3. RECEIVING

Read the notice on the outside carton regarding damage in transit. "CONCEALED DAMAGE", damage
discovered after opening the crate(s), MUST be reported immediately to the carrier. The carrier will perform
an inspection of the damage and furnish forms for the consignee's claim against the carrier. Retain ALL
packaging material - including outer carton, until the inspection has been completed.

Proper and secure storage facilities should be arranged for the conveyor oven(s) if necessary to protect it
from outdoor or damp conditions at all times prior to installation.

5

4. LOCATION AND MINIMUM CLEARANCES

Adequate air space must be provided for the proper venting of the rear exhaust air and provision made for
venting of cooking vapors. The Conveyor Oven must be installed in a well-ventilated area.
NOTE: Attached rear rubber bumpers must not be removed and can contact a rear wall if present.

Conveyor Ovens can be installed with "ZERO" clearances (back and sides) from combustible and non­combustible materials. (Rear rubber bumpers are the “Zero” clearance points on the back of the unit.) See
rating plate attached to the control box door panel.

The Conveyor Oven is intended for countertop mounting if mounted on the 4" legs provided. The Oven is
NOT approved for mounting on any floor. Keep the area around your conveyor oven free and clear of all
combustible materials.

5. INSTALLATION

In MASSACHUSETTS: All gas products must be installed by a “Massachusetts” licensed plumber or gas

fitter. Ventilation hoods must be installed in accordance with NFPA-96, current edition, with interlocks as
described in that standard.

Place the conveyor oven and parts as close to the area of final installation before uncrating. Your conveyor
oven is packed sitting on its bottom. Leave it this way until unpacked. The pallet may be left under the
conveyor oven for convenience in further handling. Unpack carefully to avoid damage to the unit. If
concealed damage is discovered, follow the instructions detailed in Section 1 above.

DO NOT LIFT EXCESSIVE WEIGHT

A. Legs are shipped unattached. Make sure each leg is attached and tightened before placing the

conveyor oven in place. Each leg is adjustable to accommodate variations in the mounting surface.

B. Using sufficient help (2 or more people), lift the conveyor oven upward and place on the countertop

surface. Lift the conveyor oven by gripping the bottom of the unit. THE FOLLOWING ITEMS ARE
NOT TO BE USED AS LIFTING "HANDLES": Side-mounted control boxes (2), front door, the
conveyor belt assembly, the rear fan housing assembly.

C. THE CONVEYOR BELT ASSEMBLY IS MOUNTED BACKWARDS FOR SHIPPING. THE

CONVEYOR BELT ASSEMBLY MUST BE REMOVED AND REVERSED PRIOR TO OPERATION.
See Section 9a, b for further instructions.

D. Position the conveyor oven in its final location, maintaining the minimum clearances specified in

Section 4 above.

E. Remove all loose parts and packages from the interior of the conveyor oven. The conveyor oven

has (4) air-directing "plenum fingers" in the interior cooking chamber. Check these items for proper
mounting. For further information on removal and mounting of interior panels, see Section 13,
cleaning.

6. STACKING

Your conveyor oven(s) can be
stacked up to (3) high. Each
unit is built exactly the same,
so it does not matter in which
order they are stacked. For
stacking of (2) units, remove
the legs from the second
(upper) unit prior to mounting
on top of the bottom unit. For
stacking of (3) units, it is
preferable to use a "stacking
kit", which allows all conveyor
ovens to be supported by an
external framework, such as a
table, with each conveyor
oven having all legs removed.

"CAUTION: If you use a multiple stack
assembly, remember that each oven has
its own power disconnect. Make sure
ALL main switches are OFF before any
cleaning or maintenance is performed.”

1. Remove two bottom screws from the top oven rear panel.

2. Remove two top screws from the bottom oven rear panel.

3. Install the right and left stacking brackets as shown in above diagram.

4. Reinstall the four removed screws.

When
stacking,
remove
legs from
upper unit.

Use
Stacking
Brackets
to secure
ovens
together.

When stacking,
align “Dimpled
Foot” of upper
unit into
matching
“Dimple” of
bottom unit.

7. ELECTRICAL CONNECTIONS

General Instructions

a) Model 1828G ovens are supplied with a flexible power cord and plug.

b) Make sure the electrical supply corresponds with that specified on the rating plate (see section 15).
c) Wiring diagrams are located in the Installation/Operating Instructions.
d) When installed, the unit must be electrically grounded in accordance with the local codes and/or the

latest edition of the national Electrical Code ANSI/NFPA No. 70 in the USA or Canadian Electrical
Code, CSA Standard C22.1, Part 1 in Canada.

8. GAS CONNECTIONS

The 1828G conveyor oven can be ordered either as Natural Gas or Liquid Propane Gas.

A) Only a qualified gas appliance installer should make gas connections.

B) The 1828G is supplied with a ½” NPT inlet pipe only. The installer must supply an approved

external gas pressure regulator to limit the inlet gas to the following pressure settings:

!
!

C) The installer must also supply a separate shut-off valve between the gas supply and the

appliance gas regulator.

D) If a flexible gas supply line is used, it must connected as shown in the diagram below. The

flexible connection must allow for movement without causing links in the hose. A sufficient
restraining device must also be attached to any portable mounting device to prevent the
hose from becoming overextended.

9. SYSTEM CHECK

A)

Insure that the conveyor belt assembly is installed correctly, with the drive-shaft pin fitting firmly into

the coupling that protrudes from the Power Control Box gearmotor output shaft. Visually check that

the belt is flat and paralleltothecountertopsurface. Ifthebeltisnotparallel to the countertop, it may
be necessary to re-align the gearmotor output shaft to the conveyor belt drive shaft pin. Follow this

procedure:

DISCONNECT THE POWER SUPPLY BEFORE SERVICING COMPONENTS INSIDE

1.

EITHER OF THE CONTROL BOXES. SERIOUS INJURY, INCLUDING DEATH, MAY
OCCURIFCONTACT IS MADE TOINCOMINGPOWER.

2. Re-aligning the coupling/driven-shaft pin requiresopeningthePower Control Box door.

3. Insertahex-headnut-drivertool to loosen the (4) screws that fastenthegearmotortothebox
sidepanel.

4. Re-align the coupling to the conveyor belt drive shaft pin. If this is done properly, the driven-
shaftpinwill fit snuggly into theslotofthe gearmotor coupling.

5. When alignment is correct, re-tighten the (4) screws at the gearmotor before closing the
door.

B)

The conveyor belt is capable of traveling either Left-to-Right (standard), or Right-to-Left (optional).
Direction of travel is determined by looking at the conveyor oven from the front of the unit. Direction
of travel is controlled by a Reversing Switch that is located inside the control box containing the
gearmotor. If the directionoftravelneeds to be reversed,followthisprocedure:
