OUTSIDE AIR KIT

INSTALLATION

The installation of the outside air kit must be installed during the rough framing of the fireplace due to the nature of its location. Outside combustion air can be accessed through an exterior wall or a vented crawl space (see Figure 13).

GAS LINE INSTALLATION CAUTION: Air inlet ducts must not terminate in attic space.

The maximum height for the air inlet above the platform of fireplace is a minimum of 3 feet below the chimney cap.

For further details on the installation of the outside air kit, please refer to the instructions included with the air kit.

2.Remove gas line cover plate on rear of fireplace and pull out insu- lation from gas line conduit sleeve, save insulation for reuse.

3.Run gas line into the fireplace through the rear at 111/4" from the floor and through gas line conduit sleeve (if using a raised platform, add height). Provide sufficient gas line into fireplace chamber for fitting connection (see Figure 15).

Note: Secure incoming gas line to wood framing to provide rigidity for threaded end.

4.Repack insulation around gas line and into sleeves openings. Seal any gaps between gas line and refractory knockout hole with refractory cement or commercial furnace cement. Install the decorative gas appliance or cap off gas line if desired.
