I have spliced in this fitting.... for my Olympic heater....
But I'm pretty sure the Mr. Heater is set up for propane direct from the
canisters which do not have pressure regulators.... that means Mr. Heater
has a pressure regulator built in... and I believe it would not run properly
(if at all) on the 11 w.c. inches or pressure which is what you will have
after your pressure regulator.... so I think you would have to get your
propane from between the tank and the pressure regulator... not after the
regulator...
