4. Plug the thermostat into the jack on the Dragon.
The jack is located next to the HEAT and FAN
switches.
Plug the thermostat into the jack on the Dragon
Note:
The HEAT switch will not function and the
Dragon will not heat the air unless the thermostat
is plugged into the jack.
For more information about operating the remote
thermostat, see the section "Programming the
thermostat."
Establishing negative air pressure
Always create a negative air pressure in the affected
area when using the Dragon. An area has negative air
pressure when the air pressure inside is lower than
outside. This helps prevent odors and contaminants
from spreading to unaffected areas through cracks,
crevices, and openings in the structure walls.
On average, the Dragon will force in about 800 CFM.
As long as you remove more than 800 CFM through
an exhaust opening, more air will flow out of the
affected area than will flow in from the Dragon. This
differential creates the negative air pressure in the
affected area—a slight vacuum effect—so that any
contaminants and odors are exhausted harmlessly
outdoors instead of being forced into other areas of the
structure.
1. First close or block any large openings between
the affected area and other parts of the structure.
2. Select an opening between the affected area and
the outdoors to use as an exhaust, preferably on a
side opposite the Dragon process air. A window or
crawlspace vent hole will do.
3. Place a TurboDryer, Vortex Axial Fan, or other
airmover so that it forces air out of the affected
area to the outdoors through the selected opening.
The airmover should remove at least 800 CFM
from the affected area.
Starting the Dragon
Inspecting before operation
Warning!
Before starting the Dragon:
Check for any fuel leaks around the fuel tank or fuel
lines.
Check for nearby hazards like combustible
materials or flammable vapor sources.
Check the power cord for damage.
Correct these and any other safety hazards before
starting the Dragon.
Starting the Dragon
1. Check the fuel tank. If needed, add #2 diesel fuel
to
the fuel tank. Do not overfill.
WARNING!
Turn off
power and allow unit to cool before refueling.
2. With the ducting secured, the thermostat in place,
and negative air pressure established, plug the
Dragon’s power cord into a nearby outlet.
3. Turn the HEAT switch to on. This provides power
to the thermostat. The thermostat will only function
when the HEAT switch is on.
4. While the Dragon’s heat exchanger is warming up,
set the desired temperature on the thermostat
control box. See the next section, "Programming
the thermostat," for more information.
5. Monitor the settings on the Dragon and conditions
in the structure at least twice daily during
operation.
Programming the thermostat
The remote thermostat controls the operation of the
Dragon. Based on the settings you program, the
Dragon will cycle on and off to maintain a
predetermined temperature in the affected area. It can
be programmed in either degrees Fahrenheit or
Celsius.
