INSTALLING BASIC OVEN
The basic oven must be installed on legs or be mounted on a modular stand. Installations on concrete
bases or other supports restricting air circulation underneath the oven is not advisable and may void
the warranty.
Ovens Mounted on Casters
Separate instructions for installing casters to the oven are included with the casters.
Note: If the oven is installed on casters and is moved for any reason, it is recommended that the oven
be releveled front to back and side to side for even baking.
Assembling the Legs to the Single Oven
The 4" (10 cm) or 6" (15 cm) legs are packed inside the oven during shipment and must be installed
on the bottom of the oven. Position the oven on its left side, taking care not to scratch or damage it.
Thread each of the four leg assemblies into the holes provided on the bottom corners of the oven.
Carefully raise the oven to its normal upright position.
Assembling the Chimney to the Single Oven
Remove the oven chimney from inside the oven cavity and use the
screws provided to fasten the chimney to the top rear of the oven
(Fig. 1). The flanges on the chimney are to be positioned over the
top cover.

Assembling the Oven to the Stand
Unpack the oven and stand. Position oven on its back, taking care not
to scratch or damage it. Install the two locating studs (included in the
stand carton) into the screw plates on the underside of the oven (Fig. 2).
Attach each of the four leg assemblies to the bottom of the stand with the
24 bolts and lockwashers (6 per leg). If casters are used instead of legs,
put fixed casters in rear and swivel casters in front. Mount the oven on
top of the stand.
Assembling Stacked Ovens
Determine which oven will be on the bottom and place it on its left side,
being careful to avoid scratching the finish. Install the four 163/4"
(42.5 cm) legs, using the 24 bolts and lockwashers provided (6 per leg).
Place lower oven (with legs) on floor. Remove the two 7/16" (1.1 cm) knockouts on each side of the top
cover and the 13/32" (2.8 cm) knockout on the right side of the top cover. Move this oven to the
installation position.
Install the two locating studs (included in leg stack set) into the screw plates on the underside of the
top oven (Fig. 2) and remove the 13/32" (2.8 cm) knockout that will line up with the one removed from
the bottom oven. Carefully place the top oven in position above the bottom oven.
LEVELING
Once the oven is in its permanent position, place a carpenter's level on the oven rack. If the oven is
installed on legs, turn adjustable feet in or out to level oven front-to-back and side-to-side. If the oven
is installed on casters, loosen set screws and turn casters in or out to level oven front-to-back and side-
to-side. Retighten set screws after leveling.
