How can this be converted to use with natural gas?
According to Rinnai they have a model that specifically uses natural gas but if you need to convert an existing unit the three things you will need are a burner assembly, a manifold assembly, and a conversion rating plate.  Thier recommendation is to contact them directly so that you they can get you an exact model number for the kit that will best fit your needs The phone number is 800 621 9419 for engineering or technical support Once they give you a part number feel free to email me directly at and I can get the unit processed for you.
