using a 100lb propane tank for mr heater 4500lp, wanted to know what type of regulator to use at the tank , can I use same type used for typical gas grill?:
Yes. I used a regulator kit from Mr. Heater brand that I got from Northerntool.com. Then it was off to Home Depot for a small fitting to complete the deal. It's basically the same regulator that's on a BBQ or portable heater, etc.
