(609mm) is required from that equipment.
FOR ALL OVENS: A 24‑inch (609mm) 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 13feet
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 NFPA96 latest
edition. In addition, to be in compliance with the NFPA 54
Section10.3.5.2, 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 2800CFM 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 8inches inside the canopy as shown.
2. The capture velocity across the lower edge of the
canopy is to be 50FPM 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 3feet from the
perimeter of the hood to keep them from affecting the
oven.

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" (762mm)
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" (762mm) 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.
