However, if you prefer, we can have your new gas log system delivered directly to the your address prior to installation. 


What is a Vented Gas Log System?


A vented gas log system is typically installed when the customer is more interested in aesthetics by seeing a fire that closer resembles a real wood burning fire than in producing heat for the living space.


A vented gas log system, as with a wood burning fire, is less efficient than an unvented gas log system as there is less heat produced, more soot created, less water vapor and increased amounts of carbon monoxide. 


Since a vented gas log system creates, as with a wood burning fire, a greater volume of undesirable byproducts, a vented gas log system also requires venting to the outside of your home or office to ensure safe operation of the system.  This is accomplished by natural draft (Class B) venting or by direct venting.


A vented gas log system utilizing natural draft venting can be installed into your existing fireplace which has been inspected by our technicians and determined to be in safe and good working condition.    If your chimney and/or firebox are not deemed suitable for safe operation of a typical wood burning fire then, it will not be safe for a vented gas log system.  Should your chimney require cleaning and/or repairs, a qualified chimney cleaning company will need to clean and make any repairs necessary for the safe operation of the fireplace.  Only after the fireplace and chimney are deemed to be safe can a vented gas log system be installed.


In the case of direct venting, the damper to your existing fireplace is closed off to the chimney and a new direct venting system, which directs byproducts of combustion (heat, soot, water vapor, carbon monoxide) out of your home or office, is installed.  The direct venting system also allows fresh air, which is necessary for combustion to occur, to enter the fireplace from the outside of the home or office.  


Is a Vented Gas Log System Safe?


Yes.   In the case of natural or direct venting, the fireplace and chimney must be inspected and approved by a qualified chimney cleaning and inspection company.  Once it has been deemed safe for a wood burning fire, the fireplace and chimney is considered safe for a vented gas log system.  Since carbon monoxide is vented to the outside of the living space, an Oxygen Depleting Sensor (ODS) is not required for a vented gas log system.


Some Common Sense Safety Tips.


Treat a vented gas log system with the same care and caution as you would for a wood burning fire.


Since all gas log systems, vented or unvented, do have an open flame and generate heat, do not place items such as newspaper, cloth, chemicals or any other combustible materials near the heat source.  The glass fireplace doors must be in the full open position during operation of your gas log system.


Never leave your gas logs burning while unattended.  While there is a great temptation to leave your gas log system burning while you are sleeping in an effort to provide extra heat to your home, please be reminded that your vented gas log system is not intended to replace your central heating system.


In homes or businesses where there are not plenty of open spaces, it's a good idea to open a window slightly while the gas logs are burning in order to allow more fresh air to enter the room.  In order to have combustion there are three requirements. (1) Ignition Source (electric starter switch); (2) Fuel Source (natural or propane gas); and (3) Oxygen (air in the room).  The combustion and venting process creates a negative air flow which will ever so gradually draw air (oxygen) out of the room.  That's why in closed living spaces it's wise to allow plenty of air to enter the area where the gas log system is being operated.


Don't assume that 'bigger is better.' For best air quality, the gas fireplace unit you install should be approved for the size of the room it will be used in.


To ensure that you are taking every precaution to ensure good air quality in your home or business, it's a good idea to install a carbon monoxide detector on each level of the building regardless of what type of gas burning appliance you might have. They are an inexpensive way to put your mind at ease about the air quality inside your home or office.
