• Do not operate this heat tool below 15 PSI or damage to the heat tool will
occur.
• Before using any heat tool, check all parts for proper function and damage to
component parts including the hose, regulator and heat tool.
• "Hidden areas such as behind walls, ceilings, floors, soffit boards and other
panels may contain flammable materials that could be ignited by the heat tool
when working in these locations. The ignition of these materials may not be
readily apparent and could result in property damage and injury to persons.
When working in these locations, keep the heat tool moving in a back and forth
motion. Lingering or pausing in one spot could ignite the panel or the material
behind it."
• Do not use the heat tool to remove paint.
• Do not point this heat tool at anyone and do not operate in an area where there
is a risk of an explosion or fire.

GENERAL SAFETY PRECAUTIONS
•
When working with any type of heat or open flame, always keep a fire
extinguisher close by.
•
Always were safety glasses and gloves (flame retardant or leather is suggested)
when shrink wrapping. Never obstruct or cover the air inlet at the back of the
heat tool. If the air flow is reduced the heat tool will not work properly.
•
When shrink wrapping outdoors, do not shrink wrap when the wind is stronger
the 10 mph.
•
When shrink wrapping indoors, make sure the work area is well ventilated.
•
Keep the work area clear of debris, wood shavings, paper products, flammable
chemicals and anything else that may catch fire from the heat of the tool.
•
Do not wear loose clothing while shrink wrapping and also keep long hair tied
back.
•
Stay alert, watch what you are doing, and use common sense when operating
the heat tool. Do not use tool while tired or under the influence of drugs,
alcohol or medication. A moment of inattention while operating the heat tool
may result in serious personal injury.
•
Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the heat tool in unexpected situations.
3
•
Never operate the heat tool with the combustor nozzle hard up against a surface;
this could ignite any material you are shrink wrapping.
•
Do not place the combustor nozzle (where the flame comes out of the heat tool)
next to anything while it is hot. Never allow the combustor nozzle to come in
contact with clothing or skin.
•
Do not look down the combustor nozzle while the tool is in operation or
attached to a fuel source.
•
The heat tool should be kept 6” – 8” away from the shrink film when in
operation. Never keep the heat on one area for more than a few seconds.
Once heat is applied to the shrink film, it will continue to shrink even after
the heat is moved away from the area.
•
Never modify the tool in any way and use only Shrinkfast replacement parts
.
•
Never operate in a basement or closed in, non-ventilated area.
•
Never operate the heat tool on an area that you cannot see.
•
Always operate the heat tool with the UL® Guard installed.

REGULATOR OPERATION & MAINTANENCE
Regulator Technical Overview:
•
The MEGR-6120 is a high capacity, pounds to pounds, industrial gas regulator.
It is designed to conform to UL® Standard 144 for use with LP Gas. The
maximum supply pressure is 250 PSIG. The maximum output pressure is
printed on the regulator nameplate.
•
This regulator is not intended for use in pressure applications below 3 PSIG and
the heat tool should not be operated at a pressure below 15 PSIG. The
operating temperature range is -40 to +200 degrees Fahrenheit.

POL – Attaches to

Hose Adapter –

Adjustable Hand Wheel
– Adjusts PSI Setting of
the Regulator

This is a variable regulator assembly and the heat tool will operate
properly between 15 PSI and 30 PSI. The pressure can be changed by
loosening the hex nut located under the black, round hand wheel on the
regulator assembly and then turning the hand wheel to the desired pressure.
However, the optimum and factory recommendation is that you do not
adjust the pressure and keep the regulator set at the factory setting of 22
PSI.
Regulator Installation:
1. Remove the yellow cap from the POL (brass, bull nose fitting) and connect the
POL to your propane tank and tighten with the supplied wrench (all threads
are left handed thread, so tighten counter clockwise).

2. Connect one end of the supplied 25’ hose to the hose adapter on the regulator
and the other end of the hose to the heat tool. Tighten all fittings with the
supplied wrench (left handed threads, so tighten counter clockwise).
3. Open the propane tank valve and check for any leaks by spraying a soapy
water mixture on the fittings. If any bubbles are visible, shut off the propane
tank and tighten the fittings.
4. When you first turn on the propane tank, the pressure gauge on the regulator
will slowly move toward the factory setting of 22 PSIG. Once the hose is fully
pressurized, the needle on the gauge will stop at 22 PSIG. Now the heat tool is
ready to be fired.
To open the flow of
propane, turn the tank
hand wheel in a counter
clockwise motion and
watch the regulator gauge
increase to the required
22 PSI.

STARTING THE HEAT TOOL
1. Depress the yellow safety that sits in the palm of your hand. If you do not
depress the safety first, you will not be able to pull the trigger with your finger
tips and ignite the heat tool.
2. With the safety depressed, slowly pull the trigger with your fingertips so you
first hear a slight “hissing” of propane flow, then pull the trigger completely
and the heat tool will “click” then ignite.
3. Should the gun fail to ignite, release both the safety and trigger fully to ensure
that the igniter is reset and repeat the starting procedure.
WARNING: MANY NEW USERS PULL THE TRIGGER TOO
QUICKLY AND MULTIPLE TIMES BELIEVING THIS IS THE BEST
WAY TO IGNITE THE HEAT TOOL. PULLING THE TRIGGER TOO
QUICKLY DOES NOT ALLOW THE PIEZO CRYSTAL INSIDE THE
IGNITER TO SEND PROPER VOLTAGE TO THE SPARK PLUG, SO
PULL THE TRIGGER SLOWLY IN ORDER TO IGNITE EVERY TIME.
WARNING: DO NOT TOUCH THE WIRE METAL SHIELD (UL®
GUARD) AFTER THE HEAT TOOL HAS BEEN FIRED.

REGULATOR MAINTENANCE & SAFETY FEATURES
• Because the Shrinkfast UL® approved regulator assembly is assembled and tested at the
factory to conform to UL® Standard 144, any maintenance or repairs should be in
accordance with this listing as well as any other applicable regulations. Regulator parts
showing wear should be replaced as necessary. Contact your local distributor or
Shrinkfast directly for descriptions and part numbers.
IMPORTANT SAFETY FEATURE: Inside the POL fitting on the
Regulator Assembly there is a safety featured called the “Excess Flow Device”.
• This safety feature is designed to stop the flow of propane if the hose becomes
cut or detached from the regulator or heat tool during operation.
• The Excess Flow Device does not stop the propane flow 100%, but it does
reduce the flow so the user has time to get to the tank and shut off the propane
and prevent a dangerous situation from occurring.
How the Excess Flow Device Works:
• When the propane tank is first turned on the Excess Flow Device believes there
may be a downstream leak and temporarily closes the POL. The POL does not
stop the flow entirely, so there is enough propane entering the hose to begin
pressurizing the system.
9
• Once the fuel has filled the entire hose and the regulator gauge reaches 22 PSI,
the Excess Flow Device reopens and the heat tool is ready for operation (you
will hear an audible “click” from the POL when the pressurization is
complete).
• This pressurization process can take anywhere from 7-10 seconds from when
the tank is first turned on and may take a little longer with propane tanks that
are partially filled. This feature is all for the safety of the user, but you must
wait the 7-10 seconds for the pressurization to complete before operation.
Attempting to Ignite the Heat Tool before Pressurization is Complete:
• If the user attempts to fire the heat tool before the pressurization is complete,
the pressure gauge will drop down to 0 PSI and the heat tool will not ignite. In
order to ignite the heat tool, the user must wait for the system to pressurize (22
PSI) and then the heat tool will operate properly. *This wait time will only
occur when the user first turns on the propane tank.*
WARNING: As the amount of propane in the tank drops, the pressure
gauge on the regulator will decrease accordingly. Do not operate the heat
tool once the pressure drops down to 15 PSIG. Operating the heat tool
below 15 PSIG, will result in damage to the heat tool’s internal components.

CHOOSING THE CORRECT PROPANE TANK (CONTINUED)
• Propane tanks are available in a variety of sizes. The most popular tank sizes:
• 20 lb. tank similar to a BBQ propane tank for smaller
applications.
• 40 lb. tanks are commonly used in most industrial applications.
