Place log #6 (left log) onto left pin of front log (#2) and the smooth surface of rear log (#3). Make sure it is seated properly.

Place log #7 onto right pin of top log (#5). Make sure it is seated properly.

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

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

Close glass door, lock door latches and secure louvers in place.

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

BURNER FLAME ADJUSTMENT

The burner flame adjustment (shutter opening) is factory preset (for natural gas) to the proper air-to-gas ratio. This ratio results in an even and clean burning flame across the burner (see figure 19).

If adjustment is necessary, you can restore the proper flame setting by loosening the air shutter screw and rotating the air shutter until proper setting is achieved (see figure 20). The correct shutter opening is listed below.

DECORATIVE FACING

Any non-combustible material may be used as facing (glass, tile, brick etc.) as long as the proper clearances are observed (refer to section on clearances on page 3). Louvered openings must not be obstructed and upper and lower panels must remain accessible for service. Use only heat-resistant, non- combustible mortar or adhesive when securing decorative facing materials.

OPERATING GUIDELINES

When lit for the first time, the fireplace may emit a slight odor for about 16 to 24 hours. This is normal and is due to the “curing” of the logs and the “burn-in” of internal paint and lubricant used in the manufacturing process.

Keep compartments, logs, burners and area surrounding the logs clean by vacuuming and brushing at least twice a year or as necessary.

Turn off gas and remote wall switch before servicing appliance. Any safety screen or guard removed for servicing the fireplace must be replaced prior to operation. Have a qualified agency periodically inspect the vent system at the start of each heating season for any obstruction, which hinder its normal operation. Never obstruct the flow of combustion and ventilation air. Keep the front of the fireplace clear of all obstacles and materials.
