INSTALLATION
GAS SUPPLY & INSTALLATION
The minimum size requirement for gas piping or a
flexible connector is 3/4 - inch (19mm). For long runs
of gas piping, the pipe diameter must conform to the
tables in the National Fuel Gas Code, ANSI/NFPA
Z223.1.
A listed gas shut-off valve must be installed
upstream of the appliance to shut off the gas
supply during servicing. The shut-off valve should
be accessible with the appliance in the normal
installation position.
If the oven or the oven stand is supplied with
casters, gas connection must be made with a flexible
connector that complies with the Standard for
Connectors for Movable Gas Appliances, ANSI
Z21.69; or in Canada, Connectors for Movable Gas
Appliances, CAN/CGA-6.16-M87. When using a
flexible connector, a quick disconnect device must
be used to comply with the Standard for Quick-
Disconnect Devices for Gas Fuels, ANSI Z21.41; or in
Canada, Quick Disconnect Devices for Use with Gas
Fuels, CAN1-6.9.
When a quick disconnect device and flexible
connector are used, a restraining device must be
installed to limit the movement of the appliance and
prevent damage to the connector or quick disconnect.
An example of a restraining device would consist
of a 2000 pound test, stainless steel cable, attached
to a structural member of the kitchen wall behind
the oven. The means of attachment should consist
of a quick connect snap so that the oven can be
disconnected when the appliance must be moved
away from the wall.
The other end of the cable should be permanently
attached to the rear frame of the oven. The cable
should be of sufficient length so that no strain is ever
placed on the flexible gas connector in the event of
accidental movement of the oven without properly
disconnecting the gas connector. The flexible
connector should be routed to form a downward
“U” loop between the building gas supply and the
permanent attachment at the rear of the oven.
The routing of the flexible connector must not be
made under the oven. Oven temperatures achieved
during operation are too hot for safe operation. Gas
piping should be installed from the point of gas
connection at the bottom, front of the oven to the
back of the oven where the flexible connector may be
safely used. See the illustration for the recommended
placement.

GAS PIPING MUST NEVER
BE INSTALLED TO RUN
UNDER THE BURNER
