Valve assemblies for heating devices

摘要

In certain embodiments, a valve assembly can comprise a housing, a valve body, a first burner nozzle member and a second burner nozzle member. The housing can define an oxygen depletion sensor (ODS) inlet and a burner inlet. The valve body can be positioned within the housing and configured to rotate between a first position for a first fuel type and a second position for a second fuel type different from the first.

主权项

1. A valve assembly for a dual fuel heater comprising:
a housing defining an oxygen depletion sensor (ODS) inlet and a burner inlet; a valve body positioned within the housing and configured to rotate between a first position for a first fuel type and a second position for a second fuel type different from the first fuel type, the valve body comprising:
a single ODS channel in the valve body; a first burner channel in the valve body; and a second burner channel in the valve body; wherein the valve assembly is configured such that rotation of the valve body between the first position and the second position changes the relationship of the single ODS channel to the ODS inlet and also changes the relationship of the first and second burner channels to the burner inlet; a first burner nozzle member connected to the housing; and a second burner nozzle member, wherein the second burner nozzle member is internal to the valve assembly.
