Fireplace construction

I am going to build a fireplace in the living room and equip it with a set of vent free gas logs. I want the fire place to look authentic so I plan on constructing it out of brick. I do not plan on building a chimney or anything other than a closed firebox inside. Is there any place on the net that has ideas on construction or plans that would help me in laying out the project?

I would like to suggest one thing first, you should call the local building authority first as these may not be acceptable and you will need a building permit for it.



Less involved installation
Potential to be installed in many places, BUT must follow room sizing requirements (typical unvented fireplace requires 96' x 20' room)
Very efficient in burning of gas, but uses heated room air for combustion


Air quality issues/health concerns
Typical sizing guidelines for an average fireplace size (30,000 BTU's) require a 96' x 20' room size - or 1,920 sq. ft. to safely accommodate unvented products
Illegal in many states and municipalities
A typical (unvented) natural gas stove or fireplace releases a gallon of water vapor every 2 to 3 hours of operation - potentially causing mildew issues*
May require more service to ensure dust, pet hair, and other chemicals are not interfering with the unit
For safety reasons cannot be run for extended periods of time - Maximum Use- 4 to 5 Hours per day.
Requires permanent fixed opening to the outside for proper room ventilation

You may want to consider your choices but do a web search for plans.

Good Luck!

I have researched the pro's and cons of vent free gas logs. The unit will not be used as a primary or secondary heating system, just a functional decorative addition to the formal living room. The log set I'm looking at has an oxygen depletion system and adjustable flame height. It will see limited use and should pose no more problems than our gas oven and stove top that is used daily. I live in a township that has no enforced building requirements or permits. I'm Just looking for some plans or ideas as to constructing the fireplace.
