Symptoms

One or more of the following may occur:

• Burning plastic smell
• Chemical odor
• Strong “new appliance” smell
• Odor strongest during first startup

Cause

This condition is normal for a new stove.

During initial operation, the stove burns off:

• Manufacturing residues
• Protective coatings
• Adhesives
• Residual oils
• Materials associated with the manufacturing process

This is commonly called the burn-off process or break-in period.

Recommended Burn-Off Procedure

To help reduce odor during initial use:

1. Operate the stove on High Heat (Level 5).
2. Run the stove in a well-ventilated area.

Recommended ventilation:

• Open windows
• Increase room airflow
• Use fans if needed

Some customers choose to perform the first burn outdoors when practical.

Expected Duration

The odor usually decreases after the first few burns.

Many customers report the smell dissipating within 1–2 days after completing the burn-off process.

Important Notes

A temporary odor during initial operation is expected and normal.

The smell should gradually decrease with use.

The burn-off process does not indicate damage or malfunction.
