Measuring your Fireplace for Gas Logs

When searching for the right size of gas fireplace logs, your fireplace should be measured carefully. Unlike outdoor fire pits, fire logs that merely fit into the cavity of your gas fireplace won't neccessarily function properly, and some gas log applications won't work at all if your fireplace is sized at an incorrect ratio. Save yourself some time and measure your fireplace first, before you set your heart on an any particular gas logs application.

Due to the operation of different units and their own unique features (pilot lights, remote controls, etc.) there are many different formulas for the necessary space and air flow requirements inside the cavity of your fireplace. Be sure you check the manufacturer's specification sheets of your gas fireplace model for the requirements for the space you will need to operate them.

Generally, you will need four separate measurements:

* Height of your fireplace cavity from top to bottom
* Depth of your fireplace cavity, (back to front)
* Width at the front of the fireplace cavity opening (left to right)
* Width at the back of the fireplace cavity, at the back wall (left to right)
* If you choose a vent-free application, you will also need to know how high your mantle is from the top of your fireplace cavity**

All measurements should be taken from inside the fireplace (don't leave the end of the measuring tape outside of the cavity). For depth and width dimensions, measure from the floor of your fireplace. Height dimensions should be taken 6"-8" inside the cavity, near the center of the chimney if you have one. This will be the approximate location of your gas logs. Once you have your measurements written down, consult your fireplace specification sheet for details on the best sizes of logs for optimum functionality.

**If your mantle is combustible you will need a fireplace hood.
