Why do some gas fireplaces need to be vented?
Traditional gas fireplaces, like their wood-burning cousins, require an exhaust flue (vent) to remove harmful fumes from the home. When possible, an existing chimney is used to run a new flue, but in a home without a chimney, the high cost to install venting can sideline the project permanently.
Can you vent gas fireplace into chimney?
A gas stove can be vented through an existing chimney, whether it is a manufactured or masonry chimney. To ensure proper venting, however, a liner must first be installed in the chimney. In a B-vent system, a substantial amount of heat is lost through the chimney.
Are gas fireplaces bad for your health?
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.
How do you vent a gas fireplace without a chimney?
If you don’t have a chimney, a natural vent system can also use a pipe venting system, which is typically installed through the roof. Here, you can get around having to use a brick and mortar chimney to rid the home of fumes and use a pipe system instead.
Fireplaces can’t share the same flue but can be run in the same chimney with their own flue liners. It got that way as the fireplace sucked air from the interior of the house for combustion air for the fire and pulled heated air from the rooms to assist the draft of the flue gasses up and out the chimney.
Does a gas fireplace give off carbon monoxide?
Yes, gas fireplaces are one potential cause of carbon monoxide poisoning. An improperly maintained or ventilated gas fireplace can create incomplete combustion, creating carbon monoxide, and causing this toxic gas to linger—putting those inside at risk of carbon monoxide poisoning.
Will a gas fireplace work in a power outage?
Gas & wood fireplaces will continue to work safely during a power outage. These fireplaces do not require electricity for venting and can be used safely during a power outage.
The whole of a shared stack can only be removed if both owners are in agreement – if it is on account of defect the cost will generally be split but if it is being done as part of improvement works to one property the owner benefitting from those works will generally carry the cost.
