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

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

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: 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.

RE: Exemption from mechanical exhaust ventilation for TurboChef Technologies,Inc.
Model Tornado (NGC) and Tornado 2 (NGCD6) ovens
Dear Mr. Pool:
The County of Los Angeles Department of Public Health, Environmental Health, Plan Check has
completed a review of the TurboChef Technologies, Inc. Model: Tornado (NGC) and Tornado 2
(NGCD6) ovens for exemption from the mechanical exhaust ventilation requirements of Section
114149.1(a) of the California Retail Food Code.

You have provided documentation that these ovens have Underwriter's Laboratory KNLZ
approval, and also provided the results of the eight-hour cooking emissions test conducted on the
Tornado (NGC) oven. The test results indicate that the particulate matter concentration produced
was 1.153 ffidfrì', which is below the limit of 5 mg/ m'to be considered a low grease emission
appliance.

This exemption shall be in effect for a period of five years from the date of this letter, or until
revoked. However, this exemption shall not preclude this Department from requiring the
installation of mechanical exhaust ventilation when operation of the Tomado or Tornado 2 oven
at a specific location results in a sanitation or safety violätion. 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 Tomado (NGC) or
Tornado 2 (NGCD6) rapid cooking ovens. However, it is not to be construed as an endorsement
of the subject items and may not be used for advertising or promotional purposes.
