INSTALLATION
Stacking the Ovens
Stacking kits must be requested upon purchase.
Remove all the plug buttons from the top of the lower oven.
Remove the stacking kit from the oven compartment of one oven and install the 1 1/4-
inch plastic bushing into the top of the lower oven.
Tip the top oven backwards and install two pins into the front leg holes of the top oven.
Route the wires 1 and 2 from the upper deck through the 1 ¼-inch knockout in the
bottom of the oven through the 1 ¼-inch knockout in the top of the bottom oven to the
main terminal block in the bottom oven. Refer to wiring diagram for proper phasing.
Lift the top oven and gently set on top of the lower oven so that the studs nest into the
holes of the lower oven.
If placing a range top onto the oven, see the installation section of the range top for
installation directions.
Electrical Connection
The electrical connection must be made in accordance with local codes or in the absence
of local codes with
NFPA No. 70 latest edition (in Canada use : CSA STD. C22.1 ).
The electrical service entrance is provided by a 1 1/4-inch knockout on the oven bottom.
A three pole terminal block is provided for connection.
INITIAL PREHEAT
Prior to putting any oven into full time operation at normal cooking temperatures, it
must be thoroughly dried out. Moisture absorption in the closed spaces, in the
insulation, and even inside the heating elements can cause future trouble if not
properly treated.
To “dry out” the oven, set the thermostat to 250
°
and turn on the power switch.
Allow the unit to cycle at least 15 minutes at this heat level. Reset the thermostat to
350
°
allow the same time. Reset the thermostat to 450
°
and allow the unit to maintain
the temperature for a minimum of 4 hours. More time may be required if the unit has
to operate in moist environment.
If the unit is out of use for three or more days, a one-hour preheat schedule should be
used, especially when exposed to high humidity and/or cool temperatures.
NOTICE:
During the first few hours of operation you may notice a
small amount of smoke coming from the oven, and a
faint odor from the smoke. This is normal for a new
range and will disappear after the first few hours of use.
