INTRODUCTION

General Information

The LSO-43 fireplace is a traditional wood burning radiant heat system. The LSO-43-H comes with Herringbone styled refractory. These fireplaces come with standard bar grates, air inlet and optional decorative glass doors.

The fireplace is intended to be installed outside of the home. It could be installed against the outside wall of the house, or as a freestanding fireplace on the porch, patio, or simply located in the yard (see Figure 2 ).

The Outdoor Fireplace must be enclosed. To prevent impact damage to the outside of the fireplace. Build an outside enclosure out of standard building materials, being careful to maintain the minimum air clearances specified in these Installation Instructions.

When installing the fireplace as a freestanding unit on your porch, patio or backyard, it must also be enclosed to prevent impact damage to the fireplace. However, the enclosure must now be finished on all four (4) sides. The exterior of the enclosure may be finished in a textured plywood, a wood clapboard siding, brick, or a cultured stone. Vinyl siding is not recommended for use on the front of the fireplace due to the heat the unit produces. This can cause the vinyl siding to deteriorate.
