5. Connect the green appliance wire to a
grounded wire in the junction box or to a
grounded cold water pipe.
6. If connecting to a grounded cold water
pipe, a separate copper grounding wire
(No. 10 minimum) must be connected to a
grounded cold water pipe by means of a
clamp and then to an external grounding
connector screw.
WARNINGS:
1. Do not ground the appliance
to a gas supply pipe or hot
water pipe.
2. Do not turn on power to the
appliance until the oven is
permanently grounded.
3. Grounded cold water pipe
must have metal continuity
to electrically ground and
must not be interrupted by
insulating materials. Any
insulating materials must be
jumped as shown in Figure 10
below with a length of No. 4
copper wire securely clamped

Mounting the Oven
WARNINGS:
1. Failure to install the mounting
screws may result in
movement or tipping of the
oven during use and personal

2. Do not block the oven air
exhaust located at the bottom
of the oven. Blocking the
intake may cause cabinet
damage and poor baking
performance.
