You say it is housed in a outside compartment, did you check the back side of that compartment from under the moho for a round white hand hole that you screw out, the valves may be in there, a friend of mine moho is set up that way, a real bi*#& to get at.

Thanks all for your replies. Finally gave in and took back to dealer since I just bought it and he had a hard time finding. There is an access in the compartment of the water heater accessed thru the next compartment where the propane tank is. The access hole is at the front on the side however the valve is at the back on side with no access and you need skinny arms to reach it thru the access hole. I might just be cutting another access hole toward the back. Again thanks for your replies.
