GAS SPECIFICATIONS
GAS INLET PRESSURE
For ovens running on natural gas, an inlet pressure of 7 to 10" WC is recommended to ensure optimum oven performance�
Incoming gas pressure below this range will affect oven performance, the lower the pressure the greater the negative impact� If
the gas supply pressure is greater than 14" W�C� (1/2 psi), an external regulator, supplied by others, is REQUIRED to lower the
gas pressure to the acceptable range� Issues caused by low or high gas pressure are installation issues, and will not be covered
under the Warranty�
For ovens running on LP, the recommended inlet pressure to ensure optimum oven performance is 10 to 12" W�C� Incoming gas
pressure below this range will affect oven performance, the lower the pressure the greater the negative impact� If the gas supply
pressure is greater than 14" W�C� (1/2 psi), an external regulator, supplied by others, is REQUIRED to lower the gas pressure
to the acceptable range� Issues caused by low or high gas pressure are installation issues, and will not be covered under the
Warranty�
For all installations, follow best practices for proper gas line pipe sizing for the line serving the oven� To insure proper operation,
all gas piping and fittings leading up to the oven should have an inside diameter equal to or greater than that of the oven
gas connection� Also make sure that a readily accessible shut off valve (supplied by others) is installed near the oven, and in
accordance with all applicable codes� Shut off valves must be of the full-flow type, and not introduce any restriction into the
gas line�
The connection to the oven should be hard-piped whenever feasible� If this is not possible, use a properly sized flexible connector
approved for this application� When using a flexible connector make sure that its design does not present any reduction in pipe
diameter or other restriction� Oven issues caused by improper pipe sizing, improper shut off valves, restrictive connectors, or any
other deficiency in the gas supply design or installation will not be covered under the oven warranty�
GAS CODE LIMITATIONS
The installation of this appliance must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code,
ANSI Z223�1 or The Natural Gas Installation Code CAN/CGA-B149�1 as applicable�
The appliance and its individual shutoff valve (supplied by others) must be disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in excess of 1/2 psi (14" W�C�) (3�45 kPa)�
The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve (supplied by others)
during any pressure testing of the gas supply piping system at test pressure, equal to or less than 1/2 psi (14" W�C�) (3�45 kPa)�
Maximum inlet gas pressure must not exceed 14" W.C. (1/2 psi)
