OPERATION INSTRUCTIONS

Operation of this equipment must be performed by qualified or authorized personnel who have read and
are familiar with the functions of the equipment.

MAINTENANCE INSTRUCTIONS

RATING PLATE

The rating plate is located in front of the range below the oven section. Information on this plate
includes the model, serial number, BTU / hour input of the burners, operating gas pressure in inches
WC, and whether the appliance is orificed for natural or propane gas. Pilot lighting instructions (ovens
only) are also located in the same area. The Salamander broiler, or Cheesemelter (if provided) are
supplied with their own rating plates.

When communicating with factory about a unit or requesting for special parts or information, rating plate
data is essential for proper identification.

APW WYOTT COOKING APPLIANCES MUST BE CONNECTED ONLY TO THE TYPE OF GAS

IDENTIFIED ON THE RATING PLATE

CLEARANCES

The appliance area must be kept free and clear of all combustibles.
The clearances from combustible and non combustible construction of ranges and range mounted

salamander broiler or cheese melter are as follows.

If legs or casters are not used, the appliance must extend 2" beyond the front edge of a non
combustible curb or platform.

HIGH SHELF ASSEMBLY

Mount the high shelf Assembly to the range with # 10 sheet metal screws.
If a Salamander broiler / Cheese melter is to be mounted on Range, read installation instructions

for Salamander / Cheese melter before installing the High Shelf. Care must be taken to ensure
gas supply piping and / or gas supply regulator is not exposed to exhaust gases, or elevated
temperatures.

LEVELLING (Ranges equipped with Ovens)

A carpenter’s spirit level should be used and placed on the oven’s center baking rack and or across the

range top and the unit leveled from front to back and side to side. If it is not level, cakes, casseroles and
any other liquid or semi liquid batter will not bake evenly, burner combustion may be erratic, and the
unit will not function efficiently.

If the floor is smooth and level, the appliance may be further leveled with adjustment in the foot of the
leg. Units with castors require adjustment with shims. A unit will probably not return to the same position
after being moved, requiring relevelling after each and every move.

AIR SUPPLY & VENTILATION

The area in front of, around and above the appliance must be kept clear to avoid any obstruction of the
flow of combustion and ventilation air. Adequate clearance must be maintained around the appliance for
easy servicing.

Provision should be made for any commercial, heavy duty cooking appliance exhaust combustion
waste products to the outside of the building. Usual practice is to place the appliance under an exhaust
hood, which should be constructed in accordance to the local codes.

Strong exhaust fans in this hood or in the overall air conditioning system can produce a slight vacuum in
the room and / or cause air drafts, either of which can interfere with the pilot or burner performance and
could be difficult to diagnose. Air movement should be checked during installation. Air openings or
baffles may have to be provided in the room, if pilot or burner outrage problem persists.

GAS CONNECTION

The gas supply (service) line must be the same size or greater than the inlet line of the appliance.
APW wyott ranges and ovens use a ¾" NPT inlet. Sealant on all pipe joints must be resistive to LP gas.

MANUAL SHUT OFF VALVE

This installer supplied valve must be in the gas service line ahead of the appliance regulator in the gas
stream and in a position accessible in the event of an emergency.

PRESSURE REGULATOR

Commercial cooking equipment must have a pressure regulator on the incoming service line for safe
and efficient operation, since service pressures may fluctuate on local demand. A pressure regulator is
packed inside every APW wyott range.

Failure to install the pressure regulator will void the appliance warranty.

The regulators supplied along with APW wyott appliances, will have ¾" inlet/outlet openings and are
adjusted at the factory for 5" WC (natural gas) or 10" WC (propane gas) depending on customer's
ordering instructions.

Prior to connecting the regulator, check the incoming line pressure, as these regulators can only
withstand a maximum pressure of ½'' psi (14" WC). If the line pressure is beyond this limit, a step down
regulator will be required.

The arrow shown on the bottom of the regulator body shows the gas flow direction, it should point
downstream to the appliance. The red air vent cap on the top is part of the regulator and should not be
removed.

Any adjustments to the regulator should be made by qualified service personnel only with the proper
equipment.

CONNECTIONS

Please check installer supplied intake pipes visually and / or blow them with compressed air to clear
any dirt particles, threading chips or any other foreign matter before installing a service line. When gas
pressure is applied, these particles could clog orifices.

All connections must be sealed with a joint compound suitable for LP gas, and all connections must be
tested with a soapy water solution before lighting any pilots.

FLEXIBLE COUPLINGS, CONNECTOR AND CASTERS

CAUTION: When lighting pilots and checking for leaks, do not stand with your

face close to the combustion chamber.

For an appliance equipped with casters, the installation shall be made with a connector that complies
with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 or Connectors for
Moveable Gas Appliances, CAN/CGA-6.16, and a quick disconnect device that complies with the
Standard for Quick Disconnect Devices for Use With Gas Fuel, ANSI Z21.41, or Quick Disconnect
Devices for Use With Gas Fuel, CANI-6.9.

If disconnection of the restraint is necessary, make sure to reconnect restraint after the appliance has
been returned to its originally installed position. Domestic gas or water connectors are not suitable.

Restraining device may be attached to the back frame / panel of the unit.
If the appliance is to be installed with casters, a flexible connector must be used and the same ANSI

standards apply. Locking front casters are provided to limit the movement of the appliance without
depending on the connector or associated piping. A suitable strain relief must be installed with a flexible
connector.

All connections must be sealed with a joint compound suitable for LP gas and all connections must be
tested with soap water solution before lighting pilots.

INITIAL PILOT LIGHTING

All APW wyott appliances are adjusted and tested before leaving the factory, effectively matching them
to sea level conditions. Adjustments and calibrations to assure proper operation may be necessary on
installation to meet local conditions, low gas characteristics; correct possible problems caused by rough
handling or vibration during shipment and are to be performed only by qualified service personnel.
These adjustments are the responsibility of the customer and / or dealer and are not covered by our
warranty.

Check all gas connections for leaks with a soapy water solution before lighting any pilots.

DO NOT USE ANY FLAME TO CHECK FOR LEAKS

Before lighting any pilots, make sure that burner valves and thermostats are turned "OFF".

TOP BURNERS / RAISED GRIDDLE / BROILER

All top section burners are equipped with constant burning pilots. These are to be manually lighted
immediately after the gas is turned on and the system is checked for leaks. Burner pilots are provided
for each burner and can be rechecked for proper adjustment. All adjustments can be made with a screw
driver to the brass pilot valve accessible through the valve cover.

GRIDDLE

The pilot should be lighted immediately after the gas is turned on and the system is checked for leaks.
The pilot can be reached with a long match through the valve cover, or by lifting the plate upward and
accessing through the top. Adjustment of the pilot flame can be made with a screwdriver to the pilot
valve, accessible through the valve cover.
