1.4 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 line must be installed to meet the local building codes or National Fuel
Gas Code ANS Z223.1 and NFPA 54 (latest editions). In Canada, install the appliance in accordance
with CSA B149.1 or .2 and local codes. Gas line sizing requirements can be determined by a qualified
installation professional, your local gas company or by referring to the National Gas Fuel Code,
Appendix C, Table C-4 (for natural gas) and Table C-16 (for propane). 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 supply pressure between 7.0” W.C.
(17.4mbars, 1.74kPa) and 10.0”W.C. (24.9mbars, 2.49kPa) natural gas or between 11.0”W.C.
(27.4mbars, 2.74kPa) and 13.0” W.C. (32.4mbars, 3.25kPa) propane to all appliances connected to
the supply line, operating simultaneously at full demand. The pressure at the gas valve shall not
exceed ½ PSI.

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.

WARNING
NEVER supply the appliance with a gas other than the one that is indicated on the data
plate. Using the incorrect gas type will cause improper operation and could result in serious
injury or death. If you need to convert the appliance to another type of fuel, contact the
dealer

ou purchased it from.

NOTICE
NEVER use an adapter to make a smaller gas supply line fit the appliance connection. This
may not allow proper gas flow for optimum burner operation, resulting in poor performance
and improper operation.

1.5 QUICK DISCONNECT CONNECTION

Gas appliances equipped with casters must be installed with connectors that comply with the
Standard for Movable Gas Appliances, ANSI Z21.69 • CSA 6.16 latest edition. This connection should
include a quick disconnect device that complies with the Standard for Quick Disconnect Devices for
Use With Gas Fuel, ANSI Z21.41 • CSA 6.9 latest edition. When installing a quick disconnect you
must also install adequate means for limiting the movement of the appliance without depending on
the connector and quick-disconnect device or it’s associated piping to limit the movement of the
appliance. The restraining device should be attached to the appliance on the back panel.

1.6 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.

1.7 HEAT DEFLECTOR

1.11 VENTILATION AND FIRE SAFETY SYSTEMS

Your new appliance must have proper ventilation to function safely and properly. Exhaust gas
temperatures can reach as high as 1100 °F (593 °C). Therefore, it is very important to install a fire
safety system. Your ventilation system should be designed to allow for easy cleaning. Frequent
cleaning and proper maintenance of the ventilation system and the appliance will reduce the chances
of fire. Ventilation and fire safety systems must comply to local and national codes. Refer to ANSI
Z83.11• CSA 1.8 for a list of reference documents that will provide guidance on ventilation and fire
safety systems. For installations in U.S. and Canada, additional information can be obtained from
CSA International, 8501 East Pleasant Valley Road, Cleveland, OH, 44131 or visit their website at
www.csa-international.org.

It is essential that the appliance be operated only when adequate ventilation is provided. Your
ventilation hood should be properly maintained. A qualified installation professional should ensure that
the hood is operating properly in conjunction with the appliance. Inadequate ventilation may not
properly evacuate appliance all emissions. Excessive or unbalanced ventilation may cause drafts,
which could interfere with proper operation of the pilot and burners. Leave at least 18 inches
(45.72cm) of open space between the flue of the appliance and the intake of the exhaust hood.

WARNING
Ensure that your ventilation system does not cause a down draft at the appliance’s flue
opening. A down draft will not allow the appliance to exhaust properly and will cause
overheating, which may cause permanent damage. Damage caused by down drafts will not
be covered by the warranty. NEVER allow anything to obstruct the flow of combustibles or
ventilation exiting the appliance. NEVER place anything on top of the flue area, or block the
flue in any way. Never place a grease condensating drip pan over the flue opening.

WARNING
NEVER connect the ventilation blower or hood directly to the flue of this appliance. The
resulting increased flow of air through the combustion system will cause improper
operation, poor temperature recovery, poor ignition and could extinguish the pilot.

1.13.4 MAIN BURNER SYSTEM ADJUSTMENT

For the main burners to operate the gas supply valve must be open and the thermostat must be
turned on. The main power switch must be on. The main burners receive gas from the main gas
supply through the thermostatically controlled valve. When the water temperature drops below
the preset temperature the gas control valve opens.

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

1. Ensure that the main gas valve is shut off, remove the manifold pressure tap plug and
connect an accurate pressure gauge (range of 0-16 “W.C. (39.85 mbar, 3.98 kPa) in 0.1”
(.25 mbar, .02 kPa) increments) or manometer.

2. 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 below the minimum indicates inadequate supply
line installation, which will cause poor performance of all appliances during peak usage.

3. The burner pressure should be the same, ±0.1” W.C. (.25 mbar, .02 kPa), as that marked on
the data plate on the inside door of the appliance. If the pressure is correct, go to step 6, if it
is not, adjust the pressure as outlined in step 4.

4. To adjust the pressure, remove the regulator adjustment screw cap 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.

5. When the pressure is correct, replace the regulator adjustment screw cover.

6. Turn off the ALL appliances, shut the main gas valve to your Pitco appliance and remove the
pressure gauge. Apply pipe joint compound to the manifold pressure tap plug and reinstall it.

2. Cut the solid shortening into
cubes no larger than one
inch. ALWAYS pack the
shortening below, between,
and on top of the burner
tubes. Do NOT leave any
large air gaps. Use care
when packing the solid shortening into the tank. Do NOT bend or break the
temperature or high limit sensor probes. If these are damaged the appliance will not
function properly.

3. Once the appliance tank is firmly packed with shortening, the shortening must be
melted. Melt the shortening by using the solid melt cycle in the fryer’s computer control.
In solid melt cycle mode the computer will cycle the heat on and off to slowly melt the
shortening.
