The fuel transfer device supports isobutane fuel canisters.

STEP 1: Place receiving canister in the freezer, ice chest, or a cool shaded area. Place sending canister in the sun.

STEP 2: Wait 5 to 10 minutes. This allows the fuel canisters to create a temperature differential that facilitates the transfer.

STEP 3: Thread canisters onto FlipFuel device. Sending canister on top ("OUT") side, receiving canister on bottom ("IN") side. Hand tighten.

STEP 4: Open valve to transfer fuel. Once fuel transfer is complete, close valve and detach isobutane fuel canisters.

NOTICE: Be sure to not overfill canisters, as they may function improperly. A digital scale is the best way to ensure you do not exceed the canisters limit. 

Only transfer fuel between two canisters of the same brand and model.
