Mini CC Burner Instruction Sheet
Mini CC Instructions-1
High Oxy Mini CC
For the broadest range of flame types and the ability to work with a wide range of applications, the
high oxygen Mini CC offers an extra oxygenated flame. This allows for a high heat output with the
upper range to work with hard glass.
Pinpoint Mini CC
A special center fire allows the Pinpoint Mini CC to have a focused narrow surface-mixed flame.
Options and Accessories:
The Mini CC Burner has several options and accessories that are available. This section is intended to
provide any pertinent information for the options that may be applicable.
•Stainless Steel Head Option: Replace the brass nozzle with all stainless steel construction for longer
life and cooler operations.
•EL-2 Foot Controller / RMB Foot Controller: The EL-2 is an electronic foot-actuated positive closing
valve system. The RMB is a variable metering valve system that is metering only, not positive closing.
•In-Line Disposable Filters Option: This is a highly recommended option to filter the fuel gas (except
hydrogen) and oxygen gases prior to the burner to reduce the possibility of containments from the
feed piping and supply sources.
•Hose Options: There are many hose options. Latex hose, Welding hose, Tygon hose, Stainless Steel
Braided Hose, and Teflon lined hose to name a few. Refer to Bulletin 24D on the website for
ordering.
Surface Mixed:
The Mini CC Burner is surface mixed. Surface mixed burners deliver the gas and oxygen to the face
separately so that the mixing of gases happens as they exit the burner face. This produces a safe flame
for working with any application. Surface mixed burners do not have the possibility for combustion to
take place inside of the burner (this is commonly known as Flashback) since the gas and oxygen are not
mixed until they exit the burner. However, certain conditions (such as an internal leak) could cause a
Flashback to occur.

Mini CC Instructions-2
Control Valves:
Standard models require two valves which are, located on the back of the Mini CC Burner. One control
valve has a red handle and is used for metering the gas flow to the burner. One control valve has a
green handle and is used for metering the oxygen flow to of the burner.
These control valves are finely threaded and thus require several full turns to become fully open or fully
closed. When using these valves to control the flames, it is best to make small incremental adjustments
rather than full turns. Quick or large adjustments could cause the flame to become unstable and even
blow off of the face of the burner. In time, the user will learn the best way to control the burner for
their application.
The valve stems are threaded and secured into the valve body via a nut. This nut is threaded onto the
valve body and the stainless steel stem extends through this nut. Depending on how tightly this nut is
threaded down onto the valve body, the stainless steel stem will be harder or easier to turn. If the nut is
tightly threaded down onto the valve body, the stem will have more resistance to movement. By
loosening this nut, the stem will become easier to adjust. Loosening the nut can also cause a leak to
form around the stem from the nut sealing area. Be sure to check for leaks (see
“Checking for Leaks” )
anytime that this nut is adjusted.
When closing the control valve, the valve should be adjusted only until it seats and stops turning. The
valve should not be forced or “torque” down any further. By turning the valve handle with force,
beyond its seal positioning, once it has seated, great pressure may be placed on the seat. This will
cause the seat or valve stem to become deformed and will result in a leak that can not be fixed and will
require the replacement of the valve.
Checking for Leaks:
Before operating the Mini CC Burner for the first time and once a month (see
“Maintenance” ) the burner
should have the control valves and all connections checked for leaks. Follow the procedure below to
check for leaks.
1. Connect air at 25 PSI to the burner.
2. Dip the head of the burner into a bucket of water.
3. Cycle through the control valves turning each one on and then shutting it off. When the control
valve is opened there should be a rush of bubbles in the water. After shutting the control valve off,
wait about 30 seconds to watch for any new bubbles. If bubbles appear at any rate, this would
indicate a leak in the control valve.
4. Remove the head from the water and use the air pressure to blow out any residual water.
5. Mix soap (liquid soap is best for this) and water to form a bubbly mixture for leak detection.
6. Turn on both control valves.
7. Apply the soapy mixture to all threaded connections and valve stems. If any of these areas
produces bubbles after applying the soapy mixture, the connection may have a leak.
8. Close all control valves and disconnect the air.
If a leak is detected, contact a Carlisle Representative for assistance.

Maintenance:
Before any maintenance is performed, the user should be sure to use appropriate safety measures such
as wearing safety goggles.
•If the Mini CC Burner experiences carbon build-up (see
“Heat Build-up and Carbon Build-up” ), then
the burner should be cleaned regularly. The tubes can be cleaned using a torch tip cleaning set,
piano wire, or K filer (these must be significantly smaller than the orifice). When cleaning the tubes,
it is important to be very careful while gingerly poking at the carbon. It is very possible to have
the cleaning tool get stuck inside the burner. Also, a light amount of air flow through the torch will
cause the dislodged carbon to come out of the face of the burner rather than falling back into the
body.
•The Mini CC Burner should be checked for leaks in the valves and all threaded connections once a
month (see
“Checking for Leaks” ).

Mini CC Instructions-3
Startup and Shutdown:
To startup the Mini CC Burner, follow the procedure below.
1. First open the gas control valve and ignite the gas with either an open flame or a striker. Be sure
that your hands, clothing, and other flammable objects are not near the face of the burner while
igniting the flame.
2. Then open the oxygen control valve to produce a blue focused flame.
To shutdown the Mini CC Burner, follow the procedure below.
1. Reduce flow of all gases to burner
2. First close off the oxygen control valve.
3. Then close off the gas control valve.
Heat Build-up and Carbon Build-up:
Some inappropriate working conditions can cause heat build-up in the burner. This heat build-up will cause
damage to the burner and also present a danger to the user if a heated area of the burner is touched by
the user.
Heat build-up is the cause for carbon build-up. Carbon build-up is the formation of carbon inside of the
burner (natural byproduct of fuel gas). This often results in degraded performance of the burner and
possibly may cause carbon to expel out of the burner. Carbon that is present in the fuel gas (except
hydrogen) effectively causes the flame to have more heat potential. If the stainless steel in the burner
becomes heated to a significant level, the carbon from the fuel gas will bond to the walls of the stainless
steel. When this occurs, the burner must be cleaned (see “
Maintenance ”). Propane has a very high carbon
content and will almost certainly cause carbon build-up.
Below are some of the things the user can do to help retard heat build-up.
•Flames that have higher oxygen content run cooler. Use this type of flame whenever possible.
•Do not run the burner without some oxygen flowing through the burner.
•Do not use short flames that burn close to the face of the burner and can cause the end of tubes to
glow red.
•Do not use lazy flames that are not directed outward from the face of the burner.
•Do not work too close to a piece that would cause flame backwash.

Mini CC Instructions-4
Flame Atmospheres:
The Mini CC has a very unique flame. Please note that based on the operator’s prior burner experience, the
flame settings may not look or sound as expected. The unique flame properties of the torch demonstrate
superior performance. Refer to the illustrations below to achieve the desired flame atmospheres.
Neutral Reducing Oxidizing
Soft Glass: (COE 90 and higher)
For use with soft glass, Carlisle recommends a candle or focal length of 3/8”. On the Neutral setting, this
will present a flame that is very hot and provides radiant heat around the flame. This radiant heat lessens
the frequency of glass fractures due to temperature changes while moving in and out of the flame.
Hard Glass (aka Borosilicate COE 33):
For use with hard glass, Carlisle recommends a candle or focal length of 7/8”. Please note that the Neutral
setting of this flame will produce orange tips on the candles. However, as long as the candles are all the
same length, this should not produce reduction on borosilicate colors.
Oxygen Use:
Once a Neutral flame is achieved, adding more oxygen will produce the Oxidizing flame. An oxidizing
flame will make a more narrow flame pattern that can be used for more delicate work. It is important to
note that the extra oxygen also has a cooling effect in the flame and will lower the heat potential.
