IMPORTANT
SLIGHT ADJUSTM ENTS TO BURNER VENTURI OP ENING CREATE DRAMATIC RESULTS. ADJUST AT SLIGHT
INCREMENTS UNTIL DESIRED LOOK IS ACHIEVED. ALWAYS BURN FIREPLACE FOR AT LEAST 15 MINUTES
AND ALLOW TIME TO COOL BEFORE MAKING ANY FURTHER ADJUSTMENTS.
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.
