Mountain Home Oven Installation and Operation Manual

GAS INLET PRESSURES

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 opera-

tion and  performance of the oven.

Proper gas inlet pressures are as follows:

NATURAL GAS (NG) – 6.5" W.C. MIN TO 14" W.C. MAX

PROPANE (LP) – 10.5" W.C. MIN TO 14" W.C. MAX

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. This appliance requires no modifications or adjustments for use at high altitudes

Incoming gas pressure (NG or LP) must not exceed 1/2 psi (14" W.C.) if incoming gas pressure exceeds 1/2 psi, an 

external regulator, provided by others, must be installed.

The Wood Stone Gas appliances are equipped with a 3/4" FNPT gas connection located at the rear left of the 

appliance. 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 and SV-2 are the gas control valves that operate under floor infrared burner and the interior radiant burner, 

respectively. SV-1 is located directly behind the service/intake panel and in front of the under floor infrared burner. 

SV-2 is located under the appliance to the rear left.

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 manifold pressure test port for the radiant burner is a 1/8" NPT plugged tapping located at the base of the 

T-junction between the SV-2 valve and the radiant/interior burner.

The burner manifold pressure has been adjusted and tested at the factory. A variety of factors can influence this 

pressure, so it may be necessary to test the burner manifold pressure and adjust the valve as necessary to achieve 

the specified pressure. Note: The gas control valves are shipped in the ON position.

Specified burner manifold pressures shown on following page.
