Install a tee fitting in the building gas line
Do not attempt this installation yourself unless you are qualified to work on natural
gas pipes. For most applications gas supply pressure should be between ¼ to 1 psi….some
applications can support up to 5 psi gas supply but this should be discussed with
Connect the ball valve to the gas line
Or, connect a torch directly to the Torch Booster
You may connect a torch directly to the Torch Booster and G-
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 onto 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.
Connect the other end of the supply hose to the gas inlet fitting on the back of
the Torch Booster/Refueler 60/DM-
You must use the hose supplied by G-
You will need two wrenches for this step. Use a 9/16” wrench on the nut at the end
of the hose for the TB-
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. Next, screw the flexible hose onto the adapter with a 3/4” wrench.
Brace this fitting
Wrap the end of the gas pipe
with Teflon tape
Screw the shutoff valve onto
the pipe and tighten with
the crescent wrench.
Connect a regulator and flashback arrestor to the gas outlet fitting if you have a Torch Booster
When installing the regulator on the Torch Booster use sealant tape on the high-
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 the pipe going
to the jewelers’ torches. This adapter is not part of the Torch Booster system but
can be ordered from G-
Connect your Refueler to your natural gas cylinder, or G-
Your Refueler comes with a hose to connect to either single cylinder (left) or a

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.
Electrical requirement for the Refueler 180 is 120 V 30 amp service. For the TB-
The gas supply pipe is connected to the low pressure inlet (¼ to 1 psi) in this photo.
Supply pipe diameter varies between 1/2” and 1” depending on Booster model and power
requirement is 120 V 15 amp for all systems except TB-
