An ultraviolet flame sensing device, or U.V. scanner, must be used

with a 3/4" N.P.T. swivel connector. The scanner and connector can

be used in three possible locations: two mounting ports are located

near the gun assembly adjacent to the pilot which sight both pilot

and main flames, while a third mounting port on the side of the

combustor sights only the main flame. Flame detection methods

are affected by fuels and applications:

• For gas, light oil, or heavy oil with air atomization, locate a U.V.

scanner in one of the two mounting ports near the pilot to prove

pilot and main flames.

• For heavy oil with steam atomization, two scanners must be used.

Because atomizing steam absorbs ultraviolet light, a scanner

mounted near the pilot will only prove the pilot flame. Therefore,

a second scanner mounted on the combustor side is needed to

prove the main flame.

Note:

Due to the low U.V. content of oil flames, some U.V. scanner/

flame safety systems may have difficulty sighting oil flames at

high inputs. In these cases, a more sensitive U.V. detector may

be required or an infrared (I.R.) detector may be used.

Make sure that you connect the flame sensor of a burner to the

electrical circuit of the burner.

Danger:

If you connect the flame sensor of a burner to the

electrical circuit of the wrong burner, then you can

cause fires and explosion.

For detailed information on how to install and connect a U.V. scanner,

refer to:

• straight U.V. scanner; Bulletin/Instruction Manual 854

• 90° U.V. scanner; Bulletin/Instruction Manual 852

• self-check U.V. scanner; Bulletin/Instruction Manual 856.
