INSTALLATION INSTALLATION

INSTALLATION

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

The MONTAGUE gas griddles are produced with the best possible materials and workman­ship. PROPER INSTALLATION IS ESSENTIAL FOR SAFE AND EFFICIENT TROUBLE­FREE 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 servic-

ing 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 GRIDDLE (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 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).

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

WARNING—ELECTRICAL GROUNDING INSTRUCTIONS

This appliance is equipped with a three-prong (grounding) plug for your protection

against shock hazard and should be plugged directly into a properly grounded three-

prong receptacle. Do not cut or remove the grounding prong from this plug.

INSTALLATION

THIS APPLIANCE WHEN INSTALLED MUST BE ELECRICALLY GROUNDED IN

ACCORDANCE WITH LOCAL CODES, OR IN THE ABSENCE OF LOCAL CODES, WITH

THE NATIONAL ELECTRICAL CODE, ANSI/NFPZ No. 70 OR THE CANADIAN ELECTRICAL

CODE, CSA C22.2.

VENTILATING HOOD

The griddle(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 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 clearance must be provided in the aisle and at the side and back 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 griddle as near to final location as possible. Remove all shipping straps, wrapping,
cardboard, or upper crating. Leave the bottom wood pallet. Use a fork lift or an equipment hoist to
raise the bottom pallet and the griddle off the floor. Loosen the two Allen screws in each leg socket
and tighten the Allen screws. Place the griddle on the counter or equipment stand where it will be
used. For models supplied with an equipment stand, raise the four legs and lower shelf assembly
into the leg sockets and tighten the Allen screws. Lower the griddle and stand into place where it will
be used. Remove and discard the wood pallet when completed.

WIRING DIAGRAM

The wiring diagram is located on the rear of the griddle. If it cannot be found, please call your
local Montague Servicer or Montague Dealer.

SETTING IN PLACE

Using an accurate carpenter’s level, level the griddle front to back and side to side using the
adjustable foot at the bottom of the legs. Turn the bottom of the foot counter-clockwise with a wrench
to lengthen the leg. If casters are added to an equipment stand, there is no adjustment to level the
griddle. If floors are uneven, shim plates may be required for proper operation of the griddle.

ADJUSTING THE GRIDDLE PLATE

For proper operation of the griddle and adequate grease runoff, it is imperative that the grid­dle plate be pitched toward the front. An improperly pitched plate may result in unwanted grease
build-up, excessive guard rail and control panel temperatures, pilot outages, and premature failure
of the griddle control components and burners.

Plate leveling bolts are located beneath the rear of the griddle plate. To access these bolts,
remove the back and top screws that hold the flue extension in place and lift the extension off. Place
an accurate carpenter’s level in the center of the plate. Turn the leveling bolts equally counter­clockwise with a wrench until the rear of the plate is raised sufficiently to “crack” the bubble (see
Figure below). This will result in approximately a 1/8 inch forward pitch of the plate. Replace and fas­ten the flue extension.

INSTALLATION

GAS APPLIANCE REGULATOR

The gas regulator supplied with the griddle must be installed on the manifold inlet at the
back of the unit and adjusted for the manifold pressure specified on the equipment nameplate.
Unless otherwise specified, a manifold pressure of 6.0 inches of water column for natural gas and

10.0 inches of water column for propane gas is appropriate.

GAS CONNECTION

Before connecting the griddle to the gas supply line, be sure that all new piping has been
cleaned and purged to prevent any foreign matter form 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 griddle and located in and
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 the
griddle 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 griddle.

TEST ALL PIPE JOINTS FOR LEAKS BEFORE OPERATING THIS, INCLUDING 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 OTHR JOINTS. DO NOT USE AN OPEN FLAME.

ABSOLUTELY NO LEAKAGE SHOULD OCCUR, OTHERWISE THERE IS A DANGER OF

FIRE OR EXPLOSION DEENDING UPON CONDITIONS. NEVER USE IF LEAKAGE IS

DETECTED.

INSTALLATION

PILOT ADJUSTMENT

Pilots on all griddles, except those with the suffix “-MFF” are controlled by fixed orifices
and are not adjustable. If the “-2,4OB” model option for open for open burners is included, then
these pilots are adjustable. The front and rear pilots are controlled by one valve. To adjust the
pilots, turn the adjusting screw counter-clockwise to increase or clockwise to decrease the pilot
flame. Adjust the flame to a point where only a trace of yellow tip remains.

Models with suffix “-MFF”, both griddle and open burner pilots are controlled by fixed
injectors and cannot be adjusted.

BURNER ADJUSTMENT

The efficiency of the griddle depends on a delicate balance between the supply of air and
volume of gas so that complete combustion is achieved. Whenever this balance is disturbed,
poor operating characteristics occur.

The air supply is controlled by an air shutter on the front of the burner. The air shutter
openings should be increased until the flame on the burner begins to “lift”. The air shutter should
then be closed slightly and locked in place. A yellow streaming flame indicated insufficient air.
This condition can be corrected by increasing the air shutter opening.

THERMOSTAT ADJUSTMENT

The griddle thermostats are calibrated as the factory and need no additional adjustment if
gas manifold pressure is correct. If transit or local conditions have affected the calibration, then
refer to the service section of this manual for proper procedures for recalibration.

FROM COMBUSTIBLES.

GAS CONTROLS

IN THE EVENT A GAS ODOR IS DETECTED, SHUT DOWN UNITS AT MAIN SHUT

OFF VALVE AND CONTACT THE LOCAL GAS COMPANY OR GAS SUPPLIER FOR

SERVICE.

MODELS WITH SUFFIX “-M & T”

These models contain standing automatic pilots without pilot safety valves. To light the
griddle pilots, first make certain all burner manual valves or thermostat dials are rotated full
clockwise to the “OFF” position. Open the gas supply shut-off valve. Immediately push the piezo
igniter button repeatedly until the pilot flame is visible through the pilot viewing slot in the upper
control panel. Repeat procedure for all pilots. If these models contain the “-(2,4)OB” open
burner option, follow the same procedure above, then light each pilot with a match or taper by
accessing through the top grate openings.

To operate the griddle or open burners with manual valves (model suffix “-M”) first
check that the pilot(s) are burning. Then rotate the burner valve handle counter-clockwise to full
“ON” to ignite the burner. Adjust the flame height to obtain the desired heat. To shut down,
rotate the valve handle clockwise to the “OFF” position.

To operate the griddle on models with modulating thermostat controls (model suffix “-
T”), first check that the pilot(s) are burning. Then push the thermostat dial inward and rotate dial

counter-clockwise fully to ignite the burner. After ignition, turn the thermostat dial to the desired
setting. To shut down, rotate the thermostat dial clockwise to the “OFF” position.

OPERATION

MODELS WITH SUFFIX “-SAT, SST, MST, & -TSF”

These models contain standing automatic pilots with 100% pilot safety valves that automatically
shut off the gas supply if the griddle pilot goes out. To light the griddle pilots, first make certain all
burner manual valves or thermostat dials are rotated fully clockwise to the “OFF” position. If the
model contains a main power switch it should be turned off. Loosen the two screws in the lower
control panel sufficiently to remove the upper control panel by lifting up and then outward. Open
the gas supply shut-off valve. Locate the red button on the pilot safety valve and hold the button
in. Repeatedly push the appropriate piezo igniter button until the pilot is visible through the
pilot-viewing slot. Continue to hold the button down for approximately 30 seconds or until the pilot
remains burning after the button is released. If the pilot goes out, repeat process. Continue
procedure until all pilots are burning. Replace the upper control panel and tighten the screws in
the lower panel. This procedure does not need to be repeated unless the pilot flame is extin­guished.

On models containing the “-(2,4)OB” open burner option, these pilots are lit from above by
accessing through the grate openings. First make certain the burner valves are rotated full
clockwise to the “OFF” position. Open the gas shut-off valve. Light the pilots for each burner with
a match or taper.

To operate the griddle/open burners with manual valves (model suffix “-MST”), first check that
the pilot(s) are burning. Then rotate the burner valve handle counter-clockwise to full “ON” to
ignite the burner. Adjust the flame height to obtain the desired heat. To shut down, rotate the
valve handle clockwise to the “OFF” position.

To operate the griddle on models with modulating thermostat controls (model suffix “-TSF”), first
check that the pilot(s) are burning. Then push the thermostat dial inward and rotate dial counter­clockwise fully to ignite the burner. After ignition, turn the thermostat dial to the desired setting. To
shut down, rotate the thermostat dial clockwise to the “OFF” position.

To operate a griddle with snap-action thermostats (model suffix “-SAT”), first check that the
pilots are burning and the main power switch is “ON” (red indicator light is on). Turn the desired
burner thermostat dial(s) clockwise to the set temperature. The amber burner indicator light next
to the dial will come on and remain on until the selected temperature is reached and the burner
turns off. During operation the burner indicator light will cycle on and off with the burner as the
thermostat maintains the set temperature. To turn off the burner, rotate the thermostat dial
counter-clockwise to “OFF”. To turn off the griddle, turn the main power switch to “OFF”.

To operate a griddle with solid-state thermostats (model suffix “-SST”), first check that the pilots
are burning and the main power switch is “ON”. Turn on the burner thermostat switch (press the
“I” marking) next to the thermostat dial. The amber burner indicator light will come on with the
burner. Set the dial to the desired set temperature. The burner indicator light will go out when the
set temperature is reached, and will cycle on and off during operation as the thermostat maintains
the set temperature. To turn off the burner, rotate the thermostat dial clockwise until it stops, AND
TURN OFF THE BURNER THERMOSTAT SWITCH (press the “O” marking). To turn off the
griddle, turn the main power switch to “OFF”.
