FIELD WIRING

(either right or left), flexible conduit must be used for
the last 5 to 6 feet before the burner. Do not use rigid
conduit right up to the burner! A wiring diagram is
provided with all burners. A separate page titled “Con-
nection Diagram” is included, which rec om mends and
illustrates the number of conduits for the field wiring,
including the number of wires for each con duit.
It is recommended that the ame scan-
ner wires are run in a separate conduit
and not in multi-wire ca bles. Maximum
line length for UV monitoring is 97 feet
(30 meters). For de tails re fer to the ame
