FLAME APPEARANCE
Flames from the pilot, front and rear burner should be
visually checked as soon as the heater is installed.
In addition, periodically check the flames visually during
operation.
CHECK THE PILOT FLAME
The pilot flame must always be present when the
heater is in operation.
It should just touch the top of the
thermocouple tip for natural gas. Refer to
Figure 20
for
correct pilot flame.
If the pilot flame does not touch the thermocouple, then
the main burner cannot function reliably. Refer to
Figure
21
for incorrect shape of pilot flame.
CHECK THE BURNER FLAME
In normal operation, at full rate after 15 minutes, the flames
should appear as shown in Figure 22.
