Adaptation of the pressure regulator for use with different type of gas
The pressure regulator supplied with the appliance is a convertible type pressure regulator for use with
Natural Gas at a nominal outlet pressure of 4” w.c. or LP gas at a nominal outlet pressure of 11” w.c. and it is
pre-arranged from the factory to operate with one of these gas/pressure as indicated in the pre-arranging
labels affixed on the appliance, package and Instruction booklet.
To convert the regulator for use with the other gas different from which one it is pre-arranged it is enough
perform the following operations:
1) Unscrew by hand the upper metal stopper of the regulator (Fig. 5).
2) Unscrew by hand the white plastic piece screwed under the above mentioned metal stopper, afterward
screw it again in opposite way under the metal stopper (for gas reference see the written “LP” and “NAT” with
relative indicating arrows on the white piece).
3) Screw again by hand the metal stopper in the original position on the regulator.
Operating in this way the gas regulator is converted for use with the other gas/pressure.
