Step 2. Once the replace is placed on the platform, ensure there is access to install the vent pipe, and inline power vent module if applicable
and the gas line. Note the gas line connection location and room to provide a gas service shut-off valve; according to local gas codes. Before
fastening in place line up the front face and rear face of the replace (top and botttom), Figure 2a. then secure in place with 1/4" wood screws.
Step 1. You will need to construct a platform in the framing for the replace to sit on. To determine how high to build the platform you must
determine the how high you would like the bottom edge of your glass viewing area to be. The bottom edge of the glass sits 15 1/8" above the
top of the platform. Please note: The top of the platform may not exceed 24" in a room with 8' ceilings.
