sembly, turn off the gas to the unit and remove the
logs exposing the burner and pilot assembly. Clean
all foreign materials from top of burner. Check to
make sure that the burner orifice is clean.
Visually inspect the pilot periodically. Brush or blow

flame patterns with Figure 13.
To obtain proper operation, it is imperative that the pilot
and main burner flame characteristics are steady, not
lifting or floating. Typically, the top 3/8-inch (9.5m) at
the pilot generator should be engulfed in the pilot flame
(Figure 12).
