Mountain Series Installation and Operation Manual
GaS inLet preSSureS
The Wood Stone Gas appliances are equipped with a 3/4" NpT gas connection. 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 FLAME TO TEST FOR LEAKS!
SV-1 is the gas control valve that operates the underfloor infrared burner. SV-1 is located directly behind the service/
intake panel and in front of the under floor infrared burner.
The manifold pressure test port for the infrared under floor burner is a 1/8" NpT plugged tapping located near the left
end of the burner manifold.
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 INLET PRESSURES
Inlet pressure must be within the above ranges when the oven is running, and when the oven is off. No external regulator
is required when inlet pressures are within the ranges above. If inlet pressure exceeds 14” W.C. (1/2 psi), an external
regulator, by others, is required to prevent damage to the oven. If inlet pressure is below the minimum pressures shown
above, adjustment or modifications to the supply system will need to be made by the pipe installer and or the gas
supplier.
Proper gas inlet pressures are as follows:
Natural Gas –
6.5” W.C. min to 14” W.C. max
Propane (LP) –
10.5” W.C. min to 14” W.C. max
It is the responsibility of the installer to verify proper gas inlet (supply) pressure to the oven. problems caused by
improper gas inlet pressure are not covered by the oven warranty. proper gas inlet pressure is critical to the operation and
performance of the oven.
