a second means adapted to form a second flow of an air/gas mixture, feed the at least one main burner with said second flow of the air/gas mixture and allow said first flow of the air/gas mixture to exit from the at least one main burner;
a gas valve assembly mounted to the housing and comprising a gas valve adapted to selectively:
prevent the first flow of the air/gas mixture to exit from the at least one pilot burner and prevent the second flow of the air/gas mixture to exit from the at least one main burner;
allow the first flow of the air/gas mixture to exit from the at least one pilot burner and prevent the second flow of the air/gas mixture to exit from the at least one main burner; or
allow the first flow of the air/gas mixture to exit from the at least one pilot burner and allow the second flow of the air/gas mixture to exit from at least one main burner,
said gas valve assembly cooperating with at least one knob movable along and around an axis for selectively operating the gas valve, controlling the flow of the second flow of the air/gas mixture, and operating a means to ignite the gas/air mixture exiting from the at least one pilot burner;
a gas piping connecting the gas pressure regulation system to the gas valve,
a gas piping connecting the gas valve to the first means adapted to form the first flow of an air/gas mixture, and
a gas piping connecting the gas valve to the second means adapted to for the second flow of an air/gas mixture,
the gas valve being a thermostatic valve, said thermostatic valve being provided with means cooperating with a temperature sensor and adapted to open and close the gas valve for the control of the flow of the second flow of the air/gas mixture exiting from the at least one main burner.

### Claim 2 (depends on 1)

The portable heater according to claim 1, further comprising a support assembly comprising at least one first member provided with a first portion and a second portion, the first portion being adapted to be connected to the housing and the second portion defining a stop positioned close to a portion of the thermostatic gas valve opposite to the knob; and
wherein the portion of the thermostatic gas valve opposite to the knob is adapted to engage the stop when a pressure is applied to the knob by a user to move said knob along the axis.

### Claim 3 (depends on 2)
