INSTALLATION
The Montague gas ranges are manufactured for use with the type of gas indicated on the nameplate.
The Montague heavy duty gas ranges are produced with the best possible material and workmanship.
PROPER INSTALLATION IS ESSENTIAL FOR SAFE AND EFFICIENT TROUBLE-FREE OPERATION.
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 AND/OR
INJURY TO THE OPERATOR.
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 servicing 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, Section 1.4.
B. The installation of electrical wiring from the electric meter, main control box or service outlet to
the electric appliance. Qualified installation personnel must be experienced in such work, be
familiar with all precautions required and have complied with all requirements of state and local
authorities having jurisdiction. Reference: National Electric Code, ANSI/NFPA No. 70.
READ CAREFULLY AND FOLLOW THESE INSTRUCTIONS
THE RANGE(S) MUST BE INSTALLED IN ACCORDANCE WITH LOCALCODES, OR
IN THE ABSENCE OF LOCAL CODES, WITH THE NATIONAL FUEL GAS CODE,
ANSIZ223.1-LATESTADDENDA,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 UNIT.

INSTALLATION
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 No. 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 unsatisfactory range performance, check with the exhaust fan in the "OFF"
position.
CLEARANCES
Adequate clearance must be provided in 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.
CLEARANCES

ASSEMBLY
Uncrate range as near to final location as possible. Remove all shipping wire from
burners and all packing material and accessories from oven interior. Then assemble as
follows:
1. Screw the adjustable feet of the legs in all the way. Then tightly screw the
complete leg assembly into the mounting holes at each corner of the range.
If the unit is intended for curb installation, no legs are provided. The curb
must be noncombustible material.
2. Install door handle and secure with screws that are provided. Observe "UP"
marking on handle for correct orientation.
3. If top castings are removed, identify castings so they are replaced in the same
position and on same range as when received from the factory.
SETTING IN PLACE
BATTERY ARRANGEMENT
FLOOR MOUNTED RANGES:
1. Place the first range in the exact position it will occupy in the battery.
2. Using a carpenter's level, level range from front to rear and side to side.
Adjust as follows:
FLOOR INSTALLATION ON LEGS: Adjust by turning foot on adjustable leg.
CURB INSTALLATION ON LEGS: Place shim under the low side. This
operation is important since variation in floor and curbs are common. Unless
ranges are level, difficulty will be encountered in aligning the gas ranges are
level, difficulty will be encountered in aligning the gas supply manifold and
the ranges will not butt together tightly.
3. Remove the upper valve panel from range.
4. Move the next range into position.
5. Engage union nut on manifold with male fitting on next range and draw up
union nut hand tight. Be sure appliances butt together both front and rear.
If manifolds do not align, then ranges are not level. In extreme cases, it may be
necessary to loosen manifold bolts and adjust.
6. Continue leveling and connecting gas supply manifolds together until all
appliances in battery are connected.
7. Tighten front manifold pipe union gas tight. Use back up wrench to prevent
manifold from rotating. FAILURE TO DO THIS MAY RESULT IN DAMAGE
TO PILOTS AND GAS VALVES.
INSTALLATION

MODULAR RANGES:
Assemble modular base and set in place. Adjust feet as explained above. Connect ranges
as shown for battery arrangement.
FRY TOP RANGES:
Fry Top Plate Adjustment: 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. (See Fig. 1)
HIGH SHELVES AND SALAMANDER BROILERS:
Lift high shelf or broiler above the range and slide legs into position. (See Fig.2)
GAS APPLIANCE REGULATOR
A GAS APPLIANCE PRESSURE REGULATOR SUITABLE FOR THE BATTERY
APPLICATION AND ADJUSTED FOR THE MANIFOLD PRESSURE SPECIFIED
ON THE RANGE NAMEPLATE MUST BE FURNISHED BY THE INSTALLER AT
THE TIME OF INSTALLTION.
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.

The gas pressure regulator furnished by the installer must comply with the following:
1. The pressure regulator(s) must have a maximum regulation capacity for the total connected
load.
2. The pressure regulator(s) installed must be listed by a nationally recognized testing agency.
3. The pressure regulator(s) must have a pressure adjustment range to allow adjustment to the
manifold pressure on the appliance rating plate.
4. Unless the manifold pressure on all connected appliances is the same, a separate pressure
regulator must be supplied for each appliance(s) having differing manifold pressures.
GAS CONNECTION
Before connecting the range battery 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 recommend. A separate Gas Shut off Valve must be installed
upstream from the gas pressure regulator adjacent to the range battery and located in an accessible
area.
WARNING: CAP ALL UNUSED OPEN ENDS OF THE GAS SUPPLY MANIFOLD.
It is important that adequately sized piping be run directly to the point of connection at range
battery with as few elbows and tees as possible. Consult local gas company for proper piping size
and gas pressure.
PIPE JOINT COMPOUND OR THREAD SEALANT THAT IS USED SHOULD BE
RESISTANT TO ACTION OF LIQUEFIED PETROLEUM GASES.
Turn Gas Shut Off Valve "ON" and immediately check carefully for gas leaks. Do this before
attempting to operate the range battery.

TEST ALL PIPE JOINTS FOR LEAKS BEFORE OPERATING RANGE(S).
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
OPEN TOP: The front and rear pilots are controlled by one valve. To adjust pilot, turn adjusting
screw counter-clockwise to increase or clockwise to decrease pilot flame. Adjust flame to a point
where only a trace of yellow tip remains.
HOT TOP & FRY 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 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 indicates insufficient air. This condition
can be corrected by increasing the air shutter opening.
SERVICE

FRY TOP AND OVEN THERMOSTATS
The bypass (minimum burner flame) has been adjusted at factory and should require no further
adjustment if the gas manifold pressure is correct.
THE BYPASS FLAME MUST BE RECHECKED WHEN PERFORMING CHECKOUT OF
RANGE PRIOR TO PLACING EQUIPMENT IN SERVICE. THE BYPASS MUST BE SET
CAREFULLY AND ACCURATELY. REFER TO SERVICE SECTION OF THIS MANUAL FOR
PROPER PROCEDURE.
