You can connect a regulator and flashback arrestor to the gas outlet fitting
When connecting the regulator to the Torch Booster use sealant tape on the high-pressure
outlet fitting on the Torch Booster. Be sure to hold a wrench on the high pressure
outlet fitting when screwing on the regulator to relieve pressure on the fitting.
Failure to do so may result in twisting the internal piping and voiding the warranty.
Connect a “Regulator Mount” flashback arrestor check valve to the regulator.
If you are connecting the Torch Booster to a pipe manifold put a B to NPT adapter
on the end of the flashback arrestor check valve for connection to a pipe going to
multiple torches (see photo).
Start with the right tools! - You will need a roll of Teflon sealant tape, 4 sizes
of open end wrenches ( 9/16”, 5/8”,3/4” and 7/8”)
and an adjustable wrench that opens at to least 1 1/4”.
Install a tee pipe in the building gas line
The building gas supply pipe should be at least 1/2” diameter for TB-15/30, 3/4”
diameter for TB-60 and 1” diameter for TB-125. Gas pressure should be between
¼ psi to 1 psi; in some circumstances TB-60/125 can accept supply pressure
as high as 5 psi - Call G-TEC before installing a unit on a building gas pipe
with greater than 1 psi.
A qualified technician should install a tee in the existing gas line with a 1/2”
male fitting for the TB-15/30 or 3/4” for the TB-60/125 Torch Booster. Do not attempt
this installation yourself unless you are qualified to work on natural gas pipes.
This is a general description of how to install G-TECTorch Boosters - please read
the User’s Installation and Information Manual that is included with with your Torch
Booster for complete installation details.
Note: Torch Boosters must be installed by a person qualified to work on natural gas
pipes.
Do not install your Torch Booster yourself unless you are qualified.
Connect the flexible supply hose to the shutoff valve
After the shutoff valve is connected to the supply pipe screw the adapter fitting
into the ball valve. Be sure to use sealant tape for this fitting and tighten the
adapter with a 7/8” open ended wrench.
Start the Torch Booster!
How To Start Your TB-15/30 Torch Booster
- Before starting the Torch Booster be sure a torch is attached and the valves are
closed. The Torch Booster will not start if there is an open gas outlet.
- On the left side of the Torch Booster flip the ON switch up - the green ON and
amber RESET lights will turn on and the fans will start.
- Press the START button on the right side and hold it down until the amber RESET
light goes out - the red COMPRESSOR light in the middle stays on. The Torch Booster
will now continue to run by itself. If the START button is released before the amber
RESET light turns off the Torch Booster is designed to shut itself off.
- To turn the Torch Booster off press the ON switch on the left side down.
How To Start Your TB-60 or TB-125 Torch Booster
- Before starting the Torch Booster be sure a torch is attached and the valves are
closed. The Torch Booster will not start if there is an open gas outlet.
- On the left side of the Torch Booster press the green button - the light above
it and the RESET light on the right side of the cabinet will turn on.
- On the right side press and hold the black START button until the RESET light above
it goes out and the COMPRESSOR light in the center turns on. The Torch Booster will
now continue to run by itself. If the START button is released before the COMPRESSOR
light turns on the Torch Booster is designed to shut itself off.
Or, connect your own regulator to the Torch Booster
If you already own a regulator with a CGA 510 fitting (this is the same fitting that
screws into a propane BBQ tank) then you can use it with your Torch Booster. Your
system includes a female CGA 510 fitting and adapter for connection to the Torch
Booster. Be sure to install a “Regulator Mount” flashback arrestor on the regulator,
or a “Torch Mount” flashback arrestor on your torch. If you use a regulator like
the one in the photo put something under the regulator body to support it’s weight.
Connect the supply hose to the shutoff valve and the gas inlet fitting on the back
of the Torch Booster
You must use the hose supplied by G-TEC. Do not substitute any other hose, hard pipe
or yellow flex hose. Safety equipment inside the Torch Booster is calibrated to the
hose provided and anything else will cause the system to shut down without warning.
Use a 3/4” wrench to connect the hose to the shutoff valve for all Boosters. For
TB-15/30 use a 9/16” wrench to connect the hose to the Booster. For TB-60/125 use
a 3/4” wrench to connect the hose the the Booster.
If there is a lock washer on the Booster you can do this step with one wrench. If
there is not a lock washer on the Booster use a second wrench to brace the nut on
the fitting on the Booster while tightening the hose. Failure to do this may twist
the copper tubing inside the Booster and VOID THE WARRANTY.
If there is not a lock washer then use a second wrench to brace this fitting when
tightening the hose
Or, connect a torch directly to the Torch Booster
You may connect a torch directly to the Torch Booster and G-TEC provides an adapter
that presents a “B” fitting to your torch hose. If you attach a torch directly to
the Torch Booster be sure to install “Torch Mount” flashback arrestor check valves
on the torch for safety.
Now test all hose and fitting connections with soapy water to be sure there are no
gas leaks.
If there are gas leaks re-tighten the connection until the leak stops.
Wrap the end of the gas pipe
with Teflon tape
Screw the shutoff valve onto
the pipe and tighten with
the crescent wrench.
Connect the ball valve to the gas line
G-TEC includes a 1/2” shutoff valve with TB-15/30 and a 3/4” shutoff valve with TB-60/125.
Apply Teflon sealant tape to the thread on the male pipe end then tightly screw the
shutoff valve onto the pipe.
The gas supply pipe is connected to the low pressure inlet (¼ to 1 psi) in this
photo.
NOTICE: If your Torch Booster makes a rapid clicking sound when starting STOP IMMEDIATELY
AND CALL G-TEC AT 1-800-451-8294. A simple adjustment that is done with a screwdriver
is needed but continuing to try to start the Booster can damage a $ 300 part. We
will explain how to make the adjustment when you call.
Start the Torch Booster!
How To Start Your TB-250/500 Torch Booster

closed or the Booster is connected to a shop manifold. The Torch Booster will not
continue to run if there is an open gas outlet.
- On the left side of the Torch Booster press the green button - the light above
it and the RESET light on the right side of the cabinet will turn on and the fans
will start.
- On the right side press and hold the black START button - the red COMPRESSOR light
at the top center of the cabinet will turn on and the compressor(s) will start to
run. Continue to press the black button until the RESET light above it goes out.
The Torch Booster will now continue to run by itself. If the START button is released
before the RESET light goes out the Torch Booster will shut itself off.
Installation Overview For G-TEC Torch Boosters
Installation Overview For TB-15/30/60 and TB-125 Torch Boosters
Installation Overview For TB-250 and TB-500 Torch Boosters
TB-250 and TB-500 Torch Boosters and Refueler 180 Cylinder Filling Systems are hard
piped to the low-pressure natural gas pipeline. There are two gas inlet fittings
on the rear panel of the unit: the fitting on the left side is for gas supply pressure
between 1 to 5 psi and the inlet fitting closer to the red/yellow cutoff switch is
for gas pressure between ¼ to 1 psi. Whichever inlet fitting you connect to, cap
the other fitting with a metal cap using Teflon sealant. If air gets into the Torch
Booster/Refueler it will VOID THE WARRANTY and destroy the compressors.
These units require a minimum 1 1/2” diameter supply pipe to come as close as possible
to the point of connection before breaking down to a 3/4” pipe to connect to the
inlet on the cabinet. The 3/4” pipe should be as short and with as few bends as possible.
Cabinet dimensions are 28”W x 24” D x 20”T - allow 12” space on all sides of the
cabinet. Place the unit on a tabletop - we recommend AGAINST placing the unit under
a table/shelf or where a ladder is required for access. Once per year the cover must
be removed to perform scheduled maintenance - place the unit where it will be easy
to do this work.
System weights are TB-250 - 175 lb, TB-500 - 285 lb, Refueler 180 - 175 lb
Electrical requirement for the Refueler 180 is 120 V 30 amp service. For the TB-250
and TB-500 Torch Boosters the electrical requirement is 208 single phase 30 amp and
it is essential that power supply meet this parameter - measure your power supply
when the Booster’s compressors are running to be sure. Voltage in excess of 220V
or lower than 200V will cause high amperage, burning at wire connections and VOID
THE WARRANTY. Some customers assume their power supply is 208V and don’t actually
measure it until they start to experience shutdown problems.
