Step 1
Learn the features of vent-free heating. Vent-free heaters are self-contained units, controlled manually or by the use of a thermostat that triggers ignition and gas flow according to room temperature.
-
Step 2
Adapt a 'green' attitude. A vent-free heater is environmentally sound because there is very little wasted fuel. In addition, a chimney is not a requirement, so this type of heater is less expensive to install in a home.
-
Step 3
Enjoy the ambiance without worry. Many vent-free heaters resemble wood-burning stoves or traditional fireplaces, offering the warm glow of a fire without the smoke and ashes.
-
Step 4
Operate your vent-free heater with safety in mind. Vent-free heaters manufactured in the United States are equipped with a pilot safety device that detects the level of oxygen in the room and shuts off the pilot light if there is an oxygen deficiency.
-
Step 5
Maintain a safe distance between the heater and other flammable objects. Manufacturer specifications for vent-free heating units detail the amount of free space required around the perimeter of the heater to prevent the combustion of nearby flammable materials. These specifications vary with the type and quality of the heater.
