3.
Determine the type of regulator you have:
Style 1:
The cap has a slot and “LP” printed on it.
Remove access cap by using a flat-blade screwdriver
or coin, turning the access cap counterclockwise.
The gas pressure regulator has 2 settings which are
stamped on either side of the cap. Turn the cap and
reinstall into regulator with the stamp “NAT” visible
from the outside of the regulator.
Style 2:
The cap does not have a slot and requires
a wrench to be removed.
Remove the access cap by using a wrench, turning
the access cap counterclockwise.
Remove spring retainer from the cap by pushing against
the flat side of the spring retainer. Look at the spring
retainer to locate the “LP” or “NAT” position. Turn over
the spring retainer so the “NAT” is showing on the bottom.
Snap the spring retainer back into the cap. Reinstall the
cap onto the regulator.
