INSPECTING BURNERS CONTINUED BURNER FLAME PATTERN Figure 53 shows a correct burner ﬂame pattern. Figure 54 shows an incorrect burner ﬂame pattern. The incorrect burner ﬂame pattern shows sporadic, irregular ﬂame tipping. The ﬂame should not be dark or have an orange/reddish tinge. Note: When using the ﬁreplace the ﬁrst time, the ﬂame will be orange for approximately one hour until the log cures.
Page 29: Wiring Diagram
CLEANING AND MAINTENANCE Continued Clean the pilot assembly also. A yellow tip on the pilot ﬂame indicates dust and dirt in the pilot as- sembly. There is a small pilot air inlet hole about two inches from where the pilot ﬂame comes out of the pilot assembly (see Figures 56 or 57 depend- ing on model).
