FD-9690, 11275, 11290 and CS-90-112Installation and Operation ManualM0041.09 OCTOBER 2017PG 19 OF 32GAS SPECIFICATIONSGAS INLET PRESSUREFor ovens running on natural gas, an inlet pressure of 7 to 10" W�C� is recommended to ensure optimum oven performance� Incominggas pressure below this range will affect oven performance, the lower the pressure the greater the negative impact� If the gas supplypressure is greater than 14" W�C� (1/2 psi), an external regulator, supplied by others, is REQUIRED to lower the gas pressure to theacceptable 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 gaspressure below this range will affect oven performance, the lower the pressure the greater the negative impact� If the gas supplypressure is greater than 14" W�C� (1/2 psi), an external regulator, supplied by others, is REQUIRED to lower the gas pressure to theacceptable 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, allgas 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 allapplicable 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 connectorapproved for this application� When using a flexible connector make sure that its design does not present any reduction in pipediameter or other restriction� Oven issues caused by improper pipe sizing, improper shut off valves, restrictive connectors, or any otherdeficiency in the gas supply design or installation will not be covered under the oven warranty�GAS CODE LIMITATIONSThe installation of this appliance must conform with local codes, or in the absence of local codes, with the NationalFuel 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 anypressure 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)This oven requires no modifications or adjustments for use at high altitudes.SV-1 is the gas control valve that operates the Underfloor IR Burner� The manifold pressure is checked at the outlet port on the theindividual gas valve�SV-2 (and SV-3 / SV-4, etc�, if equipped) are the gas control valve(s) that operate the interior Radiant Burner(s)� The manifold pressureis checked at the outlet port on the the individual gas valve�The burner manifold pressures have been adjusted and tested at the factory� A variety of factors can influence these pressures,so be sure to test the individual burner manifold pressures and adjust the valves as necessary to achieve the required pressures�NOTE: The gas valves are shipped in the ON position�GAS CONNECTIONThe FD-9690, FD-11275, FD-11290, Fire Deck CS-90-112 and CS-96-90 are equipped with a 1-inch FNPT gas connection� Have alicensed gas installer provide the hook-up and test all fittings and pipe connections for leaks� Use approved gas leak detectors (soapsolutions or equivalent) over and around the fittings and pipe connections� DO NOT USE A FLAME to test for leaks!All gas piping up to the oven must have a minimum inside diameter of 1", including all fittings and shut off valves, which should be ofthe full flow type�Wood Stone recommends that the Fire Deck be equipped with a manual, individual shutoff valve, located between the oven andthe main gas supply, and that this shutoff valve (supplied by others) be left readily accessible� Wood Stone also recommends thatinspection and maintenance of the burners and gas piping connections of this appliance be performed at regularly scheduled intervalsand only by professional gas appliance service agencies�
