elements. Each switch connects
and disconnects the power from the receptacle next to it. These switches are lighted to indicate when
power is connected and the corresponding heating element is on.
Remote Thermostat Connection: There are two spring loaded terminals for connecting the thermostat
wiring on the control panel. Connect one wire to each terminal. For applications where the FireBird
Compact 20 is placed outside the space to be heated (e.g. ducting heat into a chamber), the 25’ cord
allows you to place the thermostat inside the heated space.
In addition to the included thermostat, any dry-contact switch or other type of control that connects the
terminals together will cause the heating elements to run. The thermostat circuit is low voltage (24VAC).
DO NOT CONNECT POWER TO THE THERMOSTAT TERMINALS.
Control Power Switch: The Master Power Switch located on the center-top of the control panel 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 Compact 20 will energize the blower and close the heater contactors continuously.
Depending on the connected power sources, the corresponding heater elements will be energized. In this
mode, the Compact 20 is limited to 140°F incoming air temperature by an internal thermostat.
When set to THERMOSTAT, the blower will run continuously, but the heating contactors will only
energize when the thermostat terminals (located on the lower right of the control panel) are connected by
a switch, remote thermostat, timer, etc.
3 Maintenance
3.1 Air Filter
The Quest Power Electric Heat EHS 20 Pro 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 Power Electric
Heat EHS 20 Pro 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.

Installation, Operation and Maintenance Instructions
4 Service
WARNING: Servicing the Quest Power Electric Heat EHS 20 Pro 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 cover in place. High voltage is present, heater burnout may
result.
4.1 Technical Description
The Quest Power Electric Heat EHS 20 Pro uses a wound nichrome heating element to provide multiple
heat settings depending on application requirements or available power. The heating elements 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 approxmiately 140°F. This switch shuts off the heating elements and automatically resets when the
temperature falls to approximately 130°F.
4.2 Troubleshooting
Low voltage heating circuits require dedicated 15A minimum service for each circuit (up to 4 total).
Blower not running
1. Unit unplugged, no power to outlet
2. Control Switch not working
3. Wiring fault inside device
4. Defective blower or blower capacitor
Blower running but no heat when Ok/Running lamp is on
1. Power switch is set to “Thermostat” and no thermostat is connected, or thermostat is open
2. High temperature limit reached (140°F)
3. Heating relays not operating
4. Wiring fault inside device
5. Defective heating element, pressure switch, or temperature limit switch
Fault/Not Running lamp illuminated
1. Press Start/Reset button
2. Reduce the length of inlet or outlet duct (if ducted)
3. Check duct for kinks or sharp bends in inlet or outlet (if ducted)
4. Impeller is obstructed or slow
5. Voltage is low
6. Create openings in heated cavities to reduce backpressure.
