INTRODUCTION

General

OV500G1-EE
rack and OV500G2-EE & OV500E2 rack ovens hold
two single racks or one double rack.

Oven features:

• Powered rack lift with high temperature bearings
and a clutch rotating system designed to stop the
rack in the event of a jam without damage to the
rotation motor or losing rack alignment.

• Digital programmable controller with optional
backup control, flush flooring, and field reversible
bake chamber door.

All of the information, illustrations and specifications
contained in this manual are based on the latest
product information available at the time of printing.

Heating

The rack oven reaches baking temperatures of 350°
in approximately 20 minutes; however, a 30 minute
preheat is recommended to fully heat the steam
generator.

Steaming System

Standard on all rack ovens, is a self-contained
spherical cast steam system providing excellent
steaming conditions.

& OV500E1 rack ovens hold one single

UNPACKING

Remove the crating from the oven exterior, check for
possible shipping damage. If the oven is found to be
damaged after unpacking, save the packaging
material and contact the carrier within 15 days of
delivery.

LOCATION

To reduce the risk of fire, the appliance is

to be installed on non-combustible surface only, with
no combustible material within 18 inches above the
appliance. The appliance is to be mounted on floors
of non-combustible construction with noncombustible
flooring and surface finish and with no combustible
material against the underside, or on non-combustible
slabs or arches having no combustible material
against the underside. Such construction shall in all
cases extend not less than 12 inches beyond the
equipment on all sides.

Oven not provided with a canopy hood, must be
installed under a ventilation hood.

The floor must be level with surrounding area with a
maximum slope of 1/8" per foot up to 3/4" maximum
in all directions. Floor anchors require a minimum 1"
thick solid floor substrate.

A level floor area must be prepared before assembling
oven. The floor area should be at least 104"D x 74"W
for double rack oven and 94"D x 57"W for single rack
oven, to accommodate the oven footprint and door
swing. Check the facilities floor area at the threshold
and door swing opening location to determine if
facilities floor will need to be reworked.

Do not obstruct the flow of combustion and ventilation
air. Keep the appliance area free and clear from
combustibles.

Make sure there is an adequate supply of make up air
in the room to allow for combustion.

The electrical diagram is located on the inside of the
heat exchanger compartment door.

NOTE: If the location has multiple ovens, keep the
serial numbered crates together.

Oven is UL/CSA Listed for zero clearance for back and
side
for plumbing rear drain connection.

Top of oven requires a minimum of 24" clearance for
servicing accessability.

TESTING THE GAS SUPPLY PIPING

When test pressures exceed 1/2 psig (14" W.C.)

material against the underside, or on non-combustible
slabs or arches having no combustible material
against the underside. Such construction shall in all
cases extend not less than 12 inches beyond the
equipment on all sides.

4. The floor must be of non-combustible material,
and must be level with surrounding area with a
maximum slope of 1/8" per foot up to 3/4"
maximum in all directions. Floor anchors require
a minimum 1" thick solid floor substrate.

5. Oven is UL/C-UL classified and CSA (AGA/CGA)
approved for 0" clearance on the side and rear

doorways prior to positioning sections for installation.

Prior to installing the oven, check facilities floor for being level within a maximum of 1/8" per foot up to 3/4" in all
directions using the laser level technique to determine if oven will need to be shimmed. Also check facilities floor
area at the threshold and door swing opening location to determine if facilities floor will need to be reworked.

OVEN SECTIONS

Remove all assemblies except oven sections from
skids prior to lifting oven sections. In some cases

sections assembled together.

NOTE: On split OV500 single rack ovens, remove the
rack lift/rotate assembly and center insulation cover
from the top of the oven prior to standing up.

1. Place the oven sections as close to the final
position as possible, allowing enough room to
work, with the sections positioned for lifting.

A. Check for ceiling clearance. The oven is

tallest when it is approximately 60 degrees
to the floor during the raising process. If
oven section has been turned on its narrow
side in order to navigate through a doorway,
turn the oven section back to the shipping
position prior to raising.

B. Remove the bottom hold down brackets

from both pallets, but do not remove oven
sections from pallets.

DO NOT remove the two top

brackets prior to lifting units.

2. Lift the oven sections upright, using the hoist
technique. Both oven sections should be as close
as possible, but not touching.

NOTE: Single rack ovens have a one piece floor. The
floor will need to be put into location with a bead of red
high temp silicone around the outer edge of floor
flange before oven sections are slid together. The right
front corner of oven will need to be lifted, to clear
flange on the floor (door jamb retainer) when installing
a one piece floor.

A.

Place a piece of paper at bottom hinge side
between door and door gasket.

Close oven door and slowly pull on paper.

B.

There should be just enough drag to hold
paper from falling. Repeat this procedure
around door every couple of feet. If door is
too tight on hinge side, loosen the hinges on
the door and adjust door outward, reverse if
to loose. For latch side adjustment, loosen
screws on ramp(s) and move ramp(s) in or
out.

C. After adjusting the ramps for proper gasket

seal, make sure rollers contact ramps at the
same time. To check this, push the door
closed until one roller lightly touches a ramp,
check to see where door edge aligns with
vertical lines on the ramp gauge. The door
edge should align with the same vertical line
on each ramp gauge.

4. To install latch arms:

A. Remove inner door handle cover.

B. Remove 3/8” bolt. DO NOT discard the tube,

bolt or washer.

C. Remove E-clip and pin. DO NOT discard the

E-clip or Pin.

D. Replace two latch arms with parts supplied.

Reassemble inner mechanism, making sure
linkage arms are located in the up position.
Re-attach inner door handle.

NOTE: For left hand hinge, bolt and arms must be
flipped and mounted to hole. place unused arms to
latch box and secure with 1/4-20 bolt.

D. If adjustment is required, move a ramp so

that both rollers contact the ramps at the
same time.

NOTE: Keep in mind the door gasket seal. Both
ramps need to be in correct location to equalize
pressure on rollers.

6. Repeat the process until desired results are
obtained or call Bakery Product Support.
