avoid cross threading.
• Align the leg plate holes in each leg with those in the
corners of the oven bottom and secure using two 5/
16"-18 x 1/2" bolts. Tighten all bolts firmly. Repeat
this procedure for all legs.
• Raise the oven up on its legs.
Level the oven by turning the adjustable feet in or out as
needed.
Caster Installation
• Casters are available as an option for both the single
and double oven sections.
• The installation of casters requires the removal of
the adjustable feet from the legs. This is done by
placing the bit of a large screwdriver against the lip
of the foot and rapping the screwdriver to drive the
foot out of the leg. The caster is then inserted fully
into the opening where the foot came out and the
locking nut tightened to expand the compression
sleeve of the caster.
NOTE: The casters with locking brakes are best
mounted on the front side of the oven for easier access.
NOTE: If you plan to use casters and flexible fuel gas
connectors, a fixed restraint of the proper length must
be incorporated to secure the oven to a non-movable
surface to eliminate strain on the connector. If the oven
is removed from its normal position, the restraint must
then be reattached when returned.
Installation of the Vent
• Ovens ordered for installation under a powered
canopy exhaust hood should have the flue guard in
place. This item can be installed by placing it over
the flue opening, making sure that it does not
obstruct the flue, and attaching it with the screws
provided.
• Ovens ordered for installation in a location other than
under a powered canopy exhaust hood are supplied
with a drafthood & drafthood collar. This device
mounts to the top of the upper oven section by
attaching the drafthood adapter to the flue opening
with the screws provided, the drafthood is then
mounted on top of the adapter. The flue pipe is
attached vertically to the drafthood.
H. Adjustments Associated with Installation
Each oven section and all its component parts have been
tested thoroughly and inspected before your oven was
shipped from the factory. However, it is sometimes
necessary to further test or adjust the oven once it has been
installed. Such adjustments are the responsibility of the
Dealer or Installer. These types of adjustments are not
considered defects, rather a normal and routine part of the
proper installation of the equipment.
These adjustments include but are not limited to:
• Adjustments and recalibration of the thermostat
• Adjustment to the doors.
• Burner or pilot adjustment.
• Adjustments to the gas pressure regulator.
• Leveling, and tightening of fasteners.
No installation should be considered complete without
proper inspection and, if necessary, any adjustments by
qualified service or installation personnel.
It is also important not to obstruct the natural flow of
combustion and ventilation air if the oven is to operate
properly. This oven should not be installed on a curb base
or sealed to the wall. Either condition can restrict the flow
of air to the combustion compartment or prevent proper
ventilation of the blower motor. The blower motor has a
thermal protection device that will trip because of
excessive ambient temperature at the back of the oven.
This condition should be corrected immediately to avoid
damaging the oven permanently.
Before making any connections to the oven, check the
ratings plate to be sure the oven specifications concur with
the type of gas and voltage to be supplied to the oven.
The rating plate is located behind the lowered lower front
panel. To access, loosen the four screws below the doors,
and pull panel outward.
The plate bearing the oven's serial number is attached to
the underside of the upper ledge above the control panel.
I. Double Sections
• Secure the short legs to the bottom of the lower
section as described in previous section.
• Casters are installed by the method described for
single section ovens. Previous section.
• Place upper section on top of lower section and align
all edges of the ovens.
• Locate securing clips and align with holes on rear
frames of oven section, install three screws each as
provided and tighten.
• At the rear of the oven, install the flue connector by
sliding it up through the flue vent opening in the top
of the oven and over the upper flue vent. Push it
flush with the back of the oven then slide it down
over the lower flue vent. Attach with screws
provided.
• Install flue guard or drafthood adapter, drafthood and
drafthood collar to upper section.
