KSCF18G COOL ZONE SERIES GAS FRYERS
CHAPTER 2: IMPORTANT INFORMATION
2.3 Principles of Operation
The incoming gas flows through orifices and is mixed with air in the burners to create the correct
ratio for proper combustion. The mixture is ignited at the front end of each heat tube by the pilot
light. Internal diffusers slow the flame as it goes through the burner tube. This slower and more
turbulent flame gives much better heat transfer to the walls of the tubes, thereby heating the oil more
efficiently.
2.4 Rating Plate
This is attached to the inside of the front door panel. Information provided includes the model and
serial number of the fryer, BTU/hr (kW/hr) input of the burners, outlet gas pressure in inches W.C.
(mbars), and whether the unit has natural (G20/25) or propane (G31) gas orifices.
2.5 Pre-Installation
DANGER
This appliance is equipped with a three-prong (grounding) plug for your protection
against electrical shock and must be plugged directly into a properly grounded
three-prong receptacle. Do not cut, remove, or otherwise bypass the grounding
prong on this plug.
A. General: Only licensed personnel should install any gas-fired equipment.
1. A manual gas shut-off valve must be installed in the gas supply line ahead of the fryers for
safety and ease of future service.
2. The Frymaster KSCF18G gas fryers require 120 volts (AC) 60-cycle electrical service for
non-CE installation (U.S./Canada/Mexico) and 230 volts (AC) 50-cycle electrical service
for CE/International installations. Fryers are equipped with a 16-3 SJT grounded flexible
power cord for a direct connection to the power supply. Amperage draw for each unit
depends on the accessories supplied with the unit. See detailed instructions packaged with
the fryer line-up.
DANGER
No structural material on the fryer should be altered or removed to accommodate
placement of the fryer under a hood. Questions? Call the Frymaster Service Hotline

CHAPTER 2: IMPORTANT INFORMATION
2.6 Air Supply and Ventilation
DANGER
Do not connect this appliance to the gas supply before reviewing each step in this
section.
A. Keep the area around the fryer clear to prevent obstruction of combustion and ventilation airflow
and to allow for service and maintenance. Always adhere to the following:
1. Do not connect this fryer to an exhaust duct.
2. Follow installation and adjustment procedure to ensure adequate airflow to the fryer system.
3. A heavy-duty, commercial fryer’s combustion wastes must vent to the outside of the
building. A deep-fat fryer must be installed under a powered exhaust hood, or an exhaust
fan must be provided in the wall above the unit. Exhaust gas temperatures are
approximately 800-1000°F (427-538°C). Check air movement during installation. Strong
exhaust fans in the exhaust hood or in the overall air conditioning system can produce
slight air drafts in the room and cause erratic burner flames or improper fryer operation.
4. Do not place the fryer’s flue outlet directly into the plenum of the hood, as it will affect the
gas combustion of the fryer.
5. Never use the interior of the fryer cabinet for storage or store items on shelving over or
behind the fryer. Exhaust temperatures can exceed 800°F (427ºC) and may damage or
melt items stored in or near the fryer.
6. Adequate distance must be maintained from the flue outlet of the fryer(s) to the lower edge
of the filter bank. Per NFPA Standards No. 96, a minimum of 18-inches (45-cm) should be
maintained between the flue(s) and the lower edge of the exhaust hood filter.
7. Filters and drip troughs should be part of an industrial hood, but consult local codes before
constructing and installing any hood. The duct system, the exhaust hood, and the filter
bank must be cleaned on a regular basis and kept free of grease.
2.7 Equipment Installed at High Altitudes
A. The fryer input rating [BTU/hr (kW/hr)] is for elevations up to 2,000 feet (610 m). For
elevations above 2,000 feet (610 m), the rating should be reduced 4% for each additional
1,000 feet (305 m) above sea level.
B. The correct orifices are installed at the factory if operating altitude is known at time of the
customer’s order.

Check any installer-supplied intake pipe(s) visually and clean metal particles or other foreign matter
from the threads before installing into a service line. If the intake pipes are not clear of all foreign
matter, the orifices will clog when gas pressure is applied. When using thread compound on gas
piping, use very small amounts and only on male threads. Use a pipe thread compound that is not
affected by the chemical action of LP gases. DO NOT apply thread compound to the first two pipe
threads—doing so will cause clogging of the burner orifices and control valve.
Manual Shut-off Valve
This gas service supplier-installed valve must be installed in the gas service line ahead of the fryers
in the gas stream and in a position where it can be reached quickly in the event of an emergency.
Regulating Gas Pressure
The fryer and its individual shut-off valve must be disconnected from the gas supply piping system
during any pressure testing of the gas supply system, especially if the test pressures are in excess of
½ PSI (3,45 kPa/35 mbar).
External gas regulators are not normally required on this fryer. A safety control valve protects the
fryer against pressure fluctuations. If the incoming pressure is in excess of ½ PSI (3,45 kPa/35
mbar), a step-down regulator is required.
DANGER
When pressure-testing incoming gas supply lines, disconnect the fryer from the gas
line if the test pressure is 3,45 kPa (½ PSI, 14" W.C.) or greater to avoid damage to
the fryer’s gas piping and gas valve(s).
A. Manifold Pressure: Your local service technician should check the manifold pressure with
a manometer.
1. Check the rating plate for manifold gas pressures. Natural gas units normally require 4"
W.C., and propane units normally require 11" W.C. gas pressure.
2. Confirm that the arrow forged into the bottom of the regulator body, which indicates gas
flow direction, is pointed downstream towards the fryers. The air vent cap is also part of the
regulator and should not be removed.
3. If a vent line from the gas pressure regulator is used, it should be installed in accordance
with local codes or in the absence of local codes, with the National Fuel Gas Code, ANSI
Z223.1-(Latest Edition).

WARNING
Use a diluted soap solution to find potentially dangerous gas leaks when making
new connections.
B. Regulators: Gas regulators can be adjusted in the field, but no adjustments should be made
unless the regulator is out of adjustment or serious pressure fluctuations are observed.
C. Only qualified service personnel should make adjustments to the regulators.
D. Orifices: The fryer can be ordered to operate on any available gas. The correct
combination gas valve, appropriate burner orifices, and pilot burners are installed at the
factory. While the valve can be adjusted in the field, only qualified service personnel should
make any adjustments with the proper test equipment.
DANGER
If gas odors are detected, the gas supply must be shut off at the main shut-off valve.
The local gas company or FASC should be contacted immediately to fix the problem.
E. Flexible Couplings, Connectors and Casters:
1. If the fryer is to be installed with flexible couplings and/or quick-disconnect fittings, the
installer must use a heavy-duty AGA design-certified commercial flexible connector of
at least ¾" NPT (with suitable strain-relief attachments), in compliance with the
Standard for Connectors for Movable Gas Appliances, ANSI Z21.69-(Latest Edition)
and Addenda Z21.69a-(Latest Edition). Quick disconnect devices must comply with the
Standard for Quick-Disconnect Devices for Use with Gas Fuel, ANSI Z21.41-(Latest
Edition).
2. For an appliance equipped with casters, the installation shall be made with a connector
that complies with the Standard for Connectors for Movable Gas Appliances, ANSI
Z21.69, or Connectors for Moveable Gas Appliances, CAN/CGA-6.16. A quickdisconnect device that complies with the Standard for Quick-Disconnect Devices for Use
with Gas Fuel, ANSI Z21.41, or Quick-Disconnect Devices for Use with Gas Fuel,
CANI-6.9, must be used. Under no circumstances are the connector and the quickdisconnect device or its associated piping to be used to limit fryer movement.
3. The fryer must be restrained by means independent of the flexible coupling or connector
in order to limit the movement of the fryer. Clips are located on the back panel of the
fryer for the attachment of restraints.

3.9 Safety Switches
A. Fryer with KFC-1 Computer
This fryer/filter system is equipped with a drain valve safety switch and a frypot float-switch on
each of the two-batteried fryers. Drain-valve safety switches de-energize the control circuit
during the filter process, thus providing an additional safety feature. Always leave the computer
ON when filtering.
The KFC-1 computer monitors cooking operations. The computer logs the number of cook
sequences and locks out the cook cycle after a preset number is reached. The drain-valve must
be opened, the oil must be filtered, and the drain-valve closed before the KFC-1 computer will
allow a cook cycle. After filtering, always allow the frypot to refill with oil and heat to setpoint
before engaging a cook cycle.
See the accompanying KFC-1 SMS Cooking Computer User Manual for more detailed
information.

CHAPTER 3: INSTALLATION INSTRUCTIONS
3.10 Initial Cleaning Before Startup
New units are wiped clean with solvents at the factory to remove any visible signs of dirt, oil, and
grease remaining from the manufacturing process. Then, they are coated lightly with oil. Wash
thoroughly with hot, soapy water to remove any film residue and dust or debris before food
preparation. Then, rinse and wipe dry. In addition, wash any accessories shipped with the unit. Close
the drain valve completely and remove the crumb screen. Ensure the screws securing the
temperature probe to the bracket between heating tubes are tight.
WARNING
All droplets of water must be removed from the frypot before filling with shortening.
Failure to do so will cause hot oil to splatter and injure the operator.
3.12 Final Preparation
1. The KSCF18G frypot shortening capacity is approximately 40.5 kg (90 lb).
2. Ensure fryer power switches are OFF.
3. Cooking Oil: Fill the fryer to the bottom OIL LEVEL line scribed into the back of the
frypot. Replace the basket support screen.
WARNING
Never operate fryer without enough oil, shortening, or water in the frypot to cover
the heating tubes.
WARNING
NEVER set a complete block of solid shortening on top of heating tubes. To do so
will damage the frypot and increase the potential for flash-point shortening
temperatures and subsequent fire.
4. Solid Shortening: Either pre-melt solid shortening on another appliance first or cut it into
small pieces and pack it tightly into the cool zone at the bottom of the frypot. Take care not
to disturb the temperature probe or high-limit thermostat. If solid shortening is packed into
the frypot, ensure the float switch is in the "up" position.
