Thermopile
Thermocouple
BURNER FLAME
The flames from the burner should be visually checked
as soon as the heater is installed and periodically during
normal operation. In normal operation, at full rate, and
after operating for about 15 to 30 minutes, the flame
should be yellow and slightly taller than the rear log. See
Figure 61.
If the flame is blue and only in the center, turn off unit
and let cool. After unit is cool, remove logs and check to
make sure rock wool is placed correctly. Replace logs.
NOTE: The type of installation, vent system
configuration, and wind effects may cause the
flame patterns to vary.

mocouple, and the other reaching to the main burner..
