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.

1. When the Dragon is plugged in and the HEAT

switch is first turned on, the thermostat will display

the ambient temperature.

Before programming, the thermostat shows the current ambient temperature
