models are listed in this manual.

2-1

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

as well as for service and maintenance and adhere to the following:

1. Do not connect this fryer to an exhaust duct.

2. Correct installation and adjustment will ensure adequate airflow to the fryer system.

3. A commercial, heavy-duty fryer’s combustion wastes must be vented 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, as 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, which can cause erratic burner flames and/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 any 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.

B. After the fryer has been positioned under the exhaust hood, ensure the following has been

accomplished:

1. Adequate means must be provided to limit the movement of fryers without depending upon
gas connections. If a flexible gas hose is used, a restraining cable must be connected at all
times when the fryer is in use. The restraining cable and installation instructions are
packed with the flexible hose in the accessories box that was shipped with your unit.

2-4

CHAPTER 2: IMPORTANT INFORMATION

2.6 Air Supply and Ventilation (cont.)

2. Single unit fryers must be stabilized by installing restraining chains on appliances
equipped with casters or anchor straps on appliances equipped with legs. Follow
instructions shipped with the casters/legs to properly install the chains or straps.

DANGER

Do not attach an apron drain board to a single unit. The appliance may become

unstable, tip over, and cause injury. The appliance area must be free and clear of

combustible material at all times.

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 four percent 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.

2.8 Conversion of Units

Pressure:

1 mbar = 10.2 mm water column (mm W.C.) = 0.4 Inch WC
20 mbar = 204 mm W.C. = 8 Inch W.C.

4. Insert hex head screws with lock washers [1/4-20 threads by ¾" (19-mm) long] through bolt
holes of leg mounting plates and mount to the front channel. Mount rigid casters to the rear
channel following the same procedure. Locknuts have been attached to the topside of the
base mounting plates at the factory to capture hex head screws as they are screwed in.

5. Tighten the bolts to 50 inch-lbs. (5.65 joules) minimum torque.

WARNING

For caster retrofit, the unit must be at room temperature and drained of shortening

before installing the casters.

3.3 Leveling the Fryer

A. Place a carpenter’s spirit level across the top of the fryer and level the unit front-to-back. If the

fryer is off level side to side, a platform or other surface adjustment is needed; there is no side to
side level adjustments on a fryer equipped with caster/leg combinations (If a fryer is equipped
with legs only, side to side level adjustments can be made. If a fryer is equipped with casters
only, no level adjustments to the fryer can be made.). If the fryer is not level, the unit may not
function efficiently, the oil may not drain properly for filtering and in a multi-fryer battery, it
may not match adjacent units.

Legs (Only)

1. Adjust leg height with an adjustable or 1-1/16-inch (27-mm) open-end wrench by turning
the hex bullet on the bottom of the leg.

3.3 Leveling the Fryer (cont.)

ANSI Z83.11a-(Latest Edition) requires a fryer be restrained to prevent tipping when installed
in order to avoid the splashing of hot liquid. The means of restraint may be the manner of
installation, such as connection to battery of appliances or installing the fryer in an alcove, or
by separate means, such as adequate ties (chains, straps, etc.). A bracket has been provided on

the fryer back panel for this purpose.

NOTE: The installation must be inspected after it is complete to ensure it meets the intent of
these instructions. The on-site supervisor and/or operator(s) should be informed that the
appliance is installed with restraints. If restraints are removed to move fryer (cleaning
beneath and behind, relocation, etc.), ensure that they are re-installed when fryer is returned
to its permanently installed position.

CHAPTER 3: INSTALLATION INSTRUCTIONS

3.4 Gas Connections (cont.)

Supply Line Specifications

The gas supply lines must be sized as indicated in the chart below, based on the total number of
fryers connected to the main gas supply.

Gas Types Number of Fryers

1 2 to 3 4 or more (*)
Natural Gas 3/4" (22 mm) 1" (28 mm) 1 1/4" (35 mm)
Propane Gas 1/2" (15 mm) 3/4" (22 mm) 1" (28 mm)
(*) When exceeding 18 feet (6 meters) for a configuration of more than four fryers, it is necessary

to provide a 1 1/4" (35 mm) rigid gas connection.

Recommended Gas Supply Line Sizes

DANGER

All connections must be sealed with a joint compound suitable for the gas being

used and all connections must be tested with a solution of soapy water before

lighting any pilots.

Never use matches, candles, or any other ignition source to check for leaks. If gas

odors are detected, shut off the gas supply to the appliance at the main shut-off

valve and immediately contact the local gas company or an authorized service

agency for service.

DANGER
"Dry-firing" your unit will cause damage to the frypot and can cause a fire. Always
ensure that melted shortening, cooking oil or water is in the frypot before firing the

unit.

DANGER

Before connecting new pipe to this appliance, the pipe must be blown out

thoroughly to remove all foreign material. Foreign material in the burner and gas

controls will cause improper and dangerous operation.

KSCF18G COOL ZONE SERIES GAS FRYERS
CHAPTER 3: INSTALLATION INSTRUCTIONS

3.4 Gas Connections (cont.)

Rigid Connections

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 shut-off valve must be disconnected from the gas supply during any pressure testing of
the system.

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 will be 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).

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).

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"
WC, and propane units normally require 11" WC 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.

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 rectify 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 3/4" 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 be used to limit fryer movement. A restraining
