1. Venturi handle is attached to top of valve bracket (under firebox).

2. Adjust by pulling lever down slightly and sliding in either direction. Adjusting handle to far left closes venturi completely, while

adjusting to far right opens venturi completely. Normally the ideal setting lies somewhere between these two points.

3. Light fireplace. Wait at least 15 minutes before determining if any further adjustments are necessary.

FLAME APPEARANCE:

Flame appearance is affected by several factors including altitude, venting configuration and fuel quality. Although the venturi setting has

been factory set, adjustments may be necessary for optimal performance and visual aesthetics.

When fireplace is first lit, the flames will be blue. Flames will gradually turn yellowish-orange during first 15 minutes of operation. If

flames remain blue, or become dark orange with evidence of sooting (black tips), the burner tube venturi may need adjustment.
