GAS SUPPLY & INSTALLATION REQUIREMENTS
®
COMBITHERM
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 qu ick conne ct sn ap so that
th e ove n 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.
