Lava Rock and Ember Material

1.For all models, place lava rock along sides and front of firebox bottom in areas that are visible. It is not necessary to use all lava rock provided.

NOTICE: Do not put lava rock on or under burner. Placing lava rock on burner could cause performance problems.

2.Pull ember material apart into pieces no larger than a dime. Place loosely and directly onto exposed section of front burner and along space between burner and grate prongs. These will cre- ate glowing ember appearance as flame touches ember material. Do not block air slots by using too much ember material in one area. It is not necessary to use all ember material provided.

3.When lava rock and ember material are in place, close and latch glass door and secure louvers in place.

WARNING: The glass door must be securely in place before operating fireplace. Do not oper- ate fireplace if glass is missing or broken.

DECORATIVE FACING

Any noncombustible material may be used as fac- ing (glass, tile, brick, etc.) as long as the proper clearances are observed (see Clearances to Com- bustibles, page 4). Louvered openings must not be obstructed and upper and lower panels must remain accessible for service. Use only heat-re- sistant, noncombustible mortar or adhesive when securing decorative facing materials.
