A low flame in your Gozney oven usually points to a gas supply or regulator issue. This guide walks you through the most common causes and the steps to restore full heat.
Quick Answer
A low flame in your Gozney oven is most often caused by a gas supply issue—either a nearly empty propane tank, a kinked hose, or a tripped regulator. Start by checking the tank level and hose path, then reset the regulator if needed. If the problem persists, the burner itself may need replacement.
Check the Propane Tank Level
The most common reason for a low flame is a tank that's running low on propane. When the liquid level drops, the pressure can fall off, especially in cold weather. If you have a spare tank, swap it and see if the flame returns to full strength. If you don't have a spare, weigh the tank or pour warm water down the side to feel for a temperature change that marks the gas level.
Inspect the Gas Hose and Connections
A kinked or pinched hose restricts gas flow and produces a weak flame. Uncoil the hose fully and make sure it's not trapped under the oven or stand. Also check that the connection at the regulator and the oven inlet is tight. A loose fitting can cause a gas leak and reduce pressure. If you smell gas, turn off the supply immediately and tighten the connection before relighting.
Reset the Gas Regulator
Propane regulators have a safety feature that shuts down flow if they detect a sudden surge—this can happen if you open the tank valve too quickly. To reset, turn off the oven and the tank valve, disconnect the regulator, wait 30 seconds, then reconnect. Slowly open the tank valve (turn it just a quarter to half turn) before lighting the oven. This slow opening lets the regulator re-pressurize without tripping.
Diagnosis: Low Flame in Your Gozney Oven
- Symptom: Flame is noticeably smaller than usual, takes longer to heat the oven, or won't reach cooking temperature. This is not normal operation. Do not keep cooking with a weak flame.
- Likely Cause: Gas supply issue: low propane, kinked hose, or tripped regulator. Less common: a dirty or damaged burner. Start with the simplest fix—check the tank and hose.
- Corrective Action: 1. Swap or refill the propane tank. 2. Unkink or replace the hose. 3. Slowly open the tank valve to reset the regulator. 4. If none work, inspect the burner for damage. After each step, test the flame. If it improves, you're done.
- Stop or Choose Another Option: If the flame remains low after all gas-supply checks, the burner itself may be faulty. Do not attempt to modify or repair the burner assembly yourself. Order a replacement burner (such as the Roccbox Gas Burner 30) and install it per the manual, or contact Gozney support.
When to Replace the Burner
- Roccbox Gas Burner 30: US/CA Roccbox Gas burner with hose and 30mbar screw fit regulator to fit a standard US portable propane gas tank. This part is included with the original product as standard. Purchase of additional spare parts should only be required if original part is lost or damaged. If your burner is physically damaged, corroded, or the orifice is clogged beyond cleaning, replacing it with the correct OEM part restores safe, reliable flame performance. This spare is identical to the original and includes the hose and regulator, so you don't need to piece together components.
