RED DRAGON PROPANE FLARE OPERATING INSTRUCTIONS
BEFORE OPERATING THE RED DRAGON PROPANE FLARE:
Make sure you have selected a safe area for placement and operation with
approximately 40 foot radius and a minimum 50 feet of vertical clearance.
1. Attach pilot hose to an LPG fuel supply with at least
five gallon capacity.
2. Attach the main evacuation line to the tank being
evacuated. This connection will be either a P.O.L
fitting or a commercial tank connection, depending on
the model.
3. Slightly open each tank, one at a time, and test for
leaks at all connections to the Solenoid Control Box
using soapy water or commercial leak testing fluid.
Turn off tanks and correct any leaks before continuing.
Repeat this step if you have to correct leaks until none
are found.
4. Make certain that the main and remote switches are
in the "OFF" position. Slowly open each tank valve
fully. Connect electrical power cord to a 110 volt A.C.
power source.
NOTE: The pilot hose is equipped with a safety P.O.L. fitting.
If the valve on the pilot fuel container is turned on too
quickly, the P.O.L. fitting will check (you may hear a click)
just as it would if the hose ruptured. This check valve
restricts flow and will result in failure of the pilot to light or
result in an insufficient pilot flame. REMEMBER, ALWAYS
TURN THE TANK ON SLOWLY!
5. After making certain the remote switch is in the
"OFF" position, move the main switch to the "ON"
position. The RED indicator light will come on. The
pilot torch should now automatically light.
NOTE: It is possible you will hear the buzzing sound of
the electrical spark attempting to light the pilot burner.
The ignition system will cycle in seven seconds. The
ignition system will attempt to re-light after a 7 second
delay. A third ignition will be attempted. Failure to
establish a pilot results in the unit locking out.
Should the pilot not achieve ignition, turn the main
switch "OFF", wait 30 seconds and start again. It
may be necessary to repeat this procedure several
times to purge sufficient fuel through the pilot fuel
lines.
Once the pilot is burning, the system will continue
to monitor itself. If the pilot torch goes out, an
automatic relight is attempted. If reignition does
not occur within 10 seconds, the system will
automatically shut down and the operator should
start again at step 4 in these instructions.
6. After pilot is ignited, move the remote switch to
the "ON" position to start evacuation of the main
tank.Leak test hose connections from torch and
flare tube to the solenoid control box using soapy
water or commercial leak detector.
LIGHTING PROCEDURES
SHUT DOWN PROCEDURES
1. Turn the valve off on the tank being evacuated and allow all LP-Gas to escape from the fuel line.
2. Turn the remote switch to "OFF".
3. Close the pilot tank valve.
4. After pilot has burned out, turn main switch to "OFF".
5. Disconnect the unit from the power supply and disconnect hoses from both tanks.
Before Starting, Make sure the "Main" switch and the "Remote" switch are in the "OFF" position.

CARE AND MAINTENANCE
1. Check all screws on the terminal strips in the electronic control box for tightness before and after each use.
Tighten if needed.
2. Store the unit in a dry place to protect the burners and ignition system components.
3. Always leak check all connections before each use and correct as necessary before lighting. DO NOT operate
the unit if any leaks are present.
RED DRAGON PROPANE FLARE OPERATING INSTRUCTIONS
TROUBLE SHOOTING TIPS
Ignition and Heat Sensor:
The ignition and heat sensor electrodes can be sensitive. If unit is not lighting or staying lit, make sure the electrodes
have a 90° angle and that the gap between the ignitor and the ground is 1/4". The ignitor and ignitor ground wire
should be over the pilot torch bell an 1/8" - 1/4" and the heat sensor wire should just barely cross the edge as
shown below.
The flare solenoid will only activate when pilot flame is sensed. If flare solenoid fails to activate double check the
position of the heat sensor wire and make sure it is positioned as shown below.

Make Sure The Electrodes are
Positioned as Shown Here.
To test the ignition:
Make sure both fuel source valves are "CLOSED" (Pilot Tank and Main Fuel
Source to be flared). Turn the main switch to "ON" and then turn the remote
switch to "ON" and watch for a strong spark between ignitor and ground. If a
stong spark is not noticed turn switches off and adjust electrodes as shown in
these diagrams. Keep hands and head a safe distance away from the flare
head as there may be a small amount of fuel left in the lines.
Flaring in the Wind:
The Red Dragon Flare can operate in winds up to 25 mph. It may be necessary to
rotate the flare so the electrodes and heat sensor are situated in the pilot flame but
not exposed to the fuel coming from the evacuation flare tube.
Wind Direction
Flaring in the Rain:
Flaring may not be possible in rainy conditions. Rain may extinquish the pilot
or cool the heat sensor enough to where it will shut-down the flare solenoid.
WARNING:
Keep all parts of the body away from the
electrodes. This system creates a high
voltage spark and can cause injury or death.
DO NOT service this unit if you have a
pacemaker.

Lengthy Flare Jobs and the Pilot Fuel Source:
Always use a separate cylinder for the pilot source and have more than one pilot cylinder available for lengthy
flaring situations. The pilot fuel source may become empty or drop below 18 P.S.I. and have to be replaced
before the tank being evacuated is completely empty. When the pilot tank empties or drops below 18 P.S.I.
the pilot will/may quit burning and raw LP gas could be released into the atmosphere. Follow the shut-down
procedures and replace the pilot cylinder. Repeat lighting instructions to continue.
IMPORTANT NOTE: YOU SHOULD NOT USE THE SAME TANK YOU ARE EVACUATING FOR YOUR
PILOT SOURCE.
Tank Freeze-Up and the Refrigeration Effect:
Tank freeze-up or pressure loss may occur when evacuating vapor withdrawl containers, especially while
operating at outside temperatures below 50° F. Pilot containers may also be effected. Frost build up on the
outside of the tanks, fittings and hoses are indicators of excessive refrigeration.
If the tank being evacuated is losing pressure, yet still contains fuel, you may be required to cease the flaring
procedure for a few minutes to let the tank defrost. This effect can and will happen to the fuel tank being
evacuated. Other side effects are the flare tube may accumulate frost (the frost in this case contains
propane). In the right conditions this frost is flammable.
If the pilot tank is losing pressure or freezing up, replace it with a larger cylinder.
As the evacuation tank pressure drops, the speed of the process is reduced.
The fuel in the LP cylinder is being evacuated and burned at tank pressure. As the fuel is being consumed the
pressure in the cylinder will drop. Outside temperature also has a direct effect on tank pressure.
Therefore, the flare will not produce 529 gallons per hour consumption up to the very last second. A fuel
cylinder being evacuated on an 85 degree Fahrenheit day will flare faster than a fuel cylinder being evacuated
on a 40 degree Fahrenheit day.
Flaring In Extreme Conditions:
Certain components of the Ignition and Solenoid Control Box are not designed to be operated in temperatures
exceeding 125° F (54° C) or below -20° F (-32° C).
