PROVISIONS MUST BE MADE FOR ADEQUATE AIR SUPPLY TO THE UNIT.
THE UNIT, WHEN INSTALLED, MUST BE ELECTRICALLY GROUNDED IN
ACCORDANCE WITH LOCAL CODES, OR IN ABSENCE OF LOCAL CODES, WITH THE
NATIONAL ELECTRICAL CODE, ANSI/NFPA 70, OR THE CANADIAN
ELECTRICAL CODE, CSA C22.2, AS APPLICABLE.
Ventilating Hood
The range(s) must be installed under a properly designed ventilating hood. The hood should
extend at least 6‖ beyond all sides of the unit. The hood should be connected to an adequate
mechanical exhaust system.
Information on the construction and installation of ventilating hoods may be obtained from the
‗Standard for the Installation of Equipment for the Removal of Smoke and Grease Laden Vapors
from Commercial Cooking Equipment‖, NFPA 96, available from the National Fire Protection
Association, Batterymarch Park, Quincy, MA 02269.
It is also necessary that sufficient room air ingress be allowed to compensate for the amount of
air removed by the ventilating system. Otherwise, a subnormal atmospheric pressure will occur
which may interfere with burner performance or may extinguish the pilot flame. In case of unsat-
isfactory range performance, check with the exhaust fan in the ―OFF‖ position.
Clearances
Adequate clearance must be provided at the side, back, and in the aisle to allow the doors to
open sufficiently to permit the removal of the racks and for serviceability. Adequate clearance for
air openings into the combustion chamber must be provided.

INSTALLATION
Fry Top Ranges
Leveling bolts are at the rear of the range under the Fry Top plate.
Adjust leveling bolts so that the plate is pitched to the front to provide
for grease runoff. Be sure wooden strips have been removed from
below the grease trough.
GAS PRESSURE REGULATOR
GAS CONNECTION
Before connecting the range to the gas supply line, be sure that all new piping has been
cleaned and purged to prevent any foreign matter from being carried into the controls by the gas. In
some cases, filters or drops are recommended. A separate Gas Shut Off Valve must be installed
upstream from the gas pressure regulator adjacent to the range and be located in an accessible
area.
It is important that adequately sized piping be run directly to the point of connection at the
range, with as few elbows and tees as possible. Consult local gas company for proper piping size
and gas pressure.
THIS RANGE IS DESIGNED FOR USE WITH A GAS PRESSURE REGULATOR. THE
REGULATOR SUPPLIED WITH THIS UNIT MUST BE USED.
FOR NATURAL GAS: This gas pressure regulator is factory adjusted for 6.0‖ W.C.
manifold pressure. The rated inlet pressure to the regulator is 1/2psig (3.45kPa).
FOR PROPANE GAS: This gas pressure regulator is factory adjusted for 10.0‖ W.C.
manifold pressure. The rated inlet pressure to the regulator is 1/2 psig (3.45kPa).
Unless otherwise specified, the range is equipped with fixed orifices for use with a
manifold pressure of 6.0” water column for natural gas and 10.0” water column for
propane gas.

8
INSTALLATION
PIPE JOINT COMPOUND OR THREAD SEALANT THAT IS USED
SHOULD BE RESISTANT TO ACTION OF LIQUEFIED PETROLEUM
GASES.
Install the gas pressure regulator with gas flowing as indicated by the arrow on the
regulator. Use pipe compound or thread sealant and carefully thread regulator to pipe so that
there is no cross-threading, etc, which could cause leakage.
Apply wrench only to the flat areas around the pipe tapping at the end being threaded to
the pipe to avoid possible damage to the regulator body which could result in leakage.
Connect the gas supply line from the Service Gas Shut Off valve to the inlet side of the gas
pressure regulators using 3/4‖ pipe. If flexible or semi-flexible connectors are used, an AGA listed
flexible connector with an I.D. equal to 3/4‖ pipe must be used. DO NOT USE A DOMESTIC
APPLIANCE TYPE GAS FLEXIBLE CONNECTOR. Avoid kinks or sharp bends that could restrict
gas flow.
Turn Gas Shut Off Valve ―ON‖ and immediately check carefully for gas leaks. Do this
before attempting to operate the range.
TEST ALL PIPE JOINTS FOR LEAKS BEFORE OPERATING RANGE. THIS INCLUDES
ALL GAS CONNECTIONS THAT MAY HAVE LOOSENED DURING SHIPMENT. USE A
RICH SOAP SOLUTION (OR OTHER ACCEPTED LEAK TESTER) AROUND ALL PIPE
CONNECTIONS AND ALL OTHER JOINTS. DO NOT USE AN OPEN FLAME.
ABSOLUTELY NO LEAKAGE SHOULD OCCUR, OTHERWISE THERE IS A DANGER OF
FIRE OR EXPLOSION DEPENDING UPON CONDITIONS. NEVER USE IF LEAKAGE IS
DETECTED.

PILOT ADJUSTMENT—TOP BURNERS
OVEN TOP: The front and rear pilots are controlled by one valve. To adjust pilot, turn ad-
justing screw counterclockwise to increase or clockwise to decrease pilot flame. Adjust flame to a
point where only a trace of yellow tip remains.
FRY TOP and HOT TOP: Each pilot is controlled by a pilot valve. Turn adjusting screw until
pilot flame is 1/2‖ high.
BURNER ADJUSTMENT
The efficiency of the range depends on a delicate balance between the supply of air and
the volume of gas so that complete combustion is achieved. Whenever this balance is disturbed,
poor operating characteristics occur.
The air supply is controlled by an air shutter on the front of the burner. The air shutter
openings should be increased until the flame on the burner begins to ―lift‖. The air shutter should
then be closed slightly and locked in place. A yellow streaming flame indicated insufficient air. This
condition can be corrected by increasing the air shutter opening.
FRY TOP AND OVEN THERMOSTATS
The by-pass (minimum burner flame) has been adjusted at the factory and should require
no further adjustment.
THE BY-PASS FLAME MUST BE RECHECKED WHEN PERFORMING CHECKOUT OF
RANGE PRIOR TO PLACING EQUIPMENT IN SERVICE. THE BY-PASS MUST BE SET
CAREFULLY AND ACCURATELY. REFER TO SERVICE SECTION OF THIS MANUAL
FOR PROPER PROCEDURE.
