First Claim
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 pressure regulator having a first position and a second position;
a housing having first and second fuel hook-ups, the first fuel hook-up for connecting the first fuel type to the heater assembly and the second hook-up for connecting the second fuel type to the heater assembly;
an 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 which causes the pressure regulator to move from the first position to the second position;
wherein the pressure regulator in the second position is configured to regulate a fuel flow of the second fuel type within a predetermined range.

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.
