INSTALLATION MANUAL
Installation must conform with local codes, or in the absence of local codes, with the National
Fuel Gas Code, ANSI Z223.1, Natural Gas Installation Codes, CAN/CGA-B149.1, or the Propane
Installation Code, CAN/CGA-B149.2, as applicable.
1.
The appliance and its individual shuto valve must be disconnected from the gas supply
piping system at test pressures in excess of ½ psig (3.45kPa).
2.
The appliance must be isolated from the gas supply piping system by closing its individual
manual shut-o valve during any pressure testing of the supply system at test pressures
in excess of ½ psig (3.45kPa).
SERVICE ACCESS
All service can be done through the Control Door opening and the Burner Door opening. An
access panel is located on the left side of the oven for more access to the controls. If this is
blocked o all service can be done from the front of the oven.
1
ELECTRICAL CONNECTION
A 15 AMP service must be provided for each oven. For 115 Volt usage, a cord and plug is
provided but connection to the electrical service must comply with local codes; or in the
absence of local codes, with the National Electrical Code, ANSI/NFPA No. 70 (or latest edition)
GAS CONNECTION
A ¾” NPT inlet is located at the rear of the oven. Undersized gas supply lines will restrict gas
supply and aect oven performance. If other appliances are supplied by the same supply
line the supply line must be sized to carry the combined volume without causing more than
½” pressure drop at the manifold of each appliance on the line at full rate. When installing a
stacked oven with one line, the line should be 1” to the tee and the 3/4” into each oven
NOTE: During installation, there will be air in the line. The air must be bled o before ignition
can be established.
GAS PIPING
A properly sized gas supply system is essential for maximum oven performance. Piping should
be sized to provide a supply of gas sucient to meet the maximum demand of all appliances
on the line without loss of pressure at the equipment.
Additional Gas Connection Instructions
GAS HOSE RESTRAINT
If the oven is mounted on casters, a commercial exible connector with a minimum of 3/4” (1.9
cm) inside diamter must be used along with a quick connect device.
The restraint, supplied with the Flexible Hose Kit, must be used to limit the movement of the
unit so that no strain is placed upon the exible connector. With the restraint fully stretched
the connector should be easy to install and quick connect.
1.
Mount the supplied bracket to the hold located on the rear or base frame on the same
side as the gas supply.
The connector must comply with the Standard Connectors for Movable Gas Appliances, ANSI
Z21.59 or Connectors For Moveable Gas Appliances CAN/CHA-6.16 and a quick disconnect
device that complies with the Standard for Quick Disconnect Devices for Use With Gas Fuel,
ANSI Z.41 or Quick Disconnect For Use With Gas Fuel CAN 1-6.9. Adequate means must be
provided to limit the movement of the appliance without depending on the connection and
the quick disconnect device or its associated piping. Adequate means must be provided to
limit the movement of the appliance qithout depending on the connection and the quick
disconnect device or its associated piping.

DELIVERY
Marsal & Sons, Inc. cannot assume responsibility for loss or damage suered in transit. The
carrier assumed full responsibility for delivery in good order when the shipment was accepted.
We are, however, prepared to assist you if ling a claim is necessary.
OVEN LOCATION
The oven should be installed in a location in which the facilities for ventilation permit satisfactor y
combustion of gas and proper venting. The oven should be located so as not to interfere with
proper circulation of air within the conned space. In buildings where normal inltration does
not provide the necessary air, outside air should be introduced.
It is essential that an adequate air supply to the oven be maintained to provide a sucient
ow of combustion and ventilation air.
•
Place the oven in an area that is free of drafts.
•
Do not place the oven on a curb base or seal to a wall. This will restrict the ow of air and
3
prevent proper ventilation. Pilot outages or yellow, oating ames on the main burners
are indicative of a lack of secondary air.
Before making any utility connections to this oven, check the rating plate to be sure the oven
specications are compatible with the gas and electrical services supplied for the oven. The
rating plate is located on the inside of the control door.
ADJUSTMENTS ASSOCIATED WITH INITIAL INSTALLATION
Each oven, and its component parts, have been thoroughly tested and inspected prior to
shipment. However, it is often necessary to further test or adjust the oven as part of a normal
and proper installation. These adjustments are the responsibility of the installer, or dealer.
Since these adjustements are not considered defects in material or workmanship, they are not
convered by the Original Equipment Warranty. They include, but are not limited to:
•
calibration of the thermostat
•
adjustment of the doors
•
burner adjustments
•
leveling
•
testing of gas pressure
•
tightening of fasteners
No installation should be considered complete without proper inspection, and if necessary,
adjustment by qualied installation or service personnel.
