Ventless gas fireplace design options are on fire!

Virtually ever household in America is built with a fireplace. Some households are built with traditional wood-burning fireplaces with an accompanying chimney, and others are built with gas fireplaces which use an outside ventilation system. A gas log fireplace provides the image, heat, and other characteristics of a traditional fireplace, but without the smoke and creosote build up. There are two types of gas log fireplaces: the first type requires outdoor ventilation, and the second requires a gas log burner set with special safety features for ventless gas fireplace usage. A ventless gas fireplace is designed with a special valve to control the flames, heat output and limit the release of carbon monoxide. Both fireplaces have different advantages.

A ventless gas fireplace can be moved around the house easily. Gas fireplaces produce less sparks (negating the need for a fire screen or spark arresting curtain), do not cause creosote build up (which makes them very easy to maintain and clean compared to a wood burning fireplace) and are built to accommodate different décor because various logs, ship sets, decorative pine cones, rocks and shapes can always be added to affect the flame pattern and design of the log set. Also, gas fireplaces produce the same amount of warmth as a traditional fireplace controlled with the fire flue.

Each part of a gas fireplace has significance in protecting the customer and making realistic flames and logs.  Gas fireplace burners are designed based on the final flame pattern goal.  Some gas fireplace burners are made to produce larger flames burning tall and others are designed to spread the gas flame exhibiting less tall flames while accentuating bright burning embers below the logs.  Ventless gas fireplace burners have very specific port-holes for flames to minimize contact with ceramic logs.

All gas fireplaces should be used in conjunction with a thermocouple.  The thermocouple acts as a safety system to prevent the release of gas if the fire is not burning. In order for the gas valve to open the thermocouple must be hot from the pilot flame. If there is no pilot flame the fireplace will not light because the valve stays closed.  When lighting a standing pilot the valve is pressed in an held in an open position until the thermocouple is hot enough to produce a small magnetic charge which hold the valve open as long as continuous heat keeps the magnetic charge live.  If the flame blows out the thermocouple releases the magnetic charge and the valve closes to stop the flow of gas.

The gas fireplace valve is controlled either manually like a barbecue grill or with a remote control that is designed like a hand-held transmitter, thermostatic control or a wall switch to control variable flame height and gas flow.  Vented gas logs and ventless gas fireplaces use different types of valves because vent free burners have a limited BTU output.  While the definition of a British Thermal Unit refers to actual heat, barbecue grills and gas log manufacturers use the term to refer to the amount of gas moving through the valve and burning.  Heat measurements based on fuel consumption are denotively measured

 

Lastly, the fireplace has special gas logs. These gas logs are made to resemble real wood logs of all kinds. Also, the gas logs will often cost less than traditional firewood. Lastly, the logs produce less smoke and only consume about 50,000 to 90,000 BTU/HR of gas, which costs about forty to eighty cents per hour. BTU stands for British thermal unit. A BTU is approximately the amount needed to heat one pound of water.

In conclusion, gas fireplaces are taking the place of traditional fireplaces for many reasons. The first is the fact that gas fireplaces do not require traditional firewood and can be lit with the touch of a button. Secondly, gas fireplaces are easy to move around when redesigning a room. Lastly, it costs next to nothing in terms of gas.
