INSTALLATION, OPERATION AND CARE OF
STOCK POT RANGE
GENERAL
Stock pot ranges are designed for commercial use only and feature fast, efficient gas heat.
Each burner is controlled by an adjustable gas valve. Heavy-duty, cast iron top grate(s) are
easily removed for cleaning when cool. A grease drawer is provided to collect fat run-off; it
opens to the front for inspection or drain-off.

UNPACKING INSTALLATION
This stock pot was inspected before leaving the factory. The carrier assumes full responsibility for the
safe delivery upon acceptance of the shipment. Check for possible shipping damage immediately after
receipt.
If the stock pot is found to be damaged, complete the following steps:
1. Carrier must be notified within 5 business days of receipt.
2. Carrier’s local terminal must be notified immediately upon discovery (note time, date, and
Who was spoken to), and follow up and confirm with written or electronic communication.
3. All original packing materials must be kept for inspection purposes.
4. The stock pot can not have been moved, installed, or modified.
Remove all packing material and protective plastic from the surfaces of the unit. Before
installing, verify that the type of gas (natural or propane) and the clearance dimensions agree
with the specifications on the rating plate which is located at the back of the stock pot.

4
LOCATION
The installation location must be kept free and clear of combustibles. Do not obstruct the
flow of combustion and ventilation air. DO NOT install the stock pot adjacent to open burners or
fryers.
Sufficient air should be allowed to enter the room to compensate for the amount of air removed
by any ventilating system and for combustion of the gas burners. Do not obstruct the air flow
into and around the appliance. Do not obstruct the flow of flue gases through and above the
stock pot top grate. Position the stock pot in its final location. Check that there are sufficient
clearances to service the stock pot and to make the required gas supply connection(s).
Provide 24" clearance at the front for cleaning, maintenance, service and proper operation.

NOTE:In the Common wealth of Massachusetts
All gas appliances vented through a ventilation hood or exhaust system equipped with a
damper or with a power means of exhaust shall comply with 248 CMR.
3. NFPA Standard #96 Vapor Removal from Cooking Equipment, latest edition, available from
the National Fire Protection Association, Battery march Park, Quincy, MA02269.
In Canada:
1. Local codes.
2. CAN/CSA-B149.1 Natural Gas Installation (latest edition)

LEG INSTALLATION
The stock pot range is shipped without the legs attached. The stock pot
range must not be operated without the legs attached to the unit.
1.Remove cast iron grate and burners from chassis.
2.Turn chassis up side down and locate the leg plate to a light the four screw holes (Fig.1).
3.Screwlegs plate with four screws on the bottom until tight (Fig.2). Use a pipe or strap
wrench with a towel (so as not to scratch leg) if needed to firmly tighten legs.
Fig. 1 Fig. 2
4. Continue process until all legs are installed. Single stock pots will have four legs and
double stock pots will have six legs.
5. Return stock pot to upright position; reinstall burners and grates.

GAS PRESSURE REGULATOR INSTALLATION
Gas regulator pressure is preset at 5”Water Column (W.C.) for natural gas, and 10”W.C.
For propane gas. Minor adjustments maybe required based on site specific gas pressure.
Install the regulator as close to the stock pot on the gas supply line as possible. Make sure that
the arrow on the underside of the regulator is oriented in the direction of gas flow to the stock pot
(Fig. 3) and the regulator is positioned with the vent plug and adjustment screw upright(Fig.4).
Fig.3 Fig.4
The minimum supply pressure (up stream of the regulator) should be 7-9”W.C. for natural gas
and 11-12” W.C. for propane gas. At no time should the hot plate be connected to supply
pressure greater than ½ psig (3.45kPa) or 14”W.C.
LEVELING
The Stock pot Range is equipped with legs. Turn the feet at the bottom of the legs in or out to
level the Stock pot Range in the final installed location.
VENTILATION HOOD
The stock pot should be installed under a suitable ventilation hood. For safe operation and
proper ventilation, keep the space between the stock pot and vent hood free from any
obstructions.

NOTICE
GAS CONNECTION
The data plate on the rear of the stock pot indicates the type of gas your unit is equipped to burn.
DO NOT connect to any other gas type.
Gas supply connections and any pipe joint compound must be resistant to the action
of propane gases.
Purge the supply line to clean out any dust, dirt, or any foreign matter before connecting the line
to the unit.
Codes require that a gas shut-off valve be installed in the gasline ahead of the stock pot. The
gas supply line must be at least the equivalent of ¾”iron pipe.
A pressure regulator is supplied and must be installed outside of the broiler when making the
gas supply connection. Standard orifices are set for 5"WC (Water Column) for Natural Gas
10"WC (Water Column) for Propane. Use the
1
/
8
”pipe tap on the burner manifold for checking
pressure. Make sure the gas piping is clean and free of obstructions, dirt, and piping
compound.
An adequate gas supply is necessary. Under sized or low pressure lines will restrict the volume
of gas required for satisfactory performance. A minimum supply pressure of 7" W.C. for natural
gas and 11"W.C. for propane gas is recommended. With all units operating simultaneously,
the manifold pressure on all units should not show any appreciable drop.
When testin the gas supply piping system, if test pressures exceed ½ psig (3.45kPa), the stock
pot and its individual shut off valve must be disconnected from the gas supply piping system.
When test pressures are ½ psig (3.45kPa) or less,the stock pot must be isolated from the gas
supply piping system by closing its individual manual shut-off valve during any pressure testing
of the system.
Prior to lighting, check all joints in the gas supply line for leaks. Use
soap and water solution. Do not use an open flame.
OPERATION
The stock pot range and its parts are hot. Use care when operating,
cleaning or servicing the stock pot range.
CONTROLS
The burner is in two sections, controlled by two heavy duty infinite control valves. The center
“Star”section (Fig.6) is on separate burner with an input of 40,000BTU/hr. It is controlled by
the right burner valve knob. The outer circle of the burner (Fig. 6) is the other separate
40,000BTU/hr input burner, controlled by the left burner valve knob.
These two separate burners provide heat flexibility.With one burner off and the second burner
set low, up to both burners full on, you can move from low simmer on up to 80,000 BTU/hr input.

LIGHTING INSTRUCTIONS
1. Turn all burner valves to OFF position and wait 5 minutes.
2. Turn gas shut off valve ON.
3. Light standing pilot with a lit taper (see Fig 6). Adjust pilot to ¼” high flame, if necessary,
by turning pilot valve adjusting screw (see Fig. 5) counterclockwise to increase or
clockwise to decrease flame.
4. Turn burner valve to ON position.
5. If pilot does not light, turn main gas supply OFF and repeat steps 1 through 4.
TO COMPLETELY SHUT DOWN THE BURNERS AND PILOT LIGHTS
For complete shut down: Turn the main gas supply valve OFF.
CLEANING
Top grate (s) may be immersed in strong commercial cleaning compound overnight. In the
morning, rinse with hot water to remove any residues of cleaning compound. Thoroughly dry
and apply a light coating of cooking oil to prevent rusting.
Stainless steel surfaces maybe cleaned using damp cloth with mild detergent and water
solution. Places where fat, grease, or food can accumulate must be cleaned regularly.
The grease drawer should be emptied regularly when cool.

MAINTENANCE
The stock pot range and its parts are hot. Use care when operating,
cleaning or servicing the stock pot range.
LUBRICATION
All valves must be checked and lubricated periodically. At the first sign of sticking, valves should
be lubricated by a trained technician using high temperature grease. Check with your service
agency for details.
