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.

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) for natural gas and 12.0 ± 2.0 inches (3.0 ± 0.5 kPa) 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 a re loo se ned
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), 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), 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 perform ed 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.

(UNDER CAP SCREW)
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.

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 re ceive 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 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
MAIN BURNER
MAIN BURNER ORIFICE
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), 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.
2.3 Thermostat Calibration
Thermostat Calibration Check (Standard)
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.
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 (167 °C) and the burners do not turn off, turn
the thermostat down. Keep lowering the thermostat setting until the burners go out.
e. 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.
