Frequently Asked Questions - Karu 12 Gas Burner OONI

How to light the Ooni Karu 12 gas burner?

Make sure the control knob is in the OFF position. Open the propane cylinder valve slowly counterclockwise. Push in the control knob and turn it slowly counterclockwise until you hear a click and the burner ignites. Hold for 5 seconds then release.

What to do if the burner does not light?

Turn off the control knob, wait 5 minutes then repeat the procedure. If that does not work, try lighting with a match and the provided match holder through the front hatch. Also check that the cylinder is not empty and the hose is not damaged.

Why is my oven not heating enough?

Possible causes: empty gas cylinder, cracked or leaking hose, improperly attached regulator, or use in very windy weather. Make sure the cylinder is full, the hose is in good condition, and the regulator is properly connected.

What to do if I smell gas?

Immediately shut off the gas supply at the cylinder. Extinguish any open flame. If the odor persists, move away from the appliance and call the fire department. Do not reuse the appliance until the tightness has been checked.

How to check the tightness of connections?

Prepare a soap and water solution. Apply it to all connections with a spray bottle. If bubbles appear, there is a leak. Tighten the connections or replace defective parts. Never check with an open flame.

What is the correct cleaning procedure?

Make sure the gas supply is turned off and the appliance has cooled. Remove the door and the fuel tray. Gently clean the FSD probe and burner holes with a damp cloth. Let dry completely before relighting.

Can I use this oven indoors?

No. The appliance is designed for outdoor use only. Never use it in a building, garage, or any other enclosed space, as this may lead to carbon monoxide poisoning or fire.

What gas cylinder to use?

Use a standard 20 lb (approx. 9 kg) liquid propane cylinder with a QCC-compatible valve. Make sure the cylinder is equipped with an overfill prevention device (OPD). Never fill beyond 80%.

Why is the flame yellow or blue?

The flame color can vary depending on the environment, food being cooked, ambient temperature, and appliance condition. This does not affect taste or cooking quality. If the flame is consistently yellow or unstable, check burner cleanliness.

What to do if the burner goes out during use?

Immediately turn off the gas at the cylinder and the control knob. Wait 5 minutes before relighting. Check that the FSD probe is clean and oxygen intake is sufficient (chimney vent open). If the problem persists, inspect the hose and regulator.
