Before you buy Gas logs read this
Before you buy Gas logs there are a few things to consider. One... are the Gas logs vented or vent free? Two...are there any allergies? Now that being said...i will explain the differences between the two types of Gas logs for your fireplace.
Vented Gas logs are gas logs that require the damper to remain in the open position when they are being burned. They look more realistic in my opinion as well. The downside of the vented logs is they do not produce the amount of heat that vent free logs provide. Gas logs can burn either natural gas or propane. Propane gas typically will provide more heat due to a hotter flame.
Vent free gas logs do not require the damper to be open when burning but, I recommend leaving the damper open at least one inch to allow the fumes to escape. I know..i know..they are 99.9% efficient..yea right! So was your car when you first bought it, and now it smokes a little when you crank it up. This is the reason i say leave the damper open a little. The amount of heat that will be lost is minimal to the peace of mind it provides.
Now the next thing i want to talk about is allergies. If you have any upper respiratory allergies, or asthma, you may want to reconsider getting gas logs. It will aggravate any problems you may have. I am a Chimney Sweep in South Carolina for over 25 years, and have seen all kinds of problems with the use of gas logs. I don't mean to sound as though i am bashing gas logs, that is not the case. I just want people to be aware of the problems that may occur. Also, make sure you have a chimney cap on your chimney because rain will come down the flue, and can ruin the gas logs. The main reason you need a chimney cap is to keep the rain out so mold spores won't form and cause even more problems.
OK, now the next thing i want to tell you is to invest in a carbon monoxide detector. It is a small price to pay for peace of mind. Although gas logs have oxygen depletion systems on them, i just like the added insurance.
I hope all of this info has helped, and if you have any questions i would be glad to help you. And don't forget....its good luck to shake hands with a sweep.
