OK See if this will work.
Start with a 20 lb propane tank,
attach a 2 stage rv (11 in WC) hortizontal regulator with male POL and female 3/8 NPT,
attach rubber hose (Mr. Heater 15 ft) with 3/8 male NPT and 3/8 female NPT,
attach brass 1/2 union with 3/8 male NPT and 3/8 male flare.
At the hot water heater 3/8 line, slide a 3/8 brass flare nut on, then flare the line (Yes, Even though it has been 35+ years since I used a flaring tool, I remember forgetting to put the flare nut on FIRST, lol.)
Last,attach the flare nut to the 3/8 male flare side of the union.
After several on-line searches, I could not find a long enough hose that had a 3/8 male NPT (for the Regulator) and a 3/8 male Flare (for the Flare nut).
Any problems? I should add that locally, If Lowes, Tractor Supply,or maybe NAPA does carry what I need then I have to order it.
