Vent-free gas heating appliance operates without a chimney, flue or vent, so you can install a system just about anywhere without making a hole in the wall or roof. Vent-free gas products include space heaters, stoves, fireplaces, fireplace inserts, and gas logs.
Buy a Safe Product
Consumers should consult a full-service retailer when choosing the right vent-free gas product for their particular needs and have the appliance professionally installed and serviced. Every vent-free gas heating equipment sold in the U.S. today, regardless of the size, shape, appearance, heat output, or price, undergoes rigorous safety testing.
Today vent-free heating appliances are required to be equipped with an oxygen detection safety sensor (ODS). The ODS is similar to circuit breaker and automatically shuts off the unit in the unlikely situation that carbon monoxide is elevating and there is oxygen depleting in the vicinity of the unit (regardless of the CO source). Any attempt to override, modify, or tamper with the unit, will cause the ODS to shut off the gas supply and disarm the ignition system to prevent the appliance from operating.
Keep Vent-Free Heaters Away from Combustibles
Because vent-free gas products are a heating appliance, it is very important to distance combustibles from surrounding furniture, drapes, adjacent walls, human activity, etc.
Perform Routine Cleaning and Maintenance
As with all appliances, routine cleaning and maintenance according to manufacturer’s instructions is advised. When cleaning a vent-free hearth product, it is critical that the logs be returned to the precise position relative to the burners as required by the manufacturer to avoid the possibility of soot build up.
