Step 6: Electrical Requirements, Connection & Grounding
Dual Fuel models must be connected to the power supply utilizing one of the following methods. For all methods
of connection, the length of the cord or conduit/wiring must allow the unit to be slid completely out of the cabinet
without having to unplug or disconnect the unit from the power supply. Recommended minimum free length of
cord or conduit is four feet. Electrical installations and grounding must be in accordance with all local codes and
ordinances, and/or the National Electric Code, as applicable.
4-CONDUCTOR CORD -
NORMALLY, A UNIT MUST
BE CONNECTED TO THE
POWER SUPPLY WITH A
3-POLE, 4-CONDUCTOR
CORD KIT RATED 125/
250 VOLTS, 50 AMPERES,
AND MARKED FOR USE
WITH RANGES. The cord
kit must be attached to the
range junction box with astrain
relief which will fit a 1" diam-
eter hole. If not already
equipped, the cord must have
1/4" faston closed-loop lugs
attached to the free ends of
the individual conductors, pref-
erably soldered in place.
PERMANENT CONNECTION
(HARD WIRING)- Units may
be hard wired to the power
supply. The installer must
provide approved flexible
aluminum conduit, 3/4" trade
size, maximum 6 feet long.
Locate the junction box on the
rear of the unit and remove

strap up. Refer to Fig. 10. The
conduit must be installed to
the junction box using an

Wiring for the unit is to be
brought into the junction box
through the conduit. The ends
of the wiring must have
1/4" faston closed-loop lugs
attached, preferably soldered
in place. Make the connec-
tions to the terminal block pro-
vided. Secure the ground lead
to the junction box with the
screw previously used to se-
cure the ground strap. Refer
to Fig. 11. The free end of the
conduit must be connected to
a junction box provided in the
gas and electrical supply zone,
as shown in Figure 3A on Page
