side of boiler.
The conduit from the housing
points in direction of the burner.

coming from the control is
routed to the burner. The wires
contained inside the conduit are
wired to the burner. Depending
on the model of burner, there
may be plug-in interconnections
or hard-wired connections to
the terminal strip located inside
of the burner.
3 Gas train wiring comes from the
burner housing. Check with
supplied equipment to verify if
gas train wiring is factory wired
or field wired.

IMPORTANT
Refer to the correct wiring
diagrams when wiring the control
to burner. Do not make any
connections without the proper
documentation.
IMPORTANT
The length of the conduit is
designed to allow for the burner or
boiler door to be opened when
burner is wired. Do not shorten
conduit without ensuring proper
access for service.
