Cooking equipment manufactured for use in dwelling units and other residential suites is often installed in buildings used for assembly and care or detention purposes. It is not obvious from the Code requirements or those of NFPA 96, “Ventilation Control and Fire Protection of Commercial Cooking Operations,” whether a ventilation and grease removal system is required in all assembly and care or detention uses. If the equipment is to be used in a manner that will produce grease-laden vapours that are substantially more than would be produced in a normal household environment, then it would be appropriate to apply the requirements of NFPA 96. If the equipment is used primarily for reheating food prepared elsewhere or is used occasionally for demonstration or educational purposes, there would be no expectation of applying the requirements of NFPA 96. In all cases the circumstances should be reviewed with the authority having jurisdiction
1)Commercial cooking equipment exhaust and fire protection systems shall be designed and installed in conformance with the NBC.
a) ANSI/UL 300, “Fire Testing of Fire Extinguishing Systems for Protection of Commercial Cooking Equipment,” or
b) ULC/ORD-C1254.6, “Fire Testing of Restaurant Cooking Area Fire Extinguishing System Units.”
Fire Testing of Fire Extinguishing Systems for Protection of Commercial Cooking Equipment
Chapter 12 Minimum Safety Requirements for Cooking Equipment
12.1 Cooking Equipment.
12.1.1 Cooking equipment shall be approved based on one of the following criteria:
(1) Listings by a testing laboratory
(2) Test data acceptable to the authority having jurisdiction
22.214.171.124 All listed appliances shall be installed in accordance with the terms of their listings and the manufacturer’s instructions.
126.96.36.199* Cooking appliances requiring protection shall not be moved, modified, or rearranged without prior re-evaluation of the fire-extinguishing system by the system installer or servicing agent, unless otherwise allowed by the design of the fire-extinguishing system.
188.8.131.52 The fire-extinguishing system shall not require re-evaluation where the cooking appliances are moved for the purposes of maintenance and cleaning, provided the appliances are returned to approved design location prior to cooking operations, and any disconnected fire-extinguishing system nozzles attached to the appliances are reconnected in accordance with the manufacturer’s listed design manual.
184.108.40.206.1 An approved method shall be provided that will ensure that the appliance is returned to an approved design location.
220.127.116.11 All deep-fat fryers shall be installed with at least a 406 mm (16 in.) space between the fryer and surface flames from adjacent cooking equipment.
18.104.22.168 Where a steel or tempered glass baffle plate is installed at a minimum 203 mm (8 in.) in height between the fryer and surface flames of the adjacent appliance, the requirement for a 406 mm (16 in.) space shall not apply.
22.214.171.124.1 If the fryer and the surface flames are at different horizontal planes, the minimum height of 203 mm (8 in.) shall be measured from the higher of the two.
12.2 Operating Controls.
Deep-fat fryers shall be equipped with a separate high-limit control in addition to the adjustable operating control (thermostat) to shut off fuel or energy when the fat temperature reaches 246°C (475°F) at 25.4 mm (1 in.) below the surface.
- (a) Where the food preparation area and the area frequented by the public is interconnected by means
(i) of either normally closed doors or a permanent opening(s) and the total free area of the opening(s) does not exceed 16 ft2 (1.5 m2), the DFMAH shall be interlocked with a mechanical exhaust system and the proven airflow capacity of the interlocked exhaust system shall not be less than 90% of the make-up air supply; or
(ii) other than those indicated in Item (i), the DFMAH shall be interlocked with a mechanical exhaust system and the proven airflow capacity of the interlocked exhaust system shall in no case be less than 100% or more than 105% of the make-up air supply.
