of mounting holes in plenum. Drill or punch holes
for mounting screws.
2. Fasten the brackets in place with furnished
screws. Start the screws but do not tighten.

Tighten the screws securely.
3. Insert element tube through bracket, straighten
controller and fasten by tightening setscrew. Be sure
screw strikes tube frame and does not strike sensing
element.

WIRING
Disconnect power supply before beginning
installation to prevent electrical shock or equipment
damage.
All wiring must comply with local electrical codes and
ordinances or in the absence of local codes with the
National Electrical Code ANSI C1-1981-NFPA 70.
Follow burner or furnace manufacturer's instructions if
available; otherwise, see Fig. 10 and proceed as
follows.
The brass jumper is the breakaway type. It must be
removed when the limit is used in the low voltage
circuit. To remove jumper, break with a needlenose
pliers and remove completely, Once removed, it is
not replaceable. See Fig. 8 for location.
The slotted knockouts on the bottom of the case and
the strain relief bushing are provided to simplify the
installation procedure and to protect the wires.
1. To remove the slotted knockout(s), use a
needlenose pliers as shown in Fig. 5 and pull straight
down.
2. If cable is used, we recommend using a strain relief
bushing in the knockout (Fig. 6). Pass the wires through
bushing before connecting.
