INTRODUCTION

U.S. Range manufactures the “Regal” Griddles in widths from
18” to seven feet, manually or thermostatically controlled,
with the option of grooved griddle surface, installation in all
cases is similar.

All griddles are shipped completely assembled, with the
grease can (and drip pan, when applicable) and pressure
packed on top of the unit.

Griddle burners are tied to the frame at the rear to stop
vibration during shipment and open burner heads, (when
applicable) are tied to the burner hangers. All griddles are
inspected at the factory before shipping.

Uncrating

After uncrating, immediately check the equipment for visible
signs of shipping damage.

If such damage has occurred, do not refuse shipment, but
contact the shipper and le the appropriate freight claims.

Rating Plate

The rating plate is attached to the lower front of the frame
end, either on the left or right side of the unit.

When corresponding with the factory or your local
authorized factory service center regarding service problems
or replacement parts, be sure to refer to the particular unit
by the correct model number (including the prex and sux
letters and numbers) and the warranty serial number. The
rating plate axed to the unit contains this information.

Other information on this plate is the BTU/hr input to the
burners, outlet gas pressure in inches WC, and whether
oriced for natural or propane gas.

WARNING All U.S. Range “Regal” Griddles must be connected
only to the type of gas identied on the rating plate!
Installation must be in accordance with ANSI 283.11 (latest
edition) of the American national Standards Institute, Inc.

INSTALLATION

Clearances

The appliance area must be kept free and clear of all
combustibles.

These units are design-certied for the following
installations:

1. Intended for other than household use.

2. For use in non combustible locations only.

3. For use with 6” (minimum) legs.

Type of Construction

Minimum Clearance

Non-Combustible

Rear 0”

Sides 0”

Positioning and Setup

Some form of mechanical assistance will be required to
position these griddles, as the smallest weighs almost 200
pounds with the larger sizes near a 1000. After the griddle
is in position, place a carpenter’s spirit level diagonally on
the surface of the griddle plate and level to the corner. Move
the level to the opposite diagonal and re-level, then double
check the width with the level in the rst position. Each leg
features an adjustable foot for leveling purposes.

With the appliance leveled, the griddle plate itself can be
sloped to the front, if desired. Adjusters are built into the rear
of the frame, just under the plate and several inches in from
each side. Do not use these adjusters to level the appliance.
They lift only the rear of the griddle plate and do not aect
the leveling of the complete unit.

INSTALLATION Continued

Air Supply and Ventilation

The area around the appliance must be kept clear to avoid
any obstruction to the ow of combustion and ventilation
air, as well as, for ease of maintenance and service.

Means must be provided for any commercial, heavy-duty
cooking appliance to exhaust combustion waste products to
the outside of the building. Usual practice is to place the unit
under an exhaust hood; the minimum should be an exhaust
fan mounted above the unit Filters and drip troughs should
be part of any industrial hood, but consult local codes before
construction and installing a hood.

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 pilot or burner performance and be hard to diagnose.
Air movement should be checked during installation; if
pilot/burner outage problems persist, make-up air openings
or baes may have to be provided in the room.

Electrical Connection

All electrical controls in the units are pre-wired at the factory.
Each griddle requires a 120-volt, 1 phase, 0.5 amps, and
60 Hz service line, which must be electrically grounded in
accordance with local codes, or in the absence of local codes,
with the National Electrical Code, ANSI/NFPA 70, OR THE
Canadian Electrical Code, CSA C22.2, as applicable.

Electrical diagrams are attached to the lower front of the
frame end, either in the left or right side of the unit.

NOTE: The gas supply (service) line must be the same size or
greater than the inlet line of the appliance. U.S. Range “Regal”
Griddles use a 3/4” NPT inlet. Sealant on all pipe joints must
be resistive to LP gas.

Statutory Regulations

Safe and satisfactory operation of your equipment depends,
to a great extent, on its proper installation. Installation must
conform to local codes or, in the absence of local codes with
the National Fuel code, ANSI Z223.1, Natural Gas Installation
Code, CAN/CGA-B149.1, or the Propane Installation Code,
CAN/CGA-B149.2, as applicable, including:

1. The appliance and its individual shuto valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 psi (3.45 kPa).

2. The appliance must be isolated from the gas supply
piping system by closing its individual manual shuto
valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than 1/2
psi (3.45 kPa).

Manual Shut-O Valve

This installer-supplied valve must be installed in the gas
service line ahead of the appliance and regulator in the gas
stream and in a position where it can be reached quickly in
the event of an emergency.

Pressure Regulator

WARNING

Electrical Grounding Instructions: This appliance is
equipped with a three-prong grounding plug for your
protection against shock hazard and should be plugged
directly into a properly grounded, three hole receptacle.

Gas Supply

1. Installation of the equipment should be made by a
licensed plumber.

2. A gas shut-o valve must be installed in the gas supply
line ahead or the appliance for safety and for ease of
future service.

3. A gas pressure regulator must be installed at the
appliance prior to connecting the equipment to the gas
line. Failure to install a regulator will void the equipment
warranty.

All heavy-duty, commercial cooking equipment must have
a pressure regulator in the incoming service line for safe and
ecient operation, since service pressure may uctuate with
local demand. The manual shut-o valve is normally supplied
by the installer, but pressure regulators are shipped from U.S.
Range with every Griddle

Regulators are pre-set at the factory for 5” WC (natural gas)
or 10” WC (propane) according to the customer’s ordering
instructions.

Prior to connecting the regulator, check the incoming line
pressure, as these regulators can withstand a maximum
pressure of 1/2 psi (14” WC). If the Line pressure is beyond
this limit, a step-down regulator will be required. Double­check the arrow forged onto the bottom of the regulator
body which shows gas ow directions; it should point
downstream to the appliance. The red air-vent cap is part of
the regulator and should not be removed unless local codes
require external venting.

INSTALLATION Continued

Regulators can be adjusted in the eld, but it is
recommended that they not be tampered with unless that
part is known to be out of adjustment or serious pressure
uctuations are found to exist and can be solved no other
way. Any adjustments to regulators must be made by
qualied service personnel with proper test equipment.

If a vent line from the gas appliance pressure regulator is
used, it should be installed to the outdoors in accordance
with local codes, or in the absence of local codes with the
National Fuel Gas Code, ANSI Z223.1, Natural Gas Installation
Code, CAN/CGA-B149.1 or the Propane Installation Code
CAN/CGA-B149.2, as applicable.

WARNING Failure to install a pressure regulator will void
the equipment warranty!

Rigid Connections

Double-check any installer-supplied intake pipes visually
and clear any dirt particles, threading chips, or other foreign
matter before installing in a service line. Those particles will
clog orices when gas pressure is applied.

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

Flexible Couplings & Connectors.

If the unit is to be installed with exible couplings and/or
quick-disconnect ttings, 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 /CSA 6.16, and a quick-disconnect
device that complies with the Standard for Quick-Disconnect
Devices for Use With Gas Fuel, ANSI Z21.41 / CSA 6.9, and
adequate means must be provided to limit the movement of
the appliance without depending on the connector and the
quick-disconnect device or its associated piping. To limit the
appliance movement, a 1” hole is provided on each side of
the back panel for attaining a restraining device.

Manual Pilot Valve

All burners are equipped with constant-burning pilots. These
should be manually lighted immediately after the gas is
turned on and the system is checked for leaks.

Griddle burners are tubular steel “U” shaped and individually
piloted. This pilots can be reached with a long taper through
the observation/adjustment openings in the valve cover
between the burner control knobs or thermostats. The pilot
valve with adjustment screw is in the same opening.

Testing and Adjustments

Check all gas connections for leaks using a soapy solution
before lighting any pilots. DO NOT USE OPEN FLAME
TO CHECK FOR LEAKS! Putting open ame beside a new
connection is not only dangerous, but will often miss small
leaks that a soapy solution would nd.

All U.S. Range appliances are adjusted and tested before
leaving the factory, eectively matching them to sea
level conditions. Adjustments and calibrations to assure
proper operation may be necessary on installation to meet
local conditions, low gas pressure, dierences in altitude;
variations in gas characteristics, to correct possible problems
caused by rough handling or vibration during shipment, and
are to be performed only by qualied service personnel.

These adjustments are the responsibility of the customer,
installer and/or dealer and are not covered by the U.S. Range
warranty.
