(609mm) is required from that equipment.

FOR ALL OVENS: A 24‑inch (609mm) clearance at the rear of

the oven must be obtainable for service access.

FOR PERMANENTLY INSTALLED OVENS: A permanently

installed (unmovable) oven requires a minimum of 13feet

clearance on the right hand side to allow for conveyor

removal, cleaning, and servicing.

NOTE: Do not install this (these) oven(s) in any area with an

ambient temperature in excess of 95°F/35°C. Doing so will

cause damage to the unit.

VENTILATION REQUIREMENTS

A VENT IS REQUIRED: Local codes prevail. These are the

“authority having jurisdiction” as stated by the NATIONAL

FIRE PROTECTION ASSOCIATION, INC. in NFPA96 latest

edition. In addition, to be in compliance with the NFPA 54

Section10.3.5.2, this unit must be installed with a

ventilation hood interlock that prevents the unit from

operating when the ventilation hood is off. For further

ventilation information, see below.

Ventilation Guidelines

A ventilation hood is required to remove heat and cooking

odors. For gas ovens, a ventilation hood is also required to

remove the products of combustion. The hood and HVAC

installation must meet local codes to gain approval by

the authority having jurisdiction. Requirements may vary

throughout the country depending on the location by city,

county, and state. Obtain information from the authority

having jurisdiction to determine the requirements for your

installation. (NOTE: This oven is considered as “Light Duty

for Baking” when evaluated for code vent requirements.)

Obtain information and review copies of codes or

documents that will be used to inspect and approve your

installation. Your ventilation hood supplier and HVAC

contractor should be contacted to provide guidance. A

properly engineered and installed ventilation hood and

HVAC system will expedite approval and reduce oven

maintenance costs. Proper ventilation is the oven owner’s

responsibility.

The ventilation hood must operate in harmony with

the building HVAC system. It typically requires between

1600 and 2800CFM exhaust or more with 70% make‑

up air. (The “Efficiency” of various hood designs makes it

necessary to specify such a wide range of ventilator CFM.)

Make up air must be supplied by either a hood design or

the HVAC system. This will vary with hoods from various

manufacturers.

,

Caution

Prevent airflow through the cooking tunnel. Air must

NOT be directed onto the oven front or at side of cooking

area or rear of oven.

Ventilation System

NOTE: These ovens are considered “Light Duty for Baking”

when evaluated for code vent requirements.

This information is shown as a guideline for ventilation.

1. Dimensions shown are for ovens without extension

shelves. The outside end of the conveyor frame must be

a minimum of 8inches inside the canopy as shown.

2. The capture velocity across the lower edge of the

canopy is to be 50FPM at sides and front.

3. Use filters at rear exhaust area of hood, as shown.

4. At start‑up, the CO level must be checked around the

oven space under the canopy.

5. This level must be <10ppm.

6. The ovens are to be centered in the canopy space left‑

to‑right and front‑to‑back if possible.

7. A 6‑inch space at rear of oven is recommended for

utilities.

8. Recommend 70% make‑up air provided outside of the

canopy through perf metal diffusers directed straight

down — not at the oven; located at front, sides or both.

9. Room air diffusers must not be directed onto the oven

and should be positioned a minimum of 3feet from the

perimeter of the hood to keep them from affecting the

oven.

2. A package containing the stand and top.

It is recommended that you have a material‑handling

device available to unload.

DO NOT LIFT EXCESSIVE WEIGHT!

IF THERE IS APPARENT DAMAGE:

UNITED STATES AND CANADA: Arrangements should

be made to file a claim against the carrier, as Interstate

Commerce Regulations require that the consignee initiate

a claim.

ALL SHIPMENTS TO OTHER COUTRIES: Freight terms will be

developed and extended on an individual basis.

Proper and secure storage facilities should be arranged for

the oven(s). If necessary, protect it from outdoor or damp

conditions at all times before installation.

UNCRATING

When you have all the crates unloaded, open the crates and

remove the plastic covers. Inspect at once for concealed

damage. If anything appears to be damaged, contact the

appropriate persons immediately to file a damage claim.

After completing this inspection, finish unpacking the oven

and all other components. Be sure to remove the cardboard

from the plenum shroud. Move all components inside near

the area where they will be assembled in the order in which

they will be assembled.

THE OVEN WILL CLEAR THROUGH A 30" (762mm)

DOORWAY BY USING THE FOLLOWING PROCEDURE:

• Remove conveyor; see “Weekly Cleaning” section for

instructions. (Some units may have conveyor packed

separately.)

• Remove thumb screws and baffle from the left side of the

oven.

Caution

Do not lift the ovens using the control enclosure. Lift

from the main oven cavity only. Damage may occur to

the controls of the oven if lifted by the control enclosure.

Uncrate the unit. Remove all finger components, the

conveyor, and the front door, along with all four door

knobs. The unit can then either be placed on the left side

(the side opposite to the control box), or preferably on the

front (door) side, on a four wheel moving dolly, and it will

clear a 30" (762mm) doorway.”

Manual Gas Valve Installation

When installing the gas valve that is supplied with the oven

it is our suggestion that an elbow be placed on the oven

pipe first. This will allow the flexible hose to be attached in a

downward direction, eliminating possible stress to the hose.
