INSTALLATION

The Montague gas broilers are produced with
the best possible materials and workmanship.

Proper installation is essential for safe and
efficient trouble-free operation.

NOTE: 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 broiler 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:

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, 1988,
Sec. 1.4.

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:
Reference: National Electric Code,
N.F.P.A. No. 70, 1988.

Read carefully and follow these
instructions.

The oven 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—1988, including:

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).

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 broiler 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 unsatisfactory oven
performance, re-check performance with the
exhaust fan turned “OFF.”

CLEARANCES

Adequate clearances must be provided in the
aisle in front of the broiler for safe operation,
removal of racks, drip tray and grease
container, and for serviceability. Adequate

clearance for air openings into the combustion
chamber must also be provided.

AREA FREE AND CLEAR FROM
COMBUSTIBLES.

SETTING IN PLACE

1. Uncrate unit and put into place. For easier
and lighter handling of the broiler, remove
coals, cast iron top grids, grid frame, drip
tray, grease container, and debris screen.

leveled by adjusting the legs.

BATTERY ARRANGEMENTS

1. Place the first unit 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:

FLOOR INSTALLATION ON LEGS

Adjust by turning foot on adjustable legs.

CURB INSTALLATION

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

3. Remove the valve panel from unit.

4. Move the next unit into position.

2. Wire ties securing burners are for shipping
purposes only and must be removed when
installing the appliance. This will permit the
burners to be readily removed during
future servicing. Remove all other packing
material from burner box.

3. For floor models, a set of 6” legs is packed
in the top section of the broiler (unless unit
is specifically ordered without legs). A
threaded receptacle is located on each
corner (and in the middle of units larger

than 36”) of the base of the unit. Each leg

has a similar mating thread. Use lift with
proper weight capacity to suspend unit in
order to allow legs to be screwed into the
threaded receptacles. Level unit by
adjusting legs. An unleveled unit will
adversely affect performance.

4. Counter units must be installed on a level
table or stand, and modular units must be

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. Check
entire system for gas leaks.

GAS HOOK UP

An adequate gas supply is imperative.
Undersized or low pressure lines will restrict

INSTALLATION

the flow of gas required for satisfactory
performance. A steady supply pressure

between 7” and 8” WC for natural gas and 11”
and 12” WC for propane gas is required. With

all units operating simultaneously, the
manifold pressure on all units should not show
any appreciable drop. Fluctuation of more
than 25% on natural gas and 10% on propane
gas will create pilot problems and affect
burner operating characteristics. Contact your
gas company for correct supply line sizes.

The unit should be connected only to the type
of gas for which it is equipped. Check type of
gas on rating plate.

1. 1-1/4” Front Manifold

The gas manifold of this appliance or of the
battery which it is a part must be connected to
a gas appliance pressure regulator adjusted
for the manifold pressure marked on the rating
plate.

IMPORTANT

For Propane Gas

The gas pressure regulator is factory adjusted

for 10.0” WC manifold pressure. The

maximum inlet pressure to the regulator
should not exceed the manufacturer
specification of 1/2 psi or damage to the
regulator may occur.

2. Manifold pressure must be maintained at
the pressure marked on the rating plate.
Improper pressure can result in faulty or
unsafe operation and/or premature
component failure.

3. Use a pipe joint compound which is
suitable for use with propane gas on all
threaded connections.

4. Turn off all burner valves.

5. Turn on gas supply and check all unions
for leaks. Use soapy water only for testing
on all gases. Never use an open flame to
check gas leaks.

THIS UNIT IS EQUIPPED WITH FIXED
ORIFICES FOR THE TYPE OF GAS
MARKED ON THE RATING PLATE. THE
ORIFICES ARE SIZED FOR THE
FOLLOWING MANIFOLD PRESSURE:

NATURAL: 6.0” WC

PROPANE GAS: 10.0” WC

1” Rear Manifold (Standard)

The gas pressure regulator supplied with this
unit must be used.

For Natural Gas

The gas pressure regulator is factory adjusted

for 6.0” WC manifold pressure. The maximum

inlet pressure to the regulator should not
exceed the manufacturer specification of 1/2
psi or damage to the regulator may occur.

IMPORTANT

IF PRESSURE TESTING PLEASE DO NOT
EXCEED FACTORY SPECIFICATION OF 1/2
PSI OR DAMAGE TO REGULATOR MAY
OCCUR.

FINAL ASSEMBLY

1. Reassemble the broiler by inserting the
bottom grates (that will be used to hold the
char-rock coals) with the flat surface facing
down and properly positioned in their
supports so they do not touch the burners.
Spread the coals randomly over the grates
to a maximum depth of 1-1/2”. Rearrange
the coals to eliminate void areas and large
openings. The proper amount of char-rock
coals are as follows:

24C: 7 lb., 30C: 10 lb., 36C: 12 lb., 48C: 14
lb., 60C: 20 lb., 72C: 24 lb.
