PILOT FLAME PATTERN
Figure 13
shows a correct pilot flame pattern. The correct flame
will be blue and will extend beyond the thermocouple/thermopile.
The flame will surround the thermocouple/thermopile just below
the tip. A slight yellow flame may occur where the pilot flame and
main burner flame meet.

MAIN BURNER FLAME PATTERN
The main burner flame will be yellow with a blue base.
Main Burner Flame Ignition and Extinction
When the main burner is ignited it will take a few seconds for the
full flame pattern to develop.
When the main burner is extinguished it will take a few seconds for
the flames to disappear. It is normal to have the flames burn down
near the rock wool, as the remaining gas is burned.
