Is it Normal for Ventless Gas Fireplace to Smell?

The odor is one of the most serious drawbacks of a ventless gas fireplace. But don’t be concerned; it’s completely normal. During its first use, it usually burns off the factory paint and dust that’s accumulated and thus causes this smell.

Why does a Ventless Gas Fireplace Smell?

There are several reasons for this, but the most common one is that a ventless appliance requires room air to operate, any bi-products in the air, such as harsh deodorants, dog hair, paint fumes, and new carpet, will be drawn into the fireplace and burned thus emitting the smell.

Seasonal accumulation of dust can also cause an odor problem when you burn your gas logs for the first time each season.
