Carbon monoxide is a by-product of any burning process of any fuel. Ventless fireplaces are not an exception to this.

Since the ventless fireplace is ventless, there is no way for the by-products of combustion to be vented to the outside. This can cause some concern if the ventless fireplace is left on for more than 4 hours, or the manufacturers recommended time.

Another by-product of ventless fireplaces is water vapor. Water vapor is released when the heat from the flame touches the cooler air of the room. If you are using a ventless fireplace in a small area, you could possibly notice a buildup of humidity in that area.

With a greater concern about carbon monoxide safety, some manufacturers are putting a built-in carbon monoxide detector into the ventless fireplace. This should never be relied upon in the place of having your own carbon monoxide detector in your own home.

With any gas fired appliance, you really should have a good carbon monoxide detector in your home. Test it regularly, and follow the manufacturers directions for ventless fireplace safety as related to their specific product.

Ventless fireplaces can burn two types of fuel. They can burn either natural gas, or propane, or a newer style of fuel called “gel”. Most ventless fireplaces are generally decorative in nature. They generally don’t produce enough heat to be useful for heating large rooms or a whole house for example. However, ventless fireplaces can be used to effectively heat smaller rooms.

Ventless gel fireplaces are not used to heat, but are purely decorative. Since they use a small jar or container of a gel fuel as the fuel source, the flame is generally decorative from gel fireplaces.

As with any device that is fueled by either natural gas or propane, you should have a carbon monoxide detector in your home. This is important for ventless fireplace safety.
