A heater assembly can be used with a gas appliance. The gas appliance can be a dual fuel appliance for use with one of a first fuel type or a second fuel type different than the first. The heater assembly can include a housing, and an actuation member. The housing has a first fuel hook-up for connecting the first fuel type to the heater assembly, a second fuel hook-up for connecting the second fuel type to the heater assembly, and an internal valve. The actuation member can control the position of the internal valve based on whether the first or the second fuel hook-up is used.

1. A heater assembly for use with one of a first fuel type or a second fuel type different than the first, the heater assembly comprising: a housing comprising: first and second fuel hook-ups, the first fuel hook-up for connecting a first fuel type to the heater assembly and the second fuel hook-up
1. A heater assembly for use with one of a first fuel type or a second fuel type different than the first, the heater assembly comprising: a housing comprising: first and second fuel hook-ups, the first fuel hook-up for connecting a first fuel type to the heater assembly and the second fuel hook-up for connecting a second fuel type to the heater assembly; andfirst and second fuel outlets;wherein the housing has a first chamber defining a first flow path from the first fuel hook-up to the first fuel outlet and a second chamber defining a second flow path from the second fuel hook-up to the second fuel outlet, the first and second chambers being separate within the housing;an actuation member comprising a rod configured for linear advancement from a first position to a second position, the actuation member having a first valve member positioned within the first chamber and the first flow path and coupled to a second valve member positioned within the second chamber and the second flow path, the actuation member having an end that extends at least partially into the second fuel hook-up, wherein the actuation member is configured such that in the first position one of the first flow path and the second flow path is open and the other is closed, and connecting a fuel source to the heater assembly at the second fuel hook-up moves the actuation member from the first position to the second position which opens the closed flow path from the first position and closes the open flow path from the first position. 2. The heater assembly of claim 1, wherein in the first position the first flow path is open and the second flow path is closed. 3. The heater assembly of claim 1, further comprising a spring operatively coupled to the actuation member to bias the actuation member towards the first position. 4. The heater assembly of claim 1, wherein the housing comprises a first seat configured to engage the first valve member in order to substantially close the first flow path. 5. The heater assembly of claim 1, wherein the heater assembly further comprises a pressure regulator and the second flow path passes through the pressure regulator before joining with the first flow path. 6. The heater assembly of claim 1, wherein the first fuel hook-up is a male inlet. 7. The heater assembly of claim 1, wherein the second fuel hook-up is a female inlet. 8. The heater assembly of claim 1, wherein the housing is an inlet valve housing that comprises a first outlet and a second outlet. 9. The heater assembly of claim 8, wherein the first flow path and the second flow path are not in fluid communication with each other within the inlet valve housing. 10. The heater assembly of claim 8, wherein the first flow path passes through the first outlet before joining the second flow path, and wherein the second flow path passes through the second outlet before joining the first flow path. 11. The heater assembly of claim 1, further comprising a plurality of burners connected to the main flow path. 12. The heater assembly of claim 11, further comprising a control valve associated with each of the plurality of burners. 13. A heater assembly for use with one of a first fuel type or a second fuel type different than the first, the heater assembly comprising: a main fuel line;a juncture having an end coupled to the main fuel line, a first juncture inlet and a second juncture inlet, the first and second juncture inlets in fluid communication with the end;an inlet valve housing having first and second fuel hook-ups, the first fuel hook-up for connecting a first fuel type to the heater assembly and the second fuel hook-up for connecting a second fuel type to the heater assembly;a first flow path from the first fuel hook-up to the first juncture inlet and a second flow path from the second fuel hook-up to the second juncture inlet, wherein the first flow path is separate from the second flow path;an actuation member comprising a rod configured for linear advancement from a first position to a second position within the inlet valve housing, the actuation member having an end that extends at least partially into the second fuel hook-up, wherein in the first position wherein the actuation member substantially closes the second flow path and in the second position the actuation member substantially closes the first flow path, wherein connecting a fuel source to the heater assembly at the second fuel hook-up moves the actuation member from the first position to the second position;a pressure regulator within the second flow path between the second fuel hook-up and the second juncture inlet; anda burner connected to the main fuel line. 14. The heater assembly of claim 13, wherein the first fuel hook-up is a male inlet. 15. The heater assembly of claim 13, wherein the second fuel hook-up is a female inlet. 16. The heater assembly of claim 13, further comprising a control valve associated with the burner. 17. The heater assembly of claim 13, wherein this is no pressure regulator within the first flow path between the first fuel hook-up and the first juncture inlet. 18. The heater assembly of claim 1, further comprising a valve having a spring, the valve being disposed within the housing. 19. The heater assembly of claim 18, wherein the valve is a pressure regulator.
