Safety Information
Read this Owner's Manual carefully to learn how to
properly operate and service your Dragon K85 Mobile
Furnace. This manual should be considered a
permanent part of the machine and should remain
with the Dragon if you sell it.
Failure to comply with the instructions and precautions
provided in this Owner’s Manual can result in death,
serious bodily injury, and/or property loss or damage
from hazards of fire, explosion, burn, asphyxiation,
carbon monoxide poisoning, and/or electrical shock.
Electrical Connections
The Dragon K85 Mobile Furnace is designed to
operate on a 115V/60 Hz electrical connection. 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 (4.4 amps@115V
or 506W).
Fuel Type
The Dragon K85 Mobile Furnace is designed to
operate on diesel #2 fuel oil only. The Dragon can
operate for a minimum of 8 hours using the internal
tank that holds 9.3 gallons (35 L). Do not run the
Dragon out of fuel, as it may be difficult to restart. For
longer unattended use, it is recommended that you
purchase a larger, DOT-approved external fuel tank to
use with the external fuel siphon.
If external tank is used, cover opening to prevent
contaminants from entering tank. Place tank on
flat, stable surface to prevent tipping or spilling.
Failure to use diesel fuel could cause injury and
permanent damage to the unit. It may also void the
Dri-Eaz warranty.
Altitude Adjustment
NOTICE: The Dragon is factory-set for use at
elevations up to 2000 feet above sea level. For use
above 2000 feet or for any subsequent change of
elevation, higher or lower, the unit must be adjusted by
a qualified HVAC technician to avoid excessive soot
build-up and possible flue fire. Always have a qualified
HVAC technician adjust the unit for operating at the
altitude of the intended use.
Failure to adjust for
altitude changes could cause injury, permanent
damage to the unit and secondary damage when
ducting into a structure. It may also void the Dri-
Eaz warranty.
Black or gray/white smoke coming from
the flue indicates an improper air to fuel ratio and that
the unit must be adjusted. Call an HVAC specialist for
assistance, or an authorized service center for referral
to an HVAC technician. For further questions, call Dri-
Eaz Service at 800-932-3030.
OVERVIEW
Introduction
The Dragon K85 Mobile Furnace is an indirect fired
heater. It supplies heated air to an area without adding
any moisture or fumes through the heating process.
The Dragon is able to do this by using a heat
exchanger so that the process air never comes into
direct contact with the flame in the combustion
chamber.
The Dragon operates from outside the structure. It
draws in the ambient outdoor air and increases its
temperature by 81°F. 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
affected area.
The clean, dry heat from the Dragon helps reduce
drying times while maintaining stable and comfortable
temperatures. The Dragon is ideal for any number of
applications, including:
x
water damage restoration
x
new
construction drying
x
unheated jobsites
x
temporary event shelters
x
any situation calling for clean, dry heat
Principles of Use
For applications like water damage restoration and
new construction drying, the Dragon can increase
drying efficiency.
