2.Remove gas line cover plate located on either side of fireplace and pull out insu- lation from gas line conduit sleeve. Save insulation for reuse.

3.Run a 1/2" black iron gas line into fire- place through rear at gas line conduit sleeve (if using a raised platform, add height). Provide sufficient gas line into fireplace chamber for fitting connection (see Figure 22).
