GAS CONNECTION
SV-1 is the gas control valve that operates the Underfloor Infrared (IR) burner and SV-2 and SV-3 are the gas control valves that
operate the interior radiant burner(s)
. NOTE: Some models are only equipped with two valves.
Wood Stone recommends that the Fire Deck be equipped with a manual, individual shut-off valve, located between the oven and
the main gas supply, and that this shut-off 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 17�5 to 25 mbar (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 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 ovens running on LP, the recommended inlet pressure to ensure optimum oven performance is 25 to 30 mbar (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 34 mbar (14" W�C� or 1/2 psi), the supplied external regulator 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�
The Wood Stone WS-FD-6045-CE and WS-FD-8645-CE are equipped with a 19 mm (3/4") FBSPT female thread gas connection�
Have a licensed gas installer provide the hookup 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 FLAME TO TEST
FOR LEAKS!
All gas piping up to the oven 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�
SV-1 is the gas control valve that operates the Underfloor Infrared (IR) Burner� The manifold pressure is checked at the outlet port on
the SV-1 gas valve� SV-2 (and SV-3 / SV-4 if equipped) are the gas control valve(s) that operate the interior Radiant Burner(s)� The
manifold pressure is 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�
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 oven, after the external regulator (if used),
must not exceed 34 mbar (14" W.C. or 1/2 psi)
