Make ducting runs as straight and short as possible
•
Keep the ducting free of debris and unobstructed
•
Keep the air intake grill unobstructed
Restarting after running out of fuel
If the Dragon runs out of fuel, a fuel cutoff sensor will
automatically shut the heater off and the red FAILURE
light (Fig. 2) will glow. The fan may continue to cycle on
and off until cooling is completed.
Refuel the Dragon, switch on POWER and press
START. It may require several tries until sufficient fuel is
drawn through the fuel line.

If the unit will not restart after several attempts,
contact Dri-Eaz Service at 800-932-3030.

You should continue to physically check the
Dragon at least once a day during operation. Observe
the exhaust smoke to ensure that it is clear. If the
exhaust is not clear, see “Adjusting for proper
combustion,” p. 5, for instructions.
NOTICE:
Always use clean, fresh fuel and a trusted fuel
source to help prevent problems with fuel contamination.
Be sure to replace the fuel tank cap to prevent moisture

filters may be purchased from Dri-Eaz, 800-932-3030.
The filter is a spin-on type and is located inside the right
side cabinet behind the control panel. Have rags or
paper towels on hand to clean up any spills, and dispose
of the filter and waste fuel according to local regulations.
3. Servicing the burner.
To ensure proper operation, service of the burner should
be conducted by a qualified HVAC technician once a
year or at the beginning of the heating season in your
area.
4. Servicing the heat exchanger
In time, soot may accumulate in the the heat exchanger.
To ensure proper operation, this component should be
inspected once a year and cleaned if necessary by a
qualified HVAC technician. Contact your local distributor
or the Dri-Eaz Service Department at 800-932-3030 for
the location of a service center near you.
5. Cleaning the flame detector
The burner is equipped with a flame detector designed
to ensure the burner is operating properly. In time, this
sensor can become obscured by accumulated soot
deposits and will no longer operate properly. When this
happens, the unit will produce a FAILURE red light and
turn itself off. To clean the sensor, remove the cover,
and carefully work the rubber sensor boot free from the
burner. The sensor lens may be cleaned with a cotton
swab. Replace the sensor boot and the cover.
