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

Food Service Sanitation Section

Food and Dairy Division
