I NSTALLATION
NOTICE
NOTICE
These installation procedures must be followed by qualified personnel or warranty will be void.
Local codes regarding installation vary greatly from one area to another. The National Fire Protection
Association, Inc. states in its NFPA 96 latest edition that local codes are the “authority having
jurisdiction” when it comes to installation requirements for equipment.
Step 1: Unpack
IMMEDIATELY INSPECT FOR SHIPPING DAMAGE
All containers should be examined for damage before and during unloading. The freight carrier has
assumed responsibility for safe transit and delivery. If damaged equipment is received, either apparent
or concealed, a claim must be made with the delivering carrier.
Apparent damage or loss must be noted on the freight bill at the time of delivery. The freight bill must
then be signed by the carrier representative (Driver). If the bill is not signed, the carrier may refuse
the claim. The carrier can supply the necessary forms.
A request for inspection must be made to the carrier within 15 days if there is concealed damage or
loss that is not apparent until after the equipment is uncrated. The carrier should arrange an inspection.
Be certain to hold all contents plus all packing material.

Installation Code, CAN/CGA-B149.2, as applicable.
INSTALLATION
Therma-Tek FRYERS
Step 2: Install the Legs (or Casters) and Restraints
A set of legs or casters is packed with the fryer. Mounting fasteners are pre-mounted on the base plates.
1. Raise fryer sufficiently to allow legs or casters to be screwed into the base plate. For safety, “shore up”
and support the fryer with an adequate blocking arrangement strong enough to support the load.
2. Screw the four legs or casters to the plate on the bottom of the fryer. When casters have been ordered,
the casters having a locking-brake should be attached under the front of the fryer.
4. Use a level to make sure that the fryer is level. Each caster, or the tubular-end of each leg, can be
screwed in or out to lower or raise each corner of the fryer.
5. Attach restraints as required by local codes.
NOTICE
Unit must be level to assure maximum performance. Improper leveling may void warranty.
NOTICE
When this appliance is installed with casters, it must be installed with the casters supplied, a
connector complying with either ANSI Z21.69 CSA 6.16 and a quick-disconnect device complying
with ANSI Z21.41 CSA 6.9. It must also be installed with restraining means to guard against
transmission of strain to the connector, as specified in the appliance manufacturer instructions.
! WARNING
If disconnection of the restraint is necessary to move the appliance for cleaning, etc., reconnect it
when the appliance is moved to its original installed position.
! WARNING
When this appliance is installed with casters, it must be installed with the casters supplied, a connector

Step 4: Check Clearances and Ventilation
Select a firm, level location for your fryer. Leave clearance, whenever possible, so that access from the rear
is possible to permit cleaning. If the unit is to be set on non-combustible flooring, such as a concrete slab, 3
inches minimum toe room must be provided to prevent restriction of the air opening in the bottom of the unit.
! WARNING
Minimum Clearances:
Sides
Rear
From Combustible Construction
6 inches
6 inches
ALL THERMA-TEK FRYERS SHALL BE INSTALLED WITH AT LEAST A 16 INCH SPACE
BETWEEN THE FRYER AND SURFACE FLAMES FROM ADJACENT EQUIPMENT. A FLAME
GUARD IS ACCEPTABLE IF ALLOWED UNDER LOCAL CODE.
No additional side and rear clearance is required for service as the fryer is serviceable from the front.
! WARNING
Improper ventilation can result in personal injury or death. Ventilation that fails to properly remove flue
products can cause headaches, drowsiness, nausea, or could result in death.
Unit Must be installed under a ventilation hood
All units must be installed in such a manner that the flow of combustion and ventilation air is not
obstructed. Provisions for adequate air supply must also be provided. Do NOT obstruct the bottom
front of the unit, as combustion air enters through this area. Be sure to inspect and clean the
ventilation system according to the ventilation equipment manufacturer’s instructions.
Due to the variety of problems that can be caused by outside weather conditions, venting by canopies or wall
fans is preferred over any type of direct venting. It is recommended that a canopy extend 6" past the
appliance and the bottom edge be located 6'6" from the floor. Filters should be installed at an angle of 45° or
more from the horizontal. This position prevents dripping of grease and facilitates collecting the run-off
grease in a drip pan, unusually installed with a filter. A strong exhaust fan tends to create a vacuum in the
room and may interfere with burner performance or may extinguish pilot flames. Fresh air openings
approximately equal to the fan area will relieve such a vacuum. In case of unsatisfactory performance on
any appliance, check the appliance with the exhaust fan in the “OFF” position. Do this only long enough to
check equipment performance, then turn hood back on and let it run to remove any exhaust that may have
accumulated during the test.
The exhaust fan should be installed at least 2 feet above the vent opening at the top of the fryer.
Make sure all ventilation meet local code requirement
This unit is not intended to be connected directly to an outside flue.

Therma-Tek FRYERS
ION
Step 5: Gas Connection
A 3/4" male NPT line for the gas connection is located near the lower right rear corner of the fryer. The serial
plate (located inside the front door of the fryer) indicates the type of gas the unit is equipped to burn (natural
gas or propane). The fryer should be connected ONLY to the type of gas for which it is equipped.
A circuit diagram is located inside the front door of the fryer.
All Therma-Tek equipment is adjusted at the factory; however, pilot height should be checked at installation
and adjusted, if necessary.
If applicable, the vent line from the gas appliance pressure regulator shall be installed to the outdoors in
accordance with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI
Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Installation Code, CAN/CGAB149.2, as applicable.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas
necessary for satisfactory performance. A combination gas valve and pressure regulator, which is provided
with each unit, is set to maintain a 4" W.C. manifold pressure for natural gas or 10.0" W.C. manifold pressure
for propane gas. However, to maintain these conditions the pressure on the supply line, when all units are
operating simultaneously, should not drop below 7" W.C. for natural gas or 11" W.C. for propane gas.
Fluctuations of more than 25% on natural gas or 10% on propane gas will create problems and affect burner
operating characteristics. A 1/8" tap to measure the manifold pressure is located on the combination gas
valve, which is on the burner manifold located directly below the burners inside the cabinet.
Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the unit.
It is recommended that an individual manual shutoff valve be installed in the gas supply line to the unit.
Use pipe joint compound that is suitable for use with both natural and LP gas on all threaded connections.
! CAUTION
ALL PIPE JOINTS AND CONNECTIONS MUST BE TESTED THOROUGHLY FOR GAS LEAKS.
USE ONLY SOAPY WATER FOR TESTING ON ALL GASES. NEVER USE AN OPEN FLAME TO
CHECK FOR GAS LEAKS. ALL CONNECTIONS MUST BE CHECKED FOR LEAKS AFTER THE
UNIT HAS BEEN PUT INTO OPERATION. TEST PRESSURE SHOULD NOT EXCEED 14" W.C.
! CAUTION
THIS APPLIANCE AND ITS INDIVIDUAL COMBINATION GAS VALVE MUST BE DISCONNECTED
FROM THE GAS SUPPLY PIPING SYSTEM DURING ANY PRESSURE TESTING OF THAT
SYSTEM AT TEST PRESSURES IN EXCESS OF 14”WC (1/2 PSIG or 3.45 kPa).
If the incoming gas pressure is in excess of 14"WC (1/2PSI, 3.45 kPa), a proper
step-down regulator will be required. See PHOTO 1 for LP application
Connect the gas supply directly to the 3/4" male NPT connector located near the lower left rear corner of the
fryer. When tightening the supply pipe, be sure to hold the mating connector extending from the unit securely
with a wrench. This will prevent any damage or distortion to the internal piping and controls of the unit.
After connecting the gas supply, check again that the fryer is level. Use a long spirit level four ways; across
the front and rear of the frypot, and along each edge.

For orifice sizes and pressure regulator settings, see the chart on page 4. If the fryer is being installed at over
2,000 feet altitude and that information was not specified when ordered, contact the appropriate authorized
Therma-Tek Service Representative or the Therma-Tek Service Department. Failure to install with proper
orifice sizing will result in poor performance and may void the warranty.

Therma-Tek FRYERS
FILLING THE FRYPOT
1. Close drain valve completely before filling the frypot.
2. When the fryer is new, fill the frypot with water and clean thoroughly (see “Weekly Cleaning” on page 14)
in order to remove protective coatings and any foreign matter.
3. The recommended solid shortening capacity for the frypot (35, 55 or 75lbs) is described on the serial
plate (which is located inside the front door).
4. Remove the basket support frame when filling the frypot with solid shortening.
5. When solid shortening is used, be careful not to bend, break, or twist the thin capillary wires of the
sensing elements located in the frypot.
6. Pack solid shortening into the zone below the tubes, all spaces between the tubes, and at least an inch
above the top of the tubes before lighting the fryer. If any air spaces are left around the heat tube
surfaces when the heat is turned on, the tube surfaces will become red hot, burn the solid shortening,
weaken the frypot, and could result in a fire.
! CAUTION
NEVER ATTEMPT TO MELT A SOLID BLOCK OF SHORTENING ON TOP OF THE HEAT TUBES.
NEVER START THE BURNERS WHEN THE FRYPOT IS EMPTY.
7. To prevent burning or scorching the solid shortening, keep the thermostat set at the lowest temperature
until all the solid shortening between and above the tubes has been melted. Additional solid shortening
can then be added until the desired frying depth has been reached.
SHUTDOWN PROCEDURE
Standby: Turn knob on the combination gas valve to the “PILOT” position. At this setting, only the pilot burner
will remain ignited.
Complete Shutdown: Turn knob on the combination gas valve clockwise, press down on the knob and
continue to turn to the “OFF” position.
RELIGHTING
! WARNING
In the event of a main burner ignition failure, a five minute purge period must be observed prior to reestablishing the ignition source.
1. Shut off all gas.
2. Wait five minutes.
3. Follow the “Lighting” procedure described on page 11.
AUTOMATIC PILOT VALVE
The Automatic Pilot Valve provides an automatic safety shutoff for the fryer when the pilot flame is
extinguished. When the pilot flame is burning, the valve is held open electromagnetically by the electrical
current from a thermopile in the pilot flame. When the pilot flame goes out, generation of current ceases and
the valve closes automatically.

8. Replace the basket support frame over the frypot heat tubes.
SERVICE
Therma-Tek FRYERS
HIGH LIMIT CONTROL
Therma-Tek Fryers are equipped with a secondary heat control that prevents the oil temperature from rising
above 450°F. (Because of the accuracy tolerance of the sensor, the oil temperature may reach as high as
475°F.)
In the event the fryer shuts down due to this condition, the oil must be cooled to below 400°F before the pilot
burner can be re-ignited. When the oil has cooled, use the “Lighting” procedure on page 11 to place the fryer
back in operation. If the problem persists, contact your Therma-tek Service Representative or the ThermaTek Service Department.
COOKING HINTS
USER TIPS
•
Smoking oil means that the temperature is too high, or that the oil has broken down.
•
Gum in frypot denotes a need for thorough cleaning (see “Weekly Cleaning” on page 14)
•
Use different oil for oily foods (mackerel, nutmeg, etc.) than for foods with water-soluble flavors
(potatoes, onions, etc.).
•
Taste cool oil for quality. Replace it regularly.
•
Poor oil cannot produce good food.
C LEANING
Therma-Tek equipment is constructed with the best quality materials and is designed to provide durable
service when properly maintained. To expect the best performance, your equipment must be maintained in
good condition and cleaned daily. Naturally, the frequency and extent of cleaning depends on the amount
and degree of usage.
Following daily and more extensive periodic maintenance procedures will increase the life of your equipment.
Climatic conditions (e.g., salt air) may result in the need for more thorough and more frequent cleaning in
order to keep equipment performing at optimal levels.
! WARNING: BURN HAZARD
If necessary to move the fryer for cleaning, etc., drain oil first to avoid death or serious injury.
! WARNING
If disconnection of the restraint is necessary to move the appliance for cleaning, etc., reconnect it
when the appliance is moved to it originally installed position.
DAILY CLEANING
1. Turn thermostat knob to “OFF” position.
2. Place hot-oil safe container under the drain and drain the frypot completely.
3. Remove the basket support frame (if applicable) and flush out any sediment remaining in the frypot with
a little hot oil.

3. Relight the fryer and bring the solution to a gentle boil for at least five minutes.
4. Turn off main burners and let the solution stand until the gum deposits are softened and the carbon spots
and burned grease spots can be rubbed off.
5. Scrub the frypot walls and heat tubes, then drain out frypot and rinse it with clean water.
6. Refill the frypot with clean water and boil again.
7. Turn off gas and drain and rinse well until clean.
8. Wipe dry with a clean cloth.
9. Refill as specified in the “Filling the Frypot” section (see page 12).
SERVICE
MONTHLY CLEANING
1. Perform the Weekly Cleaning procedure (see previous section).
2. Clean around burner and orifices if lint has accumulated.
3. Visually check that burner carry-over ports are unobstructed.
CLEANING STAINLESS STEEL SURFACES
To remove normal dirt, grease and product residue from stainless steel use ordinary soap and water (with or
without detergent) applied with a sponge or cloth. Dry thoroughly with a clean cloth. Never use vinegar or
any corrosive cleaner.
To remove grease and food splatter or condensed vapors that have baked on the equipment apply cleanser
to a damp cloth or sponge and rub cleanser on the metal in the direction of the polishing lines on the metal.
Rubbing cleanser, as gently as possible, in the direction of the polished lines will not mar the finish of the
stainless steel. NEVER RUB WITH A CIRCULAR MOTION. Soil and burnt deposits that do not respond to
the above procedure can usually be removed by rubbing the surface with SCOTCH-BRITE scouring pads or
STAINLESS scouring pads. DO NOT USE ORDINARY STEEL WOOL, as any particles left on the surface
will rust and further spoil the appearance of the finish. NEVER USE A WIRE BRUSH, STEEL SCOURING
PADS (EXCEPT STAINLESS), SCRAPER, FILE OR OTHER STEEL TOOLS. Surfaces that are marred
collect dirt more rapidly and become more difficult to clean. Marring also increases the possibility of corrosive
attack. Refinishing may then be required.
Darkened areas, called “heat tint,” sometimes appear on stainless steel surfaces where the area has been
subjected to excessive heat. These darkened areas are caused by thickening of the protective surface of the
stainless steel and are not harmful. Heat tint can normally be removed by the above cleaning techniques, but
tint which does not respond to that procedure calls for a vigorous scouring in the direction of the polish lines,
using SCOTCH-BRITE scouring pads or a STAINLESS scouring pad in combination with a powered
cleanser. Heat tint action may be lessened by not applying or by reducing, heat to equipment during slack
periods.

CHECKING AND ADJUSTING PRESSURE REGULATOR
The combination gas valve (includes pressure regulator) is factory set at 4" W.C. for natural gas and 10"
W.C. for propane gas. To check the manifold pressure, do the following:
1. Turn thermostat “OFF” and combination gas valve knob to the “PILOT” setting.
2. Remove pressure tap plug from burner manifold located directly below the burners in the cabinet.
3. Install a fitting appropriate to connect a manometer.
4. Turn combination gas valve to “ON” position and thermostat to “ON.” The burners will ignite. Be certain
that sufficient oil is covering the tubes.
5. With burners on, read manometer.
6. If the manometer does not read 4" W.C. for natural gas, or 10" W.C. for propane gas, adjust regulator.
7. Remove regulator adjustment screw cap (see diagram on page 15).
8. With small screwdriver rotate adjustment screw “CLOCKWISE” to increase or “COUNTERCLOCKWISE”
to decrease pressure. Be sure to adjust with burners “ON.”
9. Turn thermostat “OFF” and set combination gas valve knob to “PILOT” position.
10. Remove manometer and replace pressure tap plug.
11. Replace adjustment screw cap.
All thermostat controls are carefully calibrated at the factory (i.e., the dial is properly set to control appliance
temperatures accurately). Only a qualified appliance service technician should perform this adjustment.
1. To check appliance temperatures, use a thermocouple-type temperature test instrument or reliable
thermometer. Place the thermocouple of test instrument or thermometer in the center of the frypot.
2. Turn the control dial to the temperature setting requiring the greatest accuracy. Allow enough time for
temperature to stabilize, or until several temperature readings are identical.
3. Recalibrate if setting and actual temperature differ by more than 10°F.
4. Remove dial from dial shaft “B.” Be careful that
dial shaft does not rotate in either direction
(which would change the dial setting).
5. Hold dial shaft “B” steady and with a screwdriver
turn calibration screw “A” clockwise to decrease
the temperature, or counterclockwise to increase
the temperature.
6. Replace dial. Let the appliance operate until the
temperature has stabilized before a final check is
