Heating assembly

摘要

A heating assembly can be used with one of a first fuel type or a second fuel type different than the first. The heating assembly can a include housing have a first actuation member and a second actuation member. The first and second actuation members can be positioned within respective first and second fuel hook-ups. The first and second actuation members can be configured such that connecting a fuel source to the heater assembly moves one of the actuation members from a first position to a second position to control flow through the heating assembly.

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 first pressure regulator configured to regulate a fuel flow of a first fuel type within a first predetermined range a second pressure regulator configured to regulate a fuel flow of a second fuel type within a second predetermined range different from the first; a housing comprising:
a first fuel hook-up for connecting the first fuel type to the heater assembly, the first fuel hook-up configured to direct fuel flow to the first pressure regulator;a second hook-up for connecting the second fuel type to the heater assembly, the second fuel hook-up configured to direct fuel flow to the second pressure regulator;a first outlet in fluid communication with both the first and second pressure regulators;a first inlet;a second inlet;a second outlet;a third outlet; anda fourth outlet; a first actuation member having an end located within the first fuel hook-up and having a first actuation member first position and a second position, the actuation member configured such that connecting a fuel source to the heater assembly at the first fuel hook-up moves the actuation member from the first actuation member first position to the second position,
wherein in the first actuation member first position, fuel flow through the first fuel hook-up and between the second inlet and the fourth outlet is prevented and in the first actuation member second position, fuel flow through the first fuel hook-up and between the second inlet and the fourth outlet is permitted; a second actuation member having an end located within the second fuel hook-up and having a first position and a second position, the actuation member configured such that 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,
wherein in the second actuation member first position, fuel flow through the second fuel hook-up between the first inlet and the third outlet is prevented and in the second actuation member second position, fuel flow through the second fuel hook-up and between the first inlet and the third outlet is permitted.
