SECTION 2
INSTALLATION
Certain safety code requirements exist for the installation
of gas ovens; refer to the beginning of Section 2 for a list of
the installation standards. In addition, because the oven is
equipped with casters, the gas line connection shall be
made with a connector that complies with the Standard for
Connectors for Movable Gas Appliances, ANSI Z21.69 (in
U.S.A.), or, if applicable, Connectors for Movable Gas
Appliances, CAN/CGA-6.16 (in Canada), as well as a
quick-disconnect device that complies with the Standard
for Quick-Disconnect Devices for Use With Gas Fuel,
ANSI Z21.41 (in U.S.A.), or, if applicable, Quick-Discon-
nect Devices for Use With Gas Fuel, CAN1-6.9 (in Canada).
B. GAS CONVERSION
It is possible to convert ovens from natural to propane gas,
or from propane to natural gas, by changing the main and
pilot orifices.
WARNING: All installations, conversions and service work
must be performed by an authorized service agent.
NOTE: In Canada, to conform with the CAN/CGA-B149.2
propane installation code, the oven must be ordered
propane. It may not be converted in the field.
