Introduction
The Dragon X2 Mobile Furnace is an indirect fired
heater. This design keeps combustion air separate from
heated air and allows the Dragon to heat air without
adding any moisture, fumes or smoke.
The Dragon should always be operated outdoors, and
should utilize outside air for combustion. An electric fan
directs this heated air into the structure through ducting.
The remote thermostat automatically cycles the Dragon
on and off to maintain a preset temperature in the target
area.
Principles of Use
The clean, dry heat from the Dragon helps reduce drying
times while maintaining stable and comfortable
temperatures. The Dragon is ideal for wide range of
applications, including
• water damage restoration
• new construction drying
• unheated jobsites
• temporary event shelters
• workshops, storage rooms, and warehouses
• greenhouses and polyurethane tunnels for
agriculture
• any situation calling for clean, dry temporary heat
For use in water damage restoration and new
construction drying, the Dragon can increase drying
efficiency. The added heat from the Dragon will increase
the rate of evaporation by decreasing the relative
humidity of the affected area. Raising the temperature of
a drying area with the Dragon from 60° to 70°F can
increase the evaporative potential of your existing drying
system up to 45 percent.
For best results when using the Dragon for restoration,
you should understand the basic principles of structural
drying. You can learn these skills and more in an IICRC-
certified Applied Structural Drying (ASD) course. To
learn more about ASD courses, contact the Dri-Eaz
Education Department at 800-932-3030.
Electrical requirements
The Dragon X2 Mobile Furnace is designed to
operate on a 115V/60 Hz electrical connection. The unit
requires 10 amps. Make sure that the electrical outlet is
grounded with three prongs. When using with an
extension cord, use only a grounded cord intended for
outdoor use and rated to deliver enough power to the
Dragon.

Fuel type
The Dragon X2 Mobile Furnace can operate for approxi-
mately 72 hours on a single tank, depending on
conditions.The Dragon is designed to operate on no. 1
or no. 2 diesel or fuel oil. In cold weather, you may add
kerosene to the diesel as described under "Cold
temperature recommendations," below.
WARNING: Failure to use diesel fuel or a diesel-
kerosene mixture as specified could cause injury
and permanent damage to the unit. It may also void
the Dri-Eaz warranty.
For best results, purchase fresh fuel from a reliable fuel
oil distributor. Keep the Dragon fuel tank full to help
prevent the formation of condensation inside the tank.
When not using the Dragon for extended periods of time,
consider the addition of a diesel fuel stabilizer to the fuel,
available at most automobile parts stores.
Cold temperature recommendations
In temperatures below 23°F (−5°C), diesel tends to
thicken and may block the fuel filters. To improve fuel
flow characteristics in cold temperatures, a mixture
containing up to 15% kerosene may be used. The
Dragon may be operated with higher percentages of
kerosene up to 100% kerosene, but this requires special
adjustments. Contact Dri-Eaz Service at 800-932-3030
for instructions.
In normal operating conditions (above 30° F or 0° C), the
rain shield should be removed when operating the
Dragon. However, when operating the Dragon in
extremely low outdoor temperatures (below 30° F or
0° C) the temperature of the outlet air can be increased
by leaving the rain shield in place during operation. Note
that this configuration restricts airflow and will reduce the
Dragon's CFM output.
To adjust for proper combustion and for use at high
altitudes, see "Adjusting for Altitude," p. 4.
Trailer Safety
Do not exceed the rated towing or tongue weight
capacity of your vehicle. To prevent unexpected
movement and possible damage and injury, always
chock the wheels securely when parking the trailer.
Perform a trailer safety inspection before each trip. Make
sure that
• The ball mount is properly inserted into the receiver
and the safety pin installed.
• The hitch coupler is locked in place and the safety
pin is installed.
• Safety chains are properly attached.
• The electrical plug is properly installed.
• Trailer tires are properly inflated.
