In general, running a gas fireplace too long can potentially increase the risk of both fire and fumes. The duration of time that a fireplace can be left on will depend on the type of unit.
Some fireplaces can be left running on a continuous basis, while other models are designed to operate for only a few hours at a time. If you own a fireplace that is fully-vented and equipped with a sealed glass front, this type of unit can operate continuously. On the flip side, if your fireplace unit is vent-free and equipped with front doors that can open — this unit should only operate for a maximum of three hours at a time. There are three main types of gas fireplaces found in residential homes.
Direct vents eliminate that risk. These units have no flue, so they can be installed anywhere—even hung on a wall like a flat-screen TV. They're up to 99 percent efficient because all their heat stays in the room—as do all the pollutants. Because of concerns about air quality, indoor units are fine-tuned to burn extra clean, and their heat output is limited to 40, Btus. They have an oxygen-depletion sensor that automatically shuts them off if a room's oxygen level dips below 18 percent Even so, vent-free units are banned in California and some U.
Allows you to dial in just the amount of heat you need, from a whisper of a flame to a roaring fire. The best units adjust down to 30 percent of full output. Pulls indoor air into the space behind the firebox and pumps hot air out, heating a room in a hurry. A fireplace above a bathtub? Yup, you can do it with gas. This modern double-sided unit also shows its flames in the adjacent bedroom. Not only is a fire romantic, you can use a remote to adjust flame size and room temperature without lifting your head from the pillow.
Cut the evening chill and add a flickering glow to your surroundings with a low-profile gas fireplace; no chimney needed. Outdoors, vent-free units have no Btu restrictions or oxygen-depletion sensors. In this perennially favored fireplace location, gas creates looks you could never get before, such as this linear wall of fire burning up through a bed of glass. Direct-vent gas fireplaces are right at home in below-grade rec rooms, where wood-burning fires can smoke due to poor draft.
In the winters I run gas burners in the fireplace all day and unattended. A standing pilot is always on, always using a small amount of gas to run constantly unless the gas is physically turned off. Choosing to turn on a gas fireplace or a gas furnace really depends on what you want to accomplish. Usually it is more fuel efficient to have the fireplace on because it doesn't lose any heat traveling through ductwork, but that also means the heat is localized and won't warm the entirety of a large house.
Here are good reasons to turn off your gas fireplace pilot in the summer : When your pilot light remains on, a small amount of heat is generated. The glass doors on your gas fireplace remain warm to the touch. When your pilot light is off , you save money and help to conserve energy. Gas fireplaces are generally considered cleaner than traditional wood-burning fireplaces , but they can also pollute indoor air quality if not properly vented.
Toxic gasses emitted include deadly carbon monoxide and nitrogen dioxide -- a gas particularly harmful to those with asthma. All vent-free logs are firmly attached to a U-shaped burner and cannot be moved.
Follow the gas line from beneath the logs to where it disappears in the wall or floor. If the gas is merely contained by a simple gas line, then the logs are vent free.
Turn on the fireplace. If you get dust in the pilot assembly and the pilot needs to be cleaned out, it produces a "lazy" flame, which will be disturbed by the draught of the main burners. The flame lifts away from the thermocouple and causes the temperature on the tip of the thermocouple to drop. This, in turn , makes the gas valve shut off. Carbon monoxide gas : You can 't see it, smell it, or taste it — but it can kill you , silently and with little warning.
Excess Heat Can Damage The chimney can heat up to a point where it can crack. If your wood fireplace feels hotter than usual, lower the heat emission before damage occurs. However, if you have a chimney, you could crack it open and let the heat out during the party to limit the weird smell.
People either love or hate these fireplaces. So it would be wise to get some opinions from the others living with you. Having a direct vent fireplace is having your cake and eating it too. One pipe brings in air from the outside to burn, and an exhaust pipe sends the fumes and all the other bad stuff out! The only effect it has on the home is warming it. Of course. When set on low, the fire stays pretty, and it provides exactly the amount of heat you want. You can put it on a thermostat set it for 70 and let it do its own thing!
Heat, decoration, efficiency, power outages? How often will it be used, and how many hours a day will it operate? How often will it be used?
