User interface for heater

1. A heater comprising:

a cylindrical housing with an inlet end, an outlet end, and an axis extending between the inlet end and the outlet end;

a combustion chamber positioned at least partially within the cylindrical housing;

a base coupled to the cylindrical housing, the base defining a bottom surface of the heater; and

a user interface operable to control combustion within the combustion chamber;

wherein the axis is positioned between the base and the user interface; and

a grill positioned at an inlet end of the cylindrical housing, the grill including a top surface positioned above the axis, and

wherein the user interface is positioned on the top surface of the grill.

2. The heater of claim 1 , wherein the grill includes a plurality of openings, and wherein the axis extends through the grill.

3. The heater of claim 1 , wherein the base defines a first plane on which the heater is supported, and wherein the user interface defines a second plane that is oblique relative to the first plane.

4. The heater of claim 1 , wherein the user interface includes

a first user input configured to turn a main power supply on and off,

a second user input configured to energize an ignitor, and

a third user input configured to adjust an amount of fuel supplied to a burner.

5. The heater of claim 4 , wherein the main power supply is a battery pack insertable through a rear surface of the base.

6. The heater of claim 4 , wherein the user interface further includes a lock-out solenoid with a plunger that extends from a solenoid housing, and wherein the plunger is configured to interfere with and block movement of the second user input.

7. The heater of claim 1 , wherein the user interface includes a visual indicator.

8. A heater comprising;

a cylindrical housing;

a combustion chamber positioned at least partially within the cylindrical housing;

a base coupled to the cylindrical housing, the base defining a bottom surface of the heater;

a user interface operable to control combustion within the combustion chamber, wherein the user interface is positioned on a top surface of the heater, opposite the bottom surface; and

a grill positioned at an inlet end of the cylindrical housing, wherein the grill includes a plurality of openings, and wherein the grill defines the top surface on which the user interface is positioned.

9. The heater of claim 8 , wherein the base defines a first plane on which the heater is supported, and wherein the user interface defines a second plane that is oblique relative to the first plane.

10. The heater of claim 8 , wherein the user interface includes

a first user input configured to turn a main power supply on and off,

a second user input configured to energize an ignitor, and

a third user input configured to adjust an amount of fuel supplied to a burner.

11. The heater of claim 10 , wherein the main power supply is a battery pack insertable through a rear surface of the base.

12. The heater of claim 8 , wherein the user interface includes a visual indicator.

13. A heater comprising:

a cylindrical housing with an inlet end, an outlet end, and an axis extending between the inlet end and the outlet end;

a combustion chamber positioned at least partially within the cylindrical housing;

a base coupled to the cylindrical housing, the base having a bottom surface defining a first plane on which the heater is supported;

a user interface operable to control combustion within the combustion chamber, the user interface defining a second plane that is parallel to the axis of the cylindrical housing; and

a grill positioned at the inlet end of the cylindrical housing and includes a plurality of openings,

wherein the axis extends through the grill, and

wherein the user interface is positioned on the grill.

14. The heater of claim 13 , wherein the user interface is positioned on a top surface of the grill.

15. The heater of claim 13 , wherein the user interface includes

a first user input configured to turn a main power supply on and off,

a second user input configured to energize an ignitor, and

a third user input configured to adjust an amount of fuel supplied to a burner.

16. The heater of claim 15 , wherein the main power supply is a battery pack insertable through a rear surface of the base.

17. The heater of claim 13 , wherein the second plane is oblique relative to the first plane.
