1 Leg Installation and Leveling

This appliance must be installed with legs; it cannot be curb mounted. Curb
mounting will seriously inhibit this appliances ability to effect proper
combustion.

WARNING

This appliance must be installed with the legs provided by the

manufacturer.

WARNING

Do not install legs or perform leveling procedure when unit is in operation or full of cooking medium.

Serious injury could result.

Required tools: 7/16 “ wrench and socket and a large pair of water pump pliers. The legs must be installed
before connecting the appliance to the gas supply. The legs provide the necessary height to meet sanitation
requirements and assure adequate air supply to the combustion system. Use the following procedure.

a. Lay the appliance on its back, being careful not to damage the flue area by pulling on it. Protect

the outside of the appliance with cardboard or a drop cloth when laying it down.

b. Attach each leg with the hex head screws and nuts supplied. Each leg requires four ¼-20 x 5/8”

hex head screws and nuts. Insure that all screws are tight.

c. Mount the screws from the inside of the appliance with the nut on the outside (bottom) of the

appliance. The nuts have lock washers attached to them, therefore it is not necessary to use
lock washers

d. When all four legs are securely mounted, stand the unit up, being careful not to put too much

weight on any one leg. Adjust the height and level the appliance by adjusting the leveling
devices (B) with water pump pliers.

1.1 Installation Clearances

The clearances shown below are for combustible and non-combustible installations and will allow for safe and
proper operation of your appliance.

*For use only on Non Combustible Floors. This appliance must be installed on a fireproof base.

In addition to the above clearances there must also be at least 28 inches (71 cm) of aisle space in front of the
appliance.

1.2 Gas Connection

Your appliance will give you peak performance when the gas supply line is of sufficient size to provide the
correct gas flow. The gas inlet of the appliance is located in the back of the appliance on the lower right hand
side about 21 cm from the floor. The gas line must be installed in accordance with the requirements of AS 5601
or local codes, by a qualified professional. Gas line sizing requirements can be determined by a qualified
installation professional, your local gas company or by the Technical Regulator. The gas line needs to be large
enough to supply the necessary amount of fuel to all appliances without losing pressure to any appliance. A
properly sized and installed gas line will deliver a minimum supply pressure of 7.0 ± 2.0 inches w.c. (1.75 ± 0.5
kPa/17.5± 5 mbar)) for natural gas and 12.0 ± 2.0 inches (3.0 ± 0.5 kPa/30± 5 mbar) for propane to all
appliances connected to the supply line, operating simultaneously at full demand. Each appliance is equipped to
operate on one certain fuel type. The type of fuel with which the appliance is intended to operate is stamped on
the data plate, which is attached to the inside of the door.

1.3 Gas Connection and Sealing Compound

As with any gas appliance, be sure to use a suitable gas joint sealant whenever gas connections are loosened
and retightened. Also remember to check for leaks before allowing the appliance to be put into service.

1.4 Fuel Supply Line Leak and Pressure Testing

The fuel supply system must be tested before the appliance is used. If the fuel line is going to be tested at a
pressure greater than ½ PISG (3.45 kPa/34.5 mbar), insure that that appliance is disconnected from the fuel
line. If the fuel line is to be tested at a pressure equal to or less than ½ PSIG (3.45 kPa/34.5 mbar), the

appliance can be connected during the test, but the unit’s gas valve must be shut. Test all gas line connections

for leaks with a solution of soap and water when pressure is applied.

2 INITIAL ADJUSTMENTS

After the appliance has been properly installed as described in the installation section of this manual, it will need
to be adjusted to ensure that it will perform as designed. These adjustments must be performed by a qualified
person. To perform these adjustments the following tools will be needed:

• Manometer • Digital Thermometer (Temperature Probe)

• DC Millivolt Meter • DC Milliameter

Before you begin filling and adjusting the appliance, perform the following visual checks:

a. After the appliance is in its permanent location, check the levelness. Any additional leveling that

is necessary can be performed as previously described.

b. Check the temperature probe and high limit bulb (in the tank) to ensure that the mounting

screws are tight.

c. Review the installation portion of this manual and ensure

that all steps have been followed and executed properly.

2.1 Pilot Flame Adjustment after gas valve replacement

For manual pilots, refer to the following instructions. Perform this procedure once the pilot is lit.
NOTE: This procedure requires a DC millivolt meter set to a scale of 0-1000 mV.

Using test leads with sharp probes will help in taking the required readings.

a. Locate the thermocouple wires coming from the thermostat/limit box going to the gas

valve. The wire size decreases near the gas valve connections.

b. Using the positive (+) test probe, connect the probe to the high limit wire terminal. On

UFM systems, pierce the high limit wire insulation, with the tip of the test lead probe, at

the gas valve safety magnet connection.
c. Connect the negative (-) test probe to the pilot tubing.
d. Remove the cap screw located below the pilot tubing on the gas

valve. The pilot flame adjustment screw is recessed behind this.

Turning the pilot flame adjustment screw clockwise

lowers the pilot flame and millivolt output. Turning the pilot flame

adjustment screw counter- clockwise increases the pilot flame size

and millivolt output.
e. While monitoring the DC millivolt meter, rotate the pilot flame

adjustment screw in the direction necessary to achieve a reading of

400 ± 50mV.
f. Replace the cap screw.

Note: Allow 3 to 5 minutes between flame adjustments to allow

the reading to stabilize.

MAIN BURNER

MAIN BURNER ORIFICE

2.2 Main Burner System Adjustment

For the main burners to operate the gas supply valve must be open and the thermostat must be turned on. For
models with electric controls, the main power switch must be on. The main burners receive gas from the main
gas supply through the thermostatically controlled valve. When the thermostat is turned up to a setting higher
than the temperature of the oil in the tank, the gas control valve opens.

The main burner pressure must be adjusted to deliver optimum flame. Refer to the following procedure to adjust
the main burners.

CAUTION

Before proceeding any further, fill the tank with WATER. Water is used for the installation

adjustments because the temperature will never exceed 212°F (100°C), thereby allowing plenty of

adjustment time. Never let the water level go below the MIN LEVEL mark stamped on the tank.

a. Ensure that the main gas valve is shut off; remove the manifold pressure tap plug and connect

an accurate pressure gauge having a range from 0 to 16 “ w.c. in 0.1” increments (0 to 4 kPa in

.025 kPa/0-40 in 0.25 mbar increments) or manometer with similar resolution.

b. Turn on this and all appliances connected to the gas supply

line and light their main burners. The pressure reading of

the installed pressure gauge should not drop from the

required installation pressure. Any loss of pressure

indicates inadequate supply line installation, which will

cause poor performance of all appliances during peak

usage.

c. The installed pressure gauge should be the same, ±0.1”

w.c. (.025 kPa/.250 mbar), as that marked on the data plate

on the inside door of the appliance. If the pressure is

correct, go to step e, if it is not, adjust the pressure as

outlined in step d.

d. To adjust the pressure, remove the regulator adjustment

screw cap on the gas valve and, with a flat head

screwdriver, adjust the regulator screw until the proper burner pressure is reached. Turning the

screw clockwise will increase the burner pressure. Turning the screw counterclockwise will

decrease the burner pressure.

e. When the pressure is correct, replace the regulator adjustment screw cover.
f. Turn off the ALL appliances, shut the main gas valve to your appliance and remove the

pressure gauge. Apply pipe joint compound to the manifold pressure tap plug and reinstall it.

3 Thermostat Calibration

NOTICE

Thermostat calibration requires that the temperature of the appliance be raised above 212°F

(100°C). If you have water in the tank you will need to drain it, dry it and fill it with shortening/oil.

Follow the filling instructions in this manual.

3.1 Thermostat Calibration Check (Standard)

To check the calibration of your appliance, refer to the following procedure.

a. Remove the tube screen from the tank.
b. Place the tip of a digital thermometer probe in the shortening/oil approximately one inch above

the temperature sensor.

c. Light the pilot as described in this manual, set the thermostat to 325°F (163 °C) and allow the

shortening/oil to come up to temperature. Watch the thermometer closely as the temperature

rises.

d. If the shortening/oil temperature reaches 350°F (177 °C) and the burners do not turn off, turn

the thermostat down. Keep lowering the thermostat setting until the burners go out.Let the

appliance cycle 4 to 6 times before checking the temperature. Compare the thermometer

temperature against the thermostat setting. If the values are more than 5°F (3 °C) apart,

calibrate the thermostat using procedure in this manual.
