Restarting after thermal overload
1Eit
lithe temperature of the heat exchanger exceeds
2507
(121°C). the Dragon will automatically shut down to
protect against thermal overload and must be reset
before it will start again. The most common cause of
thermal overload is restricted airflow. To help prevent
thermal overload you should
• Make ducting runs as straight and short as possible
• Keep the ducting free of debris and unobstructed
• Keep the air intake grill unobstructed
To restart the Dragon after a thermal overload shutoff,
1. Turn the CONTROL KNOB to "Manual' or
"Thermostat".
2. Press in the red HI-TEMP LIMIT switch (Fig. 1, D).
If the thermal overload switch continues to shut off the
Dragon. contact the Dri-Eaz Service Department at

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 BURNER
CONTROL BUTTON (Fig. 1, G) will glow red. The fan
may continue to cycle on and off until cooling is
completed. Follow these instructions for restarting.

Tip:
It may be necessary to repeat these steps three or
four times until the fuel pump can refill the fuel lines and
provide sufficient fuel for heater operation.
1. Turn the CONTROL KNOB to the off position.
2. Refill fuel tank.
3. Turn
the CONTROL KNOB to either the "rnanual" or
.4
"thermostat
-
position.
Press the BURNER RESET BUTTON once. The fuel
pump will begin pumping fuel through the fuel line and
the burner should ignite after 20 seconds.
5. If the pump turns off before the burner ignites, the
reset button musl be pushed again. This occurs
because the heater does not yet have sufficient fuel
to operate.
6.
If
the burner has not started after the third attempt,
the burner control light will flash red. To reset, press
and hold the BURNER RESET BUTTON for 15
seconds until the light goes out. Now you may repeat
steps 2-5 as necessary until the burner ignites.
Tip:
If
the unit will not restart after several attempts,
contact Dri-Eaz Service at 800-932-3030.
NOTICE: You should continue to physically check the
Dragon at least once a day during operation. Check for
leaks, and observe the exhaust smoke to ensure that its
still clear.
CAUTION:
Always use clean fuel and a trusted fuel
source to prevent fuel problems. Be sure to replace the
fuel tank cap to prevent moisture or contaminants from
getting into the fuel.
