Flame Color and Behavior

Your stove is designed for maximum heating efficiency. Therefore, upon
lighting of the main burner the flames will be semitransparent or "bluish."
After 10-20 minutes of operation, the logs will heat up and the flames will
become a yellow/orange color.
Adjusting the stove to cause the flames to turn orange sooner may result
in poor combustion, sooting and a hazardous situation. See the drawing
to the right showing proper flame appearance.
When testing for proper operation - If an optional thermostat is installed
adjust it to its highest temperature setting. Visually determine that main
burner gas is burning properly: i.e., no floating, lifting or flashback. Ad-
just the primary air shutter(s) as required. Check for proper main burner
operation at both high and low flame.
