Description

The Atwood / Dometic 31077 Furnace Burner Orifice is a precision gas metering component for Atwood RV furnaces. This #49LP propane orifice regulates LP gas flow to the burner assembly for proper combustion and efficient operation.

Replacement may be necessary if your RV furnace exhibits weak flames, ignition problems, delayed ignition, or poor heating performance due to a clogged, damaged, or worn orifice. This part is a direct replacement for Atwood furnace burner orifices used in many models.
