Cascade Gas-Fired Rotisserie
Installation and Operation Manual
UTILITY SPECIFICATIONS
This oven requires no modifications or adjustments for use at high altitudes.
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.
SV-1 is the gas control valve that operates the upper Infrared (IR) Burner� The manifold pressure is checked at the outlet port on
the SV-1 gas valve�
SV-2 is the gas control valve that operates the lower Radiant Burner� The manifold pressure is checked at the outlet port on the
SV-2 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 CONNECTION
The Cascade Gas-Fired Rotisserie is equipped with a 1-inch FNPT gas connection (see the UTILITY CONNECTIONS section
for exact location)� Have a licensed gas installer provide the hook-up and test all fittings and pipe connections for leaks� Use
approved gas leak detectors (soap solutions 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 of the full flow type�
Wood Stone recommends that the rotisserie be equipped with a manual, individual shutoff valve, located between the oven and
the main gas supply, and that this shutoff valve (supplied by others) be left readily accessible� Wood Stone also recommends that
inspection and maintenance of the burners and gas piping connections of this appliance be performed at regularly scheduled
intervals and only by professional gas appliance service agencies�

GAS INLET PRESSURE
For ovens running on natural gas, an inlet pressure of 7 to 10" W�C� 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�
Maximum inlet gas pressure must not exceed 14" W.C. (1/2 psi)
