INSTALLATION

The range is manufactured for use with the type of gas indicated on the name plate.

The MONTAGUE Heavy Duty Chinese Range is 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 INSTALLATION AND SERVICE PERSONNEL ONLY. INSTALLATION OR

SERVICE BY OTHER THAN QUALIFIED PERSONNEL MAY RESULT IN DAMAGE TO

THE OVEN/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, 1984, 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, N.F.P.A. No. 70
– 1984.

READ CAREFULLY AND FOLLOW THESE INSTRUCTIONS

THE RANGE MUST BE INSTALLED IN ACCORDANCE WITH LOCAL CODES, OR IN
THE ABSENCE OF LOCAL CODES, WITH THE NATIONAL FUEL GAS CODE, ANSI
Z223.1-1984, 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

INSTALLATION

PROVISIONS MUST BE MADE FOR ADEQUATE AIR SUPPLY TO THE UNIT.

VENTILATING HOOD

The range 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. 96-1980, 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

FOR USE IN NONCOMBUSTIBLE LOCATIONS ONLY.

MINIMUM CLEARANCE FROM NONCOMBUSTIBLE CONSTRUCTION IS 0” FROM SIDE

AND 0” FROM BACK.

Adequate clearance must be provided in the aisle in front of the range for safe removal of drip
trays (if provided), and for serviceability. Adequate clearance for air openings into the combustion
chamber must be provided.

CAUTION!
DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATION AIR TO THE
RANGE. KEEP THE APPLIANCE AREA FREE AND CLEAR FROM COMBUSTIBLES.

secure legs to the body.

STANDARD SHELF OR PIPE SHELF:

2. Lift shelf above the range and position shelf flange over splash.

3. Align holes and bolt shelf into position using bolts removed in step 1.
