2. ADJUSTING THE PILOT FLAME
The­pilot­flame­should­envelope­3/8­to­½­in.­(10­to­13mm)­
of­the­tip­of­the­Spark/Flame­Sensor,­depicted­in­Figure­8.­
To­adjust­the­pilot­flame:­
a.­Remove­pilot­adjustment­cover­screw.­Refer­to­Figure­9.­
b.­Turn­inner­adjustment­screw­clockwise­to­decrease­or­
counterclockwise­to­increase­pilot­flame.­
c.­Always­replace­cover­screw­after­adjustment­and­tighten­
firmly­to­ensure­proper­operation.
3. MEANS OF PROVING ADEQUATE GROUNDING AREA
The­proper­flame-rod-to-ground-area­ratio­cannot­
always­be­determined­by­visual­examination­or­
physical­measurement.­A­positive­means­of­checking­
the­installation­is­the­measurement­of­the­flame­rod­
current­under­actual­firing­conditions.­It­is­definitely­
recommended­that­the­installer­measure­the­current­
flow­between­the­lead­of­the­flame­rod­unit­and­the­
terminal­in­the­control­terminal­board­(see­Figure­7).­
Measure­the­current­with­a­DC­Microammeter­or­equal.­
We­recommend­a­steady­output­of­0.9­microamperes­
or­more.­A­steady­flow­of­current­in­this­amount­under­
actual­firing­conditions­will­generally­indicate­adequate­
grounding­of­the­pilot­flame.
