CONTROL CIRCUITS
Burner firing stage may be controlled by either a 120V or 24V control system. The required controls must be connected to the
burner as described on the following pages.
120V CONTROL SYSTEM
First stage firing is controlled by a 120V operating control wired between terminals 3 and 4 on the terminal block. To control
second stage fire on demand only, a second 120V control must be wired between terminals 7 and 8 after removing the fac-
tory-installed jumper.
24V CONTROL SYSTEM
First Stage firing is controlled by a 24V operating control wired between terminals 3 and 4 on the terminal block. To control second
stage fire on demand only, a second 24V control must be wired between terminals 7 and 8 after removing the factory installed jumper.

the absence of local codes, with
the National Electrical Code ANSI/
NFPA 70-1990 and the CSA Elec-
trical Code.
