Removing a gas line from a fryer must always be done carefully to prevent leaks, fires, or equipment damage. Whether you’re relocating your fryer, performing maintenance, or replacing a hose, it’s critical to follow the correct disconnection procedures.

This guide explains how to safely remove the gas line from a commercial fryer, what tools you need, and how to inspect and reattach connections afterward. It also highlights how MLP Kitchen Equipment designs its commercial Gas Fryers with easy-access gas inlets and certified fittings to make maintenance and installation safer and faster.

1. Why Gas Line Removal Must Be Done Carefully

A gas fryer operates under pressurized natural gas or liquefied propane (LP). Mishandling the gas connection can cause:

• Gas leaks, which pose explosion or fire risks.

• Damage to the gas valve or regulator, affecting performance.

• Contamination or moisture entry, leading to ignition problems later.

Following proper safety steps ensures both personal safety and equipment reliability.

3. Step-by-Step: How To Remove Gas Line From Fryer Safely

Step 1: Turn Off the Fryer

Switch the fryer’s power and gas control knobs to the OFF position. Allow the fryer to cool completely — hot oil and metal parts can cause serious burns.

Step 2: Shut Off the Main Gas Supply

Locate the shutoff valve on the gas line (usually a lever-type valve behind or under the fryer).

• Turn the valve perpendicular (crosswise) to the gas pipe to close it fully.

• For propane systems, close the cylinder valve tightly at the tank.

This stops gas flow and depressurizes the line before disconnection.

Step 3: Vent Any Remaining Gas Pressure

After closing the supply valve, wait 2–3 minutes to allow residual gas pressure to dissipate.
You may hear a brief hiss — this is normal as trapped gas escapes safely.

Step 4: Loosen the Hose Connection

Using an adjustable wrench, gently loosen the fitting connecting the hose to the fryer inlet.

• Always hold the fryer’s gas inlet steady with another wrench to prevent twisting or damaging internal threads.

• Turn counterclockwise to loosen the nut.

If the connection is tight, apply steady, even pressure — avoid jerking motions that could strain the joint.

Step 5: Detach the Gas Hose

Once loose, carefully pull the gas hose away from the fryer inlet.
If the hose is still pressurized or smells strongly of gas, immediately step back and recheck that the supply valve is fully closed.

Step 6: Cap or Cover the Gas Inlet

If the fryer will remain disconnected for a while:

• Use a threaded safety cap or plastic cover to seal the open gas inlet.

• This prevents dust, grease, or moisture from entering the valve assembly.

For propane systems, also place a cap on the regulator outlet.

Step 7: Clean the Fittings

Wipe both the hose and inlet fittings with a soft, dry cloth to remove oil residue or dust.
Inspect the threads for wear, cracks, or rust. Damaged fittings should be replaced before reconnecting.

4. Reconnecting or Replacing the Gas Line

If you plan to reinstall or replace the gas hose:

1. Apply a thin layer of gas-rated thread sealant or PTFE tape to the male threads.

2. Tighten the connection securely using a wrench.

3. Open the gas supply slowly and spray soapy water onto the joint.

4. Watch for bubbles — if any appear, tighten again or replace the fitting.

Never use open flames (matches or lighters) to test for leaks.

5. Important Safety Tips

Proper safety practices protect both personnel and equipment.

6. Common Mistakes to Avoid

Taking an extra minute to double-check connections prevents costly accidents.
