INSTALLATION

The Montague Grizzly gas oven ranges are manufactured for use with the type of gas indicated on the nameplate.
The Montague Grizzly gas convection oven type 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, NFPA No. 70.

READ CAREFULLY AND FOLLOW THESE INSTRUCTIONS

THE RANGE(S) MUST BE INSTALLED IN ACCORDANCE WITH LOCAL CODES, OR IN THE ABSENCE OF LOCAL
CODES, WITH THE NATIONAL FUEL GAS CODE, ANSI Z223.1, NATURAL GAS INSTALLATION CODE, CAN/CGA­B149.1, OR THE PROPANE INSTALLATION CODE, CAN/CGA-B149.2, AS APPLICABLE, INCLUDING:

1. The appliance and its indivi dual 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).

INSTALLATION

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 unsatisfactory 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.

Back:
Left & Right Side:

6" (15.2cm) HIGH LEGS: SUITABLE FOR INSTALLATION ON COMBUSTIBLE FLOORS.

WITHOUT LEGS: FOR USE ONLY ON NONCOMBUSTIBLE FLOORS.

DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATION AIR. KEEP THE

APPLIANCE AREA FREE AND CLEAR FROM COMBUSTIBLES.

INSTALLATION

ASSEMBLY

DO NOT LIFT RANGE BY THE FRONT RAIL.

Uncrate range as near to final location as possible. Remove all
shipping wire from burners and all packing material and accessories from
oven interior.

IF RANGE IS EQUIPPED WITH A FRYTOP SECTION, REMOVE WOOD SHIPPING STRIPS

LOCATED BELOW THE GREASE TROUGH.

Then assemble as follows:

Floor Mounted Range:

1. Screw the adjustable feet of the legs in all the way. Then
tightly screw the complete leg assembly into 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. See
diagram for correct orientation.

3. Lift high shelf above the range and slide channels
into position. Secure to range back with screws
that are provided.

3

INSTALLATION

Cabinet or Skeleton Ranges:

Follow above instructions.

Modular Ranges:

Assemble modular base and set in place. Adjust feet as
explained above.

Counter Ranges:

Set unit in desired position and secure to counter using holes
provided at rear and bracket at front.

All Ranges:

1. Install Open Top and Hot Top sections as shown in diagram
below. Install burner bowls and grates on Open Top section.

2. Install top burner valve handles and thermostat knob(s). If
top burner valve handles fit loose on valve shaft, spread
slot on end of shaft slightly with screwdriver blade so that
handle will fit snug.

3. When range is in permanent position, level unit by placing
carpenter's level on oven bottom and level from front to back
and side to side.

Adjust as follows:

FLOOR INSTALLATION ON LEGS: Adjust by turning the foot of the
adjustable leg. Make sure the leg does not turn.

COUNTER OR CURB INSTALLATION: Level range from front to rear
and side to side using a carpenter's level. Place shim under
low side.

4

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

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 1/2 psig (3.45kPa).

INSTALLATION

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.

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.

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 regulator 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.
