Figure 36 shows a correct pilot ﬂame pattern. The correct ﬂame will be blue and will extend beyond the thermocouple and thermopile.

The ﬂame will surround the thermocouple and thermopile just below the tip. A slight yellow ﬂame may occur where the pilot ﬂame and

main burner ﬂame meet. Figure 37 shows an incorrect pilot ﬂame pattern. The incorrect pilot ﬂame is not touching the thermocouple

or thermopile. This will cause the thermocouple or thermopile to cool. When the thermocouple cools, the heater will shut down.

If pilot ﬂame pattern is incorrect, as shown in Figure 37

• See Troubleshooting, page 32.

Figure 38 shows a correct main burner ﬂame pattern. Figure 39

shows an incorrect main burner ﬂame pattern.

If main burner ﬂame pattern is incorrect, as shown in Figure 39

• See Troubleshooting, page 32.

Cleaning and Maintenance / Main Burner

Warning: Turn off heater and let cool before cleaning.

After use, cleaning of the main burner may be required for the

proper ﬂame. The main burner may be cleaned by applying air

pressure to the ports on the main burner.
