To Convert Gas Pressure Regulator
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 that 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 “NAT” or “LP” 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.
4. If the burner grates are installed, remove them.
Use the following charts to match the correct gas orifice
