I removed the outside tank. The tank is in the left box of the refrigerator
now. I will check the tank pressure.

Did you say the altitude?

Okay, I will try this work. Thanks David..

The holes are top and under with burner.
The pic indicates both holes.

Okay.. I will shut this hole completely.

I went to Gas-station today. Then, I asked about the Japanese Gas standard.
He said to me.
The pressure level from the tank-hose.---->230~330mmH2O
Burner combustion levels.----------> 200mmH2O up
The component of Gas.-------------> 80%-up Propan, 20%-Butan

Are these different from US-LPG?

The gas pressure is possible with the regulater valve(Incl level meter).
However, I don't have it now. My gas-regulater always supplies the gas to
the refrigerator in the constant level.

I forwarded the mail of Puzerewski to list directly.
I apologized for that my act.
