Introduction
The Dragon 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. An electric fan directs 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 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 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 a three
prong type grounded outlet. When using with an
extension cord, use only a grounded cord intended for
outdoor use and rated to deliver enough power to the
Dragon.
Run time and fuel type
The Dragon Mobile Furnace can operate for approxi-
mately 13.5 hours on the built-in tank, depending on
conditions. Use of the the external fuel pickup can
extend continuous operation up to 72 hours.
NOTE: The fuel lines must be adapted for use with the
external fuel pickup. See “Modifiying the Dragon for use
with the Fuel Pickup,” p. 7, for instructions.
The Dragon is designed to operate on no. 2 diesel. 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 may require special
adjustments. Contact Dri-Eaz Service at 800-932-3030
for instructions.
To adjust for proper combustion and for use at high
altitudes, see “Adjusting for Altitude,” p. 5.
