(Figure 12). A single “beep” will
confirm reception of the command.
FLAME COLOR AND BEHAVIOR
This appliance is designed for maximum heating efficiency. Therefore, upon
lighting of the main burner, the flames will be semi-transparent or “bluish.”
After 10- 20 minutes of operation the logs will heat up and the flames will
become a yellow/ orange color.
Adjusting the appliance to cause the flames to turn orange sooner may result in
poor combustion, sooting and a hazardous situation. See (
Figure 13) 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. Adjust the primary air
shutter(s) as required. Check for proper main burner operation at both high and
low flame.
