- Electrical wiring.
- Framing and finishing details.
- Whether optional accessories - devices such as a

1. Selecting Fireplace Locations

This fireplace may be used as a room divider, installed
along a wall, across a corner or used in an exterior chase.
See Figure 2.2.
Locating the fireplace in a basement should be avoided.
Locating near frequently opened doors, central heat
outlets or returns, or other locations of considerable air
movement can affect the performance.
