Southbend In&a-Red Broilers are unique in design. They incorporate our exclusive Schwank ceramic tile burners,
which generate i&a-red rays that provide better quality products in about one-half the usual broiling time,
with less gas input than ordinary broilers. Very little energy is wasted in heating secondary surfaces, as is
necessary in conventional-type broilers.
Since the surface of these tiles become red hot in less than one-half minute, the unit is ready to start broiling
with a very short preheat time, thereby saving
These glowing surfaces emit intense infrared rays, which are transmitted directly onto the product, thereby
yielding better tasting broiled food in less time.
Use of 100% clean primary air, which is constantly conveyed to these burners, insures efficient combustion and
maintains full production capacity and maximum recovery, even in the most severe conditions of
and smoke atmospheres, which
The Southbend I&a-Red Broilers provide such speed and recovery that broiling techniques may require some
modification in order to take full advantage of its productive capabilities.

THESE PROCEDURES MUST BE FOLLOWED BY QUALIFIED PERSONNEL OR
WARRANTY WILL BE VOIDED.
GENERAL:
THE UNIT, WHEN INSTALLED, MUST CONFORM WITH LOCAL CODES, OR IN THE ABSENCE
OF LOCAL CODES, WITH THE NATIONAL FUEL GAS CODE ANSI Z223.1-LATEST EDITION.
CANADIAN INSTALLATION MUST COMPLY WITH CAN/CGA-B149.1 NATURAL GAS INSTALLATION CODE, CODE CAN/CGA-B149.2 PROPANE INSTALLATION CODE.
These models are design certifed for operation on Natural and Propane gases.
The Serial Plate is located under the broiler grease drawer at the front, towards the left.

Minimum clearances from combustible construction:
NOTE: For Model Nos. MRA-32C and MRA-32W a 6” clearance should be provided at the right
side, since it is necessary on all models to remove the body side to gain access to the regulator and
118 NPT pressure test tap.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of
gas required for satisfactory performance. A pressure regulator, which is provided with each unit,
is set to maintain a 4” W.C. manifold pressure for natural gas and a 10” W.C. manifold pressure for
propane gas. However, to maintain these conditions the pressure on the supply line, when all units
are operating simultaneously, should not drop below 7” W.C. for natural gas or 11” W.C. for propane gas.
All pipe joints should be tested for leaks with a soap and water solution before operating the unit.
The test pressure should not exceed 14 ’ W .C.

AT TEST PRESSURES EQUAL TO OR LESS THAN 112 PSIG (3.45 kPa)
(13.84 IN. W. C./.
The unit must be installed in such a manner that the flow of combustion and ventilation air are not
OBSTRUCTED. An adequate air supply for combustion is obtained at the right rear of the unit. These
openings must NOT be OBSTRUCTED in any way while the unit is operating. The top and right
side must be accessible for service.
EXHAUST FANS AND CANOPIES:
Be sure to inspect and clean ventilation system according to the ventilation equipment manufacturers
instructions. Canopies are set over ranges, ovens, etc., for ventilation purposes. It is recommended
that a canopy extend 6” past appliance and be located 6’ 6” from the floor. Filters should be installed
at an angle of 45 degrees or more with the horizontal. This prevents dripping of grease and facilitates collecting the run-off grease in a drip pan, usually installed with a filter. A strong exhaust fan
tends to create a vacuum in the room and may interfere with burner performance or may extinguish
pilot flames. Fresh air openings, approximately equal to the fan area, will relieve such vacuum. In
case of unsatisfactory performance on any appliance, check with the exhaust fan in the “OFF” position.

WARNING:
FOR AN APPLIANCE EQUIPPED WITH CASTERS, THE INSTALLATION SHALL
BE MADE WITH A CONNECTOR THAT COMPLIES WITH THE STANDARD FOR
CONNECTORS FOR MOVABLE GAS APPLIANCES, ANSI Z21.69ANSI 221.691987,
AND ADDENDA, Z21.69a-1963, AND A QUICK-DISCONNECT DEVICE THAT COMPLIES WITH THE STANDARD FOR QUICK-DISCONNECT DEVICES FOR USE
WITH GAS FUEL, ANSI 221.41-1978, AND ADDENDA, Z21.41a-1981 AND
Z21.41b-1983. ADEQUATE MEANS MUST BE PROVIDED TO LIMIT THE MOVEMENT OF THE APPLIANCE WITHOUT DEPENDING ON THE CONNECTOR AND
THE QUICK-DISCONNECT DEVICE OR ITS ASSOCIATED PIPING TO LIMIT THE
APPLIANCE MOVEMENT.
,
IF DISCONNECTION OF THIS RESTRAINT IS NECESSARY TO REMOVE THE
APPLIANCE FOR CLEANING, ETC., RECONNECT IT WHEN THE APPLIANCE
IS MOVED TO ITS ORIGINALLY INSTALLED POSITION.
GAS CONNECTION:
1. All MRA- Series broilers are factory equipped with a pressure regulator which is set for the type
of gas denoted on the serial plate.
2. If applicable, the vent line from the gas appliance pressure regulator shall be installed to the
outdoors in accordance with local codes or, in the absence of local codes, with the National Fuel
Gas Code, ANSI Z223.1-Latest Edition.
3. Gas supply connection is made on the right side. Remove the right body side for complete
accessibility to connection.
4. Gas supply connection can be made:
a. Rear:
Connection can be made by going directly into the pressure regulator (female connection
3/S NET).
b. Top:
Connection can be made by:
1. Removing knockout hole in top partition.
2. Screwing elbow into inlet end of regulator.
3. Cut access hole through expanded metal top.
4. Screwing supply pipe into elbow.
c. Bottom:
Connection can be made by:
1. Removing knockout hole in bottom.
2. Removing knockout hole in bottom cover (not supplied in counter units).
3. Screwing elbow into inlet end of pressure regulator.
4. Screwing supply pipe into elbow.
CAUTION:
BE SURE TO HOLD PRESSURE REGULATOR WITH A WRENCH WHEN
TIGHTENING SUPPLY PIPE TO AVOID DAMAGE TO REGULATOR,
VALVE,
AND OTHER COMPONENTS.
5. The unit should be connected only to the type of gas for which it is equipped. Check type of gas
on rating plate. On all threaded connections, the pipe compound must be approved for use with
natural and propane gas.
6. Make sure burner valve is in the “OFF” position before connecting gas to unit. Test pipe connections thoroughly for gas leaks. Use soapy water only.
7. Turn on burners and bleed supply line, then turn burners off.
8. Light pilots and adjust so that flame comes out the ends of the pilot flame carriers and extends
to the burner tile surface. PILOTS ARE ADJUSTABLE THROUGH THE HOLE ABOVE THE
VALVE KNOB.
NOTE: The six burner shipping screws located at each end of the three burners must be removed
after installation.
