INSTALLATION
The MONTAGUE gas stock pot ranges are manufactured for use with the type of gas indicated
on the nameplate.
The MONTAGUE gas stock pot ranges are produced with the best possible materials and
workmanship. PROPER INSTALLATION IS ESSENTIAL FOR SAFE AND EFFICIENT
TROUBLE-FREE OPERATION.
Qualified installation personnel are individuals, a firm, corporation, or company which either in
person or through a representative are engaged in, and are responsible for:
A. The installation or replacement of gas piping or the connection, installation, repair or servic-
ing of equipment, who is experienced in such work, familiar with all precautions required,
and has complied with all requirements of state or local authorities having jurisdiction.
Reference: National Fuel Gas Code Z223.1-1984, Section 1.4.
THE INSTALLATION INSTRUCTIONS CONTAINED HEREIN ARE FOR THE USE OF
QUALIFIED INSTALLATION AND SERVICE PERSONNEL ONLY. INSTALLATION OR
SERVICE BY OTHER THAN QUALIFIED PERSONNEL MAY RESULT IN DAMAGE TO THE
OVEN/INJURY TO THE OPERATOR.
READ CAREFULLY AND FOLLOW THESE INSTRUCTIONS
THE RANGE(S) MUST BE INSTALLED IN ACCORDANCE WITH THE LOCAL CODES,
OR IN THE ABSENCE OF LOCAL CODES, WITH THE NATIONAL FUEL GAS CODE,
ANSI Z223.1-1984, INCLUDING:
1. The appliance and its individual shutoff 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 psig. (3.45 kPa).
2. The appliance must be isolated from the gas supply piping system by closing
its individual manual shutoff valve during any pressure testing of the gas
supply piping system at test pressure equal to or less than 1/2 psig. (3.45 kPa).
PROVISIONS MUST BE MADE FOR ADEQUATE AIR SUPPLY TO THE
RANGE(S).

4
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 ventilation 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 No. 96-1987, available from the National Fire
Protection Association, Batterymarch Park, Quincy, MA 02269.
It is also necessary that the sufficient room air ingress be allowed to compensate for the amount
of air removed by the ventilation system. Otherwise, a subnormal atmospheric pressure will occur
which may interfere with burner performance or may extinguish the pilot flame. In case of unsatis-
factory oven performance, re-check performance with the exhaust fan turned “OFF”.
Clearances
Adequate clearance must be provided in the aisle and at the side and back 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
MINIMUM CLEARANCE FROM COMBUSTIBLE MATERIAL AND
NONCOMBUSTIBLE MATERIAL
STOCK POT RANGE(S):
BACK: 6”
SIDE: 6”
CAUTION!
DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATION AIR TO THE
BROILER(S). KEEP THE APPLIANCE AREA FREE AND CLEAR FROM
COMBUSTIBLES.

INSTALLATION
ASSEMBLY
Uncrate range as near to final location as possible. Remove all shipping wire from burner(s) and
all packing material and accessories from unit. Screw the adjustable feet of the legs in the way.
Using a carpenter’s level, adjust the level of the range from front to rear, and from side to side by
turning the foot on the adjustable leg.
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 up-
stream from the gas pressure regulator adjacent to the range and be located in an accessible ar-
ea.
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 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 fro 4.0” W.C. manifold
pressure. The rated inlet pressure to the regulator is 1/2 psig. (3.45 kPa)
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. (3.45 kPa)
Unless otherwise specified, the range is equipped with fixed orifices for use with a
manifold pressure of 4.0” water column for natural gas and 10.0” water column for
propane gas.

INSTALLATION
PIPE JOINT COMPOUND OR THREAD SEALANT THAT IS USED
SHOULD BE RESISTANT TO ACTION OF LIQUEFIED PETROLEUM.
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 regulator using 1/2” pipe. If flexible or semi-flexible connectors are used, an AGA listed
flexible connector with an I.D. equal to 1/2” 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
CONENCTIONS 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.

INSTALLATION
PILOT ADJUSTMENT—TOP BURNERS
The standing lighter is controlled by a pilot valve. Turn adjusting screw counterclockwise to
increase or clockwise to decrease pilot flame. Adjust flame to a point where only a trace of yel-
low tip remains.
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.

MAINTENANCE
CARE AND CLEANING
The complete range should be given a periodic general cleaning. Lint and grease
suspended in the air tend to collect in air passages. Therefore, all flueways, air passages and
opening, burner ports, primary air openings, etc., should be periodically cleaned to prevent
clogging.
EXTERIOR
PAINTED SURFACE: Allow equipment to cool after use and wash with a mild detergent or
soap solution. Dry thoroughly with a clean cloth.
STAINLESS STEEL SURFACE: To remove normal dirt, grease, or product residue from
stainless steel, use ordinary soap and water (with or without detergent) applied with a sponge or
cloth. Dry thoroughly with a clean cloth.
To remove grease and food splatter, or condensed vapors that have baked on the
equipment, ally cleanser to a damp cloth or sponge and rub the cleaner on the metal in the
direction of the polished lines on the metal. Rubbing cleanser as gently as possible in the
direction of the polished lines will not mar the finish of the stainless steel. NEVER RUB WITH A
CIRCULAR MOTION. Soil and burnt deposits which do not respond to the above, procedure can
usually be removed by rubbing the surface with SCOTCH-BRITE scouring pads or STAINLESS
scouring pads. DO NOT USE ORDINARY STEEL WOOL as any particles left on the surface will
rust and further spoil the appearance of the finish. NEVER USE A WIRE BRUSH, STEEL
SCOURING PADS (EXCEPT STAINLESS), SCRAPER, FILE OR OTHER STEEL TOOLS.
Surfaces which are marred collect dirt more rapidly and become more difficult to clean. Marring
also increases the possibility of corrosive attack.
To remove heat tint: Darkened areas sometimes appear on stainless steel surfaces where the
area has been subjected to excessive heat. These darkened areas are caused by thickening of
the protective surface of the stainless steel and are not harmful. Heat tint can normally be
removed by the foregoing, but tint which does not respond to this procedure calls for a vigorous
scouring in the direction of the polish lines, using SCOTCH-BRITE scouring pads or a
STAINLESS scouring pad in combination with a powdered cleanser. Heat tint action may be
lessened by not applying or by reducing heat to equipment during slack periods.

MAINTENANCE
OPEN TOP SECTION
DAILY: Wipe top with burlap or grease absorbing material to remove spillovers,
grease, etc., before they burn into the surface.
WEEKLY: Brush burner head with a stiff wire brush and clean clogged ports with a stiff
wire or ice pick.
Excessive grease build up may be removed from burner(s) by soaking in a solution of
washing soda. Dry burners by inverting on rack in a low temperature oven.
