2.3. LEG INSTALLATION
Tilt the fryer to gain access to the bottom of the unit. Using a 7/16" hex wrench, secure the legs to the base
of the fryer with the included 4 hex bolts. (Figure 1) Adjust the legs so that the fryer is level when in position.
NOTE: To avoid the risk of injury, two people are required to handle the unit.

2.4. ATTACHMENT
Do not use the connector or the gas supply hose to restrict fryer movement. Attachment can be done by inserting
the fryer into a battery of appliances or by securing the fryer to the back wall using a chain that is shorter than
the gas supply pipe and a ring. (Figure 2).
NOTE: Attachment material is not included.

2.5. CONNECTION
The 1/2" NPT gas connector is located at the back of the fryer. (Figure 3)
The connection must be made by a licensed technician.
When connecting the gas supply to the unit’s connector, use a second wrench to tighten to prevent
any movement of the internal piping.
WARNING
After connection and before ignition, open the gas supply valve and check the joints for any leaks with soapy water.
Never use a flame to check for gas leaks.
WARNING
Installation must meet the requirements of the codes below, where applicable:
•State codes or local codes, or in the absence of local codes:
•In the United States, national gas code ANSI Z223.1 / NFPA 54;

2.6. GAS PRESSURE CHECK
WARNING
This unit and the gas valve located behind the door must be disconnected from the gas piping supply connected
to the unit during the system pressure test when testing more than ½ psi (3.45 kPa).
1. To measure gas pressure, use the designated opening on the safety valve. (Figure 4)
Normal pressure should be:
•3.5" W.C. for natural gas
•10" W.C. for propane gas
Make sure the burners are operating at maximum capacity while checking the pressure. Operate all other
equipment connected to the gas piping supply at maximum capacity, then read the pressure.
2. Shut off all other appliances and take a second pressure reading. If the pressure varies by more than 1" W.C.,
install a pressure regulator (not included) between the gas piping supply and the unit. (Figure 3)
3. Then adjust the system to the prescribed pressure.

3. OPERATION
WARNING
Accidents associated with transporting the unit when the tank is filled with liquid can cause damage and serious injury.
To prevent an accident when transporting the unit, always empty the fry tank of its liquid as explained in the DRAINAGE
section of this guide.
WARNING
During use, it is very important not to press the ends of the baskets on the chimney of the fryer to prevent oil from
settling on the chimney walls. Oil build-up on the internal or external chimney walls can cause a fire in the fryer.
3.1. FILLING
Before using the fryer, clean the tank with a stainless steel cleaning product designed for fryer maintenance
so as not to contaminate the oil or grease.
1. Close the ball valve located at the front of the fryer. (Figure 5)
2. Fill the tank with 23 liters of oil or melted fat, until the level is one (1) inch from the rear edge of the tank.
(Figure 6)
For use with solid fat, be sure to follow the next steps to melt the fat:
1. Remove the baskets and the screen from the tank.
2. Cut the fat into slices thin enough to fit between the tubes.
3. Fill the tank with slices of fat.
4. Open the thermostat knob for 20 seconds.
5. Close the thermostat knob for 20 seconds.
6. Repeat the previous 2 instructions until the heating tubes are completely covered with melted fat.
WARNING
A melting cycle is necessary when using solid fat to avoid cracking the tank and voiding the warranty,
due to excess heat on the walls of the heating tubes. Excess heat is caused when the surface of the tubes
is not in contact with oil.
