19 - FINALIZING THE INSTALLATION
A. 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.
