Test the Fischer regulator, "after" installation.
The proper way to set the regulator pressure is to have the manometer hooked up to a stove burner.
Run the furnace if possible, and the water heater at the same time.
The correct pressure is 11 to 13 inches of water column pressure.
Setting it to 12.5 inches, is preferred, especially if you will be in the mountains at all.
Setting a regulator with a small flow of LPG, can be very mis-leading.
I have seen regulaors that with, as an example, one burner going on the stove, seemed fine.
Fired up the furnace and the pressure went to zero.
ever take a regulator apart. If it cannot be adjusted properly, throw it away.
Repair parts do not exist for any LPG regulator.
