        Q:Can this be installed by homeowner?

        1 Answer
        Answer This Question

        A:  Hello Dave, Rinnai does recommend the installation be completed by a licensed and trained professional but is not required. When installing a Rinnai tankless water heater, a licensed technician would ensure proper venting, gas pressures (both the supply pressure and internal calibrations of the lo and hi fire settings), water pressures, electrical and drain lines are done properly. A locally licensed professional would also be expected to know and follow any local codes and/or pull any required permits. Please be advised that if there are any manufacturing defects that need to be resolved under warranty, we do require that a licensed professional is involved to assist with diagnosis and repairs needed. Thank you, Brittany

          I ordered it based on the model number one of your folks gave me. I am a natural gas user and this unit was for propane. What a nightmare. We had to get a conversion kit but it took hours to troubleshoot and figure it out. If your person would have ask me propane or natural gas it would have saved a lot of issues. Oh well we finally figured it out and love the unit.
