4 Common Questions about Gas Logs

4 Common Questions about Gas Logs

Aren’t these cool temperatures refreshing!!   If you are outside in the evenings, you have probably caught the aroma of smoke in the air from a neighbor’s wood-burning fireplace.   But with the beauty and warmth of these fires also come the tasks of cutting firewood (or purchasing it $$$) and disposing of the ashes.   Because of the work involved, many people are now choosing gas logs over wood.   I thought this would be a good time to address some of the most frequently asked questions regarding gas logs.

What is that foul smell coming from my gas logs?    If you can’t burn your gas logs because they emit a terrible odor, you have logs manufactured in China.  The only way to correct this problem is to replace your logs.    If you find yourself in this predicament and need to replace your logs, please be careful not to purchase logs made in China.  At Shaw Building Supply, we sell Monessen Hearth Gas Logs and Fireboxes made in Paris, Kentucky.

If I choose vent-free gas logs, is there a danger of asphyxiation from the fumes?  An unventilated gas-fired heater uses air (oxygen) from the room in which it is installed.   The heater is fitted with a  specially designed safety pilot which senses the amount of oxygen available in the room.    If the oxygen level begins to drop below a satisfactory level, the pilot will automatically shut the gas log heater off.

What is the difference between vented and non-vented gas logs?  Vented gas logs are primarily used for applications where the homeowner prefers the most realistic look possible from an imitation log set.  This look is achieved because the flame actually touches the logs.  Over time, the logs become dark from carbon buildup.  Most of the heat produced from vented gas logs is lost up the chimney whereas 98% of the heat from non-vented logs is introduced back into the home.     The gas code refers to vented gas logs as a decorative appliance and to non-vented gas logs as a secondary or auxiliary space heater.

If I am setting a gas log set into an existing wood-burning  fireplace with chimney, why do I need to have my chimney inspected before installation?  This can be explained in one word – creosote.  Creosote is an extremely combustible substance and if wood has been burned in your fireplace, you probably have a creosote buildup on the inside of your chimney.  The cool creosote is hardened but when heated, it becomes liquid.  The liquid creosote will run down the chimney and drip onto your gas logs.  This creates a real fire hazard but it can also ruin your gas heater and logs.   All gas log manufacturers recommend the chimney be inspected by a qualified licensed chimney sweep prior to installation of logs.

If you are in the market for gas logs or have a problem with  your existing logs, please give me a call.   If I can’t answer your question, I probably know someone who can!
