Figure 16 shows a correct pilot ﬂame pattern. The correct

ﬂame will be blue and will extend beyond the thermopile.

The ﬂame will surround the thermopile just below the tip.

A slight yellow ﬂame may occur where the pilot ﬂame and

main burner ﬂame meet. Figure 17 shows an incorrect pilot

ﬂame pattern. The incorrect pilot ﬂame is not touching the

thermopile. This will cause the thermopile to cool. When the

thermopile cools, the heater will shut down.
If pilot ﬂame pattern is incorrect, as shown in Figure 17

• See Troubleshooting, page 21.

from the logs and the ﬁrebox area. An extra-soft brush should be

used on the logs as they are extremely fragile; a vacuum cleaner

may be used on the ﬁrebox. If at any time the logs cannot be

removed or installed without forcing, the cause must be found.

The logs must never be forced.
CAUTION: The ceramic logs are durable when handled and

installed properly. However, they are delicate and may be damaged

easily if not handled with care. Handling damage to the ceramic

logs is not covered by warranty.
DO NOT HANDLE LOGS WHILE THEY ARE HOT. ALLOW

PLENTY OF TIME FOR THE APPLIANCE TO COOL

COMPLETELY BEFORE HANDLING.

PLEASE NOTE

It is normal for appliances fabricated of steel to give off

some expansion and/or contraction noised during the start

up or cool down cycle. Similar noises are found with your

furnace heat exchanger or car engine.
