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.
WARNING: BURNER TUBE ADJUSTABLE VENTURI POSITIONING SHOULD ONLY BE PERFORMED BY A QUALIFIED PROFESSIONAL
SERVICE TECHNICIAN.

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.
TO ADJUST VENTURI:
1. Remove cast door and glass frame assemblies. Refer to page 9.
2. Remove log set.
3. Remove burner assembly. Refer to page 18.
4. Loosen screw on burner venturi and adjust as necessary. Tighten screw.
5. Reinstall all components previously removed.
6. Light fireplace and wait 15 minutes before determining if any further adjustments are needed.

SEASONAL HEAT DUMP

This fireplace has been manufactured with an adjustable heat dump outlet inside firebox (at top). This allows infinite control over the
amount of heat emitted into the living area without affecting flame appearance.
CAUTION: If fireplace has been in operation allow ample time to cool before adjusting heat outlet opening or use appropriate protection to
prevent serious burns.
ATTENTION INSTALLER: Please install this fireplace with heat dump in closed position.
TO ADJUST: Remove cast iron door and glass frame assembly, adjust heat dump as desired, re-install glass frame and cast iron door
assembly.
