Securing ducting to the structure
In most drying situations you will need to attach the end
of the ducting to an opening in the structure such as a
basement window or crawlspace vent block. Since each
structure is unique, you will usually need to build an
adapter to fit the specific opening.
Operating 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 diesel fuel to the
fuel tank. Do not overfill. See “Fuel Type,” p. 2, for
recommended fuels.
2. With the ducting secured, plug in the power cord into
a suitable outlet.
3. Place the thermostat sensor in the target area, and
turn the CONTROL KNOB to the “Thermostat”
position.
CAUTION.
Monitor the settings on the Dragon and
conditions in the structure at least once a day during
operation.
Controlling the temperature
The Dragon is equipped with a remote thermostat that
can be used to control the temperature in the target
area. To use the Dragon in thermostat mode, set the
desired temperature on the thermostat control for a
maximum of 102°F (39°C) and place the control in the
target area.
Shutting the Dragon Off
Turn the CONTROL KNOB to the “Off” position.
CAUTION:
Do not unplug the unit or otherwise turn off
the power until the fan stops operating. Failure to let the
unit complete the cooling cycle could damage the heat
exchanger and will not be covered under warranty.
Special Instructions
Bleeding the fuel line
In certain circumstances air may accumulate in the fuel
line and prevent proper operation. To remove air from
the fuel line, follow these steps:
Supplies needed: ¼ in. i.d. × 6 ft. clear plastic hose,
receptacle for fuel, rags or cloths to clean up any spills,
wrenches and screwdriver.
1. Turn the CONTROL KNOB to the “Off” position.
2. Open hood. Be sure to secure it with the retention
cable provided.
3. Loosen (but do not remove) purge valve with a
wrench. Attach a clear plastic hose over the purge
valve and place the end in a suitable receptacle on
the ground.
4. Turn CONTROL KNOB to the “Thermostat” position.
The fuel pump will run for approximately 20 seconds,
and a mixture of fuel and air will flow through the
plastic tube.
5. Press BURNER RESET BUTTON (Fig. 1, G) to
repeat the purge process. Repeat until the fuel flows
free of air bubbles.
6. Remove plastic hose and retighten bleed valve.
7. Close hood. The Dragon may now be operated
normally.
Adjusting for Altitude
The combustion air intake control for the furnace is
factory set for operation at altitudes ranging from sea
level up to 5000 ft. (1500 m). To assure proper operation
and maximum performance at higher altitudes, it is
necessary to adjust the combustion air/fuel mixture.
The best guide to proper air/fuel mixture is exhaust
color. The Dragon exhaust should always be clear.
Black or white smoke indicates an improper air/fuel
mixture:
a) If the exhaust is
clear
, no adjustment is needed.
b) If the smoke is
dark
or
black
, there is not enough air
in the mixture.
c) If the smoke is
white
, there is too much air and not
enough fuel in the mixture, or there is water in the fuel
If the smoke color is either black or white, follow
these steps to adjust the air/fuel ratio.
