⚠️Safety Warning

All gas operations must be performed ONLY by a licensed contractor specialized in gas appliances. Gas work can be dangerous if done incorrectly.

Warranty Information

  • The warranty is completely free.
  • The warranty is valid for 1 year.
  • Coverage is valid only if the burner is shipped directly to Forno Classico for evaluation and possible repair.
  • Before shipping, it is mandatory to complete all troubleshooting procedures listed below.
  • The warranty applies only if all checks have been performed correctly.
  • If we find damage that is not our responsibility, the repair will not be covered under warranty.
  • No individual parts are shipped for free. The complete burner will be repaired and returned at no cost during the 1‑year warranty period.
  • This warranty applies only to the oven burner.

1. Confirm the main gas supply is open

  • Ensure the main gas valve feeding the oven is fully open.

2. Purge air from the gas line

  • Air inside the gas pipe must be released. This may take several minutes before only gas is flowing.

3. Check for spark at the pilot assembly

  • Verify that a strong spark is present to ignite the pilot flame.

4. Vacuum the burner area

  • The burner is located inside the oven.
  • Vacuum around and inside the burner to remove ash, dust, or debris.
  • Ash buildup can block airflow or interfere with the pilot flame.

IMPORTANT:

  • The oven must be completely OFF, including the pilot light.
  • Cleaning the burner area will shut off the pilot — this is normal.
  • After cleaning, relight the pilot following the standard ignition procedure.

5. Inspect the thermocouple
Ensure the thermocouple is:

  • Clean
  • Free of debris
  • Not damaged
  • Properly aligned

It must sit directly in the pilot flame.


6. Check for bent or pinched pilot tubing

  • Inspect underneath the oven to ensure the pilot gas tube is not bent or restricted.

7. Verify correct gas pressure

  • Natural Gas: 7 inches W.C.
  • Propane (LP): 11 inches W.C.

Incorrect pressure can cause the pilot to light but not stay on.

8. If the burner still does not work

  • Proceed to Step 2 or Step 3.

This is the recommended option and the only option covered by warranty.
