Installation Requirements - cont.
Air Flow Rates
The exhaust air flow rate (and supply if part of the Ventilator) must be set at the rate stamped on the Ventila -
tor nameplate. The exhaust volumes (and supply when provided) were established under controlled labora-
tory conditions and greater exhaust and/or lesser supply may be required for complete grease, smoke and
vapor removal in specific situations.
Fire Extinguishing System
NFPA-96 requires a Fire Extinguishing System in all Ventilators that cover cooking equipment producing
grease laden vapors. In many cases the Fire Extinguishing System is pre-piped by Gaylord Industries in the
factory with completion of the system by a local Fire System contractor. If not pre-piped then the entire sys -
tem would be installed by a local Fire System contractor. Use the following guidelines:
1. Fire Extinguishing System furnished must be in accordance with the terms of its listing and the applicable
NFPA or IFC codes and standards.
2. Caution: Fire extinguishing system piping installed on the Ventilator at jobsite should be coordinated with
Gaylord Industries to ensure piping does not interfere with the Ventilator’s operation and performance.
Improper installation may void Listings of the Ventilator.
3. IMPORTANT NOTE: NFPA-96 requires that all gas cooking equipment, and electric cooking equipment
that is protected by a Surface Fire Extinguishing System must automatically shut off upon activation of
the system.
4. Most building departments require a separate Fire Extinguishing System permit from any other general
building or Ventilator permit. Installing contractor to check with local building departments for their
requirements, and to obtain necessary permits.
