Checking Your New Appliance  
Your new appliance has been carefully packed into one crate. Every effort has been made to ensure that you it  
is delivered to you in perfect condition. As you unpack your new appliance, inspect each of the pieces for  
damage. If something is damaged, DO NOT sign the bill of lading. Contact the shipper immediately; the shipper  
is only responsible for 15 days after delivery. Check the packing list enclosed with your appliance to ensure that  
you have received all the parts to the appliance. If you are missing any parts, contact the dealer from whom the  
appliance was purchased. As you unpack the appliance and its accessories be careful to keep the weight of the  
appliance evenly distributed.  
CAUTION  
To prevent equipment damage and/or personal injury, do not tilt the appliance onto any  
two of its casters or legs, or pull the appliance by the flue vent.  
Locate your warranty and fill in the serial number of the appliance and the date of purchase and write them on  
the cover of this manual for future reference. You will find the serial number on the date plate located inside the  
door or on the back lower panel  
Assembly and Leveling  
When you receive your appliance it is completely assembled with the possible exception of the legs (or casters)  
and heat deflector.  
Leg/Caster Installation and Leveling  
This appliance must be installed with legs or casters; 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 or casters provided by the manufacturer.  
WARNING  
Do not install legs or casters, 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/casters 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.  
b.  
c.  
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.  
Attach each leg/caster with the hex head screws and nuts supplied. Each leg/caster requires  
four ¼-20 x 5/8” hex head screws and nuts. Insure that all screws are tight.  
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/casters 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. On casters, loosen 2 screws (A) before leveling, then  
retighten.

INSTALLATION/OPERATION  
Heat Deflector Installation  
If the appliance requires a heat deflector, you will find a removable label at the rear top edge of the unit. This  
label has instructions for positioning and installation of the heat deflector. Refer to the label and the instructions  
below to install the deflector.  
a.  
b.  
Remove the two self-drilling screws from the top, back area of the appliance.  
Position the heat deflector so that the angled portion of the deflector is facing toward the front of  
appliance. Secure the heat deflector to the back of the unit using the two previously removed  
fasteners.  
c.  
When properly installed the angled section of the heat deflector will extend over the flue  
opening to redirect the heat. It SHOULD NOT cover the flue opening. Never allow anything to  
block the flue opening; this will cause the appliance to over heat and inhibit proper combustion,  
which could produce dangerous gases  
Installation  
If you have completed the above steps that are applicable to the appliance you purchased, the appliance is now  
ready to be installed. Although it may be possible for you to install and set up your new appliance, it is  
STRONGLY recommended that you have this done by qualified professionals. A qualified professional will  
ensure that the installation is safe and meets local building and fire codes.  
WARNING  
DO NOT obstruct the flow of combustion, ventilation or air openings around the appliance.  
Adequate clearance around the appliance is necessary for servicing and proper burner  
operation. Ensure that you meet the minimum clearance requirements specified in this  
manual.

In addition to the above clearances there must also be at least 28 in (71.2cm) of aisle space in front of the unit.  
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 minimum supply pressure of 7.0 ± 2.0  
inches w.c. (17.4 ± 5 mbar) for natural gas and 12.0 ± 2.0 inches w.c. (29.9 ± 5 mbar) for propane gas  
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.

INSTALLATION/OPERATION  
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 you purchased it from.  
NOTICE  
NEVER use an adaptor 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.  
Quick Disconnect Gas 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 its associated piping to limit the movement of the appliance.  
The restraining device should be attached to the appliance on the back panel.  
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.  
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. The following tables contain a list of reference documents that will provide guidance on  
ventilation and fire safety systems. It is not necessarily complete. Additional information can be  
obtained from CSA International, 8501 East Pleasant Valley Road, Cleveland, OH, 44131 or visit their

INSTALLATION/OPERATION  
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 (46 cm) of open space between the flue of the appliance and the  
intake of the exhaust hood.  
CAUTION  
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.  
NOTICE  
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.  
Initial Adjustments  
After your 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  
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.  
c.  
Check the temperature probe and high limit bulb  
(in the tank) to ensure that the mounting screws  
are tight.  
Review the installation portion of this manual and  
ensure that all steps have been followed and  
executed properly.  
Ensure that these  
Parts are not loose  
Burner Ignition Systems  
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 “OIL LEVEL” mark  
stamped on the tank.

in and hold a flame to the pilot until the pilot ignites; this may take a little while  
the first time you light the pilot because of the air in the lines. Once lit, hold  
the knob in for approximately one minute and then release.  
d.  
If the pilot goes out, wait 5 minutes and repeat step C. If after three tries the  
pilot will not remain lit, refer to the operator troubleshooting section of this  
manual.  
e.  
f.  
Once a pilot flame has been established, turn the gas valve knob  
counterclockwise to the ON position.  
Set the thermostat control knob to the desired temperature setting, The main  
burners will ignite and be controlled by the thermostat.  
Pilot Flame Adjustment  
For manual pilots, refer to the following instructions. Perform this procedure once the pilot is lit and  
ensure that the thermostat is turned to the OFF position.  
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 thermopile wires coming from the pilot to the  
gas valve.  
b. Using the positive (+) test probe, connect the probe to  
the top PP terminal with the red wire.  
c. Connect the negative (-) test probe to the bottom PP  
terminal with the white wire.  
d. The output level should be 550mv ± 50mV. If this level  
is not correct, remove the cap screw and adjust the  
screw in and out to achieve the proper millivolt level.  
Replace cap screw.  
Note: Allow 3 to 5 minutes between flame adjustments to allow the reading to stabilize.

INSTALLATION/OPERATION  
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  
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.  
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 “OIL 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 (range of 0-16 “ w.c. in 0.1” increments) or  
manometer.  
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.  
d.  
The installed pressure gauge should be the same, ±0.1” w.c, as that marked on the data  
plate on the inside door or on the back of the appliance. If the pressure is correct, go to  
step e, if it is not, adjust the pressure as outlined in step d.  
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.  
e.  
When the pressure is correct, replace the regulator adjustment screw cover.
