Installation Section 2
SPACING REQUIREMENTS
,Caution
Oven must be operated on an approved base only.
The oven must have 6 inches (152 mm) of clearance from
combustible surfaces. In case other equipment is located
on the right side of oven, a minimum clearance of 24 inches
(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 4'
(1219mm) 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
For standard ovens, a ventilation hood is required to
remove heat and cooking odors. Alternatively, optional
electric “ventless”models are available which incorporate
a catalyst to limit the emission of grease laden air to below
5mg/m3. Ventless ovens have been tested in accordance
with UL710B & EPA-202 and are listed by UL to the KNLZ
category. Ventless ovens should only be used for reheating
purposes and should not be used to cook raw animal
proteins, doing so may cause the appliance to exceed
allowable grease laden air limits and/or cause damage to
the catalyst. Ventless oven models can be identified by the
“-V-”suffix as part of their model number, refer to the spec
sheet for more details. When permitted by local code(s) and
used with appropriate food products, Lincoln“ventless”
ovens are not required to be installed under a ventilation
hood. 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. 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.
Lincoln 1100 ventless ovens equipped with a catalyst(s) are
approved for ventless operation while single or double-
stacked only.
The ventilation hood must operate in harmony with the
building HVAC system. It typically requires between 750
and 2500 CFM (1274 and 4248 m3/hour) exhaust. (The
“Efficiency” of various hood designs makes it necessary
to specify such a wide range of ventilator flow.) Make
up air must be supplied by either a hood design or the
HVAC system. This will vary with hoods from various
manufacturers.
Notice
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.
