INSTALLATION

The MONTAGUE gas ranges manufactured for use with the type of gas indicated on the name­plate.

The Montage heavy duty gas counter ranges are produced with the best possible materials and
workmanship. PROPER INSTALLATION IS ESSENTIAL FOR SAFE AND EFFICIENT TROU­BLE-FREE OPERATION.

THE INSTALLATION INSTRUCTIONS CONTAINED HEREIN ARE FOR THE USE OF
QUALIFIED INSTALLAION AND SERVICE PERSONNEL ONLY. INSTALLATION OR
SERVICE BY OTHER THAN QUALIFIED PERSONNEL MAY RESULT IN DAMAGE TO THE
BR/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

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, 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.

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.

3

INSTALLATION

INSTALLATION

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 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
unsatisfactory oven performance, check with the exhaust fan in the “OFF” position.

Clearances

Adequate clearances must be provided in the aisle and at the side and back to allow for servicea­bility. Adequate clearance for air openings into the combustion chamber must be provided.

CLEARANCES

COMBUSTIBLE NONCOMBUSTIBLE
CONSTRUCTION CONSTRUCTION

BACK: 2” 0”
LEFT & RIGHT SIDE: *6” 0”
WITH 4” OR 6” LEGS: SUITABLE FOR INSTALLATION ON COMBUSTIBLE FLOORS.
WITHOUT LEGS: FOR USE ONLY ON NONCOMBUSTIBLE FLOORS.

CAUTION!

DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATION AIR TO THE

RANGE(S). KEEP THE APPLIANCE AREA FREE AND CLEAR FROM COMBUSTIBLES.

ASSEMBLY:

Uncrate range as near to final location as possible. Remove all shipping wire from burners and all
packing material and accessories from unit. Then assemble as follow:

1. When legs are provided, 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.

2. If top castings are removed, identify castings to they are replaced in the same position and on
the same range as when received from the factory.

INSTALLATION

Setting in Place

Battery Arrangements

1. Place the first range in the exact position it will occupy in the battery.

2. Using a carpenter’s level, level the unit from front to rear and side to side. Adjust as follows:

4” ADJUSTABLE LEGS: Adjust by turning foot on adjustable legs.

WITHOUT LEGS: Place shim under the low side. This operation is important since

variations in floors and curbs are common. Unless units are level, difficulty will be encountered in

a aligning the gas supply manifold and the units will not butt together tightly.

3. Remove the upper valve panel from the range.

4. Move the next range into position.

5. Engage union nut on manifold with male fitting on next unit 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 the
battery are connected.

7. Tighten manifold 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.

C CHECK ENTIRE SYSTEM FOR GAS LEAKS.

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 plate is pitched to the front to provide for grease runoff. (See Fig. 1)

High Shelf, High Back or Stub Back:

Lift high shelf, high back or stub back above the range and slide legs into position. (See Fig. 2)

INSTALLATION

GAS APPLIANCE REGULATOR

Unless otherwise specified, the range is equipped with fixed orifices for use with a manifold pressure
of 4.0 or 6.0” water column for natural gas and 10.0” water column for propane gas. (Note: See rat­ing plate for manifold pressure.)

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

4. Unless the manifold pressure on all connected appliances is the same, a separate pressure reg-

TIME OF INSTALLATION.

ulator must be supplied for each appliance(s) having different manifold pressures.

INSTALLATION

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 recommended. 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.

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 the pilot flame. Adjust flem to a
point where only a trace of yellow tip remains.

HOT TOP & FRYTOP: Each pilot is controlled by a pilot valve. Turn adjusting screw until pilot
flame is 1/2” high.

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 THRE IS

A DANGER OF FIRE OR EXPLOSION DEPENDING UPON CONDITIONS. NEVER USE

IF LEAKAGE IS DETECETD.
