Screw the fuel hose connector onto the threaded valve of your gas canister. Ensure it is hand-tightened securely to prevent gas leaks. Do not overtighten. - Check for Leaks: Apply a small amount of soapy water to the connection point between the stove and the fuel canister. If bubbles appear, there is a leak. Tighten the connection or replace the canister if necessary. Do not proceed until all leaks are resolved.

Operating Instructions
- Prepare for Ignition: Ensure the stove is stable and the fuel canister is connected. Place your cookware on the pot supports.
- Open Gas Valve: Slowly turn the gas control knob on the fuel line counter-clockwise to allow a small amount of gas to flow. You should hear a faint hissing sound.
- Ignite the Stove: Press the electric ignition button firmly. The stove should ignite with a blue flame. If it does not ignite after a few attempts, turn off the gas, wait a minute, and try again. If the electric ignition fails, use a long-stem lighter or match to ignite the gas manually.
