Abstract
A heating assembly can include a gas hook-up and a pressure switch. The pressure switch can be in fluid communication with the gas hook-up and be movable at a predetermined threshold pressure from a first position to a second position. The pressure switch can be further configured such that if a fuel is connected to the gas hook-up that has a delivery pressure either above the predetermined threshold pressure in one situation or below the predetermined threshold pressure in another, the fuel will act on the pressure switch to move it from the first position to the second position.
Claims20
A heater assembly, comprising:
- a housing comprising:
- a first gas hook-up;
- a first pressure regulator;
- a first flow path extending between the first gas hook-up and the first pressure regulator;
- a second flow path;
- and
- a pressure switch in fluid communication with the first gas hook-up upstream from the first pressure regulator, the pressure switch being movable from a first position to a second position when a delivery pressure of a fuel at the first gas hook-up is within a predetermined delivery pressure range;
- wherein the pressure switch is configured such that if the fuel connected to the first gas hook-up has a delivery pressure within the predetermined delivery pressure range, the fuel will act on the pressure switch to move it from the first position to the second position which movement opens or closes the second flow path through the housing.

A heater assembly, comprising:
- a first gas hook-up;
- a first pressure regulator;
- a first flow path extending between the first gas hook-up and the pressure regulator;
- a second flow path;
- a valve positioned within the second flow path;
- and
- a pressure switch in fluid communication with the first gas hook-up upstream from the first pressure regulator, the pressure switch being movable from a first position to a second position when a delivery pressure of a fuel at the first gas hook-up is within a predetermined delivery pressure range;
- wherein the pressure switch is configured such that if the fuel connected to the first gas hook-up has a delivery pressure within the predetermined delivery pressure range, the fuel will act on the pressure switch to move it from the first position to the second position which movement opens or closes the valve in the second flow path.
