NOTICE:
Never use gasoline or crankcase drainings
for fuel.
NOTICE:
Do open the fuel cap or fill the tank while
the unit is operating.
Attach exhaust stack
Before operating the Dragon, affix the provided
exhaust stack with rain cap to the flue opening by
slipping the stack over the flue opening (Fig. A). If
the stack does not fit snugly, drive small sheet metal
screws through the base of the stack into the
exhaust outlet to secure the stack. To prevent
damage to the unit, remove the stack when
transporting the Dragon.
NOTICE:
Do not operate the Dragon without the
exhaust stack in place. The flue pipe must be at
least two feet long and provide sufficient draft to
assure safe and proper operation of the heater.
Install ducting
1. Attach the ducting on the heated air outlet (Fig. A)
and secure it with the clamp provided.
2. Place the other end of the ducting into a suitable
inlet in the structure.
Place thermostat sensor
Place the thermostat sensor into the space being
heated. For more accurate control, we recommend
placing the sensor in an area where the air is flowing
freely. The burner will automatically turn off when the
temperature in the monitored area reaches the
setpoint, or a maximum of 105°F (41°C), in order to
help operators comply with the RIA Safe Harbor
clause.
Plug in unit
Use an extension cord to connect the unit to a 115V
circuit rated for at least 10 amps. 230V units should be
connected to circuits rated for at least 10 amps. On
115V units, the cord plug will glow when electricity is
present.
OPERATING THE DRAGON
Inspect 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. See Fuel Type (see p. 3) for
fuel requirements.
2. Turn the CONTROL KNOB to the Heat position
(Fig. C).
You will hear the burner ignite. The burner will operate
a few minutes until the internal heat exchanger
reaches operating temperature. Then the fan will turn
on and the unit will begin producing heat.
NOTE: It is normal to see a small amount of smoke
when starting or stopping the unit. If smoke continues
for more than a few seconds, turn off the unit and see
“Adjusting for proper combustion and altitude,” p. 5.
NOTE:
At temperatures of 35°F / 2°C or below,
wait
25
–30 minutes after plugging in the unit before
turning the CONTROL KNOB to Heat
. This allows
time for the burner nozzle preheater to bring the fuel
up to the correct operating temperature. The
preheating feature is not available on 230V units.
NOTICE.
Monitor the settings on the Dragon and
conditions in the structure at least once a day to
ensure proper operation.
Controlling the temperature
Set the desired temperature F on the THERMOSTAT
control from a range of 70°
–105°F / 21°–41°C.
