Frequently Asked Questions about Natural Gas Ventless Fireplaces

Can I convert a propane fireplace to natural gas?

Most ventless units are factory-set for a specific fuel and are NOT convertible. Always purchase the specific natural gas ventless fireplace model you need.

Does a natural gas ventless fireplace smell?

When properly installed, these units are virtually odorless. A slight "new" smell may occur during the first few hours of operation as factory finishes cure.

Do I need a chimney for a natural gas ventless unit?

No, these units are designed to burn fuel completely, requiring no chimney or flue.

Can I install these in a bedroom?

Most codes allow natural gas ventless units in bedrooms if they are rated at 10,000 BTUs or less.

Will it work during a power outage?

Yes. Most models use a pilot light or battery ignition system that does not require electricity to provide heat.

Is professional installation required?

Yes. A licensed gas plumber must connect the unit to your natural gas line to ensure safety and warranty coverage.
