FINALIZING THE INSTALLATION

FLAME APPEARANCE:

Flame appearance is affected by several factors including altitude, venting configuration and fuel quality. Although the venturi settings
have 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 venturis may need adjustment.
WARNING: BURNER TUBE ADJUSTABLE VENTURI POSITIONING SHOULD ONLY BE PERFORMED BY A QUALIFIED
PROFESSIONAL SERVICE TECHNICIAN.
WARNING: TO AVOID PROPERTY DAMAGE OR PERSONAL INJURY, ALLOW FIREPLACE AMPLE TIME TO COOL
BEFORE MAKING ANY ADJUSTMENTS.
