Finalizing The Installation; Burner Tube Adjustment / Troubleshooting - kozy heat Thief River Falls-TRF 56701 Installation And Operation Manual

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. The flames will gradually turn yellowish-orange during the first 15 minutes of opera-
tion. If the flames remain blue or the flames become dark orange with evidence of sooting (black tips), the burner tube venturi may need
to be adjusted.
