Installation and Operation Manual
GAS SPECIFICATIONS
GAS INLET PRESSURE
For rotisseries running on natural gas, an inlet pressure of 17�5–25 mbar (7 to 10" W�C�) is recommended to ensure optimum
rotisserie performance� Incoming gas pressure below this range will affect rotisserie performance, the lower the pressure the greater
the negative impact� If the gas supply pressure is greater than 34 mbar (14" W�C� or 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 rotisseries running on LP, the recommended inlet pressure to ensure optimum rotisserie performance is 25–30 mbar (10 to 12"
W�C�) Incoming gas pressure below this range will affect rotisserie performance, the lower the pressure the greater the negative
impact� If the gas supply pressure is greater than 34 mbar (14" W�C� or 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 rotisserie� To ensure proper operation,
all gas piping and fittings leading up to the rotisserie should have an inside diameter equal to or greater than that of the rotisserie
gas connection� Also make sure that a readily accessible shut off valve (supplied by others) is installed near the rotisserie, 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�
Use a properly sized flexible pipe and quick disconnect device 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� Rotisserie 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 rotisserie warranty�
Countertop models may be hard-piped if necessary�
GAS CONNECTION
The gas control valves that operate the burners are located behind the rear service panels� SV-1 controls the Flame Post Burner�
The manifold pressure is checked at the outlet port on the SV-1 gas valve�
SV-2 and SV-3 control the left and right Infrared (IR) Burners� The manifold pressures are checked at the outlet port on the
individual gas valves�
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�
Wood Stone rotisseries are equipped with a 19mm (3/4") FBSPT gas connection (female thread)� 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 to check for leaks�
DO NOT USE A FLAME TO TEST FOR LEAKS!
All gas piping up to the rotisserie must have a minimum inside diameter of 19mm (3/4"), 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 rotisserie
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�
Natural Gas (NG): Maximum inlet gas pressure must not exceed 34 mbar (14" W.C. or 1/2 psi)
Propane (LP): Maximum inlet gas pressure to the rotisserie, after the external regulator (if used),
must not exceed 34 mbar (14" W.C. or 1/2 psi)
