Clearances
☆
Minimum clearance from combustible construction:
6” (15 cm) from the sides of the fryer 6” (15 cm) from the back of the fryer The fryer
may be installed on combustible floors
☆
Minimum clearance from noncombustible construction:
0” from the sides of the fryer 0” from the back of the fryer
☆
Between the fryer and any open-top flame units:
16” (41 cm)
Location
☆Install fryer in an area with sufficient air supply for gas combustion at fryer burners.
☆Do not obstruct the flow of combustion and ventilation air.
☆Provide adequate clearance for air openings into the combustion chamber.
☆Do not permit fans to blow directly onto fryer.
☆Avoid wall-type fans, which create cross-currents within a room. Avoid open windows
next to sides or back.

4
ASSEMBLY
The fryer must be restrained to prevent tipping and the splashing of hot liquid. The means of
restraint may be the manner of installation, such as connection to a battery of appliances,
installing the fryer in an alcove, or by separate means such as adequate ties.
FLUE CONNECTION
Make the flue connection as follows:
☆Locate the fryer under a hood with adequate connection to an exhaust duct.
The hood must extend 6” (15 cm) beyond fryer on both sides.
☆Clearance above the fryer should be adequate for combustion by-products 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 gases from the appliance. Proper air
balance should be maintained in the room.
GAS CONNECTION
All gas supply connections and any pipe joint compound must be resistant to the action of
propane gases.
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.
The gas supply line must be at least the equivalent of ½” (12.7 mm) iron pipe for single units
and 1-1/4” (31.75 mm) for batteries. If using the optional quick-disconnect flex hose, ¾” (19
mm) iron pipe for single units and 1-1/4” (31.75 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 for the gas requirement.

5
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.
GAS PRESSURES (ALL MODELS):
The available gas pressure should be the same as that indicated on naming plate. If incoming
pressure exceeds 5 kPa, an additional pressure regulator must be installed.
TESTING THE GAS SUPPLY PIPING SYSTEM:
When test pressures exceed 5 kPa, the fryer and its individual shutoff valve must be
disconnected from the gas supply piping system.
LEVELING THE FRYER
Check the level of the fryer by placing a level on top of the fryer after gas connections have
been made. Ensure that the fryer is level front-to-back and side-to-side in the final installed
position. If using casters, lock the wheels after unit is level.
Air adjustment

6
Unscrew the locking screw of the burner air shutter and adjust the air shutter to desired height.
In the above picture you can find the suggested height for different types of gases. The height
is the distance between burner base and air shutter.
OPERATION
OVER-TEMPERATURE SHUTDOWN
If the shortening becomes overheated, a high-temperature shutoff device will turn the gas
valve off and extinguish the pilot.
If the fryer shuts down due to overheating, DO NOT re-light the pilot until the shortening
temperature is below 149 ℃(300 ℉)
If an overheating situation persists, contact qualified technician for help.
BEFORE FIRST USE
Cleaning
New units are wiped down at the factory to remove any visible signs of dirt, oil, grease, etc.
remaining from the manufacturing process.

shortening in the cold zone area will remain hard if the heat is only on for 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.
CLEANING
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.
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.
Hot oil and hot parts can cause burns. Use care when operating,
cleaning, and servicing the fryer.
