FLUE CONNECTION
Caution: Ensure that your ventilation
system does not cause a down
draft at the fryer's flue opening.
Down drafts will not allow the
fryer to exhaust properly and
will cause overheating which
may cause permanent damage.
Damage caused by down drafts
will not be covered under
equipment warranty.
Caution: Never allow anything to obstruct
the flow of combustibles or
ventilation exiting from the flue.
Caution: Do not put anything on top of
the flue area.
Caution: 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.
Make the flue connection as follows:
GAS CONNECTION
WARNING: NEVER SUPPLY FRYER WITH
A GAS TYPE NOT INDICATED
ON THE DATA PLATE. USING
INCORRECT GAS TYPE WILL
CAUSE IMPROPER
OPERATION. IF YOU NEED TO
CONVERT THE FRYER TO
ANOTHER TYPE OF FUEL,
CONTACT YOUR AUTHORIZED
SERVICE TECHNICIAN.
Caution: All gas supply connections and
any pipe joint compound must
be resistant to the action of
propane gases.
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
of the compound to enter the gas stream,
resulting in clogging of burner orifices
and/or the control valve.
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.
• Comply with Vapor Removal from
Cooking Equipment, ANSI-NFPA Standard
#96 (latest edition), available from the
National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269.
• Locate the fryer under a hood with adequate
connection to an exhaust duct. The hood
must extend 6" (15 cm) beyond fryer sides.
• Clearance above the fryer should be
adequate for combustion byproducts to be
removed efficiently.
• An 18" (46 cm) minimum clearance should
be maintained between the flue vent and the
filters of the hood venting system.
• Never make flue connections directly to
the fryer.
• Do not obstruct the flow of the flue gases
from the appliance. Proper air balance
should be maintained in the room.
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
1-1/4" (3.2 cm) iron pipe for batteries.
Make sure the pipes are clean and free of
obstructions, dirt, and piping compound. A battery
requires one or two connections of appropriate
size and type for the gas requirement.
WARNING: PRIOR TO LIGHTING, CHECK
ALL JOINTS IN THE GAS
SUPPLY LINE FOR LEAKS.
USE SOAP AND WATER
SOLUTION. DO NOT USE
AN OPEN FLAME.
After piping has been checked for leaks, fully
purge gas pipes to remove air.

BASIC FRYING INSTRUCTIONS
• Set the desired temperature and allow
shortening to heat up to that temperature.
• 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.
• Keep shortening between the MIN and MAX
lines. Do not fill the fryer tank past the MAX
line. Shortening will expand when heated.
• Add fresh shortening as needed.
Fry Basket Guidelines
• Do not overfill baskets. (See table for
Recommended Basket Capacities below.)
• Carefully lower basket into oil.
• When frying doughnuts and fritters, turn
product only once during frying.
• When cooking French fries or onion rings,
shake basket several times in a way that
does not splatter the shortening.
EXTENDING SHORTENING LIFE
Shortening life can be extended by following
these guidelines:
• Do not salt foods over the fryer.
• Use good-quality shortening.
• Filter shortening daily (at a minimum).
• Replace shortening if it becomes poorly
flavored.
• Keep equipment and surroundings clean.
• Set thermostats correctly.
• Remove excess moisture and particles
from food products before placing in fryer.
DRAINING THE TANK
WARNING: WHEN HANDLING HOT OIL,
WEAR INSULATED AND OILPROOF GLOVES.
Caution: Before opening the drain valve,
always turn off the fryer. This will
prevent the heating system from
coming on when the tank is empty
and prevent causing a fire.
• 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.
• When frying is completed, remove basket or
product. Hang basket on rear basket hanger.
• Do not salt food over the shortening
because salt could cause a chemical
change in the oil.
Basket Capacities, Recommended
Fryer Model Pounds per
