BURNER TUBE VENTURI ADJUSTMENT GUIDELINES
VENTURI ADJUSTMENT
Open venturi setting slightly
Close venturi setting slightly
Back (main) burner venturi adjustment handle is attached to underside of control board. Access through lower grill opening. Loosen wing
nuts, adjust as necessary, pulling handle forward to open, pushing backwards to close. Tighten wing nuts.
TO ADJUST BACK (MAIN) BURNER VENTURI:
WARNING
To avoid property damage or personal injury, allow fireplace time to cool before making any adjustments.
NOTE
If soot is present, check log positioning before adjusting burner venturi. Logs must not block burner ports.
IMPORTANT
SLIGHT ADJUSTMENTS TO BURNER VENTURI OPENING 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:
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.
WARNING
Burner tube adjustable venturi positioning should only be performed by a qualified professional service technician.
