FAQ

This filter is designed for use with Mr. Heater Buddy-series propane heaters when connected to a bulk propane cylinder via a hose assembly. It is compatible with Portable Buddy, Big Buddy, Tough Buddy, and Hunting Buddy heaters, as well as hose and connector part numbers F273701, F273702, F232000, F274800, F23203, 6351206, 6351207, and 6351200. Please verify your fitting style and consult your heater owner's manual before ordering.
The primary part number for this filter is F273699. While it is frequently used in conjunction with hose and connector part numbers F273702, F232000, F274800, F23203, F273701, 6351206, 6351207, and 6351200, these are related components rather than alternate filter part numbers. F273699 is the specific identifier for this filter.
This inline propane fuel filter installs between the heater and a bulk-tank hose assembly. It traps oily residues and contaminants that may travel from large propane cylinders through the hose and into the heater's regulator or burner system. Utilizing this filter helps prevent performance issues caused by fuel contamination.
We recommend replacing the filter annually if you use your heater regularly with bulk propane cylinders and hoses. You should also replace it if the heater exhibits signs of contamination, such as weak performance, inconsistent operation, or difficulty staying lit, provided you have already ruled out other fuel supply or hose issues.
A restricted or contaminated filter can impede fuel flow or allow debris to reach the heater. Indicators of a saturated filter include hard starting, reduced heat output, intermittent shutdowns, or unreliable operation when connected to a 20 lb. or larger propane tank. Because these symptoms can also stem from issues with the hose, regulator, tank valve, or the heater itself, we recommend inspecting the filter as part of your overall system troubleshooting.
This filter is intended for use when connecting your heater to a bulk cylinder and hose assembly. The filter is designed to address contaminants introduced through extended hose lines and bulk-tank setups; therefore, it is typically used with 20 lb. or larger propane tanks rather than when connecting directly to a 1 lb. cylinder.
