No, I tried this first but the burner hole is not a pressurized
location. If you plug the hole with your finger and turn on the burner,
gas can still be heard and smelled. You must remove one of the copper
lines from the "y" fitting at the tank regulator and push it to one side
out of the way. The lower one is easiest to get to. Use a wrench on the
square sides of the "y" to hold it while you use a wrench on the copper
tubing nut. I then pushed a clear hose shaped in a "u" that already had
some water in it, over the nipple. My friend held the hose while I
turned on the gas and measured it with a tape measure. One column goes
lower and the other will rise. Measure the distance in height between
them. I had previously removed the bottom shield from the tank. It is
held on by two 13 mm bolts and nuts. Be careful not to let the water
flow all the way to the propane tank. I don't have time right now to do
a complete detailed write up of this procedure but maybe tonight I will.
On the body of the Marshall pressure regulator is a white plastic screw
in plug. Remove this plug to get at the adjustment screw. A Phillips
screwdriver is needed to turn the adjusting screw. DO NOT MAKE ANY
ADJUSTMENT UNLESS YOU HAVE THE "GAUGE" CONNECTED AND WORKING. I found
that on my Marshall 260 that one FULL turn clockwise increased the
pressure by 1 inch. I set mine to 10 inches. CHECK FOR LEAKS WITH SOAPY
WATER AFTER RECONNECTING THE COPPER GAS LINE.
