Product Description

This is an authentic OEM replacement part sourced directly from the manufacturer. This is a common replacement part for un-vented heaters. Essentially the pressure regulator is a valve that controls the pressure level of propane traveling to your heater. This valve will automatically cut off the flow of gas when it reaches a certain pressure. The goal of the pressure regulator is to match the heaters need for fuel to the amount of fuel that is getting supplied to the heater, the regulator works to try and limit the risk of a propane build-up inside the heater. Due to constant contact with fuel this part may wear down over time and become less effective, at which point the heater will not operate effectively because it may not be receiving the appropriate level of fuel it needs to run. This replacement part is sold individually.
