INSTALLATION
The Montague Technostar gas ranges are manufactured for use with the type of gas indicated on
the nameplate.
The Montague Technostar 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/CGA-B149.1,
OR THE PROPANE INSTALLATION CODE CAN/CGA-B149.2, AS APPLICABLE,
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).

INSTALLATION
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.
PROVISIONS MUST BE MADE FOR ADEQUATE AIR SUPPLY TO THE UNIT.
Ventilating Hood
The range(s) must be installed under a properly designed 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.

INSTALLATION
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.
DO NOT LIFT RANGE BY THE FRONT RAIL.
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
non-combustible material.
2. Install door handle by placing threaded ends of handle through
pre-punched holes on exterior door panel (see diagram for correct orientation).
Secure handle with screws that are mounted through pre- punched holes of in-
terior liner.
3. Lift high shelf above the range and slide channels into position. Secure
to range back with screws that are provide.

INSTALLATION
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 sections by aligning cut-outs of open top grate ( A )
with pattern of the burner head ( B ). Grate should have even spacing around
the body of the burner head ( C ).
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 & COUNTER INSTALLATION ON LEGS: The foot of the leg
should be adjusted all the way in before attempting to level the unit. To increase
the height of the leg, rotate the adjustable foot clockwise until desired height is
achieved. Repeat this procedure with all legs. Use a level to ensure that all legs
have been adjusted correctly.
CURB INSTALLATION: Level range from front to rear and side to side us-
ing a carpenter’s level. Place shim under low side.

INSTALLATION
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 and proper ventilation. The
heat from the plate should rise to the rear of the unit to
prevent damage to valves and other components. Be sure
wooden strips have been removed from below 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 should be 8 to 14 W.C.‖
FOR PROPANE GAS: This gas pressure regulator is factory adjusted for 10.0‖ W.C.
manifold pressure. The rated inlet pressure to the regulator should be 12 to 14‖ W.C.
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 LIQUIFIED 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 a minimum I.D. equal to 3/4‖ pipe must be used. Line sizing should be based
on the BTU rating or requirement of the unit installed. 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.
