INTEGRAL RECIRCIRCULATING SYSTEM
Dear Mr. Pool:
In reply to your e-mail message received today, I offer the following.
Products in the KNLZ category (as well as KNKG) are evaluated to UL710B. It used to be that UL197
and supplement SB in UL197 was the standard that they were evaluated to. Basically, UL197 and
Supplement SB became UL710B. There is no more Supplement SB in UL197 (9th Ed.).
Any information and documentation involving UL Mark services are provided on behalf of Underwriters
Laboratories Inc. (UL) or any authorized licensee of UL.
Very truly yours,

Re: Fire and smoke containment
Dear Mr. Denny:
The TurboChef ovens have been extensively tested and conform to UL 923 and UL KNLZ
standards. The UL 923 standard is the electrical/product safety standard and the KNLZ is the low particulate matter
emissions standard to which we conform. While both standards address difference aspects of the oven, they both
have inherent overlap as it relates to grease/smoke/fire handling.
As it relates specifically to fire safety, UL 923 specifies:
Section 57 Cavity Fire Containment Test:
The performance of an appliance subjected to this test shall be considered
acceptable if all of the following conditions are met:
a) There is no emission of fire, flame, or molten metal outside the appliance nor glowing or ignition
of the cheesecloth, tissue paper, or wood surface;
b) The fuse rated 3 A does not open;
c) Following the test, the appliance complies with the requirements of Leakage Current, Section 33,
and Dielectric Voltage-Withstand Test, Section 39, as applicable to primary circuits; and
d) Following the test and following 10 c of operation (opening and closing the door), the
appliance complies with the requirements in 57.12. The radiation emission shall not xceed
5mW/cm2.
Test Method:
Section 57.2 requires that 4 potatoes each weighing between 150g and 200g be placed inside the
oven under test and cooked using full microwave power and hot air (if applicable) until the potatoes
catch fire. Note: The test must be repeated until it catches fire. During this test, pieces of tissue
paper and cheesecloth are placed above, below and around the product to ensure that the fire
and/or excessive heat generated is safely contained within the confines of the appliance.
As it relates to grease handling, UL KNLZ specifies:
UL KNLZ Guide Information Excerpt:
“These appliances have been evaluated for the limit of 5 mg/m3 for the emission of grease-laden
air to the room ambient in accordance with the recommendations of the National Fire Protection
Association Standard for Ventilation Control and Fire Protection of Commercial Cooking
Operations, NFPA 96, using the EPA-202 test method prescribed for cooking appliances provided
with integral recirculating air systems.”
C:\Windows\Temp\Rar$DI00.000\Fire smoke and grease statement v2_11.doc
Download from Www.Somanuals.com. All Manuals Search And Download.
Page 9.2
Test Method:
The UL KNLZ category requires that products must have less than 5.0 mg/m3 of particulate matter
emissions during 8 continuous hours of cooking a “worst case” food product as measured by EPA
202. Note: Our products were tested using full-fat pepperoni pizzas.
As it pertains specifically to smoke: Smoke typically consists of visible grease particulate that escapes from a product
during operation. Our ovens utilize a recirculating airpath that is catalytic scrubbed, thus the airborne grease is
combusted as it crosses our catalyst. Given this, under typical/normal operating conditions, our product does not emit
smoke.
If you have any issues or specific questions regarding the above, please contact me directly.

RE: Exemption from Mechanical Exhaust Ventilation for
TurboChef Model NGC Rapid Cook Oven
Dear Ms. Sender:
Thank you for your application of April 26, 2004, for a review of the TurboChef Model
NGC Rapid Cook Oven for exemption from the mechanical exhaust ventilation
requirements of Section 114140 of the California Uniform Retail Food Facilities Law
(CURFFL). Specifically, you have requested an exemption to allow unventilated NGC
Rapid Cook Ovens to be installed and operated at various Subway locations throughout
California.
You have provided documentation and I have verified that the TurboChef Model NGC
Rapid Cook Oven has been evaluated and listed by UL for conformance with ANSI/NSF
Standard 4.
Under the provisions of CURFFL Section 114140, the Department may exempt heating
and cooking equipment that does not produce toxic gases, grease, smoke, or heat
when properly installed and operated as recommended by the manufacturer. Based on
the information and documentation you have provided, the TurboChef Model NGC
Rapid Cook Oven is granted LIMITED exemption from mechanical exhaust ventilation
under the following conditions:
1. Unless approval is granted by the local enforcement agency, there shall be no
more than one unventilated oven in operation at each Subway location.
2. No other heating or cooking appliances subject to mechanical ventilation
requirements may be operated without mechanical ventilation in the food
facility, unless permission to operate more than one unventilated appliance is
granted by the local enforcement agency.

3. The oven shall not be used for cooking meats, poultry, fish, or other foods
that may produce grease laden vapors. Such use will require that mechanical
ventilation be installed over the unit.
4. The oven must be operated and installed in a well-ventilated area approved
for food preparation.
5. The oven must be installed, maintained, operated, and serviced according to
the specifications of the manufacturer and local codes.
6. This exemption shall not be deemed to supersede any local fire or building
code requirements.
This exemption shall be in effect until revoked. However, should any local enforcement
agent find that the operation of the TurboChef Model NGC Rapid Cook Oven without
mechanical ventilation creates a sanitation or safety problem, the local enforcement
agent may require the unit to be used only with mechanical ventilation. These problems
may include, but are not limited to, problems of installation, use, maintenance, cleaning
or other site specific considerations which exceed the above limitations or pose a
discernable health or safety hazard.
This letter may be used as evidence of the evaluation of the TurboChef Model NGC
Rapid Cook Oven. However, it is not to be construed as an endorsement of the subject
item and may not be used for advertising or promotional purposes.
If you have any questions you may call me at (916) 650-6617.

TurboChef Tornado Oven Model NCG
Please distribute the attached information to sanitarians on your staff who work in the Food Program.
Attached please find IARC Guidance Document #04-04V regarding the new TurboChef Tornado
Microwave/Convection Oven Model NCG that is being proposed in Subway Sandwich Shops
throughout Minnesota. This document is very similar, but not exactly the same as IARC Document
#03-01 issued April 9, 2003, which addresses the TurboChef Rapid Cook Oven Model No. C3. The
emissions test for total particulate matter was much lower from the test conducted on the previous oven
(0.5mg/m3 vs. 3.8 mg/m3). However, as you will note in the attached conditions for acceptance, unless
there is a sufficient amount of general ventilation existing in the space, additional cooling capacity may
be needed and verified by a certified testing and balancing contractor.
If you have any questions regarding the TurboChef Tornado Oven Model NCG use, you may
contact the Vent Committee Chair, Lorna Girard, at 651/296-1591 or at [email protected]

Re: Turbo-Chef Convection / Microwave Oven Models C3/C and NGC
Dear Mr. Boyd:
You requested an evaluation of the Turbo Chef oven model NGC, that is proposed to be
installed in Subway restaurants state-wide. MDA recommends that both model NGC and C3/C
may be installed and used without ventilation in any food establishment as they are UL197SB
listed. These ovens contain an internal filter and vent that has been shown, under proper test
conditions, to emit very little grease (pepperoni pizzas were used in testing).
Preparation in these ovens without additional ventilation should be limited to pizzas, sub
sandwiches, reheating of par-baked or cooked foods, other similar items and baking. Neither
MDA nor the manufacturer recommends cooking raw, fatty protein products (i.e. raw meat) in
these ovens.
Michigan's mechanical code rules (R 408.30935a) specifically exempt from ventilation "listed
factory-built commercial cooking recirculating systems which are tested in accordance with UL
197" and installed per listing and manufacturer's directions. However, a mechanical inspector
may require ventilation if the building has inadequate general ventilation.
If you have any questions please call me at (517) 373-2779.
Sincerely,
Kevin Besey, Supervisor
