is only adjustable for 4" and 10" gas pressure.
There is a blue plastic pin on the inside of the
cap, marked "NAT" and "LP". Pull this pin from the
cap and insert it the other way round. Snap the
pin into the cap. The pin must be positioned as in
the drawing above. The regulator is now
adjusted for propane gas 10" WC. (For natural
gas 4", turn the pin back.) Screw the cap back on
the regulator. The pressure regulator is equipped
with a separate connection for pressure testing
purposes. Check gas pressure. Permitted
pressures: min. 11" WC (5" WC, natural gas), max.
1/2 psi.
