Checking the Gas Supply Pressure
Record your fryer model, device, and serial
numbers for future reference in the space
provided below. This information can be found
on the fryer data plate.
Caution:
The fuel supply system must be
tested before the fryer is used.
If the fuel line is going to be tested at a pressure
greater than 1/2 psig (3.45 kPa), make sure that
the fryer is disconnected from the fuel line. If the
fuel line is to be tested at a pressure equal to or
less than 1/2 psig (3.45 kPa), the fryer can be

Down drafts will not allow the
fryer to exhaust properly and
will cause overheating which
may cause permanent damage.

SERVICE TECHNICIAN.
Damage caused by down drafts
will not be covered under

Caution:
All gas supply connections and
any pipe joint compound must
be resistant to the action of
propane gases.
Caution:
Never allow anything to obstruct
the flow of combustibles or
ventilation exiting from the flue.
Note: When using thread compound, use very
small amounts on male threads only.
DO NOT apply compound to the first
two threads. Doing so may allow some

resulting in clogging of burner orifices
and/or the control valve.
Caution:
Caution:
Do not put anything on top of
the flue area.
Never connect blower directly
to flue openings. The direct flow
of air will cause poor ignition,
poor temperature recovery,
inefficient operation of the fryer,
and could extinguish the pilot.
The gas inlet is located on the lower rear of the
fryer. Codes require that a gas shutoff valve be
installed in the gas line ahead of the fryer.
Make the flue connection as follows:
The gas supply line must be at least the
equivalent of 1/2" (1.3 cm) iron pipe for single
units and 1-1/4" (3.2 cm) for batteries. If using
the optional quick-disconnect flex hose,
3/4" (1.9 cm) iron pipe for single units and

GR SERIES GAS FRYERS
BASIC FRYING INSTRUCTIONS
EXTENDING SHORTENING LIFE
•
•
•
Set the desired temperature and allow
shortening to heat up to that temperature.
Shortening life can be extended by following
these guidelines:
•
•
•
•
Do not salt foods over the fryer.
Use good-quality shortening.
Fry items that are about the same size
together to ensure equal doneness.
Drain or wipe dry raw or wet foods to
minimize splatter when lowering into the
hot shortening.
Filter shortening daily (at a minimum).
Replace shortening if it becomes poorly
flavored.
•
•
Keep shortening between the MIN and MAX
lines. Do not fill the fryer tank past the MAX
line. Shortening will expand when heated.
•
•
•
Keep equipment and surroundings clean.
Set thermostats correctly.
Remove excess moisture and particles
from food products before placing in fryer.
Add fresh shortening as needed.
Fry Basket Guidelines
DRAINING THE TANK
•
Do not overfill baskets. (See table for
WARNING: WHEN HANDLING HOT OIL,
WEAR INSULATED AND OIL-
PROOF GLOVES.
Recommended Basket Capacities below.)
•
•
Carefully lower basket into oil.
When frying doughnuts and fritters, turn
product only once during frying.
Caution:
Before opening the drain valve,
always turn off the fryer. This will
prevent the heating system from
comingonwhenthetankisempty
and prevent causing a fire.
•
•
When cooking French fries or onion rings,
shake basket several times in a way that
does not splatter the shortening.
Batter-covered foods should be dropped
carefully, one by one, into shortening or
basket. If you use the basket, first dip
basket into shortening to reduce batter
build-up on basket surfaces.
You will need a container capable of holding
400°F (204°C) oil and insulated oil-proof
protective gloves.
1. Heat shortening to a liquid state.
2. Turn the thermostat to OFF.
•
•
When frying is completed, remove basket or
product. Hang basket on rear basket hanger.
3. To keep the pilot lit, turn the gas valve knob to
“I”inPILOT(free-standingmodels),orthegas
valve handle to “PILOT” (KleenScreen™
models).
Do not salt food over the shortening
because salt could cause a chemical
change in the oil.
4. Direct the drain down spout into the container
that you want to drain the shortening into.
Basket Capacities, Recommended
5. Open the drain valve. The oil will drain into
the container. When the container is full or
the fryer tank is empty, close the drain valve.
Repeat this step until fryer tank is empty.

•
Filter shortening at least once a day.
Refer to the instructions provided with
your filtering equipment.
Daily
Clean your fryer regularly with the tank brush
along with a damp cloth, and polish with a soft
dry cloth. If regular cleaning is neglected, grease
will be burned on and discolorations may form.
•
A cold fryer will not drain properly. Always
filter shortening between 250°F and
350°F. The shortening under the heat
pipes in the cold zone area will remain
hard if the heat is on for only a few
minutes. If necessary, use the clean-out
rod to carefully stir the hard shortening to
an area above the cold zone where it will
melt. Use the tank brush to help clear
sides and tubes of debris.
Fingerprints are sometimes a problem on highly
polished surfaces of stainless steel. They can
be minimized by applying a cleaner that will
leave a thin oily or waxy film.
•
Clean all exterior surfaces of your fryer at
least once daily.
•
Use a damp cloth with warm water and a
mild soap or detergent.
Note: Do not use chlorine or sulfate/sulfide
cleaners.
•
•
Rinse thoroughly, then polish with a soft,
dry cloth.
Keep the fryer exterior clean and free of
accumulated grease to prevent stubborn
stains from forming. If regular cleaning is
neglected, grease will become burned on
and discolorations may form.
