6. Verify the DWYER # 1212 manometer reads 5-1/2" above the “0” mark, and 5-1/2" below
the “0” mark. This equals 11" water column of pressure. Adjust the Maxitrol regulator in a
clockwise direction to increase pressure, and in a counterclockwise direction to decrease
pressure.
Do not bottom out the regulator adjust screw. If you cannot get a reading, retest the inlet pressure to the
Maxitrol gas package.
