ASSEMBLY, TESTING, AND OPERATING INSTRUCTIONS
PLEASE READ AND RETAIN THIS INFORMATION FOR FUTURE REFERENCE
DO NOT OPERATE this torch unless you have been properly trained or are under the supervi-
sion of someone in its proper use. Read and understand all instructions before attempting to
use!
FOR YOUR SAFETY!
This device is intended for outdoor use only with adequate ventilation.
This torch is designed for use with a vapor-withdrawal liquid propane (LP) gas cylinder 10
pound size and larger with an OPD valve.
Eye protection, gloves, proper fire retardant clothing, and boots should be worn when oper-
ating the torch.
NEVER direct torch flame toward hose or propane tank.
DO NOT leave torch unattended while torch is in operation.
NEVER point the torch at flammable materials you do not want to burn.
DO NOT stand or prop the torch on the burner end while in operation.
DO NOT use matches or a cigarette lighter to light the torch. ALWAYS use a spark lighter.
Secure LP cylinders in a level, upright position during operation. DO NOT lay tank on its
side.
DO NOT lift propane tank by the valve.
When not in use, the gas should be turned off at the LP gas cylinder valve. Close the flame
adjusting valve as well. When done using torch, disconnect torch from cylinder.
Have an ABC Fire Extinguisher readily accessible during the operation of the torch.
DO NOT apply heat or flame to tank, hose, or torch to check for leaks, or to increase the gas
pressure.
CAUTION: In daylight, the flame is barely visible. DO NOT place hands or body parts in
the path of the flame while lighting or operating the torch.
DO NOT use torch in areas where gasoline or other flammable vapors are stored or used.
CAUTION: The torch barrel becomes very hot when in use. Do not touch barrel or allow it
to come in contact with flammable materials until it has completely cooled down.
IF YOU SMELL GAS!
DO NOT operate torches or any equipment if the odor of LP gas is present.
IMMEDIATELY shut off all valves and extinguish any open flames.
Check all equipment for leaks using leak detection fluid or soapy water.
REPAIR all leaks and test for leaks prior to lighting the torch.
TROUBLE SHOOTING
Problem #3 - The Idle Boost valve is not working.
Possible Solutions:
1. If you can not get full flow out of the torch with the flame adjusting valve
all the way open, then the integral POL safety valve (built into QCC-1 Ac-
me Tank Connector) has probably detected too much gas flow and restrict-
ed the gas flow. To reset the POL safety valve, turn the LP gas cylinder
valve completely off (clockwise), then open the flame adjusting valve to
release any pressure in the hose (or remove the QCC-1 Acme Tank con-
nector from the LP gas cylinder and then reinstall), close the flame adjust-
ing valve, and then reopen the LP gas cylinder valve very slowly to keep a
lot of gas from entering the hose too quickly and tripping the POL safety
valve again.
2. If the flame goes to full flow with the flame adjusting valve all the way
open but you can’t get full flow with the Idle Boost valve handle depressed,
then the Idle Boost valve needs to be replaced. Contact KDAR Company
for a replacement Idle Boost valve (Model 24206).
3. If the flame adjusting valve just spins and spins, you might have unseated
the valve stem from the valve by accident. To fix this, you need to loosen
the nut under the flame adjusting valve knob with an adjustable wrench.
Then push the flame adjusting valve knob in towards the valve body while
turning clockwise. You should feel the threads “catch” and as you continue
to turn, the valve will close all the way. Then retighten the nut under the
flame adjusting valve knob (be careful not to over tighten it). If this doesn’t
work, then the Idle Boost valve needs to be replaced. Contact KDAR Com-
pany for a replacement Idle Boost valve (Model 24206).

TORCH DISCONNECTION AND STORAGE
1. Be sure the LP gas cylinder valve is turned completely off (clockwise).
2. Disconnect the QCC-1 Acme Tank Connector from the LP gas cylinder.
3. Replace the plastic cover on the LP gas cylinder valve outlet.
4. NEVER attempt to store the torch while it is hot. When the torch is stored
indoors or in a garage or shed, it must be disconnected from the tank in
accordance with Chapter 5 of ANSI/NFPA 58.
5. Store the torch and hose in a clean, dry and protected area.
TROUBLE SHOOTING
Problem #1 - The QCC-1 tank connector will not thread on to the LP gas
cylinder valve or doesn’t seal.
Possible Solutions:
1. Propane cylinders manufactured after 2002 have an OPD valve with both
internal and external threads. Make sure you are tightening the QCC-1
valve all the way. Older cylinders may not seal correctly.
2. Check the threads in the LP gas cylinder valve. They might be damaged.
3. If this still doesn’t fix it, your QCC-1 Acme Tank Connector might be
defective. Contact KDAR Company for a replacement QCC-1 Acme Tank
Connector (Model 24218).
Problem #2 - I found a gas leak during my assembly.
Possible Solutions:
1. If the gas is leaking around the LP gas cylinder valve, see Problem #1
above.
2. If the gas leak is near the Idle Boost valve, try tightening the female hose
adapter with a wrench to seal the leak.
3. If the hose is leaking either with a hole in the hose or around the brass fer-
rules, then the hose needs to be replaced. Contact KDAR Company for a
replacement hose (Model 24212).

ASSEMBLY INSTRUCTIONS
1. Unpack and inspect for damage. DO NOT use torch or hose if damaged.
2. Attach the hose to the Idle Boost Valve and tighten with two wrenches.
Do not use molded handle to tighten - it will break. Do not over tighten nut.
3. Attach QCC-1 tank connector to LP gas cylinder valve with OPD approved
valves. DO NOT USE THREAD COMPOUND! Remember, LP gas
cylinder is to be no less than 10 LB. capacity.
4. Make sure the knob on the flame adjusting valve is closed (all the way clock-
wise) and slowly open the LP gas cylinder valve. Check all LP gas connec-
tions for leaks using a leak detection fluid or soapy water. DO NOT
attempt to operate the torch if there is any odor of gas.

LIGHTING INSTRUCTIONS
1. IMPORTANT NOTE!!! The QCC-1 tank connector includes an internal POL safety
valve (integral flow-check valve). Opening the LP gas cylinder valve rapidly can
cause the valve to check and restrict the flow of gas. If the POL flow valve checks,
close the LP gas cylinder valve, open the flame adjusting valve on the handle to
release any pressure in the hose, reclose the flame adjusting valve on the torch han-
dle, wait 20 seconds, and then slowly open the LP Gas cylinder valve. If NO leaks
are found, proceed with lighting the torch.
2. Check all connections for leaks with leak detection fluid or soapy water. Leaks will
be indicated by bubbles forming around the source. Repair all leaks and test again
before lighting the torch.
3. Open the flame adjusting valve 2-3 turns until the sound of propane gas escaping is
heard.
4. Quickly using a flint lighter or other long handle igniting source (NO MATCHES
OR CIGARETTE LIGHTERS) ignite the torch. Make sure there is only a mini-
mum amount of gas before lighting. If you do not get the torch ignited quickly,
turn off the flame adjusting valve to stop the flow of gas and wait several minutes
for the propane gas to disperse. You may then return to step 2 above.
5. Adjust the flame using the flame adjusting valve on the torch handle to the desired
size of flame and heat.
Note: Regardless of where the flame adjusting valve is set, depressing the idle boost
valve will bypass the flame adjusting valve and provide full flow of propane to the
torch so that the torch will burn at maximum output.
TORCH SHUT OFF INSTRUCTIONS
1. Close the LP gas cylinder valve.
2. Allow the gas to completely burn out. After the flame is no longer burning, turn the
flame adjusting valve to the closed or OFF position (clockwise).
3. Be careful as the torch head is very hot and takes a long time to cool off.
4. If you are done using the torch for the day, follow the torch disconnection and
storage procedures in the next section.
