Preventive Maintenance Required by Code

Inspection and Cleaning Requirements
NFPA-96 (Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations)
require that hoods (Ventilators), ducts and exhaust fans must be inspected by a properly trained,
qualified and certified company or person(s) in accordance with the following table.
Systems serving solid fuel cooking operations
Systems serving high-volume cooking operations
such as 24-hour cook, charbroiling or wok cooking
Systems serving moderate-volume cooking
operations
Systems serving low-volume cooking operations
Upon inspection, if found to be contaminated with deposits from grease laden vapors, the entire exhaust
system shall be cleaned by a properly trained, qualified, and certified company or person(s) acceptable
to the authority having jurisdiction.
When a vent cleaning service is used, a certificate showing date of inspection or cleaning shall be
maintained on the premises. After cleaning is completed, the vent cleaning contractor shall place or
display within the kitchen area a label indicating the date cleaned and the name of the servicing
company. It shall also indicate area's not cleaned.
CAUTIONS regarding pressure washing or steam cleaning
Caution 1: The UV Modules must be removed prior to pressure washing or steam cleaning. Very
Important Note: When the UV Modules are removed the opening MUST be blocked to prevent water or
steam from entering the electrical raceways. Blocking Plates are provided when the Ventilator was
shipped from the factory. Blocking Plates may be obtained from Gaylord Industries.
Caution 2: Never use any caustic chemicals as they could damage the aluminum in the ESP Cells. If caustic
chemicals are to be used, the ESP Cells must be removed and cleaned separately.
Caution 3: Some commercial hood cleaning companies blow a fire retardant chemical into hood and duct
systems. Fire retardant chemicals should never be applied to any portion of the Gaylord Ventilator. If
retardant is applied, it must be removed.
