FINALIZING THE INSTALLATION

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.
