According to the installation manual for the Marvin Direct Vent Propane Heaters, the minimum permissible propane gas pressure is 11" WC (water column), which our MB Sturgis Single Stage Regulator # 108072 can supply.

If you are connecting the heater directly to your 100-lb tank, then you will also want a pigtail hose # 37207-30865, to go from the tank valve to the regulator and a supply hose with a 1/4" male NPT fitting to connect at the regulator and a 3/8 female NPT fitting to connect to the heater inlet long enough to reach your heater.
