Just unscrew the pressure gauge and screw in a new one with a little pipe dope on it. Just get it snug then rotate til it faces you. You probably need to pull your burner's nozzle assembly and clean/adjust and change the nozzle (don't touch the pinhole), without breaking the electrodes. Get a hold of a book such as Audel's Oil Burners. If you needed help with the guage, you'll be in way over your head. The oil will burn off. If you do spray a lot in, it might smoke pretty bad until the chimney starts pulling it, so ventilate. Make sure your filter is not plugged with emulsified water/oil. The differential is one number and the pressure setting one other. The boiler goes off at the HIGHER pressure and back on at the LOWER pressure until the stat is satisfied. If the differential is additive you add that amount to the LOWER to get the HIGHER. The controller should be set as low as possible, with a differential of 1 or so.
