These gas burners are manufactured for use with 120 volt, 60 cycle, single-phase electric
current. The installation must comply and be grounded in accordance with the National Board
of Fire Underwriters and National Electric Code ANSI/NFPA No. 70-1987 (or the latest
addition). All applicable local codes should be followed as well.
Installation wiring should be wired through each limit control or interlock; follow the
wiring diagram for the control for details. Do not use the 24 Volt transformer found on the
burner to power other items in the heating system, such as thermostats, spill switches, etc. See
the sample wiring diagrams provided below:
Below are several wiring diagrams. Depending on the control system of the burner, the wiring
and sequence of operations will differ (see Fig. 6 and 7). Also included are some common
wiring diagrams for field wiring (Fig. 8 and 9). Wire the burner accordingly in compliance with
all applicable codes. For special controls, a separate control manual will be provided. Please
refer to these diagrams for further information.
