INSTALLATION
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. 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/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.
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/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. Remove the two self-drilling screws from the top, back area of the appliance.
b. 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.
Installation Clearances
The clearances shown below are for combustible and non-combustible installations and will allow for safe and
proper operation of your appliance.
Combustible
Construction
Back 6 in. (15 cm) 0
Sides 6 in. (15 cm) 0
Floor 6 in. (15 cm) 6 in. (15 cm)
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.
NonCombustible

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 conne ct i ons 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 website at www.csa-international.org.
