GAYLORD CG Series, Technical Manual

Page: 19 / 48

Each Gaylord Ventilator is engineered to properly ventilate the
specific cooking operation. The exhaust air volume is engi-
neered as a specific volume per lineal ft. of ventilator and is
determined by the type of cooking equipment being ventilated.
The following Air Volume Chart lists the various volumes per
lineal ft. designs.
A ventilator may be designed to operate at two different air
volumes. For example, half the ventilator may operate at 150
CFM/Lin. Ft. by utilizing “Custom Air” Baffles, and the other
half at 250 CFM/Lin. Ft.
Refer to “Measuring Inlet Slot Velocity” on Page 22 for
instructions on how to determine the designed Air Volume/Lin.
Ft.
The total exhaust volume for each ventilator is stamped on the
ventilator nameplate. (Refer to Figure 26 on Page 24.)

WATER TEMPERATURE REQUIREMENTS
WATER PRESSURE REQUIREMENTS
WATER CONSUMPTION
The length of the wash cycle may be set for 3 different times,
3 minutes for light-duty equipment, 5 minutes for medium-duty
equipment, and 9 minutes for heavy-duty equipment.
ELECTRICAL REQUIREMENTS
Standard voltage 120 volt, 60 Hz. Provide 24 hour, 20 amp
service.
Optional voltage 220 volt, 50 Hz. 220 volt. All controls are
marked with their operating voltage. See pages 34 through 41.
MAKE-UP AIR
Make-up air must be supplied for replacement of air exhausted
through all kitchen exhaust systems. Make-up air should be
delivered through registers at ceiling height and distributed
throughout the kitchen. A general "rule of thumb" is that 75%
to 80% of the replacement air should be fresh, conditioned
(heated or cooled) air brought into the kitchen area -- with the
remaining 20% to 25% allowed to flow into the kitchen from
adjacent areas.
NOTE: RECOMMENDED PERCENT OF MAKE-UP AIR FOR
"MA" SERIES VENTILATORS INCORPORATING INTEGRAL
MAKE-UP AIR WILL VARY. REFER TO THE GAYLORD
MASTER ENGINEERING DATA SHEET FOR SPECIFIC
REQUIREMENTS.
NOTE: AIR VOLUME AND STATIC PRESSURE REQUIRE-
MENTS ARE BASED UPON OPERATION AT MEAN SEA
LEVEL UNLESS OTHERWISE INDICATED. AIR VOLUME
AND STATIC PRESSURE MUST BE CORRECTED FOR
HIGH ALTITUDES.
