Ductwork
Grease exhaust ducts must be installed in compliance with NFPA-96, IMC and other applicable codes. Use the
following guidelines when installing the exhaust ducts:
1. Exhaust ducts must be constructed of 16 gauge steel or 18 gauge stainless steel.
2. Exhaust ducts must be constructed with continuous external welds and be grease and water tight.
3. Exhaust duct must be continuously welded to the Ventilator duct collar.
4. All elbows should be sweeping 90's. Right angle turns or elbows less than sweeping may negatively im-
pact the performance of the Ventilator.
5. All horizontal ducts should slope towards the Ventilator and/or towards an approved sump. Amount of
slope must be in accordance with the IMC.
Electrical
Refer to the wiring diagrams on the Gaylord Submittal Drawings for specific wiring interconnections.
1. Provide a 120 volt 20 amp service to the Gaylord Command Center. Optional Voltage 220 volt 50/60 Hz.
2. Wire the Command Center to the designated flex conduit at one end of the Ventilator in accordance with
the electrical diagram.
3. Wire the Command Center to the exhaust and supply fan(s).
4. If the Ventilator is built in multiple sections, and if they contain electric dampers, or thermostats, recon-
nect the flex conduit provided at the section breaks. The electrical contractor is responsible for making
these connections.
5. If the Ventilator is provided with light fixtures, provide a separate 120 volt lighting circuit to one of the
light J-box on the top of the Ventilator. Ventilator may be equipped with built-in light switch.
6. Ventilators built in multiple sections have a flex conduit at the section breaks for interconnecting the light
fixture J-boxes. The electrical contractor is responsible for making these connections.
Additional Electrical for Ventilators with a UV System
Refer to the wiring diagrams on the Gaylord Submittal Drawings for specific wiring interconnections.
1. The UV Lamp Modules are shipped with the Ventilator. They are installed and tested by a Gaylord Certi-
fied Representative at the time of initial Start Up and Demonstration. They must be stored in a clean, dry
environment where they will not be damaged by lift trucks, falling objects, etc.
2. Provide 208–250 VAC, 50/60HZ, Single Phase, 20AMP service to the marked j-box on the top of each
Ventilator section to power the UV Lamp Modules.
3. Ventilators built in no more than two sections have a flex conduit to interconnect the two UV Ballast
Boxes. The electrical contractor is responsible for making this reconnection.
Plumbing (Refer to Figure A-5-1)
Refer to the plumbing diagrams on the Gaylord Submittal Drawings for specific plumbing sizes, and plumbing
interconnections.
1. Provide a hot supply to the Wash Control Cabinet. Note: water temperature requirements 140° F. Min.
to 180° Max., water pressure requirements 40 psi Min. to 80 psi Max.
2. Plumb one 1.00" line from the Wash Control Cabinet to the two connections points on top of each Ven-
tilator section.
3. Run a drain line from the Ventilator drain stub out to a floor sink, or direct connect, as specified. Some
Ventilators built in multiple sections the drains may interconnect. The plumbing is contractor is respon-
sible for making these connections.
4. Run a drain line from the drain stub out on the bottom of the Wash Control Cabinet to a floor sink, or
direct connect, as specified.
