Eclipse Bi-Flame v1.8, Instruction Manual 826, 05/03
29
Aim scanners at the third of the flame closest to the burner nozzle, as
shown at left. This is especially true for oil flames which typically have
less UV radiation in the outer flame. The scanner should view the in-
tersection of the pilot and main flames. When sighting scanners, please
consider the following:
1) Sight the scanner away from the ignition spark. Sighting the spark
or its reflections from burner internals can be misinterpreted as a
flame signal.
2) Do not allow the scanner to detect a pilot flame that is too small
to ignite the main burner.
3) Perform a minimum pilot test when installing or adjusting any pilot
or main burner system; see “Minimum Pilot Test” on page 30.
