* Most foot pedals tend to have similar hose setups:

A) Oxygen
1) A long hose runs from your oxygen tank to the pedal.
2) A short hose runs from the pedal to the center fire oxygen intake on the torch.
3) Another short hose runs from the pedal to the outer fire oxygen intake on the torch.

(it does make a difference which short hose goes to the center fire and to the outer fire)

B) Gas
1) A long hose runs from your propane tank to the pedal.
2) A short hose runs from the pedal to the center fire gas intake on the torch.
3) Another short hose runs from the pedal to the outer fire gas intake on the torch.

(it does make a difference which short hose goes to the center fire and to the outer fire)

If you install flashback arrestors at the torch (vs. at the regulator), I would suggest putting them between the pedal and the torch. This means 2 gas flashback arrestors and 2 oxygen flashback arrestors.

* If you choose not to install a foot pedal (you can always add one later):

A) Oxygen
1) Connect a short hose to the inner flame oxygen inlet at the torch
2) Connect another short hose to the outer flame oxygen inlet at the torch
3) Connect these two hoses to a Y adapter
4) Connect a long hose from the Y adapter to your oxygen tank

B) Gas
1) Connect a short hose to the inner flame gas inlet at the torch
2) Connect another short hose to the outer flame gas inlet at the torch
3) Connect these two hoses to a Y adapter
4) Connect a long hose from the Y adapter to your propane tank

In this case, I don't see a problem using just one set of flashback arrestors (1 gas and 1 oxygen) between the Y adapters and the tanks.
