Frequently asked questions

Are ventless gas fireplaces safe?

They certainly can be. Just buy a reliable unit from a trusted brand, install it correctly, and use it properly for total peace of mind. Many models have oxygen depletion sensors (ODS) that automatically shut off the flame if oxygen levels fall too low.

Where do the fumes go in a ventless gas fireplace?

The small amount of byproducts produced is vented directly into the room since these units burn gas ultra-efficiently. That’s why proper room size and ventilation are important when choosing your model. 

What states have banned ventless gas fireplaces?

California and Massachusetts are two states that have restricted/banned indoor vent-free gas fireplaces due to air quality concerns. Always check local building codes before installation.

Do you need a chimney for a ventless gas fireplace?

No chimney or flue is required, and that’s usually the biggest selling point for these types of modern fireplaces. You can install them virtually anywhere with a gas line and adequate ventilation.

What are the disadvantages of a ventless fireplace?

Added indoor humidity and local code restrictions. They also can’t be used in tightly sealed or very small rooms without proper ventilation.

How long can you safely run a vent-free gas fireplace?

It’s best to use ventless fireplaces as supplemental heat and run them for a few hours at a time. Always follow the manufacturer’s safety guidelines for operation time.

Which is better, ventless or vented gas fireplace?

It all depends on your space and your goals. Ventless is best if you want maximum heat efficiency and easy installation. However, a direct vent fireplace could be better if you want to vent outdoors and minimize moisture buildup.

Do these fireplaces look different than direct vent fireplaces?

Not at all. Many ventless models, such as the Monessen Artisan Linear, look identical to vented systems with real flames, LED lighting, and contemporary glass or log media.

Should I be worried about humidity with this fireplace?

Ventless fireplaces produce small amounts of water vapor as a byproduct. This can actually be quite pleasant in the right conditions - but light ventilation is recommended in very humid climates or tightly sealed spaces.
