Dual fuel heater with selector valve

Abstract

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 at least one pressure regulator, a housing, and an actuation member. The housing has a first fuel hook-up for connecting the first fuel type to the heater assembly, and a second fuel hook-up for connecting the second fuel type to the heater assembly. The actuation member can control a flow through the heater assembly based on whether the first or the second fuel hook-up is used.

AI Technical Summary

Benefits of technology

[0013]In some embodiments, a heater assembly can be configured for use with one of a first fuel type or a second fuel type different than the first. The heater assembly can comprise a housing, a first actuation member and a second actuation member. The housing can have a first fuel hook-up for connecting a first fuel type to the heater assembly, a second hook-up for connecting a second fuel type to the heater assembly, a first outlet in fluid communication with both the first and second fuel hook-ups, a first inlet, a second outlet, and a third outlet. The first actuation member can have 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. In the first actuation member first position, fuel flow through the first fuel hook-up and the second outlet is prevented. In the first actuation member second position, fuel flow through the first fuel hook-up and the second outlet is permitted. The second actuation member can have 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. In the second actuation member first position, fuel flow through the second fuel hook-up and the third outlet is prevented. In the second actuation member second position, fuel flow through the second fuel hook-up and the third outlet is permitted.
