3. Determine the type of regulator you have:
Style 1: The cap has a slot and “NAT” printed on it.
Remove access cap by using a flat-blade screwdriver or coin,
turning the access cap counterclockwise.
The gas pressure regulator has two settings that are stamped
on either side of the cap. Turn the cap and reinstall into
regulator with the stamp “LP” visible from the outside of the
regulator.
Style 2: The access cap has a slot in it or a hex shape,
without any printed text.
Remove the access cap by using a flat-blade screwdriver or
wrench turning the access cap counter clockwise.
If Seven Universe is printed on the regulator, unthread the
spring retainer by rotating it counter clockwise. If Maxitrol is
printed on the regulator then apply force to the flat side of the
spring retainer to remove it.
Turn over the spring retainer to place the disk on the spring
retainer far from the access cap.
Install the Seven Universe spring retainer by turning it
clockwise to thread it fully into the access cap, or for the
Maxitrol spring retainer by applying pressure to snap the
spring retainer into the access cap.
Reinstall the cap and seal onto the regulator by turning
clockwise.

4. Test the gas pressure regulator and gas supply line.
The regulator must be checked at a minimum 1" (2.5 cm)
water column above the set pressure. The inlet pressure to
the regulator should be as follows for operation and checking
the regulator setting:
Propane Gas:
Minimum pressure: 10" (25.4 cm) WCP
Supply pressure: 14" (35.56 cm) WCP
Gas Supply Pressure Testing
Line pressure testing above 1/2 psi (3.5 kPa) gauge 14"
(35.5 cm) WCP
The cooktop and its individual shut-off valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
1/2 psi (3.5 kPa).
Line pressure testing at 1/2 psi (3.5 kPa) gauge 14"
(35.5 cm) WCP or lower
The cooktop must be isolated from the gas supply piping
system by closing its individual manual shut-off valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psi (3.5 kPa).
